  • I can't even imagine a woman seeing your apartment for the first time. "How do I turn on the lights?" "Well, all you have to do is stand here, raise your hand for 5 seconds, and a linear actuator will come out of the wall. Take note on the EL wire around the borders. Their are 17 easy to use compartments containing switches, which open hidden drawers. Once the drawers are open, you'll notice it can get quite dark, note the "natural" light illuminating the area I made from a broken laptop screen. Once you've made your way into the hidden drawers, simply connect your cell phone via this easy to use USB type c dongle. Once connected, connect to the wifi and download the app, "light-switch". And, that's all. P.S. Take note on the carbon fiber wrapped mdf board holstering the USB dongle".

    • to update this change carbon fiber mdd to polished brass

    • 😂😂😂😂😂🙌🙌

    • @Xander McKay Logistics.

    • I laughed out loud… for real… brilliant, and I did hear his voice… so funny because as he narrates SUPER complex procedure… there is this assumption that we all are just following along “ah… so simple!”… when really we are feeling dumber and dumber as it goes… lol

    • Mvp! Awesome!

  • shout out to the kid who tried this on their mom's laptop and actually succeeded

    • @Darwin B great

    • Well i dont wanna toot my own horn

    • 43676

    • Me who took a 12year old dads laptop and made it into my youtube chat looking monitor

    • Not that hard because this guy makes it easy, he's awesome

  • Great project. I haven't seen anyone do anything like this themselves. You've earned yourself a new subscriber, a like and this comment. I hope the ILaward algorithm treats you well!

  • Neat. The hinge design folding backwards seems interesting as a presentation option. I'd be a bit concerned about damaging the screen while transporting it though, as it's exposed constantly to the outside. I would consider the merits of a pop-up/slider design as an alternative to the hinge design. You don't get the neat presentation mode, but I suspect it would be sturdier. Additionally, the top and bottom screen angles would always match... for better or worse.

    • @wiggenvan yes definitely a cool concept. Just wouldn't be safe with me lol

    • @Arnie I mean, if done from a large manufacturer, something like this would probably have hardened glass screens like tablets do. Could be interesting from a compact/productivity point of view

    • just put a glass on it, I'll do it on my primary screen because yes

    • I was cringing about this throughout the video ( typing this on a laptop with a smashed screen right now haha)

  • Would be cool to add four things: 1. Use an old laptop screen and retain its bezel / casing. 2. Have the screen slide up instead of fold out. This way it would have a smooth back and a professional look. 3. Hide the controller inside the laptop by removing an unused optical drive to make space for it. 4. Power it from the laptop battery.

  • This is brilliant, I've always wanted something like this but never thought about how (technically) easy it could be.

    • Just plug an LCD monitor into the laptop and make a stand of the proper height. Plug and play dual monitors. You can get 24" monitors cheap now.

  • Well done sir! I've been thinking about doing this exact thing for a long time, for the same reasons. It should absolutely be a thing. Asus' "Zenbook Duo" thing is no good because it requires looking down even further to see the secondary screen. I think it's worth mentioning that you can buy a "portable monitor", which is basically a laptop screen + controller board. This would be a good starting point to building a monitor that sits on top of your laptop screen (you could strip it down to just the display and controller board, and go from there)

  • This is amazing! I am very impressed on how Matt constructed the dual screens on a laptop! I truly believe this innovative idea will catch on.

  • I love the way you show your trial and errors in the videos.

    • Yeahhhh, but at the same time I really question his end result in the trial-and-error process. There are some really cool epoxy DIY projects out in the world, but they are highly specific in purpose and design philosophy. When making something like a laptop screen, the last thing I would opt for is to make my second screen edges out of glossy plastic. They looked fine just sanded down both times. And if he considers that looking too unfinished, I would go for any type of pattern design (some dotted lines on the innermost edge, maybe), instead of just making the whole thing look like a cheap Lenovo case.

    • You read my mind! Helps us relate to the dude instead of feeling we have to be perfect to take such things on. I want to try this!

    • Yap, I loved that too..

    • @Mikael I mean, if you can do it better you can always link us to your video...

    • Word up

  • For the border, *maybe* you could use car door bumper trim, or some kind of pre-existing gasket from car or house opening. It all depends on the thickness of the screen+backing that you are trying to cover.

  • Really cool project! I'm concerned about damaging the screen in transport though. This is really why laptops fold the screens inwards, so unsure how to tweak this project in similar regard.

  • I did something similar to this years ago with my old netbook monitor and some 3d printing, it was the first semi complicated design project I did I was really proud of it.

  • Hey there, I have a question about the type C PD. I made this pretty much exact thing but used the exsisting casing for the laptop I had and mounted everything to that with threaded inserts from the lower half. Everything works as it should and is actually a bit slimmer but I want to add in the type C PD you show in the video. I was curious if of the 12v output resets every power loss or keeps the memory? Would a stepdown controller work better if it resets every time? Thanks for the help and great video.

  • A tip to make your 3D prints smoother: in cura, enable the option called "ironing". it makes it really really smooth on top! also, bottom layer pattern to concentric instead of zigzag makes it waaay nicer!

    • what about "baking"?

    • And calibrating your printer also helps.

  • Great work! what gauge / thickness / dimensions do you use for your aluminium sheeting? and any other flat bar/ right angle aluminium that you use. Appreciate it!

  • It's a good idea I've been thinking about doing something like this for a while. I Wouldn't need the powerbank because I only really use my laptop plugged in to the mains so I could easily get the power from the USB C. Then you could easily just 3d print a housing for the driver board and have it on the desk connected by cables. As to mounting it on the top, that's a great Idea but I think I'd rather just have it clip on or have a much thinner hinge. Thanks you've given me a lot of ideas.

  • Thanks! I just finished the dual screen setup and it's amazing!

    • Can you attach photos by uploading them to somewhere

  • I tried this set up a long time ago without fixing the second monitor on the top and found it really uncomfortable and hurt my neck over time. It is better when the screen on the portrait position and on the left side of the main monitor. It helps read pdfs, ebooks, longer view for coding (if you are a programmer) and browsing the net as well.

  • Samsung: "We made a phone with extra screen real-estate" Matt: "Hold my Cloud unit" Honestly though Matt, you push expectations. NEVER CHANGE dude.

    • matt: hold my broken laptops

    • #Lenovo Make it 6 display! *LoL With the recent Lenovo laptop with USB type C and screen spare part.

    • @Luuk Verhoek whatever makes you happy.

    • @El Fedora Usado I said not alot of people would try to make this, you corrected me by saying alot would be using wrong numbers. But whatever, i accept your apology

    • @Luuk Verhoek 1st. I did not "correct" you. Just pointed out that, even using the percentage you yourself gave, the objective amount of people who potentially made the project still seems a legitimate reason, in my opinion, for the author to post the video. 2nd. I did the math mentally, but when I typed 320 actually added the extra zero for 3200 in my mind by mistake. I was doing several other things at the same time, and replying to your comment was pretty low on priority (no slight intended, by the way) to pay much attention to what I was typing, much less double checking a rushed mental calculation, even as simple a one.

  • Great project. Just curious: The link to the powerbank nowhere mentions 12V 3A output (which would be PD profile 3 AFAIK). The best PD bank from charmast has max 18W output, which would be 12V 1,5A. I am somehow hesitant to source ~27Ah capacity batteries from china that do not explicitly mention that they will behave well under 36W of load

  • Very slick! I have a laptop with a 2nd display as well for art work. I overlaid my Huion Kamvas pen display over the 17" laptop's keyboard and use the laptop screen as a reference display while drawing on the Kamvas. So, I can just glance up at the reference instead of to one side. Since the keyboard/trackpad is covered, I use a wireless keyboard/trackpad on the desk in front of the pen display.

  • Hey, so I have a question about those hinges! I'm looking to add an extra screen to my laptop using a tablet and some software, but I want to attach it so that It comes out as another screen on the side, rather than on top. I watched the video (great btw) and was wondering if those hinges were designed to stop at ~180 degrees, or if they will keep going to essentially 360 degrees. Thanks,

  • Muito pratico. Fiz dois enquanto assistia o vídeo.

  • When you made your first diy secondary screen for laptop I took apart my old laptop with intention to make exactly what you did now. I stopped the project because I didn't know how to figure out the hinge so I don't damage my main laptop. Thanks to this I think I'll return to my idea :D Thousad times thanks!

    • @Damion Lee That's exactly how the DUEX Duo screen you can buy on Amazon works. It just slides out the side of the laptop instead of above the screen.

    • If you are going to use a power bank and you don't provide more support than a kick stand (or relocate the bulk of the weight to the base of the notebook) you will still damage your hinges. The amount of added pressure and torque from attaching this to the back of the screen will far exceed their design. Doesn't matter for his hinges, they are already blown. But while the kick stand will help with the added rotation load on your main hinges, it will not support the weight pushing down. Adapt a stand that will support the added weight (or move it underneath the base of your notebook), and you'll be fine.

    • Do it man! You learn all sorts of things along the way :)

  • If you're going to attempt following this tutorial, make sure your laptop's GPU can handle a permanent 2nd monitor, if you don't have a lot of RAM then upgrading it is recommended by me as well

  • I am in the process of making one of these screens. Just received the controller board. I have discovered that a PSU from an old Virgin Media router powers the screen fine. The PSU is very compact - the sort where the transformer is built into the plug housing. It only takes up a bit of space and will save me wiring up a USB-C power board and using a power bank.

  • This is a great video. Informative, clear, and well filmed . . . like all of your videos. Well done!

  • Love it - how would you rate the picture quality of your recommended screen? If picture quality is a main focus, would you recommend a more expensive panel?

  • I love this idea, I do think it needs a bit of work though, as the reason laptops work so well is that they shield themselves. Perhaps if it folded inwards as well as outwards and the inwards one was to close it in the case and clasp it shut, then the opposite for mirror mode and if you only want one screen.

  • 4:47 Only means you need to tweak your printer. It doesn't have to be that bad. Even I as a beginner in §D printing had much better results ... even in PETG which is harder to print than PLA (which is from the looks what you used here). Edit: 4:59 Oh, ok. ABS, it was. You should go over to more modern materials, tho. As they don't give out as much vapors while printed.

  • Oh my god, I've been looking for that usb-c power board without even knowing! I was trying to find a way to power the screen through the laptop, or a separate portable output that could supply the 12v, but I didn't really know how. This is a total game changer!

  • 7:02 what kind of wire is being used for a soldering project like this? Is there a certain thickness to be thought of ? Thanks for answering

  • I would suggest that people buy a laptop stand such as of "Amazon Basics" to bring the screen to a height of the normal view as explained in the video. Also if companies think of this design it might just be impossible to fold two screens with the keyboard and make it slim enough. However this is helpful for those who can't buy a dual desktop setup and has the budget to buy a decent laptop.

    • Yes I agree with you. You could do the same project but instead of having it attached with bulky hinges and velcro it would be a separate, neater setup that you can just stand in exactly the same position behind.

  • Ingenious set-up, you do come out with interesting budget stuff thanks and this is no exception. I wonder what benefit you could get from 3 extra screens?

    • Traders wud welcome it. Studio people too.

  • You can also use old laptop hinges and mount the on the opposite side!:)

  • For the hinge, could you use a piano hinge and use spacers/washers to create the spacing you need? Also, for the new monitor edging, I bet you could use car door trimming. They come in colors and chrome. Great video!

  • Hey! So, I was looking for a solution like this so badly when i was working on my laptop for extended amounts of time. I ended up buying the Lenovo ThinkPad M14 external monitor, but I would LOVE a production mount to put it OVER my laptop instead of next to it. Do you think it is something that can be easily done? Can you do a similar project using the M14 monitor? This is the monitor:

  • Is there any way to use the laptop screen without dissasembling the casing and having to build another one? I mean, just disconnecting the screen from the motherboard and taking the whole top portion of the laptop (plastic casing and all) with the wires sticking out and connecting them to something in order to get it working.


  • This guy is literally the very definition of a product engineer / designer. Samsung, Apple, Lenovo, Dell, HP...whoever...just some tech company out there would definitely want to hire this guy.

  • DIYPERKS: MaYbE a MaNuFaCtUrEr WiLl cOmE aLong aNd MaKe iT. Asus: *attaches the screen to the keyboard*

    • @Xanderplayz Yeah Windows 11 is more hype anyway

    • @Andrew Gardner it was cancelled

    • @Zaf - the closest to this was Intel's Project Honeycomb. Asus' iteration is lovely, but it does make several ergonomic compromises. Even though it has an even wider overall second screen than most of the portable attachable ones and it's a touchscreen, it doesn't give a very good user experience for reading, unless you're using the Numpad App. Furthermore, the untested Windows updates may interfere with the intended intuitive functions. DIYPERKS' idea, though borrowed, is still more ergonomic

    • @FlashPaperGrind # that was just a prototype that never actually made it into production

    • Why not just use a tablet and spacedesk, look at that contraption.

  • I would like to add that in-place of a battery backup you can also plug your laptop into a USB-C, Thunderbolt, or other kind of dock (attached in the same place the battery is positioned in this video), and then output the USB-C from that dock to the 2nd monitor, plus get additional connectivity from the dock itself, such as more ports, etc. For docks and laptops that support it, this dock can also be used as a way to charge the laptop with a USB-C power input to it (again, depending on if the dock and laptop supports it), keeping clutter down.

  • Sensational! Congratulations on the excellent work!

  • Qué pasada tío. Muy interesante, enhorabuena por la idea y la ejecución.

  • This is so underrated. Cool design, also you have really thought about different ways of reusing it.

  • Great and fun recycling project, and I love your work! This particular one unfortunately does not seem commercially feasible as for the cost it takes to buy the parts, one can easily buy a used monitor. If it was touchscreen and ran android then it could be fun to build.

  • Excellent prototype, I hope that a company or investor sees this publication and realizes the potential that is presented here, well, I would buy an equipment like that, it would be very very useful, it would be a little more expensive laptops, but it would be worth it.

  • I'm so happy! You saved my project! I was struggling with power delivery and that board will be perfect! Im going to buy a million of those! Thank you!

  • I loved this video so I tried it myself. I made my first monitor and it lasted a few months. I think the power supply was a little off because it died one day and the power light blinks orange. So I decided to try again. Both of the monitors I am working on now are too dark. I can't figure out what is causing this issue. Power supply? Wrong control boards? Or user error? Any ideas or suggestions?

  • Very nice... congrats for this idea A other idea is, to use a slide instead of hinges... So is the display a bit saved from scratches.

  • Awesome. Now come up with a version that also includes left and right foldable monitors and I swear I'll do it!

  • I wonder, is this possible with more monitors? Having one to each side as well and using a wall power source? You can never have too much screen space.

    • Cant see that it wouldn't - your limitation is actually the number of display ports on the machine / laptop itself. If you have the ability to connect 4 screens (regardless of what those screens actually are) then it will work just fine and windows will detect each of them.

  • I would also like to point out that now you can also reuse old tablets and install screen sharing server like Spacedesk on your windows(only) machine and use it as secondary monitor. But with your design you can just use it with anything from win to linux to smartphones.

  • 5:50 Is it okay if I mount the board directly onto the aluminum without using the PCB pillars? Or are the pillars necessary as to keep the circuit board a few distance away from aluminum?

  • By far the best DIY multi screen laptop on the internet. great video as always.

    • I feel like USB C makes a lot of projects like this possible. Now that there are portable monitors with video AND power through USB C, you could make a removable hinge for one of those displays and when you need it just attach it to the top of your laptop and plug it in via usb c.

  • Only found this channel a day ago and have subbed & binged, unashamedly. You're a talented guy, amazing channel, it's very entertaining to watch. Clever and resourceful -- not your typical DIY stuff you usually see, real, useful stuff - amazing.

  • Never knew Theon Greyjoy was an engineering genius.

  • I love how some of us dont have money or tools to do this whatever it's still cool to watch

  • That was incredible. Well done. Thinking of a screen setup which can be daisy-chainable.

  • Awesome and bonkers at the same time, well done, this is one of the best inventions yet, a friend of mine is already using led TV screens as lights based on your videos 👍🏻👍🏻👍🏻👍🏻👍🏻

  • I have done it for mine, but with a 4k Screen(Because of porf. Video editiong, and it works like a charm. But I have also mounted some speakers to it, thanks for the great idea

  • This is absolutely brilliant!!!! I have UPS by me making up the hinge and covers tomorrow, and I am looking for these parts or something similar through amazon. as Ebay will take potentially 1.5 months to get here.

  • Hi, for the soldering in the display boards voltage input did you connect the wires to the 12v or somewhere else?

  • I can see where this could be useful, including having it go either to the left or right of the laptop screen (vs. up). What I don't understand is why you didn't just have it run off the USB C port on the laptop to power it? I don't know what kind of display time you'd get off the second screen from an external pack, but if you've got a spot to plug the laptop in, power would not be an issue and it would make the second screen a bit more streamlined. Nice project. :)

    • at 8:49 the text on screen says his laptop doesn't have the correct port.

    • He said that he doesn't have USB C port in his laptop. But yeah, you can do it

  • You will be a magician now... love your DIY projects

  • Found it lately. Many congrats for such a seriously amazing channel.

  • The Thinkpad w700ds had dual monitors, one smaller vertical display slid out from the right side of the main display. The extra display was pretty poor quality though and offered no ergonomics benefit, still neat a neat concept. Using a laptop with a display directly above it on my desk, I can confirm that a dual monitor setup is much better in a vertical layout than horizontal because you can see both monitors in your line of vision without having to turn your head side to side.

  • tip for your prints, decrease the line width in your slicer, if you got .4mm try .38

  • The idea is good, but I have a few concerns... a, During transportation, an LCD panel that is not covered can be easily damaged b, The hinges of the laptop would wear significally faster, because of the extreme weight

    • What is really your concern??? This is DIY.. Not OEM.. 😂 😂 😂

    • @sjm4306 Except the Flat earths most should really be taking there lithium and not on ILaward.

    • @Leicht Sinn What you say is completely true... But also, hinges of ThinkPads with magnesium housing are really durable (I'm a laptop repair technician in Hungary), they nearly never break. But they also would not handle 3x the weight of the original screen. Your english is fine ;)

    • @Dominik thanks :)

    • Lenovo already makes a portable external screen

  • your channel is so inspiring :D Thank you for all your work

  • Improvement ideas: 1 Thinner power solution: 1.1 Connect in parallel phone batteries 1.2 Connect them to a USB power module 1.3 3D-print them a housing and place them all in a housing 2. Thinner, smaller and stronger hinges: 3D-print a hinge with a smaller circular axis, and longer arms. Benefits: • They can be thinner, • They can support the weight of the plate over a bigger surface area (for better weight pressure distribution) • If casting them from some metal: use liquid metal to connect them to the big aluminium plate (for heat transfer - combine with connecting the screen to the plate, too) 3. Use a cog-wheel/spring-based hinges Advantages: • They can support more weight (for heavier screens and extra and for being on the go - to survive quick movements that push the screen back) • They could be adjusted to be toggleably-locked, for more viewing angles, and keeping the angle you want (like in folable phones nowadays) 4. Combine 3 additional screens in total: Take advantage of the other 3 sides of the laptop's screen, and add 2 additional screens, for a total of 3 additional monitors 5. Even more screens (more difficult to execute, need to be stackable): Find a way to stack more screens such that they're foldable and lock them all in place, to a rectangle shape, for a total bigger screen size (like it's done for TVs) - might need extra hardware

  • for the hinge, I think GoPro adhesive mount may work, it could erase easily by wd-40. Recommend to someone who has no 3d printer and no ability to diy a wood parts

  • I'm not an electrician but I'm going to try this! I have two old laptops sitting on my shelf eating dust, couldn't sell it because of its value, but didn't want to throw it away because they caused me a month of wages each when I bought them.

  • Great build! I would love to see your take on a DIY motion-simulator seat for flying/driving games! How would get a little tilt/roll in an ordinary chair for minimal $$

  • Amazing! I have too many dead laptops to remove the panel, and will try to do this ♥ ️

  • you should make a sliding screen version that way the monitor face is protected edit: use the same idea as before but but make your own laptop a desktop replacement you can do it i know it

  • 9:14 this is genuinely useful in coronatimes, to meet with clients and show them projects, whilst keeping 2m social distance

  • Excellent DIY ! Useful and effective

  • Friendly tip: Looking at your 3D printer (when you printed the hinges) I can tell you that its not calibrated properly. I would say the hotend is too hot for the filament you are using. Since it looked bubbly on the heatbed.

  • Smart fella, good ideas, fascinating implementation. Keep going the good job!
