Cheap little monitor exceeded my expectations. The screen is very bright and crisp. It has a very high PPI - probably higher than your computer or laptop monitor which may cause complications if you're using it as a secondary monitor, as the interface scaling will appear different - so be aware of that. Because of the unusual aspect ratio of the monitor, you cannot properly downscale the resolution in windows Display Settings. However you can downscale it in the NVIDIA or GFORCE graphics settings from your video card. For example you can set a custom resolution of 960x360 to make everything appear twice as large on the monitor, at the expense of image quality obviously. There are robust display options to adjust the brightness and color levels to match your other monitors. It comes in a metal case with VESA mounting points, and comes with a little stand. The mini HDMI and USB C ports are on the side, so you may want to get right angle cables to connect to them depending on how you plan on using/mounting the monitor. The included cables are 1 meter long. There are 2 USB C ports, you can use one USB C for data and one for power. They are interchangeable. My computer doesn't support thunderbolt USB C monitors so I didn't test that. Measured with a USB Power meter, the monitor draws about .56A at full brightness, which is why it may not work properly on a regular USB 2.0 port which is limited to .5A output (the USB 2.0 standard). However I found the max brightness setting to be too bright for anything except using it in direct sunlight - at a brightness level appropriate for indoor use the power draw is about .25A ~ .4A. It does not have a DC barrel jack power input - only USB C. Windows 11 does not make it clear on how to set up this touch screen as a secondary monitor. By default the touch inputs from this monitor will be directed to your primary display. You have to go to "Control Panel" (NOT "SETTINGS") - Hardware and Sound - Tablet PC Settings. Then it lets you set which display the touchscreen gets coupled to. And the touch is good quality, capacitive so it responds well to finger touches and is pretty accurate, just like using a phone or ipad. I use TouchMouseTools utility (not free) to make the touch screen not move the mouse curser and makes it more usable as a secondary monitor and it works great. Overall a great bang for the buck. I use it mostly for flight sim control panels and it works great. Can't even find this type of monitor cheaper direct from China. The documentation is not very robust, so hopefully this review helps you out with some of the details.

I bought this portable touchscreen monitor to use as an extra screen for virtual stream deck +. At first, I was really frustrated because plugging it in with just the USB-C cable didn’t work — the monitor stayed black or said “no signal.” After some research, I found out that this can happen on desktops and laptops whose USB-C ports don’t support video output (known as DisplayPort Alt Mode). Many gaming desktops, budget laptops, or older computers have USB-C ports that are only for data transfer or charging, not for sending video. Here’s how to make it work: ✅ Use an HDMI cable (or DisplayPort, if your computer has it) to send the video signal to the monitor. ✅ Connect the included USB cable to your computer — this handles the touchscreen input and sometimes extra power. ✅ On Windows, open Control Panel > Tablet PC Settings and select the portable monitor as the touchscreen device. This ensures your touch gestures control the correct screen and not your main monitor by mistake. After setting it up this way, the monitor works perfectly — clear picture, smooth touch, and easy to carry around. Tip for other buyers: Double-check whether your computer’s USB-C port can actually carry video. If not, always use HDMI for the display and USB for the touch features. Overall, this monitor is an excellent value once you connect it properly and adjust the Windows settings. Highly recommend!

Ok. My first thought after getting this was to return it. I contacted "support" which was offered through Amazon which was a complete waste of time. Finally spent some time digging into the internet to figure out how to get things working. The video worked fine, but the touchscreen didn't work. The tiny user guide said that I had to connect a USB C AND the HDMI to get touch to work. I did that. None of my USB C ports on my docking station would make the full support USB C work (without connection HDMI also). I don't know if that's because my USB C ports are not the right version or if my cable just isn't adequate. I do know you must have the data quality cables and although I purchased those, I did buy them from Amazon, so don't know if my cables are actually capable of doing what they say they are. So. Did the two cable connect with HDMI and a USB C - USB A cable. That seemed to work with one quirky thing. I saw another reviewer mention this as well. Seems when you touch the screen it touches another display. So I could scroll on this little screen and it would scroll my main screen. That seems wrong. I did get one bit of helpful information. Go to Control Panel, Settings, Tablet Settings. Ok. But that didn't work either. When using Windows in Extended Display mode with more than one monitor. When you go to the Tablet set up screen, READ it completely. It said, "touch the screen". So I touched the monitor I wanted to be the touchscreen. That did not work. After another try I read the entire blub on the Microsoft screen. Seems you are not to touch the screen you want. Read the words. They appear on ONE monitor. If THAT IS the monitor you want to be the touchscreen, touch it. If not, follow the directions to get to the NEXT monitor screen. Eventually, you'll cycle to the one you wanted to be the touchscreen. THEN you TOUCH THAT ONE. And it worked. Would be nice if the user manual gave some clue as to how to set this up for Windows to work properly or had some support with FAQs. All I could find was, you need two cables. But that's not enough. The touchscreen will usually be wrong unless Windows miraculously put your monitors in the right order and associated the touchscreen properly, chances are that won't happen. So to the user who reviewed that the Windows touchscreen will control the wrong screen. That is true, until you go into the TABLET set up and change it. Then it works. So, now I'm kinda liking it. I set mine up in front of my keyboard with Winstep Nexus docks on it. I've created multiple docks on that app so this little 12" short monitor is like my launch pad for everything. Rather than having to use the windows start key and typing calc to start my calculator. Just touch it on that screen. Works quite well as a launcher. I did notice in the tiny user manual it says the product "shelf life" is 12 months. So I'm not sure how long this little guy will last being used every day. But his price was low enough that I'm willing to keep it. One other note. Since the cable ports are on the left side and that means now I have cables sticking out a few inches (because HDMI cables don't bend well), I ordered some 90 degree connectors for the HDMI. I couldn't find a 90 degree HDMI to mini HDMI. But did find plenty of HDMI/HDMI 90 degree connectors. So I'll just swap for a regular HDMI cable a short one that I ordered just for this and the 90 degree connector and I have lots of 90 degree USB C connectors (Thanks Amazon!) so that will tidy up my desk and not have those cables sticking out and taking up 2 - 3 inches of space. The monitor does come with a cheesy little stand. It does it's job. Not attractive, but allows me to angle the monitor. I might use a cell phone stand instead just because I have several of them that look better and allow for more positions.

Perfect for hooking up my Roku Channel Stick. You forgo the touch screen feature when you hook this lovely screen to either the Amazon firestick or Roku Channel Stick. all you need to do it just plug in the fire stick or roku channel stick in the on reg sized hdmi slot and power the monitor using just one usb c to usb a cable right into a power source like a power strip. that it . it works like a charm. very clear screen. all you need is wifi access and you're ready to go no computer necessary. 92 dollars very well spent as i got 15 dollars off the regular price. price to performance is through the roof on this baby. I could have purchased another 18.5 screen for a little more money or the even large 23.8 screen at 144 hrz but i decided to go small this time.

First, I want to say that this tertiary monitor was a game changer for my workflow, especially for Microsoft Teams. Having chats visible all day without disrupting my primary monitors significantly improved my productivity. I no longer miss messages, and it helped me stay more organized and on top of chats and meetings. Unfortunately, the positive experience did not last. Less than 60 days after unboxing, the monitor began flickering and flashing rainbow colors on the left side only. I tried swapping the USB-C connection to HDMI with external power, with no improvement. I also tested the monitor on three different devices using both USB-C and HDMI connections, and all resulted in the same flickering and rainbow issue. I reached out to Amazon and received little to no meaningful assistance. Not surprising as it was past 30 days. For a product costing over $100, I expected far better longevity and support. The failure feels comparable to low quality monitors from the early 2000s, which is extremely disappointing given how useful it initially was.

Its very cool and when it works its nice to have a monitor of this shape for certain things. 1. It does not work through just the power of at least my cell phone. S25 Ultra. It will flicker off and on and reboot itself over and over again. This means that in order to use it with a cell phone you will probably have to have it plugged into the cell phone and then another cable plugging it into the wall. Which to me negated the purpose of what I wanted to use it for the most which was just having a bigger touch screen for my phone while traveling. 2. On windows the touch screen will randomly start having issues. I don't think its a problem with this monitor just more windows 11 is REALLY bad with touch screens when they are not the main screen. So thats something else to take into consideration. If I could find a better way to disable the touch screen entirely that would be nice but I have not found that as of yet.

No complaints from me It is nice to have a larger work area or duplicate monitor for laptop pc or phone I have used it mostly for watching movies and tv shows from my S23 ultra I can basically turn my phone into a tablet with this It is great that it can charge my phone through the same cable as I am displaying from also I can power the screen from my phone alone but I dont recommend doing that for long periods as it will drain the battery I will definitely be taking this with me on vacations as I can almost eliminate the need for a laptop I have used it with my pc as well, but unfortunately my computer is a bit older and doesn't support usbc locally Overall I think this is a solid purchase
