I am not so sure what a 4K monitor would see as the benefit in a 9" diagonal screen, but the current 1024 x 768 is fine with a good sharp view and I have had no clear evidence of any issue with the flickering of the screen described by some with the use of HDMI linkage. I used my own HDMI cable and maybe the one I placed aside as supplied is rather of a poorer quality or maybe the people with such units experienced an issue not so universal.
For the cost the monitor provides crisp color and brightness and contrast. The remote is useful where the light monitor might be tipped over due to its lower edge controls, but a cautious user can adjust these from below if holding the monitor. The user is not likely to get much of a view of any screen contents at more than 4-5 feet so that distance is far from a consideration in reaching the monitor while it is in use.
I have had only maybe 5 hours of use, if that, but I see no problems thus far. I hope not to need to update this review.

There's a Trick to Get it to Work
This item doesn't work. I received it, plugged it in, and it won't display a signal for anything that I plug into it. The little manual doesn't seem to match the product, since the manual gives a different description than the actual device. This wouldn't be a problem, since it appears to have basic controls. However, it just doesn't work.The manual has no telephone number, or any contact information. It simply came with a little card which basically says that if you have problems, you must contact the seller, via Amazon support, and wait up to two business days. I haven't contacted them yet, but I'm already very disappointed. I just paid over $100 for an item that doesn't work, and I wasn't even given a phone number. So by default, that already spells "bad support".My feeling is that if you're going to sell a product, and provide no phone number for technical support, then that item ought to be so good that no one will ever need technical support. That's certainly not the case here.I'll contact the seller via Amazon. However, I'm already irritated that I bought an expensive device that simply doesn't work. No matter what I do, it simply displays a blue screen which says "no signal". This is independent of any device that I plug into it, or any setting I try. Buy at your own risk.%%%%% UpdateI contacted the seller and they were relatively quick to respond to my issue. Apparently, there's a little trick that you have to do in order to get this monitor to work.First of all, if you run into the same issue that I ran into, you have to make sure that a signal is going to the monitor first -- before you plug it in. Once you have a signal going to the monitor, plug in the monitor and then press the power button. Once the power indicator turns from red to blue, press the button, which is just left of the power button, until you switch to the correct input. Then you have to play with the buttons until you get to the volume. Once you start to turn up the volume, the picture should emerge.I turned off the monitor, and turned it on again. I didn't have to go through all of the above steps after turning it back on. I don't yet know whether or not this is a permanent fix, but at least I know how to get it to work.I'm glad the seller responded to my message in less than 24 hours, and that they gave me a solution so that I could get this monitor to work. The picture looks wonderful. I'll give this review two more stars because it appears be working well now. It would be helpful if this information was in the user's guide, front and center, in bold on the front page. But instead, like I said, the instructions have no mention of this trick. I had to contact the seller, through Amazon, in order to get it to work. The seller, however, was able to give me a solution, and now it looks great. They provided the attached picture along with their response.

- Reviewed in the United States on March 11, 2023Style: 8 inch 1024x768Verified Purchase
I bought this for an old retro computer, as the 1024x768 claimed resolution is exactly 4 times the screen resolution of the computer which is 256x192 so it should scale perfectly to fill the whole screen. The screen is nice and sharp and displays the computer screen, but it has massive borders, implying that the screen is a lower or drastically different resolution than claimed. Note if the screen was 1024x768, then the game screen shown should be centered and full screen with no borders. Looking at my photos, If 4:3 and 1024x768, the 1024x768 and 800x600 should fill the entire screen, and the 1280x720 and 1920x1080 should have borders at the top and bottom of the screen which they do not. So from my testing, this is a physical 4:3 ratio screen, but the pixel resolution in that screen is actually 16:9; the internal panel states HW800 which to me could imply it is actually a 800 wide resolution, possibly 800x450. Also note that on VGA, the unit will scale any resolution you throw at it and scale it to full screen, implying the unit in VGA captures the screen, then scales to fill the whole screen regardless of what aspect ratio you set. In VGA I recorded a 4 to 6 FPS delay from the source to it outputting to the screen.
The 8" is not the resolution or aspect ratio stated.
