12 inch monitor

Works PERFECTLY for my retro computing needs! Picture quality is far better than I was expecting. Also, I now grab this little guy whenever I need to test a PC that's not attackhed to a monitor, so convenient and light and compact. Perfect for my needs.

Works when you get and that is the most basic requirement unlike the HTNZER unit that I just sent back because the BNC connecter did NOT work.

I’ve completely rewritten my review after using this monitor for a while.I originally faulted the little 8 inch monitor for being somewhat blurry and having weird HDMI resolutions, but after using for quite a lot of different things, I actually see this as a godsend for so many odd-jobs. Needing a bigger resolution without having to create custom ones is so useful for graphs and stuff. Often time when I’m using remote desktop sessions, I’ll have this little Eyoyo monitor set aside with OBS capturing cropped-readouts and other stuff that couldn’t all fit on the same screen. All while running a fullscreen remote desktop session on my main monitor.The USB port on the back can supply its own power so it can power things like VGA//DisplayPort-converters. HDMI headphone-jack-splitters, etc. Even better, the power requirements of the monitor itself are actually quite lenient and I’ve run mine off of a single 9V alkaline battery when I needed a probe camera to inspect the internals of a car radio.With that said, it can be quite blurry if the sharpening-slider is set to 0. Always run this monitor with sharpening!If there's one thing I wish it had? It needs a headphone jack. HDMI audio splitters are clunky and annoying to transport. A headphone jack would be great

Seems clear, everything I've tested works, runs off of 12V easily.

I purchased this monitor once and it stopped working so I ended up buying the same monitor only for that monitor to stop working within a year & a half. Apparently these monitors are built to last no more than 2 years. Luckily I purchased the 4 year extended warranty with Asurion but will now have to submit a claim and hopefully I'll get my money back to order a better product. On the first monitor, what seemed to stop working was the power cord so maybe it's a faulty power cord & not the monitor itself.

Over the last two years, I have purchased three of these Eyoyo monitors. I use them with my security camera system so I can have visual access to my camera outputs in the three rooms in my house where I spend most of my time.They are excellent monitors. They produce very sharp images with vibrant colors. Furthermore, these monitors have all the input and output capabilities and features of a large, pricey HDTV at a very economical price. I very much recommend them if you are looking for a small, handy, quality monitor at an inexpensive price point.I am a big believer in Eyoyo products. Not only are they high quality but, also, they have excellent customer service. I wish all vendors would be as nice. They are responsive, supportive and dependable. They have helped me immensely with the setup of my products and I really appreciate it.

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.

This a perfect small monitor to use with CCTV system. In my home I have such a system but only want something small to view. This is ideal. The picture is clear and the color is perfect. Very easy to set up. Comes with all of the cables and a sturdy base.
