After reading the reviews I thought a little about buying this video monitor. However, when I unpacked it and set it up on my Rpi 3B+, I was pleasantly surprised at the quality of the screen. I didn't have to go into the Rasbian OS configuration to change the screen image size as it would ask me for the screen image size during my Rasbian OS setup and fix it to full screen on the next boot.

Hard to believe this screen performs so well for the price. I had a problem with the first screen sent, but the replacement is fantastic, the built-in speakers are also not suitable for their size, thanks for the after-sales service and the reliability of the product.

I bought this monitor to use with a laptop via HDMI. It exceeded my expectations. First, the brightness is fantastic. So much so that I have to scale it down a bit. Also, it comes with just about every cable you'll ever need, which I really appreciate. So yes, for the price you're getting a fantastic little monitor to take with you on the go. I'm very happy with it and recommend you just jump in and buy it at this price point.

Very good quality, am using it as my main monitor right now because over 60Hz is not what I need. Very crisp, few buttons and very intuitive. Need to swap HDMI connectors? it will do this automatically when it stops sending the signal. This is a great little monitor.

Includes HDMI input, speakers, power distribution for RPi. The perfect add-on for Linux. Use mine for amateur radio applications.

I use it on racetracks. Connect my phone to it and broadcast the race. 5V is great for this with my small power supply. Thanks for attention.

The element did not turn on all the time. Usually 3-5 attempts, sometimes more. Switch off once alone, during use, after three hours and again less. A typical error was "no input" or something similar, although the HDMI cable never changed position and the device worked 95% overall. A failure rate of 5% is unacceptable for this type of item, especially if it affects the starting point of use and goes offline for no reason.

Bought as a second monitor for on the go. Requires HDMI as both USB ports are used for keyboard/mouse. Plugged it in and it worked right away. Very happy with this purchase.

When using the headphone jack, the volume is very weak even at 100%. I haven't had this problem with other monitors. Hooked it up to a tiny amp and now it's loud, although that's another thing that uses power.

In general there are no complaints. Nice and clear picture. Nice bright screen. No connection, management or setup issues. The price is a little high, so I'm deducting a star. 2/3 the price of a 43 inch 4k TV is a bit overpriced in my opinion. But for a small area I need to place it and a high resolution at close range. This is the winner. Recommended.

it is small and light enough to travel with. Overall it's very easy to set up. I wish there was a regular USB port and the ability to use the main laptop as a power source instead of a separate power cord.

Easy to store and install. Works right out of the box. It also has a 1/4" 20 tripod mount for those who want to use it with a tripod or 1/4" 20 screw mount.

The stunning small screen would have gotten 5 stars, but the speakers keep making high pitched sounds so I removed it as I only use headphones anyway.

It powers my Raspberry Pi 400 perfectly, the picture is clear, sharp and very responsive. Its light weight, included stand and all necessary cables make it easy to take the Pi 400 with you to different meetings if needed. Not much harder to set up than a laptop, not much heavier.

I think this is a great external display for Pi 4 but not perfect. The quality is good, but the connector panel on the right leaves a lot to be desired.

I mainly use this for my Nintendo Switch which works flawlessly. However, it often goes black when used with my phone for screen mirroring. I think the HDMI is wired to draw more power than it can provide and is draining the display circuitry causing a reboot. For the 12V supply this is not a problem, which confirms my theory.
