Review on Haorizi 12 Inch Color Security CCTV Monitor 800X600 4:3 Video And Audio TFT LCD Display Screen AV/VGA/HDMI/BNC USB Input With Dual Speakers… by Chris Hossain

Bought this display to use primarily for setting up Raspberry Pis. Picture quality is excellent, but it shows a resolution of 1200 x 799, resulting in what appears to be a single scan line spilling from the top of the display to the bottom of the display. I don't think it's very noticeable when using the GUI, but it's very annoying in console mode (text mode), which is where I'll be mainly using it. I'm not sure if it's an RPi or a monitor, but that doesn't happen with other large monitors I have. I've tried every monitor setting I can access and nothing seems to fix this. There's a submenu in settings that might have something, but it looks like it's disabled or unavailable. The manual that accompanies the device doesn't mention this submenu at all. If this cannot be resolved, you may need to return the device.
