This is the JAPANNEXT 28-inch 4K monitor JN-IPS2802UHDR. It has good color and image quality. I purchased it about a year ago and used it for testing purposes, so I haven't used it much. There is a scratch of about 5mm on the bottom left of the screen and a small scratch of about 2mm in the center right. It is noticeable because of the lighting for the photos, but it wasn't bothersome in practical use. It is a liquid crystal monitor equipped with a 28-inch IPS panel and supports 4K resolution (3840 x 2160). The 4x higher resolution than Full HD (1920x1080) achieves overwhelming high productivity. It supports a wide color gamut of sRGB 100% and displays images beautifully and vividly, making it ideal for photo editing and video viewing. The interface has two HDMI 2.0 ports and one DisplayPort 1.2 port. It supports "PBP (Picture by Picture)" which displays multiple inputs simultaneously. In PBP mode, two input images can be displayed side by side. It also supports "PIP (Picture in Picture)" which displays one of the two inputs in a sub-screen. It supports 100x100mm VESA mount, so it can be used with a separately sold monitor arm. It has built-in 2W x2 speakers.
