AMH A409U UHD 4K 40" LED Monitor 3840X2160 60Hz Mastar One Chip Solution DP port 1.2, HDMI 2.0 & HDMI 1a.4, AUDIO port + Remote control

outstanding monitor for your desktop PC, I gave it a 4 stars because it is still new to me....

Works really well as an all around Display for a PC. And it works for My Xbox One and an Up-scaling Sony Blu-Ray Player. This particular one, as the name implied, had no Dead Pixels. It's OSD had been set to be in English. And all connection ports were set to their highest, HDMI and Display Port. The Minimal Remote is useful. It means you don't have to reach behind the Display's edge to change inputs, or access the menu. It can also change the volume (the plus and minus on the ring) and cycle through the available Crosshairs (the down arrow - when not in the menu), and it can cycle through the Zoom Modes (the up arrow - when not in the menu, or the Zoom button).Overall this is the perfect size for a 4K display. The Pixels Per Inch is about the same as most 27" QHD (2560x1440) LCD Monitors. It's just a lot bigger screen. The MVA panel is a nice compromise. It's not as slow as an IPS would be and it has better blacks. But the colors, and viewing angles, are far superior to a TN panel. Currently we don't have any connectivity standards capable of exceeding 60Hz @ 4K. So don't expect to Overclock it. But this display will do 4K@60Hz@4:4:4 with the zoom mode set to "Point to Point". Mine switches down to 4:2:0 sub-sampling when I set the zoom mode to "Wide". Input lag isn't really super low but it's completely livable for lots of games.Now if I get picky I can find 3 faults to this display. 1. It has a 1/8" "shadow" around the outside of the display. It's really small and doesn't bother me at all. 2. Mine has some scratches on the lower left corner of the screen. But I can't see them at all when the display is on. And 3, the headphone out port has a definite hum, when no sound is playing. Now I've ordered a Mini TOSLINK to 3.5mm optical cable to see if I can connect the Display to a DAC / Headphone Amp and eliminate the hum. So, for me, that one issue is all that keeps me from being completely satisfied. Meaning this Display isn't perfect but it's really close!

I've had 2 of these in dual monitor setup for over a year. I am completely in love with these monitors and this setup! I don't see myself replacing these for a very long time.
