Review on Dell 27 Inch QHD 165Hz Compatible 2560X1440P Monitor with Tilt Adjustment, Anti-Glare Coating, GG42, HD, LED, IPS, HDMI by Jay Diaz

There are no visible dead pixels and a very good picture. I see some others talking about a little bit of back flickering, but when you're in the center of the monitor it becomes somewhat consistent. From my last monitor to this one, I didn't really notice it in everyday activities or even games I played including night scenes. I'm still waiting for my new laptop due to backorders, so I'm using this now on my Windows 7 PC. Windows 7 drivers are not supported. I was able to manually install the Win 8/10 driver to at least get the full 2560x1440 resolution, but it got stuck at a 60Hz refresh rate. I used the custom resolution utility to tweak a few things and add a 120hz profile which worked. , because my old graphics card supports this refresh rate and resolution. However, I had to use a DP cable as the HDMI cable didn't cut it. As soon as I get my new laptop I will be able to run it at full 165Hz.
