Review on AOC U2790VQ – 4K Frameless DisplayPort Monitor with Tilt Adjustment, Wall Mount, Blue Light Filter by Scott Stackiin

I'm sure some people have problems or questions about the different ports. As the description says, there is a DisplayPort, HDMI 2.0 and HDMI 1.4. After some questions and research I would say that you really need two HDMI ports or not. The typical connector used is HDMI 1.4 and the supplied standard HDMI cable is 1.4. If you are planning to use 2.0 I was told that you must use the correct (high speed) cable or it could cause problems. For those trying to connect an HDMI to DisplayPort cable (on opposite ends), it only works from HDMI 2.0 to DisplayPort. However, you will run into a refresh rate issue (your settings tell you your display is only 30Hz). On a typical primary or primary HDMI 1.4 DisplayPort setup, the frequency is 60Hz (or a little less, but close). The color is amazing but I recommend using the night light screen settings for your eyes.
