Question 1

How do I get 144hz and 4K? I can't seem to be able to do both.

Accepted Answer

First of all you need to have a GPU capable of 144FPS @4K. If you can check that one off, you need to connect your pc with a Display Port cable that supports those frame rates at that resolution. If not the cable will bottleneck the data transfer from pc to monitor. I'm using a cable that is capable of that and I get 144 FPS at 4K. There is also an option in the monitor menus where you can select to overclock it to 144. I believe when I first got the monitor it only got at 120 and then changing the setting it went to 144. Check the manual for instructions.

Question 2

Is this monitor G-Sync compatible?

Accepted Answer

Yes it is. I am using it with G-Sync with my RTX 4080 GPU. You do need to use the Display port in order to enable G-Sync, I don't think it works over HDMI.

Question 3

The screen panel is VA? Not IPS?? The same model on ACER showed IPS panel

Accepted Answer

This model (Acer Nitro XV322QK VBMIIPHZX) has a VA panel. There is another model (Nitro XV322QK KVBMIIPHUZX) that is IPS.

Question 4

What is the real contrast ratio?
