Hello, I just purchased a asus rog pg278qr from Amazon waredeals and in the description it only says that product got some scratch on the base and that's it. Description is true, the display is perfect and works flawlessly, no dead pixels or problems. When I try to go up to 165 hz using the osd the display resets, and when I try to apply the 165hz frequency the screen turns green and stays like that all the the time until I go back to 144hz. I used the dp cable that comes with display and another one I already had, same results. Is this a faulted unit? I do something wrong? Should I rma it? Will the 165hz a huge jump from 144? Thanks
