RE: PG278Q Hz Problem, need help please
You just don't seem to get it. It's not just the refresh rate that dictates how much bandwidth you need. It's a combination of bandwidth AND resolution.
A 640 x 480 resolution display at 400Hz uses less bandwidth than a 1920 x 1080 display at 60hz. I did your homework for you and found your laptop's specs. Here is a link. http://www.arp.com/medias/14482489.pdf It also specifically mentions your displayport's version. It is 1.1a. It is NOT 1.2, which is MANDATORY for running a 1440p at 144hz. Your displayport is not modern/fast enough to run your PG278Q at its native 2560x1440 @ 144hz. Your laptop is absolutely not capable of running this monitor at 1440p 144hz. Sorry. Get something newer to drive the monitor. |
