XL2720Z Serious Blurry @144hz Need Help
Posted: 12 Dec 2017, 19:53
Hello gentlemen, I am newbie to monitors and really need some help with my BenQ
So I bought this brand new XL2720Z last year and it has been working properly @144hz connecting via DVI DL to GTX1070. While the other day, like 6 Dec 2017, I woke up and noticed that my left hand side monitor is blurry, while the right hand side is okay.

You could see that the right hand side text is clear and it become worse and worse to the left. And when I look closer, there is a white line at the bottom of the left hand side.
At first I thought it was resolution setting problems, so I tried different combinations and found that the problem does not exist @60hz, and it goes blurrier when I raise the refresh rate.

I Googled a lot about the problem and found that many ASUS MG278Q have the same problem, see http://www.tomshardware.com/forum/id-35 ... nitor.html
I have also ruled out the following possible reasons:
1) Graphic cards. I forwarded my screenshot @144hz and view it on my phone, no blurry is found.
2) Nvidia drivers. I used display driver uninstaller to reinstall both newest and older driver versions. Problem still exist.
3) Win10 competability. I have dual boot system, win7 also blurs.
4) Cable not suitale. I was using DVI DL bundled with my monitor for a whole year and it worked properly @144hz. Many people suggest replacing cable would solve the problem. So I went to store and bought a DP cable, tested on-site, supporting 144hz no blur. Still, problem exist when back home.
5) Reset ALL in BenQ menu does not work.
6) ClearType adjustment not work.
I have also contacted BenQ customer service hotline, seems will go RMA in the end.
Yet I still want to fix it if it is not hardware problem. So does anybody know how or anyone have the same problem? Thanks
#And my XL2720z is running on firmware V5
