My U2713HM display fuzzy and blurry if I use it in full resolution 2560x1440 60Hz. But in low res its fine 1080p.
I tried factory reset, switch HDMI (HDMI work fine but only display 1080p,)
Uninstall graphics cards and clean install no luck, using dual link dvi cable , it was working fine for last couple of years, is it graphics card or monitor.
When i cold start computer it can display full resolution for couple of minute then its start flickering getting blurry.
Click my name and private message me the monitor service tag number and/or 20 digit serial number as well as your registered name, email address, and phone number.
