Hi everyone! I have recently encountered a problem with my LG 27UD58-B monitor. I have bought this monitor in December 2016 and have been using it ever since with no issues up until a few days ago when I've changed my computer and went to using the monitor on DisplayPort 1.4 rather than on HDMI which I have been using up until now. During the first day of using the monitor everything was great, image perfectly clear, fonts perfectly clear, but the next day, after starting the monitor, everything went blurry, and it's not just in Windows 10, but also in bios. Could the change from HDMI, 4k at 30 Hz to DP, 4k at 60 Hz have triggered something within the monitor, because at the moment, the image is blurry no matter if I connect the computer using a HDMI cable or a DisplayPort Cable.
I have tried different computer from my office with different graphic cards, different cables, even bought high quality HDMI and DP cables to see whether the issue could be cable related, but everything seems to point to the monitor being the culprit.
The computer that I've changed to is a Lenovo ThinkCentre 920q - https://www.lenovo.com/au/en/desktops-and-all-in-ones/thinkcentre/m-series-tiny/ThinkCentre-M920q/p/11TC1MTM92Q, but as stated above, I don't think it has any relevance.
Have you guys had any similar issues with LG 4k monitors? Any thoughts on the cause of the issue?
