Hello all,


This is my first post here, so hopefully I'll provide enough info for you to solve my problem. Thanks in advance.


I was browsing the internet today. I had many tabs open and I think I overloaded my computer a bit (although I've had many more tabs than this open in the past, and nothing happened then.). Suddenly, my computer's monitor just black screened. After a while (maybe a minute), a  giant mouse pointer appeared, and then my desktop, with the chrome I had open. I quickly force stopped chrome with the task manager. AT the time, my resolution was set very low (everything looked big, like the windows and text) so I went into settings and changed my resolution to my native 1600 x 1200. But then, I noticed that my whole screen was blurry, ever so slightly, but enough to annoy me. Furthermore, everything looked a bit jumpy and my screen wasn't as fast/ clear as it used to be. I reset my display settings, although nothing happened. Also, when I looked at the display settings, they were clear and weren't blurry like the actual windows/desktop were. So I'm guessing it's not a problem with the monitor. I did some more digging and found out that in my display adapter settings, my screen's refresh rate was set to 64 hertz, even though my monitor is 60 hertz. There was no option to change this in the dropdown. And now that I think about it, I am getting some significant screen tearing that comes with having incorrect refresh rates. I couldn't figure out how to change my refresh rate, so I tried updating my drivers for my display and my display adapter (my monitor is connected in through DVI, through a displayport adapter, and into the computer with a displayport cable). The display driver updated, and the adapter driver did not, but neither improved my blurry screen problem. I have run out of ideas, so please help! Thank you in advance.

P.S I am typing this on the same computer and monitor, so it's definitely readable, just pretty blurry.

first, did you unplug your video cables and then plug them back in?  make sure they are seated good.

Welcome to Bleeping Computer.


Have you tried updating your video drivers?

see if the monitor is blurry connected to  a different computer at similar res...; if it is...monitor or cable you are using is bad, try a new cable and/or DVI/HDMI/VGA adapter, or whatever complimet you are using (VGA is the least best quality path to use).....


(KVM switches are also notorious for inducing some blur...)
