Blurring LCD monitor screen

post #1 of 12
Thread Starter 
I have an LCD that's been getting an intermittent kind of blurring (monitor looks like of like a bunch of tiny ripples are vibrating across the screen) some times it's worse than others.
I can't find any kind of trigger for it and I''ve already tried unplugging and securing my VGA cable ends back in. I also ran the LCD conditioning feature to see if that would help, but it doesn't seem to stop on its own no matter how long I run it, and it doesn't really seem to help either.

I've been using this monitor for a while, and this only started recently.
Any ideas?

Have you tried using a digital output like DVI/HDMI?

This monitor has an HDMI input, but my PC has no HDMI output, and vice-versa for the DVI.
So VGA is the only option.

Maybe i dont understand correctly, but as mentioned before can you buy a HDMI/DVI cable that has and hdmi side that plugs into your monitor and the other end is dvi which plugs into your dvi output on the back of your pc case video card.

Try using a power extension lead, and try powering it from another power outlet smile.gif
I'm thinking it's getting interference from something thinking.gif

I had a monitor do this! And it was getting interference from my surge protector redface.gif

Well the GPU is fairly recent, so I don't think it would have problems with a 1600x900.

Hmm, I have the monitor and computer both plugged into the same power strip, I could try running the monitor to a different outlet . . . if I can find a clean extension cable. tongue.gif

I'd definitely give it a try smile.gif

Once I found it was just interference, I didn't care about it any more! biggrin.gif

Tried two different outlets, still got the blurring, so it seems unlikely that it's a power issue.

OP, have you verified that the proper resolution and refresh rate are being set by your video adapter that match your monitor's native resolution and refresh rate?

This might not be the same thing, but it sounds exactly like what I notice on my smaller 19" 1366x768 native res monitor when I accidentally set the resolution on my video card to 1360x768--it looks like vertical lines of blurriness rolling across segments of the screen. But the odd thing is you said you're running 1600x900. Are you sure that's the monitor's native resolution (or rather, native aspect ratio)?
