View Full Version : LCD - blurry look (at its native reso).

15-03-2013, 10:10 AM
Hi, I have a Dell Ultrasharp running at 1920x1200 its native and see this blurry effect, I have already downloaded the latest drivers from ATI. It's a PCIe 4800 series. Running Win 7 x64. See attached. Any suggestions? Thanks. I think I got this after some Windows Updates but cannot recall which one, I updated a few of them. When I switch to other apps and back it may fix it or if I minimise all and back again.

Are you sure it shouldn't be 1920x1080?

Does turning ClearType on/off help?

Nah ... its a 1200 reso monitor.

Will report back on the font after a while ..

If it's showing up on your screenshot then it can't be the monitor. Must be Windows\Graphics card.

A monitor problem would not show up on a screenshot, only a photo taken of the monitor with a camera

Turning off ClearType the fonts look different ... didn't use it long enough to notice if the blur came back.

I uninstalled ATI Catalyst suite and rebooted, saw it just before again. Will install a older version and see what happens.

I may system restore my image back 2.5yrs :lol:

The restore point couldn't finish, some error. I have uninstalled ATI Catalyst and removed the video driver now using the 2011 Windows driver, same reso at 1200 but still get the blur. Was working properly a couple of days ago ... Doesn't happen with VGA outlet but don't wanna use that.

Might be the cable youre using then

Will try that thanks.
I think I had this issue back a few yrs ago .. too. So I used VGA for some months :lol: with a $1000 monitor at a reduced reso due to my video card.

If it looks fine there's nothing wrong with using the analogue input, just make sure you have a decent cable or you may get ghosting etc.

I think VGA, the ATI HD 4830 is usable but it's not that great, the reso becomes something 1680x1050. The higher reso is not visible unless I go with DVI.

I just tried another DVI cable here, I got the same blur.

Saw the other mode, so went from 59Hz to 60 to see if it makes any diff ...

Edit - that didn't help. When I press the F5 in the web browser, some of the text goes blurry then it corrects itself once refresh finishes...

I might have found the issue:

Due to a optional windows "platform update" windows update.

Restore point didn't work, so I reloaded the image file. All fine and after like ~2GB of updates :lol: until some of the later updates.
