TFT Fuzzy Image on Low Resolutions

[Akira]

Hi Guys,

I've recently had call to re-image a PC and installed latest vid drivers.

The problem I'm having is that when the res is lowered (1024 x 768 say) all items on the display become surrounded by a 'fuzzy' border.

If I increase the res to beyond 1024x768 it's okay.

I've not seen this before - anybody have any clues?

Thanks folks,

Akira.

TFTs have optimum resolution settings - set by the physical pixel spacing. If you operate it below that you may get the results you describe.

[Akira]

Cheers for that.

The monitor is a bog standard HP jobbie and has worked fine on lower res' until the re-image, so technically it is capable of doing so.

Thanks again Pete,

Akira.

Hmm - interesting! What happens if you put the old drivers back in?

[Akira]

Well, it was fuzzy with the ones that came down with the image so I downloaded the latest drivers from the hp site, installed and rebooted but the prob persists...

[peterb]

OK - I was just a bit confused when you said that it had worked OK at lower resolutions...

[Akira]

Hmmm, it's a doozy alright - as I mentioned about, never seen this prob before and I can't find any helpful info via the web either (except for Hexus of course ;-)).

Cheers again,

Akira.

Make sure that when the monitor kicks into a lower resolution that the refresh rate hasn't been knocked up from 60Hz. I've known that to cause clarity issues on some cheaper TFTs.

DVI or Dsub?
Using Dsub on some TFT's can cause this

yup, check it's native resolution and keep it at that.

If that doesn't work then check cable, pins, drivers.
