LCD Monitor Problems non-native rez prob

I'm having problems with my new monitor, an Iiyama E431S which has a native
resolution of 1280x1024. When in non-native resolutions e.g 1024x768,
800x600 the text looks terrible(corrupt looking) and graphics look
pixelated.

I understand that LCDs don't like to be in resolutions besides their
native, but I didn't expect this much of a shift in quality. Basically the
other resolutions are unusable.

I think the problem may be that the monitor is not doing the 'smoothing'
most recent LCDs do to fix non-native resolution problems.

Has anyone had experience with the above problem, is it fixable via
software or could it be a hardware problem?
I have the latest monitor/graphics card drivers and I've tried both
analogue and DVI connections.

Thank you
 
Have you tried installing newe video drivers? What video card? And is it VGA or
DVI connection.

Hi Yanqui,
I mentioned that I've tried both DVI and analogue connections. The graphics
card is a Sapphire 9800 Pro. I'm using the latest drivers (catalyst 4.9)
and tried older drivers just to make sure.

I've just now uninstalled the Video Driver (Catalyst 4.9) and the smoothing
in non-native resolutions works fine! Its only after I install any kind of
ATI driver (catalyst old and new, Omega) that it has problems in non-native
resolutions. What do I do?!

Thanks
 
LCD's are NOT designed to be used in non-Native mode. As you see.

Yes I know. But newer models are able to smooth out non-native resolutions
to an acceptable level. As does mine when ATI drivers are not installed.

See if there's any adjustments possible in the driver.

Try a different driver.

Try a different video card.

Try a different monitor.

I've had a look and can't find anything relevant, but I'll keep looking.

I'm tried the monitor with 2 other systems. One with another ATI card and
one with Geforce card. Smoothing works with the Gefore and fails to work
with the ATI

In my mind, it's yet another example of why to avoid ATI
cards. Great hardware isn't worth a few 3DMark points if it
doesn't have the software to back it up.

Send ATI a compete description of the environment and hope
they get it fixed some day.

Thanks for the reply Kony.
Its obviously a problem with the driver. I'll email ATI and hopefully they
can give me a solution.
You're right, since googling this problem, I've seen countless complaints
about ATI software. The strange and annoying thing is that I've not come
across anyone with the same dilemma as myself.
 
I just purchased a Sony SDM-HS74P and have similar problems with non-native
resolution. Video is a Radeon 9000 and installed Catalyst 4.9. Guess I'll
need a new vidoe card.

Although I'm not happy you're facing the problem with the card, its good to
know I'm not the only one!
I've done so many google and groups searchs and no-one else seems to have
the same problem.

I'm thinking of swapping the card for an Nvidia version. Does anyone know
if there is a comparable card from Nvidia to the 9800 Pro.

I haven't been keeping up with benchmarks of cards as much
as I used to, but ballpark would be an FX5900 or 6600...
IIRC, the former is slower at DX but faster at OGL, but the
latter is not yet(?) out in AGP format. IIRC, anything
lower than a FX5900 cuts the memory bus width in half so an
FX5900XT would be the lowest comparable card... nVidia took
opposite approach to ATI, IIRC, "XT" means slower than same
number without the XT tacked onto the end.

Then again, seems like there are a few Radeon 9800 Pro cards
out now that also have the halved (128 bit) memory bus too.

Since 6600 is't available as an AGP version yet AFAIK,
FX5900 is the closest. nVidia seemed to be dumping the FX
cores at low prices so the non-XT version might be nearly
same price as the XT version right about now, making it the
better buy but they're quite large cards, if your case isn't
really deep you might need a shoehorn to get it to fit...
Google should be able to dig up pics.
