My new flatpanel seems fuzzy

[SemperFi]

Ok fuzzy isn't exactly a good word to describe it. Pictures and most everything is good and sharp it is the text. The text lines are sharp but overall the letter looks somewhat blurred. It is hard to describe.

I have the ATI all in wonder radeon and I just bought a Sony SDM-M81 LCD. The panel is capeable of digital input and the all in wonder has a digital output. The only thing is they didn't give me a digital to digital cable. I have one on order nobody seems to have it locally. :disgust: So I have to use the digital to vga adapter that ATI supplied then the cable that came with the panel has a digital connector on one end and vga connector on the other end. I was wondering if the card out digital then convert to vga then the cable converts it back to digital plug of the monitor, could this double conversion be causing this problem?

The panel is capable of 1280x1024. I have the resolution of the ati set at 1024x768 and have turned on the clear type option. and I have went through the book and adjusted the settings as described. I also set the ati to 1280x1024 and it seemed to make little difference.

I am probobly missing something stupid here.

thanks

Edit/ I should also mention this is my first flat screen maybe this is a normal characteristic of flat panel screen?

wait for the cable? dunno, was having a lil bit of a problem with this on my gf2 ulrta (albeit with my CRT) and clipped the filter things as per anands article (only applies to geforces) and helped me out a bit (at least I think it did, may be psychosomatic lol) tried the latest ati drivers? (ha) hope the cable fixes it.

Run it at its native resolution of 1280 x 1024. All LCD monitors are fixed resolution devices. LCD monitors use a matrix of cells so the pixels are in a fixed location and therefore define the native resolution of the monitor.

For example a typical 18? LCD monitor with a dot pitch of 0.2805mm and a horizontal viewable area of 359mm has a native resolution of 1280 in the horizontal direction. Math is simple, 359 divided by 0.2805 equals 1279.85 or 1280 if you account for the small rounding error. Same calculation can be made in the vertical direction.

What happens at resolutions other than the native resolution is that the electronics must scale the smaller image up to the maximum size of the matrix or cells. The scaling is relatively easy if you are dividing or multiplying by 2 (going from 1280 to 640 for example, the height and width of the pixels are halved) but difficult when scaling by a non-integer. When the scaling factor is not an integer its not possible to uniquely assign data to a singe pixel or cell. The mathematical rounding errors can create the fuzziness or clarity problems you see.

Thanks sharkss I was wondering about that. I really didn't want to do that because I just got everything sized the way I wanted it at 1024x768 and didn't want to do it again but if it will help I will do it.

Daishan I just checked ati's site and they do offer an upgrade I will also try that. Thanks

Although the Sony monitors are supposed to have advanced scaling or whatever - in fact most LCD monitors should have this (I have an N80 as well as a whole bunch of cheapo AOC LM-500's) they work considerably better at their native (max) resolution.

Unfortunately none of Sony's LCD monitors are the best in terms of performance - although the N80 did have some unique features which made it attractive to me - despite the fact that Sony monitors have the 'best' prices... However your monitor should work very crisply at the max resolution with a DVI input.
