Scuzzy? Anyone? - TFT screens and blurred object edges
« on: September 05, 2003, 01:40:48 AM »
I have the Relysis TL765 17" TFT screen. I accept it's probably bottom end but I am looking for a reason/solution to a problem. It did not happen with my CRT screen although I also have a better video card now.

When a moving object (plane) passes by, the plane edges tend to blur - about 3-5 pixels - although if I, say, roll the aircraft, the terrain edges moving at around the same rate of ~3 secs screen edge to edge (shoreline etc) do not blur.

Here's the spec:
Model TL765
LCD Panel 17
Dot Pitch 0.297mm
Horizontal Frequency 24-60kHz
Vertical Frequency 56-75Hz
Cont-Ratio 400:1
Brightness 200cd/m2
Response Time 35ms
Safe STD FCC-B, CE, UL, TüV, TCO99, ISO 13406-2
Dimensions 368 x 353 x 204mm (H x W x D)

I am using a Geforce4 MX440 64Mb with directx 9.0b (happened with original 9 too) and driver version 43.45 (not the latest because the 45.23 don't work properly!). Rest is Athlon 1.4GHz, 512Mb DDR RAM, K7 Lite mobo, Win 98.

I have dxdiag data although it reports no probs.

Could all be in the setup - but being ignorant........

Appreciate any help especially from Scuzzy or anyone who has had (solved?) this problem.

Cheers

I don't have any TFT experience , but with that card you may want to try 30.82 or 41.09 drivers.  I have heard that you will get blurring/ghosting with most LCD's unless they are the newer ones with bout 16ms latency - yours is 35ms.

It is prolly due to your TFT beeing of an older type with 35ms... on 25 and 16ms i dont notice any of that..

hmm....

are your TFT and graphics card connected using DVI or VGA?....

If you use VGA and you can use DVI then try that.

Are you using the TFT at its native resolution? Its very important that you do, TFT's are always best at its native res. I suspect that the TFT is 1280*1024 but you try to run it at 1024*768 to get better fps.

What they said.  The blurring is caused by delays for the TFT's to shut down as fast as they need to.

As that MX card is basically a GF2, you really should roll back to the 30.82 drivers as they were the last drivers really optimized for that line of cards.  Stability is better as well.

Thanks for your comments guys.

I didn't know about the DVI thing I will look into it and I'll get the 30.82 drivers as well.

Native resolution is 1284 x 1204 which I select in Windows and AH Video. Is there anywhere else I should do that?

Thanks again

Nope, windows and AH should be enough.

On all TFT screens i have used, DVI really improves quality + you wont have to calibrate colours and all that. DVI makes the signal digital all the way from the card and to the panel. If the problem is "ghosting" it wont help tho cause that is caused mostly by high response times.

Good luck
