Help me minimize "moire"

[ccoltas]

Is there any Matrox utility or tweak that can help minimize "moire" patterns on a monitor?

I have a 19" monitor that has some residual moire that makes the text looks a bit grainy or fuzzy at any resolution above 1024 x 768. I notice it at 1280 x 1024, which is the recommended resolution for this monitor. I want to use it at 1280 x 1024 and higher, period. I have been unable to eliminate the problem by adjusting the OSD controls of the monitor. I was wondering if there is anything that can be done on the videocard side of things to help me fine-tune my monitor performance?

thanks for any info

P.S. Please don't tell me to return it. I have already tried that and i'm waiting for a replacement. Should the replacement have the same problem, I would like to at least try to get rid of the "moire" using other means.

What kind of monitor, try the developers homepage for help.

Try some different resolutions. Some are usually better than others.

Nothing on Samsung home page.

I want to use the 19" monitor at a desktop resolution of 1280 x 1024, which is what most people use for a 19". Changing the resolution is not an option for me. If I cannot get the quality of image I want at the resolution i want to use, then its pointless. Besides, the 19" Samsung 900 IFT monitor has "moire" to some degree at all resolutions above 1024 x 768. Using a 19" at 1024 x 768 is useless. Might as well be using a 17" monitor.

The monitor was made to be used at a recommended resolution of 1280 x 1024 and that is where I see moire. I can minimize it, but I cannot eliminate it.

If the replacement monitor I get still hs moire, I want the service technician to adjust the focus as a last resort.

any ideas about tweaking?

With my sony 19" i can change the moire with the osd, but you said you couldnt do that, you might want to try to change the refresh rate though. or get the latest monitor profile or drivers. or get a 24" TFT , just saw one on sale for only 15000DM (~7000$) , its from samsung too

Download the Resolution Manager somewhere from this site and add a resolution of 1400x1050.

I've heard from many 19" owners that they stuck to that resolution immediately

Perhaps it can also help with the moire problem.
Besides, I wonder what the guy (or gal?) that "invented" the 1280x1024 resolution had in mind: it isn't even close to a 4:3 aspect ration! 1400x1050 is, so it won't distort the image on your screen.

There are vertical and horizontal moire controls on the monitor. (there's also v and h focus controls) I can minimize the overall moire pattern, but I'm left with randomly spaced areas of vertical lines which intersect the text, making text look grainy, blurry. It is mostly seen only on the sides of the screen, but hey, there's still lots of text there and its annoying! It gives me a headache.

thanks for any help

24" TFT for $7000? Yeah, I dream of that type of thing. A 20" or larger TFT will be my next monitor in 6 years from now! Hopefully less than $1500 CAN by then!

To minimize moire you must customize the resolution so that it fills the entire screen. Do not use the moire utility in the OSD of the monitor since that causes the text to appear fuzzy.

you might also want to try 1280x960 wich i like better because i dont sit right in front of the monitor, and the picture seems sharper than in 1152x864 and 1280x1024 both, but i have another monitor (which i cannot really recommend )

[Wombat]

1280x1024 is the only common non-4:3 ratio out there. Try 1280x960.

And I don't like Samsung's anyway. My g/f has the 700ift, and it's not so good.

[ccoltas]

Pretty sure I tried all those resolutions. I may have spent the most of my time with 1280 x 1024 but i'll give the others a try, particularly 1280 x 960.

thanks

You can also try playing around with your refresh rate sometimes it takes a long time to find the best setting just keep trying.

From my experiments, moire seems to be dependent on the video card, in this case G400.
Example, if i swap my G400 to a ATI rage pro running at the same resolution(1600x1200), there's a lot less moire when using the ATI card.

Regards.

If your monitor support BNC connectors, you may want to try getting a DSub -> BNC cable. I got this recomendation when trying to solve the problem on a nokia monitor(replaced twice, didn't help) I never had time to try it, but you may want to try.

My video-card? I was told by many that "moire" is much more the fault of the monitor than the video card. Although my Matrox G400 has been doing some really crazy things lately! Like one day I turned on my PC and it was all-white! I hooked up another monitor and the video was squashed and out of sync! This doesn't sound too good. What is the warranty on a Matrox G400 max? I bought my card in Jan of 2000.

Its possible that the really sharp video quality of the G400 max brings out the flaws in a monitor more.

I just bought an AGP ATI All-in-Wonder Pro for $50.00 CAN for my Dads PC to replace his old 2MB trident chipped PCI video card. Perhaps I'll try the 19" monitor on that PC and see if there is a difference. It will certainly give me an idea anyways.

What about those adjustments in the settings for the matrox card? Porch lines, sunc and all that crazy stuff?
