New video card - CRT ghosting??

[fendel]

I just upgraded from a GeForce2 MX 400 card to a GeForce 6200. My monitor is a Samsung 900NF aperture grille CRT. Now, for the first time, I'm seeing what I think is ghosting -- in high-contrast areas, like large black type on a white background, I'm seeing a faint shadow offset to the right a bit. For example, if I turn up my browser font size and look at the word "Web," I can see a very faint couple of marks to the right of the word that echo the right edge of the letter b. Plus, small text is a little messed up (reminds me of running the sharpen filter in Photoshop once too many times).

If I uninstall the Nvidia drivers and use the standard VGA driver, the ghosting disappears, but no way am I willing to run my 19" CRT at 800x600 and a 60hz refresh rate. Yow.

If I use the Nvidia drivers and dial my settings down to 800x600, the ghosting disappears.

If I run at my preferred settings of 1152x864 (or higher) and 85hz (or higher), the ghosting is there.

I don't know much about video, but I tried the take-a-stab-at-it things... tweaked all the monitor settings, ran through some stuff on Tweakguide.com, messed with the Forceware settings, disabled fast writes in BIOS, even turned my AGP speed down to 4x in BIOS (what the heck). Nothing is helping except for turning my settings down to Fisher-Price Strobe Light.

My monitor is in the same position it's always been in, same cable, no new sources of interference. Does this mean my new video card is a dud??

Sorry, I have no idea what you are talking about.
It does sounds like a software issue though.
Anyway, the bottom line is that, "CRT does not ghost, LCD does."

Try some different drivers. Check out the tweak sites for new beta drivers or older revision drivers. http://downloads.guru3d.com/download.php?id=10 I'd give 81.84 a try.

Edit: and it may very well be that your video card is bad.. If all drivers give the same problems at 1152x864, then return it for a different card or different brand.

ghosting only exist on LCDs

This sounds like true ghosting, rather than the motion blur on LCDs that's generally called ghosting. It's usually cause by some kind of electrical interference. Make sure the monitor VGA cable is sufficiently thick and attached securely on both ends, although it could be that the 6200 you got just has poor DACs.

I agree. What most people call "ghosting" on LCD's really isn't ghosting at all.

Try 75 Hz and 1280X960 to see if it's still there. You're using a sort of "tweener" resolution that sometimes makes CRT's act funny.

What brand 6200 did you buy? Some brands still use crappy 2d filters that makes text look not as sharp.

ghosting is the image leftover after image is gone, it's very noticeable on the 2005fpw.

The point we were trying to make though is that what you're describing is really "motion blur", and yes, that still shows up on many LCD's. "Ghosting" is really more correctly used to describe what the OP of this thread is talking about.

Hi all. Thanks for your replies.

This card is "ASUS N6200/TD/128 Geforce 6200 128MB 64-bit DDR AGP 4X/8X"...

Ghosting was still there at 75 Hz and 1280X960. (1152x864 is unusual, I know, but my old GeForce2 MX did fine with it...)

I'll download 81.84 and report back in a bit...

thanks,
fendel

Installed 81.84... no dice.

I put my old card back in there and it looks fine again, so I think the cable is OK.

I have a GeForce 5200 I got for our other computer-- I'll try that later and see what that looks like. (I guess if my old card and the 5200 both look good and the 6200 has ghosting, it's RMA time.)
