Here's the problem. At 75hz refresh, 1280x1024 resolution, on the
right side of my monitor, you can see the picture seeming to "bounce."
It is more noticable against lighter colors. In the menu for Battlefield
1942, it is almost halfway across the screen, and is very noticable.
Initially, I thought it might be the monitor. I have since tried
connecting the monitor to a different PC, and had no problems. I have
not yet dragged a different monitor over to connect to my PC (I hooked
the existing to a laptop)

Presuming it works out that my card is beginning to have problems, what
would be a good low-cost substition for a 9700Pro? I do not want to
spend a lot of money at this time, as I am planning to wait until next
fall, at which time I am going to do a complete system replacement.

I did replace some time ago the stock cooler on the card with a VGA
Silencer (rev3), which does seem to be working OK (no weird artifacts
when playing games, so I'm presuming the card isn't overheating)
I have been running my monitor at 75hz at 1280x1024 for many months
now, with no problems. It seems by taking the refresh up to the max at
this resolution (85hz), that the problem (at least in Win) goes away.
I also just did some testing, at 60hz, there is no "bouncing", at 70
and 75hz, it is there (worse at 70 than 75), and at 85hz, if it is there,
I can't see it.

Any ideas? If I replace the vid card, I would like to stick with a
built-by-ATI, rather than another brand.

Hi,

I assume your monitor is connected to the analogue output connector and not
the DVI connector, If so i have the same problem. (I think it was a common
noise related problem on early 9700 cards.)

The solutions as far as i know are.
Use different refresh rate if possible.
If your monitor supports digital input - use it. If not your card may have
been supplied with DV to analogue adapter, using the DV output with this
type of adapter should eliminate the problem.

Regards
IH

It sounds like a monitor problem. Why not run the monitor at 85 hz. I have
a 19 inch monitor and the maximum refresh rate of my monitor for the
resolution you use is 85 hz. So that's where I run it and all is fine and
has been for a couple of years.

Run at 85 Hz, then. Anything less will cause flicker and eye fatigue (esp.
in the dark).

Well, did some quick testing this evening, to try to narrow down the
problem.

I tried hooking the monitor up through the DVI->VGA adapter, which gave
no change, still get the "bouncies" on the screen, especially at lower
refreshs.

Then I tried hooking up a cheap, crummy, 15" LCD I've got (LCD doesn't
have DVI, what do you expect for under $200?) This worked flawlessy (no
bouncies, even in game) However, there are two problems with this LCD.
First, it only supports up to a 1024x768 resolution, far to low for my
tastes. Second, the response time sucks. I can actually leave a trail
of mouse pointers, without having mouse trails turned on.

Tomorrow night I'm going for the all-or nothing test. Swapping my
9700Pro for my wifes 8500, and seeing if the problem follows the card.
If so, then I at least will know for sure where the problem lies, and
what to do to resolve it. Either buy a nice LCD, or eBay for a used
9700Pro. Personally, as I am planning to put a completely new system
together late next year, I would rather get the LCD, as that will have a
longer life as far as my PC goes. Why spend $70-100 for a card that is
going to be replaced in 8-10 months, when I could spend (admitedly) more
on an LCD display that will last several years? I've had my CRT now for
going on to 4 years, and even with an LCD, would continue to use it as a
second display until it dies completely.

Tomorrow will tell. Followed by who has decent after X-Mas sales and
credit deals.....
