So I've followed the steps in that guide, and flashed my card with a bios that I've modified.

It does appear I'm on the right track, as now the tearing/flickering is completely different then it was but
it does still happen.

Before it would tear / flicker horizontally along the very bottom of the screen. Now it tears/flickers vertically
about two inches in from each side of the screen.

I'm going to guess that I don't have the clock speed (for memory I think?) where it needs to be. Changing that
value and seeing a change in the problems "performance" leads me to believe I am at least zeroed in on what
needs to be tweaked.

In watching in the Catalyst Control Center, it is 100% happening when the
GPU and Memory clock speeds jump. Even opening up CCC will cause the spike
which results in the flicker on the second monitor every time.

I'm going to mess around with flashing the BIOS once or twice more (tweaking numbers)
to try to get it to stop. If I can't, then I'm just going to sell this card and buy
something else. It's a very annoying bug.

Can you set it to keep the clock speeds constant and see if the issue still happens?

I set ALL of the memory clock speeds to 1200 in Radeon BIOS editor and then booted to
thumb drive and flashed the card with the modified BIOS using atiflash.

I am now flicker free. I was ordering a new GPU before the day was over if I couldn't
get it to stop. Since I was getting close to the deadline for being able to send back
the display itself. Just glad to see it was actually the cards fault and that I could fix
it!

Sooo.....

I just finally got around to trying some in depth calibration on my two IPS displays.
Seems to be harder then I thought it would be. Any tips on how you guys do calibration?
I've gotten them "better", then what they were out of the box, but I feel they could be even
better. Colors are so much more vibrant with the changes I've made yesterday.

I really want to see what these screens can do. I'm still pleased with them though, two 24" IPS
AH-IPS monitors for less than $300 is a steal in my book.

Actually let me know what you did. I do have an IPS monitor but I never messed with calibrations. Just let it do its thing. It looks way better then my old monitor and I have had this one for a few years now with no issues.

What I've done already is to google my monitor make and model and found some suggested settings.

Those were "ok", but I made some further tweaking to things like the color temperatures, brightness,
contracts and the like. Minor tweaks really, those suggested settings got me in a fairly good ballpark.

I do think this display can do better, but even if I had to leave it as is right now I'd be ok with it.

I know you can buy some expensive calibration hardware, that are not worth it for my uses. I think they cost in
the ball park of at least $200 and I'm sure can get much more expensive very quickly.

Software wise, there are some decent sites out there that have "test images" and guides to follow. Although I personally
feel those are more "fine tuning" steps then dialing in your display from the out of box settings.

I haven't bothered calibrating my screens at all because for me what was most important was the vastly improved viewing angle IPS gives vs TN.
