I can only guess that a combinational problem has somehow mislead you into eliminating the real culprit somewhere along the way... A few things still come to mind, and the others have mentioned some as well above:
1. Try swapping out the monitor cable. Has that been constant in all this? What port are you actually using on the video card? DVI?
2. Make sure, as I mentioned before, that the remnants of your prior video drivers are removed.
3. Get the latest display driver from ATI's web site.
When you say any app, what app specifically have you tried that does NOT use color-management?
No I have been swapping it with a different one every time I've tried something so it can't be that. I've checked for updates on the website and made sure I have the latest driver, rebooted after that too. There was only one thing installed for my old card and that gone, I've even checked in device manager and it's all saying the only one is the Radeon I bought.
Well I have tried it in photoshop, Corel paint shop, gimp and I know they are colour managed but it's still the same. I just downloaded the Irfanview and the banding is still there.
I know this must be getting VERY tedious for you, but one thing making it a bit more difficult to try to help is that you're not quite answering all questions...
I think it MUST be that the problem is somewhere downstream of the video card...
What kind of connections are you making at the video card and monitor? DVI? VGA? HDMI?
One other thing I thought you might check for: Any software starting up with the system or when you log in that does something to the display. It's a longshot but I suppose something could be writing strange calibrations to the display card.
A good free program for reviewing everything that's running (and disabling that which you don't want running) is Autoruns, which can be found here: http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx
Sorry I forgot to answer that. I'm using a VGA cable.
I've checked everything that runs on startup and it's only Corel photo downloader, avg, msn, welcome centre and then just presume it runs all the required things to power a computer.
Because of the need to generate and interpret analog levels, D to A to D conversion in VGA connections can yield more posterization under some conditions than DVI. I've seen that myself.
Does your monitor not have DVI capability?
We've been going on the assumption that this banding is new, but is it possible you've had it all along and just didn't notice?

FWIW, I got a malware alert from MS security essentials on that imageshack link:
Dag, I don't know if you use IE but if so, I can suggest ways to set it up that make it far less likely it will deliver malware to your system. I never allow ActiveX to run from sites on the wild internet - only from those in my Trusted Sites zone. This has the added side benefit of blocking many ads as well. Ads are usually what deliver malware.
Can you please, explain how you made the tests that ruled out your monitor. Did you make the tests with the other 3 monitors after you got the new video card? And using what kind of cables.
It could be hat you had previously bad video card and bad monitor combination. You also have to make sure that the other monitors you tried can display properly the test images without banding when used with other systems.
My monitor has VGA, HDMI, and Display port connectors, When connected with VGA to a video card, the display is total crap.
I've tried so many things I can't really remember, Noel walked me through most of it in this thread. Ive tried changing cables, trying other monitors, changing colour settings in colour management. Ive also tried changing the settings in the actual monitor. The monitors I use all display images perfectly on other computers, I borrowed my brothers and my parents an it works fine with their computers.
I use a VGA cable.
If you have any other ideas of things to try for the monitor please say and I'll tell you if I've tried them and if not try them. I don't think it's necessary to try everything again with the new card as I 99.9% eliminated that its the monitor before I bought it.
Well, you pretty much 100% eliminated the video card. What's left? Try a DVI monitor with a DVI cable, or reinstall Windows?
I have a monitor here on a system connected with VGA, and to be honest I don't see posterization in the images shown in this thread, except for in your photo.
Notably most of them are so dark I can't see much of anything. Is it possible your monitor is just turned up much brighter than it was at one point?
Let me ask you this: In the following diagram, once you click on it to make it full-sized, do you see the following:
If not, please take another camera phone photo and post it here. You can upload it directly to this forum via the little camera icon at the top of the edit box.
I don't want to take the thread off topic, so just a quick note to say that no, I didn't mean to imply that adambrandrick111 has malware on his system. It was just a "watch out".
This was a nasty little bugger that very nearly bit me. It masqueraded as a genuine MS security essentials popup, while in fact that was the trojan itself. It would have been set off if I had clicked "repair the problem" immediately. Luckily I didn't, I just closed the page, but it had already got a foot in the door. A scan found the trojan in C:\Users\Dag Fosse\AppData\Local\Mozilla\Firefox\Profiles.
Whew. Close call. This was Firefox, Noel, so I don't know if you have anything for that?
Back to topic. This one beats me.
Only thing is to be sure you have good antimalware software on task.
One of the reasons I prefer IE is that the security zone concept works. Microsoft just doesn't populate the default settings to be particularly secure - they prefer you see all the ads and glitz.
I've tried editing the monitor settings an uses software such as calibrize to do so with no luck.
Those images are not like that at all.
There is obvious lines in every picture an the bottom right is checkered black and grey, not a black line.
I didn't take a picture because I think I've just given up on this, and I am going to return the graphics card before the opportunity to do so runs out. I'll jut have to try and upgrade to a new computer very soon.
Thanks for all your help guys. I guess it's just one of those things.
Your monitor is showing your images WAY too brightly. I believe this is the problem. It's so far out of norm from the expected 2.2 gamma that you're seeing the posterization in very dark places that most folks don't see.
Check your on-monitor controls and adjust them so that you see the test pattern as I have described it.
You might want to try things and see how much better your performance is before taking the new card back.
I appreciate the help but I can tell you it's not that. I have tried changing the monitor settings on the monitor itself countless times throughout this, using test images such as the one you showed me to get it right, and all it does is make the monitor either very bright or very dark, an weird shades of red or blue or something. The banding is still there albeit blue-er or red-er than before.
I've already returned the card as the shop I got it from has a short returns policy, and I would agree the performance was or would be better but at this time I had no plans to and couldn't really afford to upgrade the card, and as I now plan to try and upgrade to a new computer, unless this one miraculously fixes itself, I will be choosing one with a better card already installed so it would have been useless.
Thank you for the idea though, I might toy with the settings next time I'm online but I'm not relying on it.
I think the tip of the iceberg that is at the root of this problem is the fact that you're seeing things that should be almost black as gray.
Something is either programming your video card's (and onboard video adapter's) brightness/contrast/gamma settings WAY out of whack, or your monitor itself is somehow way off in its own calibration.
Something you've done that eliminated one of the parts as a suspect was in error. Either that or we have to begin to question the statement, "computers can work".
Sorry we couldn't come to a good resolution. It's things like this that drive people to throw away everything and start fresh.
I'm going to get a new monitor as well whenever u get a new box, it doesn't feel like a new computer if you still use your old monitor haha, and yeah I'd hate to still have this problem after buying a new one so just going to replace everything.
I'd have likes to be able to fix it but things like this happen sometimes.
Thanks again for all the help.
Right just something I've been thinking about.
Lundberg02, why do you say that it sounds like bad RAM?
The only reason I ask is that I upgraded the RAM about 2 years ago, and it made my computer really fast, and now in the past few weeks it's been unusually slow and laggy. Why do you think it's the RAM?
I want to be sure before I go out and buy some new RAM because you usually can't return it, and like I've said if I can't fix this problem with the computer I will be getting a new one so any upgrades to this one will be a waste of money.
