        I'll have a look at that one in a minute. The 6670 one I've noticed comes in DDR3 like this http://www.amazon.co.uk/gp/aw/d/B004XANOCO/ref=aw_d_detail?pd=1 would that still work with my computer? I really want to get the 6670 but sometimes you just can't afford something, then I saw the DDR3 instead of DDR5 and thought maybe that will be better for me?

          A DDR3-equipped card will be slower than a DDR5-equipped one, but in your case it might not be noticeable as other factors in your system may be the main bottlenecks.

            I'm thinking in going to go with that one, it's going to be better than what I'm used to and if it fixes the problem then that's all I'm really bothered about.

             

            Thank you for all your help Noel, I wouldn't have had a clue about all this stuff if it wasn't for your help.

              You're welcome.  I know that video card will give you a better computing experience than your onboard Intel GPU.  I just hope it fixes the problem you're seeing - it sure seems as though we've eliminated everything else.

                Sorry for a late reply, I've only just got around to buying a graphics card.

                 

                It's bad news though.

                I bought a VTX3D AMD Radeon HD 6670 with 2GB DDR3 memory, and I've just installed it all went fine but then I wet onto photoshop etc and the problem is still there.

                I tried changing my color management settings and the settings in photoshop back to sRGB....etc from Adobe RGB 1998 and restarted but it's still the same issue.

                Help?

                  I'm sorry to hear that.  I thought you had sufficiently isolated the problem to your onboard video adapter before.  In any case, the ATI will give you a greatly enhanced computing experience, though it occurs to me that you need make sure all the drivers that were active for the old card have been disabled/removed and the latest ATI drivers installed.

                   

                  Can you take a screen grab AND a photo and post them here, so we can see what you're actually seeing?  The gradient screen grabs you put up before all look clean and smooth.

                    I went back and skimmed the whole thread, and at this point I would look very hard at the monitor itself. I agree with what was said above:

                    I didn't read the whole thread and I may be missing something but I gather the problem could be incapable monitor and getting a better video card may not fix the problem. It also could be bad monitor hardware settings like increased contrast.

                    As long as the monitor profile is ruled out, I think it's safe to say that this is not a color management problem. Photoshop color settings should have no bearing on this. And with the video card also ruled out, that basically leaves the monitor. Which one is it BTW?

                     

                    I would also like to point out that, like Noel, I see no problem with the examples you posted above (nor with Noel's example).

                     

                    PS - the 6670 is a fine GPU. I just got one myself

                      Hi thanks for the replies guys.

                       

                      Does this link work for you? http://img843.imageshack.us/i/imagecsc.jpg/

                      That's a photo of what I'm seeing. The vertical lines is just my camera but you can clearly see the banding.

                       

                      I have removed the drivers for my old card, it said to remove the card itself but I couldn't find it inside my computer and thought that because it was an integrated one it couldn't be removed and is integrated somewhere inside it.

                       

                      I can guarantee its not the monitor as I've tried it with 3 or 4 other monitors that I know work fine.

                       

                      I just don't understand how I was using it and it was fine then instantly this problem arised and now seems unfixable.

                        Well, you had done a good job before describing it.

                         

                        And you see this when your image is displayed with any application?  Have you tried any tools that avoid any form of color-management - e.g., something like the freeware IrfanView image viewer?

                         

                        That sure looks like an egregious color-management problem, but I can see how it could be a monitor problem as well.  But it's hard to imagine, assuming your answer to the above question is yes (it's like that from any app) that it's some kind of system software problem.

                          Yes it's the same from any app.

                          What does that mean in terms of where to go from here?

                          Thanks.

                            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?

                                              No I only have a VGA slot on my monitor.

                                               

                                              Well previous to this I was creating 2D textures for 3D models so I would have definitely noticed that.

                                                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:

                                                     

                                                    • Relatively smooth gray gradients for the two big vertical columns.

                                                      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.

                                                                Make sure you get a decent monitor first. If you get only a computer box and use it with your current monitor you most likely will still have that problem.

                                                                  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".

                                                                      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.

                                                                      1 2 Previous Next
