I own macbook pro 13 2011 base model, and i bought cheap dvi cable from ebay to connect my mac to external display at my uni, it works, but colours are inverted on external display. It is fine on my mac display though and even shortcut ctr+opt+cmd+8 works to invert colours, but then colours are fine on external display and inverted on mac. I want to use both of them so does anyone knows the solution? Could the cable be faulted? Thanks
Got a tip for us?

External display problem, colours are inverted

Nice, theoretically that's impossible because of the way DVI works. What kind of external display are you using?
Edit: After reading up on this issue it appears to be a problem with the Thunderbolt firmware on the 2011 MBPs. Is the firmware on your MBP all up to date? Additionally, which version of OS X are you using? For some users OS X Lion fixed the issue, for others Lion had no effect.

could it be 22.1?

No, there is update just for airport utility and I've just updated to 10.7.3, it didn't help. I remembered that i have once connected to another display with cable it came with and it worked fine, with the cheap cable I bought for my uni displays this happened.
your updated than if there is nothing there, do you have a way to test the cable on the onther MBP or another monitor?
I have booted windows and it is same thing, inverted on display, fine on mac, when i turn invert colours on in windows it is vice versa, fine on display, inverted on mac.

i tried on different display and it is same, but the model i tried with was the same too, I'm gonna try it with another mac now,
Okay, tried with another mac which was same model like mine, same effect too, and tried with 15 incher one who had windows booted and it didn't work at all, when i turn display off and connect it to that mac, it recognises the monitor, (the screens turns blue for a sec) when i turn the monitor on it automatically disconnects
Could it be my adaptor? Because it isn't original one from apple store, just quite high quality fake from ebay, the only thing which confuses that it did work with another monitor and original dvi cable

I think it is the adaptor or cable, because i started notice that screen blinks sometimes and not always want to connect, will try to get a proper dvi cable from somewhere and figure out is mine one faulted, if not then gonna look for genuine adaptor, thanks for help, let me know if you have any oher ideas whitch could help.
What brand of adaptor are you using? I've seen reports of this happening with the Moshi adaptors that Apple resells. Another new DVI cable will help narrow down possibilities, but theoretically this is impossible because DVI is a digital standard; if flaws in the cable, adaptor, etc. are corrupting the data sent to the TV the connection simply won't work, unlike VGA displays where you can have displays tinted red, green, blue, yellow, cyan or magenta because color pins have been severed.
I'm convinced that there's a firmware issue with the Thunderbolt controller chipset that Apple uses. This should be brought to their attention, but I'm not sure how one would accomplish that.
And the information you provided about your thunderbolt chipset is... interesting. Just so we're on the same page, this is the page I want you to check;
(I don't have any Thunderbolt hardware because I'm using an early 2010 MBP, so I can't test this issue myself.)

Yep, same page. As i said my adaptor is fake, maybe thats what causes this. However it worked on different display with cable it came with.

Believe it or not my cheap cable caused the issue. I had opportunity to check it on different display, and when i connected my mac with cable i bought it had same effect - inverted colours. When i used same adaptor but original cable that came with the display i used, colours was just fine and everything worked well. Looking for new cable now, thanks for help anyways!
