RGB colour output format via HDMI/DP

Hey Guys,


So i just bought a Dell u2410 screen the other day, and decided to hook it up via HDMI, It's being used for photo-editing, I tried to calibrate it, but in the sRGB mode i need to use the colours come out terrible, Reds are orange, etc. The screen itself, and it's settings arn't the problem. The problem is the Colour output of the MacBook, over HDMI and DisplayPort I've found it outputs the old YPbPr colour format, which for me is useless. if i connect it via VGA it'll output proper RGB colour format, but VGA is pretty crappy, and i ideally need to use a Digital output, I've searched all over the net for a solution, but haven't found one. one thing i did find is it will supposedly output RGB over DVI, but alas i don't have a DVI cable and do not wish to have to buy one...


so what i want to know, is it possible to change the output colour format for HDMI and DisplayPort to RGB instead of YPbPr?


Note 1: If i boot into Win7 via BootCamp it outputs RGB and has the option for YPbPr...

Note 2: It isn't the ICC colour profile that's the problem.

MacBook Pro (15-inch Late 2011), Mac OS X (10.7.3)

A Google search took me to this discussion at a Dell forum. Unfortunately, no solutions. It seems as if the only solution at this point is to buy an Apple Thunderbolt Display. Not the solution that you guys are looking for, I know, but if you read the discussion it's stated specifically that Dell does not test it's monitors with Apple equipment.


Sorry,


Clinton

Thanks for the link to the Dell discussion forum.


Reading that thread and half a dozen others on the Apple forum is really a sad day for me, having owned every single iphone, ipad, Mac mini, MacBook Pro that Apple has put out, the latest Retina MBP has completely disappointed me. It seems neither Dell nor Apple care about the users who need the correct color space for digital photography.


I bought the latest and greatest MacBook Pro this year and it doesn't connect to an external monitor in the correct color space for me to do digital photography? This is really a sad situation. Will be returning it as soon as I migrate the data out.


I would gladly buy an Apple Thunderbolt display, but just can't stand its glare, not to mention it's limited resolution @2560x1200 which is smaller than the 30" @2560x1600.

I have a U3011, and my MBP retina 15inch
(10.8.2) only sends YPbPr space to the display via miniDP to DP cable instead of RGB. If I change the settings to RGB, the color is all funny looking. For all professional purposes this is useless. Nobody from Apple or Dell is willing fix this.


U3011 only uses HDMI 1.3, so you won't get the full resolution. I also have used a mini-DP to dual-DVI adaptor. It gets RGB from MBP, the text is all garbled for anything above 1600x1000 .


I am at my wits end.
