Does my 2011 MBP with 6490M support 4K display?

    Hi. I know this might be a silly question but I am really thinking about purchasing a 4K 24-inch display, Dell UP2414Q for my 2011 MBP with AMD 6490M graphics. I want to get "retina" effect using HiDPI mode in the OS X.

    I know it is not possible to run the 4K display at 60Hz, but I was wondering if it is possible to get a 3840x2160@30Hz. Any suggestion will be much appreciated.

    Thank you!

    I don't think the drivers support 4K. It supports more than one stream at 2560 x 1440, but presumably not 4K.

    I've got the exact same machine and it doesn't support anything above 2560x1600 and I think even that is if you get a miniDisplayPort-to-DisplayPort adapter. The reason for that is the not drivers, but on the chip firmware which is something Apple has very little power over as it's an outsourced part.

    That resolution is generally the highest resolution laptop GPU's can offer with the exception of some fairly recent chips.

    I'm running a Early 2011 MBP with the 6490M with a Dell P2815Q at 4K 30Hz. I have no issues at all. I don't game. I just use it with Xcode for the most part and Adobe CC.

    Which adapter

    @iCreate - how have you connected your MBP to your monitor? i.e. did you use a special adapter?

    I just used the display port cable. It gives me native resolution of 3840x2160. I'm surprised so may people here say it can't be done. It's 30Hz and the mouse lags but you get used to it after a while. The only issue I've ever had with it was it didn't wake from sleep at times so I would have to power it off then on again. I used it for about a year until I saw the LG 34UC87 curved wide screen monitor and recently bought that.
