Update Video Card On Mac For 4k

I would expect you will not be able to drive any apple 4k display since it will require thunderbolt, and that is simply not possible on the classic Mac Pro's But you can drive other vendors displays. Here's what I know: 4k x 60 Hz displayport 1.2 SST GTX680 Mac edition (what I use). Has bootscreen on other ports, but will get no boot screen on 4k display.

Hello guys, I have been running my 2008 Mac Pro(2x2.8ghz Quad Core) for a while now with the basic ATI Radeon HD 2600 XT 256 MB card in it. I do a lot of photo editing on my computer and was thinking of upgrading the memory, installing a SSD drive and upgrading the video card to either support 4K or HD monitors. Re: Video Card upgrade for mid 2010 Mac Pro 5,1 Reply Contact I own a Mid-2010 MacPro 32GB Quad-Core 2.8ghz tower and after I upgraded Avid Media Composer 8.4 to 8.8 computer chashes after I do very simple edits or even a simple playback.

I have a 27' for my bootscreen. ATI7950 Mac edition - will not boot with Samsung monitor, not sure about other SST models. Can hook up monitor after boot or boot card in PC mode (no bootscreen) I'd expect any PC ATI/NV card newer than these should also work, albiet with no bootscreen. You could use a second card for bootscreen with the 27' - I've done this with a GT120 & the ATI7950 card. 4k x 60 Hz displayport 1.2 MST I've heard the nvidia drivers don't work well here(?), but ATI cards do work well? No personal experience. 4k x 30 Hz HDMI 1.4 Probably any card with a HDMI 1.4 port will work.

I believe both the mac edition ATI7950 & GTX680 will give a bootscreen, but been a while since I tested. Click to expand.I believe your card does have DP 1.2. I don't actually have the exact same card - mine is a EVGA PC card that I flashed, though I believe they're both reference designs, and probably nearly identical hardware. It seems unlikely e that your hardware is DP 1.1 - perhaps at the time of card release it was software limited.?

I get 4k x 60Hz on the Samsung 28' (SST). Again, no boot screen on that monitor, which is one reason I keep a generic 27' 2560x1440 hooked up to the DVI port. I wish the Samsung had a better panel though (and was bigger). If only my seiki 39' had a DP1.2 port I'd be in heaven.

Hi, no, I haven't as I haven't yet received either the 750 or the 970. That would be most brilliant of course! Ok, with this in mind I'm just going to wait a couple more days to find out. After all the horror concerning 4K and OS X I didn't expect the solution to maybe, hopefully be that simple. I'll certainly report back Do you know if success only depends on the display itself or does the graphics card play a role as well (680 vs the above mentioned with the same display for example)? Thank you very much you two!

Hello guys, I have been running my 2008 Mac Pro(2x2.8ghz Quad Core) for a while now with the basic ATI Radeon HD 2600 XT 256 MB card in it. I do a lot of photo editing on my computer and was thinking of upgrading the memory, installing a SSD drive and upgrading the video card to either support 4K or HD monitors. I have found very little on the subject of 4K monitors and which video card could support it or HD for that matter.

Also wondering how I could run my computer to my 1080P HD TV and possibly put a blu ray drive in my tower as well. If anyone could shine some light on this it would be appreciated. Therer is a startling amount of misinformation in this thread. For the life of me I never understand why people answer questions that they don't actually KNOW the answers too. 'I thought I read it somewhere' doesn't qualify.

With 10.9.2 there is now 4K at 60Hz support for 7950/70 cards via MDP. So they can output fully supported 4K to an Asus or Sharp PQ-321. (The one Apple sells now) I can't speak for Dell, LG, etc as I don't have one.

MANY cards with DP or MDP can do 4K at 30Hz in 10.9. The GTX680 is still limited to 30Hz in 10.9.2. 7950/70 and GTX680 can do 4K at 30Hz via HDMI in 10.9. Again, I can only speak for Asus/Sharp 32' 4K displays because that is what I have to test with. As far as making more pixels appear on an HD TV, it AIN'T GONNA HAPPEN. The Dual Link DVI ports on 2600XT are limited to 2560x1600 @ 60Hz.

You may be able to use SwitchresX to slow refresh rate down to some absurd number and get to 4K but your mouse cursor will be skipping and jumping across the screen like a school girl. A 4K display has literally 4 @ HD displays worth of pixels. Yes, you can fit 4 HD images onto a 4K display without overlap or pixel scrunching. An HD display is 1920x1080. If your photos are larger than that, they won't fit without compressing pixels into a single pixel. Simple mathematic fact. Can you put 5 gallons of water in a 3 gallon bucket?

I have the normal DVI hook up on the back of the Mac and HDMI(DVI) hook up on the TV. Single-Link DVI is good for displays up to about 1920 wide. To go wider, DVI addds a second set of data lines (three more pairs of wires) and is called Dual-Link DVI. Dual-Link DVI cables always have all the pins in the grid populated, Single Link DVI may have two columns of pins missing in the center of the Grid, or may not.

If you are converting from Mini Displayport, the Dual-Link DVI adapter can cost US$100. Most HDMI is only good for up to 1080p (1920 by 1080, non-interlaced). On the 2600, BOTH ports are Dual-Link DVI. Apple Footer. This site contains user submitted content, comments and opinions and is for informational purposes only.
