I wanted an inexpensive way for my 2010 Mac Pro with original stock Radeon HD 5770 video cards to drive a 4K TV as a computer monitor. Avatar clash of the benders hacked unblocked. I'd read conflicting reports about whether it would output 3840 x 2160 4K video, or not. For the benefit of anyone else interested in doing it, I'm posting my results here that it does.
I'm not interested in playing video games, just in using a 40' Samsung 4K TV as a monitor for CAD work and viewing some 4K video. The HD 5770 will output 3840 x 2160 at 24, 25, or 30 Hz with excellent results. It will not output 4K at 60 Hz.
All that's required is a $30 (perhaps less) ACTIVE Mini Display Port to HDMI converter, and possibly depending on your monitor or converter, SwitchResX, which can be downloaded for free unless you want to pay for some of its additional features.
You must use an ACTIVE converter. A passive converter will NOT work. It can be tricky distinguishing an ACTIVE converter from a passive converter, because some passive converters say they support 4K (they do, but not from an HD 5770 video card), and some ACTIVE converters are not marketed as ACTIVE. I used a Kanex KIADAPT4KW, http://www.kanex.com/mdphd4k-adapter, which accepts DisplayPort 1.2 and outputs HDMI 1.4b compatible 297 MHz pixel rate signals.
Leap office for windows 10. The Samsung monitor I used showed up in the Display Preferences (and About This Mac) as a native 4096 x 2160 monitor, when in fact it is 3840 x 2160 TV/monitor. I suspect that was because of an EDID problem that could have been in the monitor or the converter. In any event, it did not work correctly when selecting the Native setting or 4096 x 2160 in the Display Preferences. But SwitchResX can be used to easily select the correct 3840 x 2160 output at either 24, 25, or 30 Hz (or 1080p when you don't want the 4K output), and it will default to that setting each time the Mac Pro is booted up.
The results were excellent on CAD and 4K video. I hope this is helpful information for someone else. It certainly would have helped me earlier.

Sep 03, 2010 I just bought the XFX ATI Radeon HD5770 for my Mac Pro (from Mid 2008). My current card is ATI RadeonX1900 but I want to replace it with a new one. I was aware that some cards aren't compatible but I read in some forums that tha HD5770 would work on Mac Pro. Problem is once I install it onboard my screen doesn't even turn on. Card's fan is. Feb 18, 2011 Hello, I am a new user. I recently replaced my old 7300 GT with a ATI Radeon HD 5770 card but I miss the neccessary drivers. They wasn't part of the 'Graphic Card Upgrade' I received for my Mac Pro 1,1. I looked on ATI / AMD site and they don't have them.

I ordered a new video card for my 3,1 Mac Pro and accidentally ordered the ver that doesn't say 'For Mac Pro' not realizing that there was any difference. It seems that the video card should work, if I could get it in my tower! The difference between the two ver seems to be the length and shape of its support arm(can't figure out what to call this part), the FOR Mac Pro ver is an inch or so shorter than the other one.
I saw someone suggest cutting it off with a hacksaw, which I'd really rather not do. So I was wondering if anyone has tried removing the arm/case part? It seems like it might work, but I'm concerned about it exposing any important parts, it is covered with the important legal stickers.
Or does anyone have ideas short of the hacksaw plan to get this bad boy to fit in the darn machine?
