Since he said he did use it and managed to get 30Hz 4k (of course it is not 4000 but just 3840pixels.) - I am curious how he managed to do so. HDMI is included but the 5770 is quite an old piece of hardware. Since you did it - my MP and HD5770 but with DVI should do 4k as well, right? (at 30 Hz as most macs do these days - seems there's no 60Hz at all - maybe except the MP but it won't never be in my price range unlike all those MPs I had in my life.) I am NOT planning to switch to a new mac pro since it is not really perfect for music and just more than expensive so this MP will be my last and it's still a good machine compared to most macs - and adding HDs is hard on any new mac - so next mac will be different and hope to keep this mac for some years for this reason). right? and this is sort of an old GFX card but I got it for 150 and needed to not be annoyed by 1minute of using zoom with GeForce 120 *G*
I strongly assume you must have had something to get this done and I read those 2 DVI connectors on the HD5770 won't do 4K. so - since Display Port is not present on this card - do you think it can handle 4k? I don't think so, but since you managed to do so - what was the trick? a converter? I had to buy one since Yosemite slowed down all GFX a LOT. Well I read you (apple fiend) are using Display Port - but the HD5770 has only 2 DVI ports plus HDMI (I am running a 2009 MP 4,1 8core with HD5770) Hey guy, I found this thread - some questions on 4K on MacPro This is the Dell P2815Q - their cheap 4k? Reviews do complain about mouse lag - I wonder if they are doing some processing and adding frame lag (I have no personal experience with this model though) The Dell *probably* doesn't have anything like that being a monitor rather than TV but it might be worth checking. I have to keep turning it off Motion Estimation/Correction when I hook my laptop to my TV or it adds a terrible lag. The other thing that makes a big difference with a 4k TV is if it has any sort of motion compensation. When I first got the display I had to run at 18Hz, and that was really hard to use, but I'm able to use 30Hz without much complaint (NOTE: I don't use photoshop so can't comment specifically there) I've used it on w/ my 30Hz Seiki 4k TV (SE39UY04) and it does seem to help, but hard to quantify. Other threads have recommended smoothmouse to help with mouse lag ( ).
The 5570 is a way, way better card that that. I had a 2011 mac mini with the AMD 6630, and it had no problems in 2D. I don't really know how to diagnose where the problem is coming from.Īs others have said, that video card can easily drive 4k. My Dell 4K, runs at 4K 30Hz, is the problem just that the refresh is slower and maybe not my GPU at all? If thats the case, that changes how I see things. With every OS X update, the performance gets better, but its not perfect. I'd be ok to grab the GPU 7950, and see if it works, and if not just return it, but I'd rather not deal with that hassle, and just have a better idea if it is the solution to my problem. Its easier for me to spend $500 on a GPU now than to spend $3,000 on a new computer. Does that make more sense? I'm just not sure if its a CPU or GPU solution, or if its worth it just to wait it out and get the new Mac Pro. The best way I can put it, it feels like very very slight input lag, where I would move the mouse physically, and the cursor on the screen is micro seconds slower to respond. The problem is minor, but noticeable when working. Everything runs great, I can play videos fine, games, even 4K content, and only very slightly glitches. Its hard because you can only really see/feel the issue when using it. Comparing the Harpertown Xeon in a Mac Pro 3,1 with a modern i7 Haswell desktop CPU shows a large performance gap too: īack in January Anandtech recommended 2x R9 290X cards for the best 4k experience in Windows but your MP 3,1 will not supply enough power to run a pair of such high performance cards without serious modification and an external PSU. If that doesn't speed it up, the slower DDR2 RAM and a 6 year old Xeon CPU could be the bottleneck, in which case you would need to sell the whole lot and start again with a newer workstation. The GFX card is the obvious place to start, a Radeon 5770 is very underpowered compared to newer models: If you change the 5770 for a much newer card and still have lag you will have to change everything from the ground up. Difficult to say if 4k is viable when everything is so out of date apart from the OS.
