  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

4k Graphics Cards for older Mac Pros

Well, gotta eat my hat here, I was going off what I was told by a couple of the nVidia support engineer guys and my own experience. Didn't have any luck trying it myself, but it's been a little while since I worked with it. Well over a month, probably close to two months...

Anyway, I'm getting 4K 60Hz 8bit 4.4.4 out of the card now with the latest drivers to the Samsung HU8550 and the Sony 4K projector. I have not tried the Samsung F9000 as it's not in a good spot relevant to this computer, but I see no reason why it would be any different, besides I have put the original HDMI 1.4 OneConnect box back on that TV anyway to keep it compatible with REDRAY, but that's a whole other rant.


I will still maintain that the HDMI 2.0 on these cards should not be a deciding factor or looked to for future compatibility. IMO, the lack of HDCP 2.2 is still a deal breaker and this is not something that can be added via firmware or driver updates. HDCP 2.2 will be necessary as we move forward to support content from any upcoming 4K BluRay format or for the various 4K streaming options. Sony, MGM, Disney, etc.. all require HDCP 2.2 in order to distribute and view their content at 4K. Netflix only works in 4K on integrated devices or on external devices with HDCP 2.2 support.

That's great new. Can I buy GTX 980 with the LG31 inch 4K monitor and expect 4K playback in all its glory
at last?

What do you mean by "4K playback in all its glory" ...? A lot still depends on your system and how capable the rest of it is in relation to the GPU. The GTX980 will do a fine job running the new 31" LG monitor.

As much as I am lusting for the low TDP, reasonable price, HDMI2 of the 970/980 cards Jeff's note about lack of HDCP2.2 is, as he notes, the deal breaker. Bummer.

Do keep in mind that other than the top tier of UHD TV's, nothing is supporting HDCP 2.2 yet. Yamaha and Denon couldn't even be bothered to include it on their new HDMI 2.0 AV Receivers they released a couple months ago, but will offer it next year. WTF... I feel sorry for all the people who jumped on the HDMI 2.0 bandwagon this year to build a new home theatre and will find out in the next year or two that most of what they bought this year is half-baked, incompatible junk. And part of the problem is that other than the Sony X10 media player and the Samsung Media Packs, there is no HDCP 2.2 compliant content distribution yet.

I wouldn't consider the lack of HDCP 2.2 a deal breaker if you need the other functionality of these GPUs. Just saying that there's nothing future-proof about them. And like all the current desktop monitors and other new 4K+ hardware, we're still waiting for interface standards and connectivity issues to be sorted out.
 
Salient point Mr. K. I think I'll roll with the GTX 970 4GB version since it's a couple hundred cheaper than the 980 and use the savings on a next gen die shrunk GPU down the road that should be even better on TDP, faster and (if we're really lucky) will properly support HDMI2.1, DP1.3 and HDCP2.2.

BTW, how important is G-Sync and/or ACX 2.0 on the Maxwell GeForce cards? Are the over clocked variants worth the extra coin for want we do?

My initial install would be a 5,1 MP tower with an RR-X in #2 running RCX-Pro, Adobe CC, FCPX mostly. Need to drive a Sony X850 65" via HDMI as well as a 30" ACD for GUI. Will likely end up in a PC down the road.

I am aware that the 9xx cards might not be well supported on OSX and that the nVidia driver will probably be required.

BTW, your notes only make me more frustrated with the dysfunction of the HDMI ecosystem. If I was Oliver Stone, I might wonder if the stakeholders who want to delay the capital expenditure on UHD gear as long as possible are somehow manipulating the process…

G-sync is not important unless you need frame lock with another device or trying to sync multiple screens.

BTW Jeff based on what I am seeing, the limitation for HDCP updatability is limited to the the devices such as receivers and displays. Considering it's simply an encryption change with a latency check, it should be updateable on computers via the OS and video driver unless the HDMI chip manufacturer locked it down before they shipped the chips to the device manufacturers for video cards. This means you may have to replace your display or projectors but not necessarily the video card.
