Does an Optiplex 9020 officially support two 4k monitors?
Having some strange issues with this desktop. Setup is:
Optiplex 9020
32GB RAM
2x AMD Radeon HD8490
2x Dell UP3214Q monitors
Each monitor is connected to one card with an HDMI cable
Issues are:
1. PC will randomly have an error it is 'out of memory' and will reset size and position of running programs.
2. When rebooting, only one monitor comes on. Need to push the power off/on on the second for it to be detected.
What I have tried:
Replaced HDMI cables
Updating graphics card drivers
Updated BIOS
Set Virtual Memory to system defaults
Now I am wondering if maybe the PC does not even officially support two 4k displays? It was purchased in 2014, don't think 4k was very well supported back then.

The Radeon HD 8XXX does not. AMD Radeon™ R5 235X, Radeon™ R5 235, Radeon™ R5 230, Radeon™ R5 220, Radeon™ HD 8470, Radeon™ HD 8350, Radeon™ HD 8000 (D/G variants), Radeon™ HD 7000 Series (HD 7600 and below), Radeon™ HD 6000 Series, and Radeon™ HD 5000 Series Graphics products have been moved to a legacy support model and no additional driver releases are planned.

AMD Radeon R9 290 Series
AMD Radeon R9 270 Series
AMD Radeon HD 7800 Series
are required for 4k.
All of the Radeon HD series 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000 and some of the R5 series are now Legacy. This means the latest driver for AMD DOES NOT SUPPORT and WILL NOT Auto detect.
AMD recommends using DisplayPort 1.2 certified cables with a length of 2m (~6 ft) or less when driving 4K monitors. HDMI is not the correct interface for 4k. Finally, the monitor itself may be the final component to consider for resolving any issues that arise with 4K systems. The DisplayPort receiver in the monitor must perform according to specifications, in addition to the accompanying hardware and firmware implementation’s ability to handle 4K timings without issue.

Thank you, very informative. Surprised to hear HD8xxx series does not support but HD7xxx does. I thought HD8xxx is the newer family of graphics card and so would support higher quality monitors.
In any case, you provided good options. Is there any specific one you would recommend higher than all the others for this PC?
If I'm understanding correctly, the AMD Radeon R9 290 Series is the newest one?
Will the Optiplex 9020 support that card?
I will change the cable to DisplayPort but as for the length, I will need at least a 10ft cable because the monitors are on a standing desk. Will that significantly impact the performance?

R9 290 is a monstrous power pig. So no this is not working
there are specific proprietary cards that likely work.
The price is likely not going to be helpful

Supports multi monitor 3840 x 2160 at 30hz via display port NOT HDMI.
Display port is NOT optional for 4k its required.

Thanks this one looks great! I suppose only one of these would be fine, correct? And I can plug in both 4K monitors?
These use MiniDP instead of DP...that will still work well for 4K? The displays have MiniDP connections so no need for converters.

Mini DP to DP is a passive pass thru conversion OR a cable with mini on one side and DP 1.2 full size on the other. Yes 1 of these cards should work fine.

Actually looks like the #2 issue is still present:
"When rebooting, only one monitor comes on. Need to push the power off/on on the second for it to be detected."
I had reboooted a few times when I installed the card and it seemed fine..but today the user of the PC reported that it went dark again.
It is always the same monitor.
The cables used to connect to it were replaced so that's not it.
What else could it be, are there any monitor specific settings I can check?
UPDATE:
Found this: http://jmswrnr.com/blog/the-firmware-issues-of-dell-up3214q-and-up2414q-a00-monitors/
This seems to be the same issue. I checked the problematic monitor is Rev:A00. Unfortunately out of warranty so I cant ask Dell for a replacement unless I extend that.
