A follow-up update, I loaded the 1030 in a SFF i5 with 4Gb this morning, and popped over to the client. Things went well thru the checkup: Powerpoint went without a hitch, of course, and their video from a recent event looked SO sharp at 4k. Thanks so much everyone who gave input! :toast:

There were just two little hiccups. First, the end of video has a plain white background for their sponsor notifications, and in the back, at about a 5% (watermark-type), you see the video of people at the event. On one screen. The other screen only has a white background, no walking people.... The double annoying thing is that's the side with the DP to HDMI adapter which shows the people walking, not the straight HDMI.... :wtf:

I think he'll be ok with that, but when we were getting ready to leave, he asked about a third monitor to drive a small 15-17" monitor to manage the whole setup..... Looks like I'll need to roll the price of a second card into the whole bundle, and get another one :ohwell:


edit: a quick note on that 1030, it's a low-profile, but comes built normal, so you have to swap the riser. Unfortunately, the riser is attached with one screw buried under the heatsink, which has 4 tension screws, 1 of which has a tamper sticker. I took a razor blade to mine, in case I had to return the card, but it's something to note for anyone interested :)
You need to calibrate the screens if you want them to look the same. The monitor with disappearing people is either too bright or too saturated (or too low quality and then you can't fix it).
If you don't have a display calibrator (most people don't), use the big image here: http://krazyblog.net/2014/12/display-calibration-in-phones-and-why-it-matters/
Put it on both screens and try to set them up that so that every shade in there is visible on each screen. You can also google for better images like that.

I'll certainly try that, but I'm afraid that won't fix it... I swapped the connections, and the "issue", if it can be called that, followed the output. In other words, when I reversed the HDMI/DP cables, the people showed up on the other TV.... Still, calibrating can't hurt :)

You can look at the gamma curves being applied by the driver to each output as well.

The TV's HDMI input is configured for limited RGB signal (like for TV, range from 16-235), while the DP is configured full 255 levels (like for PC).
Look in the TV setup, there should be a setting for that HDMI to say "full range" or "PC".

As for the extra input. I suggested previously that cheap Quadro (4 outputs, 10 bit), but... who listens?
