Interesting.
As another FReeper pointed out, unless it’s your job, it’s almost impossible to stay abreast of all the tech specs.
Even though IT is part of my own, I only delve into specs when it’s pertinent to either troubleshooting or procurement pursuant to a goal.
Your experience is just another level of 4k troubles I’ve read about anecdotally, my own video problems knowingly rooted in a laptop with now-known wholly inadequate video ability (a hand-me-down).
It was a point of humor when I recently observed an IT dept dealing with vexing hardware and video issues pertaining to an IP based security camera system.
Ironically, it all comes back to KISS.
No disagreement with any of that. Esp. the difficulty keeping up with the tech — even old tech if spec sheets are muddled or in some cases incomplete (such as some Nvidia specs that state maximum resolution but not the refresh rate @ that resolution.)
Ah, well, there did turn out to be one bonus: I was assured (not by you!) that upon installation of the NVS 510 card that the motherboard video outputs of my HP6300 would shut down and only the outputs of the graphics card would be available. And that the BIOS might not allow parallel operation. As it turns out, the MB video outputs DO still work without me mucking around in the BIOS. Since 1920 x 1200 from the MB works great on my smaller monitor, and I can’t detect any useful difference in MB processor speed regardless of the smaller monitor’s source, I’ve left said smaller monitor on the MB video (DP) output, which saves me an adapter or an adapter cable, and gives the NVS 510 card it’s full capacity to run the big monitor.
“KISS”, as you said. :-)
