Please try re-reading my original post!!!

The high res is needed for good text resolution of documents, spreadsheets, etc. Possibly a little light CAD work.

I am using the display primarily as a PC monitor. As stated, movies (and You Tube vids, etc.) are secondary and indeed I have no such “entertainment” input source that comes close to needing a 4k display.

I use 2 screens for that work

I've had success running my 4K monitor with my old Windows 10 with i7-2600K CPU using the internal graphics support. I wanted a wide screen, so I purchased one that does 3440 x 1440. That one would not work on the old i7-2600K machine. Literally, the BIOS crashed and wouldn't boot my disks. I thought the i7 was defective and downgraded to an i5. Same problem. The i5 was fine on the 4k monitor. Even an auxiliary video board wouldn't fix the problem. It was OLD BIOS as the root cause. 2013 vintage.

I'm running current machines on the 3440x1440 monitor with inside CPU graphics support to HDMI. Crystal clear. I'm writing software 12 to 16 hours per day, so poor clarity is unacceptable.

My large format monitor is an LG WQHD. An nVidia Quadro 7200 video card is in the laptop. The 4k monitor is an LG HDR 4k. The i5 is driving the 4k at 1920x1080 with internal CPU Intel HD Graphics. The 4k monitor doubles as my 4k Bluray player display.
