Windows 10 Pro with UHD 630 Won't Allow 4k Selection

[GBENN9]

I have a brand new Dell Inspiron 3471 with UHD 630 graphics. Out of the box I was able to select and display 4k on my 4k monitor with no issues. I upgraded the built-in 1TB HD with a brand new 2TB SSD and installed a fresh copy of Windows 10 Pro. Now, with the exact same monitor and HDMI cable, I am unable to select 4k resolution. I've updated all drivers directly from Dell with no joy. I've installed and run the Intel Driver & Support Assistant, which updated the graphics driver to the latest, still with no joy. Running the Intel Graphics Command Center, I see that all resolutions up to 3840 x 2160 (60p Hz) are supported under the Display\Information tab, yet under the Display\General tab the highest resolution available is 1920 x 1080 (recommended). Multiple reboots yield no results. I've attempted to add a custom resolution from the Display\General tab, manually entering 3840 x 2160, 60 Hz, 0% Underscan, but each time I apply those settings I get the following error: "Error Occurred. Unable to add settings. Reason: Mode not supported."

I'm at a complete loss and cannot understand why the built-in Windows 10 Pro OS from Dell allowed the selection of 4k resolution out of the box, but my fresh install of Windows 10 Pro on a new SSD does not support this selection.

Any and all assistance would be greatly appreciated.

Thanks in advance,

Gary

I had this happen to me in quite a similar way. It turned out that I somehow damaged the HDMI cable either when removing it to work on the box or when I put it back together. You could try replacing the HDMI cable and see if the same thing happened to you. Remember the rules for cables, (1) If it came with the monitor, it is crap, so discard it and (2) you get what you pay for; you get crap otherwise. Yea, I know; I do have to work on my negativity...

LOL! Thanks for the advice, @n.scott.pearson​ . I tried another high-speed HDMI cable with the same non-results. appreciate the idea, though....
