And it appears my Dell does support Windows 11 after all.
I found out the Dell was in Legacy mode and switched it back to Secure Boot, and enabled TPM. I ran the Windows 11 setup, and it passed the compatibility check. Windows 11 is now running on the Dell, and I'm in the middle of getting updates and all that.
But now there is another issue. I have a fancy Sony X80J 4K TV I bought at tax refund time in February. The Dell was working fine with the Sony until I turned Secure Boot back on. Now, the Dell logo and BIOS screens no longer show up on the TV at all, and it complains of "No signal" even after the system finishes booting. I had to connect the Dell to one of my HDMI capture dongles just to see the output.
Based on a very quick Bing search (because I'm using a spare Windows 8.1 Gateway laptop and Vivaldi browser for drivers and research) apparently some modern TVs require the latest possible name-brand HDMI cables in order to pass a proper 4K signal from a PC to an HDTV. DRM might be involved too. And all of my HDMI cables on hand are el-cheapo cables packed in with the various plug-and-play games and cheap DVD players I have used over the years.
I will try to lower the resolution to 1080p or 720p before trying it with the TV again. If it still fails, then I may indeed have to get a 4K HDMI cable from a name-brand like GE.

I love foxes, especially the one in my avatar.
