It was quite entertaining reviewing all these threads and opinions - not seeing a single comment from someone who actually
owns an 8K computer monitor. So yes, we're definitely a niche.
All I can tell you is that the images look gorgeous on it!
I have had the Dell 32-inch UP3218K 8K monitor now for about a year for my main workstation (an Intel 13900KS running at 6.3GHz on its P-cores). The monitor is driven by dual 4.1a DisplayPort connection on a GeForce RTX 3090 Ti display adapter (also overkill). I run it most of the time in 10x3-bit (30-bit) color at 48Hz for my editing my Z9 48MP images (and switch to 8/24-bit/60Hz for video editing).
It is a luxury? Definitely, but then again, several of my lenses run over $3K each, so I guess you could say it's all relative.
I also have several other computers running 32" 4K monitors. All I can tell you is that I'd really miss the UP3218K if I had to revert to using one of my 4K monitors for my main system.

The one thing everyone can agree on is that film photography has its negatives. It even has its positives and internegatives.
