My latest wacky ideal monitor spec is actually more along the lines of 32:10. My new laptop is 16:10, 2560x1600 and I've really enjoyed gaming with that. At 18" that panel is really crisp in terms of PPI. I didn't think I would but it's a blast. I'd be happy with 40-45" 32:10, don't care if curved or not, OLED HDR1000 ~120-144Hz G-Sync. It'll never happen but a man can dream. I've thought about getting either two 22 or 24 inch panels and slapping them together but I haven't seen any that match all the specs, yet.
I've mostly enjoyed the CRG9. It took a while for me to understand how to configure it for HDR and then a while longer for GPUs to catch up to use it's resolution/frame rate potential but these days I usually have a lot of fun with it when I'm in the mood.
