My two cents.
- Movies as of recently are actually mostly shot in 21:9 not 16:9, so an ultrawide can make sense if your primary purpose is for movies.
- For your usage a VA panel may actually be preferable. You don't need the high fast response times of a TN panel, which is preferable for gaming use. VA suits your use case better due to better contrast ratios in general. (FYI - most TVs currently use VA panels)
The PRISM X315 PRO would probably suit your needs.
For a cheap 27" option, you can look to try the Monex M27CQH. Below $300 after coupons for a 27" QHD 144Hz curved monitor.
