Building HTPC for plex need advice

so these steps should make HDR work perfectly with a gpu that is capable to do so.

he is using GTX 1050 Ti
and my aspire pc running a gt 730 which can’t display HDR according to nvidia matrix page

so when i want to buy another gpu , it must be low profile to fit in.
and be able to give HDR in windows plex (APP not the windows store version)
