Quick update:
Bought an LG 55" UHD TV from an Abenson sale promo last weekend.
Just installed a Zotac Mini 2GB GTX 1050 for ~Php5,800; sold my GPU to an ofismate for P1,500 (2 gives na para hindi makatanggi).. Total cost P4,300
Tested with footages from GoPro Hero4 at 4k reso, PQ was superb. Tried downloading Sony 4k demo videos, so far smooth playback... I guess for 4k playback, the GTX 1050 played smoothly.
Haven't tried watching a full 4k movie, been very busy. I'll test this again on a 79GB file 4k movie. Haven't tested the HDR capability of this yet, hindi ko lang alam paano malaman kong HDR na ung movie (anyway that's for me to explore).
