At your budget, dami options nyan. Check mo sa Ansons, dito sa PDVD marketplace o Sulit ang LG, Samsung or Sony. Most (if not all) 55 inchers are already smart, bring a 4k HDR movie material in external drive to compare picture quality, the bigger file, the better (30GB and above). Check for black level (the blacker blacks, the better), contrast ratio and overall picture quality. Good luck.
And btw, stay away from TCL.
