49 inch
TCL 49S405 49-Inch 4K Ultra HD Roku Smart LED TV (2017 Model) https://www.amazon.com/dp/B01MYGISTO/ref=cm_sw_r_cp_api_AxzoBb5VDZX39
ok i think im gonna go with this TCL that /u/ZeroCorpse linked just the 49 inch version i think because 55 seems massive (but the best deal).
then eventually get a tv that supports HDMI 2.1.
thanks!
