There is Samsung qn90a but no Dolby vision in that tv and only 2 ports are hdmi 2.1
so is the case in Sony x90j ,..only 2 hdmi 2.1 ports ….very tough to manage if u plan to use Xbox , ps5 and a soundbar
Also both these tvs are 55 inches
whereas lg c1 is 48 inches (starts from 48 and goes upto 83 inches) and has hdmi 2.1 on all 4 ports. It’s the best available tv for gaming rn
