Want a 43 inch tv for bedroom which make has best picture to watch in freeview HD ? Just general tv watching
At that size you don’t want a UHD 4k set and as you want watch free view HD. I would go for Sony/Panasonic but a more affordable ones are from Samsung/LG. I would stick to normal LCD or better still QLED. OLED are only useful for watching streamed movies from likes on Netflix etc. keep away from old Japanese brand (like of JVC TOSHIBA etc, these names have been sold on ) as well as raft of Chinese brands.
We have a JVC and a Logic both sharing the same aerial for Free View. Both have excellent quality reception but it depends of course on the strength of the signal in your area.
