There's seriously no incentive for these large companies to improve, instead they're cutting costs for profit because most average users don't care.

Please, PLEASE don't buy budget or mid-range TVs from the larger companies/name-brands, none of them are good. Instead, look at TCL, Hisense, and Vizio. For example, the TCL 5 or 6 series, the Hisense U6G or above, and the Vizio M7 or the P series.

Any of the highest end TVs (LG C1 and C2, Samsung Q90, etc.) are great, though, because of course they are.

Sir you speak the truth & I ended up with a Q90A last year after a few attempts with some mid-range models.
