I bought this TV last week, and it's very bad. Yes, the TV is awesome BUT, this model have red-ghosting issues.
To be clear, when you will watch a TV series on Netflix (in 4K/HDR) or when you will play to a video game (for example : Call of Duty Modern Warfare), you will see red ghosting.
This issue concern 99% of the TV sell by Hisense in America and Europe. It's a hardware problem, and you can have more infos on reddit or here : 2020 Hisense H9G / Q9G series 55" & 65" Owners Thread (No Price Talk) | AVS Forum
I bought this to replace a series 4 tcl.
I bought the series 5 but didn't like the gaming performance not being native 120hz,
bugged me way more than the 4 which wasn't either.
The series 5 is amazing for watching movies without fast motion.
Hopefully this pink thing doesn't bug me I doubt it will or ill just correct it properly in the setting if i can.
I did buy an M series Vizio that i did not like and returned the screen was cracked on the corner so i had to anyways.
