Xiaomi sells 6bit+FRC panels as true 8bit color
Redmi 27 60Hz (RMMNT27NF) -> MV270FHB-N20 (6bit+FRC)
Redmi A27 100Hz (P27FBA-RA) -> MV270FHB-NX0 (6bit+FRC)
There are many twin brothers from Chinese vendors
100Hz 6bit+FRC - AIWA MF270A | Lime F270L
165Hz 6bit+FRC - MSI G2712 | Cooler Master GM27-FFS
Forgive me for the advice to buy Xiaomi. I was a fool.
True 8bit FullHD is a lie. Uncle Liao cheated again.
