I'm seriously LTTP because I've just bought my first ever OLED TV. I guess it's an entry level - LG B5. I've never even had 120hz/VRR support TV before.
Anyway, first impressions are really positive. There are quite a few 40hz games on the Pro that I've tried and are mostly great. Starfield at 40hz is superb.
I've also tried 120hz mode on GT7 and it's fantastic. The only trade off I've noticed is the loss of RT, but I can live with that.
I don't think the picture is as sharp as my previous Samsung TV, but it more than makes up for it with the colours, and the pure black.
