Slower because not as many want to pay that much money for a tcl. When they had the bestbuy cnet discount that was probably the price the set should have been at launch.Unfortunately this thread is kinds slow, so maybe I can get it going with some calibration discussion.
Does anyone know the difference between TV Brightness (not plain ol' "Brightness") and Backlight? It seems like you should just keep TV Brightness on "Brighter" and then change the backlight down to your viewing preference. Especially since I think the TV Brightness setting stays the same over all modes, so you would want it high for HDR viewing.
Also, what is everyone doing with the values below 50% on the iPQ app? Apparently the app doesn't calibrate those values. Also, I think it's best to keep the color space setting on AUTO.
