More likely it’s what your display is doing to it, rather than the OSSC itself. It could be that it thinks 4x is a PC resolution so is changing colour space over what you normally have the display calibrated for? Just a shot in the dark.
Thanks Bucko – I”m going to do more testing with a wider range of tv’s and see what happens. I think I might be able to adjust some of the GAIN on the OSSC and see if it gets brighter. Also I will try the new .82 firmware which came out.
