My laptop's display, driven by an Intel HD 4600 GPU supports refresh rates of 40 and 60Hz. I'd like to set a custom 48Hz display mode for watching movies, but the Intel Graphics control panel is not letting me do it. When I try to add a custom resolution, I get an error "bandwidth exceeded" if the refresh rate is not exactly 40Hz or 60Hz, even though there is enough bandwidth to display 1080p@60Hz, obviously, and 1080p@48Hz should require less. Anyone know how to either trick the software into letting me add the refresh rate, manually add refresh rates by editing the registry or configuration files?
