Below you'll find the settings I found best for viewing the TCL 48FS4610R in a dim room via the HDMI input. Your settings may vary depending on source, room conditions, and personal preference. Check out the Picture settings and calibration FAQ for more information.
Calibration notes: The Roku TV's controls are so sparse that a true calibration isn't possible. I was happy to note that its best preset for a home theater environment, Movie Mode with TV Brightness set at "Darker," was decent if not spectacular. The main issue was that default black level (the numeric Brightness control, not to be confused with the five-position "TV Brightness" switch) was way too bright. I reduced it as appropriate but kept most of the other controls untouched.
I did experiment with the various TV Brightness controls--they serve to override Backlight, making the overall image brighter or darker--in search of improved gamma, but after compensating for backlight level differences there wasn't much I could do. I also tried the Normal color temperature but it was far less accurate than Warm.
Colors are off quite a bit in their default settings, but I was able to get error levels more respectable by desaturating the image quite a bit. Cyan was the worst, and of course impossible to fix with the paltry controls.
