Below you'll find the settings I found best for viewing the Toshiba 50L2300U 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 Movie mode was the most accurate prior to calibration, but it was still pretty terrible, with a severely minus-blue grayscale and light gamma.

The first decision I made, as usual with Toshiba, was what DynalIght setting to use. I settled on Low since it provided the best balance of shadow detail and black levels. High produced even deeper black levels, but shadows were much too dark and gamma also suffered severely.

Grayscale calibration went better than expected given the simple gain-only controls; of course if I has bias/cut controls as well it would have been better. The CMS also worked well to get all of the colors to respectable error levels, with the non unusual exception of blue, for which the controls had no cure.

I also experienced an unprecedented strange anomaly when measuring gamma. The measurements in the CalMan report (1.97) were significantly different than what I measured in a standard 10-point grayscale run (2.2). I can't explain it, but I trust the chart's results more so that's what I ended up reporting in the Geek Box.

Movie preset has worse contrast & black levels
by NintendoManiac64 / November 7, 2013 7:36 AM PST

Assuming that the 39" L1350U is the same as the 39" L2300U other than the bezel color and that said 39" models display the same quality of image as the 50" models, I believe I know why you guys found the black levels to be too grey

On my 39L1350U, I just discovered that the "Movie" preset has considerably worse contrast and black levels than all the others. Using your calibrated settings, via eye-balling I found that Game and/or PC modes (which look identical) have similar white levels with backlight @ 50 compared to Movie's backlight @ 68. By comparison Movie's backlight setting had to be set to 40 just to get black levels similar to Game and/or PC with backlight @ 50.


Note that I tested this with DynaLight set to both "Low" and "Off"

Calibration
by skipnyc / February 3, 2014 7:00 PM PST

Two questions, first off I own this T.V. and I think it's really great... All my friends love it. Over all, the picture is beautiful, am I going to worry about some shadows in a movie, that fly by in seconds, Not at all.

Why couldn't all these setting be made to the "Standard" mode? Do you have to chose Movie Mode to use these Calibration Settings?

Also, you stated "I found best for viewing the Toshiba 50L2300U in a dim room via the HDMI input." What does that mean? Dim room via the HDMI input?
