Off-axis image quality is super-important in any large-screen HDTV. Since only one person can sit in the center seat, everyone else on the couch is forced to watch at an angle. While most manufacturers claim large viewing angles of 170 degrees or more, 45 degrees is realistic to us. Given a 50-inch LCD panel viewed at eight feet, getting four people in front of it is probably a practical limit if everyone wants a decent picture.
With that said, the 50L7300U looks pretty good at the edge of our 45-degree cone. There is almost no reduction in brightness and the color shift is limited to medium brightness levels only. We see a slight green hue in the 30- to 50-percent bars of the side-to-side view. This is a great TV for family viewing. A larger screen would be even better, and Toshiba obliges by offering sizes up to 65 inches in the L7300U model line.
Screen Uniformity: Luminance
To measure screen uniformity, zero-percent and 100-percent full-field patterns are used, and nine points are sampled. In a change from previous reviews, we’re now comparing the results to other monitors we’ve measured. First, we establish a baseline measurement at the center of each screen. Then the surrounding eight points are measured and their values expressed as a percentage of the baseline, either above or below. This number gets averaged. It is important to remember that we only test the review sample each vendor sends us. Other examples of the same monitor can measure differently in this metric.
First up is black field uniformity.

One of the negative traits of early model LED-lit HDTVs was poor black field uniformity. It was pretty easy to see hotspots at the edges and corners of the screen. Modern panels largely minimize this flaw. The 50L7300U looks fantastic displaying a black field pattern. There are no visible hotspots; just a nice uniform tone.
Here’s the white field measurement.

Again, we get a pretty good number. But it doesn’t tell the whole story. Aside from the center measurement, the other eight values are within 10 cd/m2 of one another. That’s impressive for any LCD panel, large or small. Only a slight hotspot at the center keeps the 50L7300U from acing this test. And it’s a barely visible flaw at worst.
Screen Uniformity: Color
To measure color uniformity, we display an 80-percent white field and measure the Delta E error of the same nine points on the screen. Then we simply subtract the lowest value from the highest to arrive at the result. A smaller number means a display is more uniform. Any value below three means a variation that is invisible to the naked eye.

The outcome is once again excellent. Planar's submission is a freak of nature. Any screen measuring less than three percent deviation will show no color uniformity flaws.

"Using the same settings on both Game and Movie, via OCD-levels of 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. And for reference,"Standard" seems to be about the same as Game and/or PC except that the backlight @ 42 seems to equal Game/PC's backlight @ 50."
For reference, CNET seemed to have assumed that the the "Movie" preset was the best when reviewing the L2300U (which is the same as the L1350U but in a different color) and then went and criticized the TV for having poor contrast and black levels. I just want to make sure Tom's doesn't make the same mistake in the future.

This also means that your calibration settings are most likely incorrect for Game mode.
It's important to note that CNET made the same mistake by calibrating via the "Movie" preset when reviewing the L2300U (which is the same as the L1350U but in a different color) and then went and criticized the TV for having poor contrast and black levels.
We did not assume that Movie mode produced the best contrast, we measured every mode to determine which was the best starting point for calibration. Our black level measurements take into account the full rendering of detail down to the lowest brightness steps. It's easy to drop the brightness control and measure a better black level but detail will be crushed. In the game mode, we couldn't get any better black levels than movie when you take detail into account. Check out the article where we talk about the use of dynamic contrast. That will give you a pretty good idea where the balance is between contrast and detail. Remember also that Game mode does not have the accurate color gamut or flat grayscale and gamma tracking possible in Movie.
When referring to forum posts, a statement like "via OCD-levels of eye-balling" means that the writer is expressing an opinion, not facts arrived at by science. We suggest taking information like that with a grain of salt.
And yes, our calibration settings would be incorrect in Game mode.

Christian did a great job, no issue with the article...just curious why (of all things) a random Toshiba TV gets the Tom's wax n' wash. Obviously, my whining can be attributed to an overabundance of first-world-white girl problems.
Lastly, I did try to talk to Gabe about HL3...but apparently im no longer allowed to attempt contact after mailing him 3 of my fingers with a note written in blood and tears, asking:
"Can you count to three now?"
We're working with Vizio to get samples of their new 4K screens. In the meantime, we have a Toshiba 4K HDTV arriving next week. Samsung is also looking good for future reviews. Definitely stay tuned!
