To perform these tests, we use a high-speed camera that shoots at 1000 frames per second. Analyzing the video frame-by-frame allows us to observe the exact time it takes to go from a zero-percent signal to a 100% white field.
The pattern generator is placed at the base of the monitor so our camera can capture the precise moment its front-panel LED lights up, indicating that a video signal is being received by the monitor. With this camera placement, we can easily see how long it takes to fully display a pattern after pressing the button on the generator’s remote. This testing methodology allows for accurate and repeatable results when comparing panels.
Here’s a shot of our test setup. Click on the photo to enlarge.
The brighter section of the camera’s screen is what actually appears in the video. You can see the lights of the pattern generator in the bottom of the viewfinder. We flash the pattern on and off five times and average the results.
Here’s the screen draw result.

The 50L7300U has a Game mode, which, as you’ll see below, is necessary. The screen draw time is the same regardless of picture mode. The 240 Hz refresh rate is responsible for that first-place finish. Remember that this is an IPS panel. The only faster screen we’ve tested is the Asus VG248Q, and that TN-based display completed our black-to-white test in only seven milliseconds.
Here is the lag result in the Game mode.

We'd call this a fair result among HDTVs, but it won’t match any computer monitor we’ve tested. And the other picture modes are even slower. In Movie, we recorded a total lag time of 135 ms. Of course, most gamers employing this display will use a console, which is limited to 60 Hz. While the 240 Hz refresh rate reduces motion blur and judder artifacts, players with speedy reaction times will find noticeable input lag in their gameplay.

"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!
