Subjective Tests and Conclusion
 

A Word About Testing:

In everything we try and be fair, accurate and as objective as possible when it comes to testing hardware.  In the past, LCD reviews were done completely subjectively, but we have purchased some equipment that takes some of this out of the equation.  Take a look at our LCD Testing methodology over here to get a better idea of how we test LCDs.

We won't spend much time in the menu; it is pretty standard although a little stripped down in terms of contrast, color adjustments and the like.  The only real setting in the menu that will help you tweak your screen is the "Brightness" control.  Other notable options are the MagicBright settings as well as the USB or VGA selection.

Color Accuracy: 

We started things off by breaking out the LCD Spyder and finding out how well this unit is set up and how well it produces accurate color.  We did this using both the USB and VGA connections and the results were identical.

As you can see above, the color of the LD190 was pretty darn close to perfect and although the software created a new color profile for this display, I could hardly tell the difference between the calibrated and uncalibrated settings.  Once the test is done, you can choose before and after comparisons, and there was a slight difference.  The calibrated settings were slightly "warmer".

 

Contrast Ratio & Uniformity: 

With the display now showing "perfect", we proceeded to take our contrast readings.  As previously mentioned, the only setting available on the display was "brightness" and it ended up being set at 54%.  With this setting chosen and the display calibrated we set out to find the "real" contrast ratio of the LD190.

I know we may take some flak for the above results, but this contrast ratio is exactly what the consumer will see when the display is set up properly.  It doesn't come close to being 1000:1 and even when we maximize the contrast and brightness, we don't get much above 180:1.  Keep in mind that this display is still very nice, clear and doesn't burn your eyes with too much brightness.  Companies pad their specs, much like gamers pad their stats in their favorite online game.  It doesn't mean the product is bad, merely that specs are over-rated.

We use our luminance meter in a dark environment to measure brightness uniformity.  To measure brightness, we use a bright white screen and measure across the screen in a grid to get our readings.  The brightest spot is considered to be 100% and the blackest point (with a black screen) is considered to be reference 0%.  The other values are obtained by calculating the difference between the two.  The screen is often brightest near the center.

As you can see the backlight drops off in certain areas of the display, but never drops below 85% of the brightest point.  While that may sound like a lot, often other "premium" displays from other companies can vary as much as 30%.  The Samsung LD190 comes in with a maximum 15% variation.

On the last page we'll cover some real-world applications and see how it holds up playing movies as well as day-to-day tasks before we wrap things up.
