A Guide to Choosing the Right 19" LCD Monitor - 7 Models Reviewed

Quantitative Analysis

Luminance

Brightness ranked as one of our most important display qualities. The largest mistake that we see people make when they buy a new LCD is to put their new, bright LCD in a dim or dark room (and as a result, turn the LCD down to 25% brightness). Not only is this terrible for your eyes, but it also offsets hues unnecessarily. A blue screen in a dark room doesn't look the same as a blue screen in a well lit one! Staring at your monitor shouldn't feel like staring into the sun. If you have plenty of ambient light around, you would be surprised on how much of a difference a 250 nit LCD looks compared to a 300 nit LCD.

Below, you can see a comparison of the brightness for each of our LCD monitors. All monitors are set to the maximum brightness level and this was maintained for the duration of the review. The blue bar represents the advertised luminance and the red bar indicates the measured.


Much to our surprise, the NuTech LCD actually performed brighter than what the AUO spec sheet would have us to believe.

Our Contrast Ratio

For all the bad things that we said about contrast ratios on the previous pages, don't let us mislead you. Contrast ratios are important; they just aren't measured on any sort of level playing field, since manufacturer A and manufacturer B will measure them differently in order to market their product better. We do not have equipment as sensitive as manufacturers to test our monitors, but if we tested them all with the same conditions, we will still show a meaningful distribution of our monitors.

Observed Contrast Ratio
	Highest Recorded	Lowest Recorded	Observed Contrast Ratio
BenQ FP931	256.4	3.6	71.2
Dell 2001FP	222.6	4.6	48.4
NuTech L921G	278.2	2.6	107.0
Planar PE191M	234.0	3.0	78.0
Samsung 193P	230.4	2.2	104.7
Samsung 910V	219.8	2.6	84.5
Sony SDM S94	233.8	3.0	77.9
ViewSonic Q190MB	261.8	2.6	100.7

As you can tell, things pretty much run the gamut here. We were very surprised to see the NuTech L921G showing up with the highest observed contrast ratio, but as you will note from our measurements, we were only able to measure within an accuracy of 2/10 candela per meter squared. As we get better testing equipment, we will continue to update the results of these LCD units that we bought for the lab in future reviews.
