Others/Miscelleneous by SidneyWong @ 2007-11-12

20.1inch TFT Display with 1600x1200 resolution for less than $190, this LCD monitor provides both DVI and VGA connectors, built in power and 3-watt speaker. High resolutions LCD display in traditional/classic format is aimed at more serious users. Let´s see how this inexpensive unit stands up to the trusted Samsung 204B.

Performance

Performance:

Frankly, I have no idea how to evaluate monitors other than hooking them up to equipment that measures Color Space in sRGB or based on half a dozen similar standards; produce a few charts and graphs. I certainly have nothing against the approach; a scientific approach I always accept. Fortunately, no dead pixel on both of the monitors, something that the graphs don't show.

However, there is the human element involves for as long as we are dealing with senses, plus the fact that we don’t have the fancy equipment. My option is “testing with seat of my pants” in trusting my own eyes. With five LCDs sitting around me, I thought comparing images by capturing them with digital camera might do the job. After using the two monitors side by side for almost a week on a daily basis, I have no complains (serious complaint) against either one.

When it comes to presenting how my eyes sense the color images from those two monitors, the following photos were taken with my Canon camera after the monitors were calibrated under the same condition using Pantone "huey" calibrator tested previously. Instead of listing which of the two monitors the photos came from, I would leave it to you to make the decision. This is a $160 question, the price difference between the two monitors.

Comparing the photos, the difference of the two monitors could be subjective and subdue.


Response time: H20 25ms versus Samsung 5ms - Ghost Chasing

The tricky part, LCD response time is coming down drastically. It is now commonly found at 5ms or lower.

Using 3DMark03 and Canon EOS 20D set to 1/250 second shutter speed, let see if we could get the "ghost".

After taking almost 100 shots from 1/500, 1/250 and 1/60, there was not much difference. I would skip them and list two using 1/60 second below, you are not missing anything.

What the lens of camera captured was not what I could vision. As far as I am concerned the two monitors show similar effect in my eyes, no ghosting could be seen. Obviously, the camera lens disagrees. The slower H20 does show more trailing effect.

At the university we have 16ms and 25ms monitors and the difference kills me every time I browse forum. The article should talk about how useless it is to get anything lower than a 20" WS if you choose a TN panel and who IPS panels are good for (people who work with images)
