Hyundai L90D+
Hyundai announced the release of 17” LCD screen with 10 and then 8 ms response times before summer s2004. Six month later we are still waiting for this screen. In the end Hyundai seems to have cancelled their fast 17” to release a new L90D+ (notice the “+” close to the D) equipped with an 8 ms panel.
This panel manufactured by Samsung is also included in the excellent 913N tested further in this article.
Ergonomics 
Even if this screen is equipped with a fast panel, and unlike its rivals, the L90D+ also has high ergonomics. The screen is vertically adjustable, it has an internal power supply, a pivot mode (very useful for image editing, typing long texts and surfing on Internet) AND it has two video inputs one analogical and one numerical. Amongst fast screens it is the only one and we appreciate the effort.
Color qualityThe screen white level is 196 cd/m², and the black 0,29 cd/m², and its contrast ratio is 677 : 1. This screen is brighter than a CRT but remains correct compared to the other flat screens.
Quite logically the L90D+ was also very accurate for color displays as the two following graphic shows.
How to interpret the graph ? The X axis is 0 to 100, where 0 is black and 100 is white.
When Delta E > 3, the desired colors is noticeably different from the one on the screen.
When 1 < Delta E < 2 colors are accurate. When Delta E < 1 the result is perfect.
Like many other screen the L90D+ color spectrum has nothing to be ashamed of compared to the CRT Mitsubishi. TN LCD screens can’t be considered as the worse panels for color display. The result is perfect here!
However like the Samsung 913N this screens’ viewing angles are lower than the average TN screen.
Games
Test with the L90D+ confirm our earlier tests with the 913N, the Samsung 8 ms panel is the fastest panel on the market. Compared to fast AU Optronics and LG-Philips panels, afterglow is reduced. And you really need to be allergic to LCD screens quality no to use it to play.
However, afterglow is still present. Very few of you will see it but it still higher than with a CRT screen.
InterpolationWe say it again, this screen should only be used with its native resolution.
We already noticed it with the Belinea 10 17 35 (a 17” LCD screen equipped with the same panel technology), the Samsung 913N and with this screen. Quality is barely good enough in 1024 x 768, and result below is very disappointing. If you want to have a better image in the game lower progressively graphic details until the perfect fluidity, but don’t reduce the resolution.
Movie
This screen ergonomics is satisfying, and the price also is. It is very reactive (it is the best LCD screen so far). We could hope that it would be perfect for everything…but it isn’t. TN panel as usual only knows 260 K colors extended to 16.2 M thanks to the dithering. This trick might work with games but with movies and color scale sit doesn’t. We usually see a strong “twinckling” effect, pixels moving apparently randomly (fortunately in restricted areas). It is a rather unpleasant up to 2 meter distance. After 2m this effect disappears.
Stil from two meter you need to be exactly in front of the computer. As mentioned earlier, the L90D+ viewing angles are lower than average: from 45° on the side, colors change.
VerdictTested later than the 913N, the L90D+ will however be available sooner than the Samsung (which will be available for most countries in number in January). The L90D+ is also cheaper and has better ergonomics. This screen has two inputs, analogical and numerical. It doesn’t change the picture or color quality, or the afterglow but at least you are able to choose. So this screen finally has a slightly better grade than its competitor. However do not get too excited as we know that only a few units will be available in the next two months so everyone might not be able to get one.
