Sharp LL-191A-B: 16ms Response Time for 19'' LCDs

LG Philips LCD LM190E03
To no surprise to us, the Sharp LL-191A uses an LG Philips LCD panel. We say "no surprise" because thusfar, they have dominated the low response time LCD market with the LM201U04 panel found in every 16ms 20" LCD to date. This newest LG Philips LCD panel is not shown to be in mass production yet (at least according to their website), so it is probably safe to say that the LL-191A is the first production unit available.We have mentioned some other display modes in the past. AUO's modified TN mode powered the Hitachi CML174 LCD with a 16ms TrTf response time. This LCD had very similar polarization and viewing angles. Both the Hiatchi CML174 and the Sharp LL-191A use 6-bit LCD panels. This essentially means that each sub pixel can "twist" to 64 varying degrees, allowing 64 slightly different hues of that sub-pixel through. When you consider three subpixels capable of producing 64 hues each, we consider each pixel capable of producing 262,000 colors. Other displays, such as Samsung's 193P use 8-bit panels; they can produce 254 varying hues per subpixel (or 16.7M per pixel). We have more information about how an LCD substrate works here. The LM190E03 panel uses a dithering technique to simulate 16M colors, but it is not true 8-bit rendition.
Unusually, even though the LG Philips LCD website claims 250 cd/m2 luminesence, Sharp labels the monitor as only 220. As we show later in this review, this seems to be correct; adjusting the brightness too high washes color vibrance out of the image.

Unlike our last 6-bit LCD, the LL-191A does not use a Genesis controller (see also Dell 2001FP). Instead, Sharp uses a much different Myson chipset - the MTV312MV64. The Myson chip is fairly robust, since it can support four A/D channels (the LL-191A only uses 1 analog channel).

From the looks of the controller circuit board, there is no room to expand a digital interface on future models. However, since the Myson controller does support digital and analog channels, we may see a digital version of this LCD yet.

#10:How many 19" LCDs can you buy for 699 or less, and how many 20" LCDs can you buy for 1099 or less?

In the conclusion, the author writes that oen of the nagging features is the $699 USD price tag. Why is this a nagging feature? Dell's 1901FP is $719 USD and thier 2001FP it $1,045 USD. Are Dell's prices nagging features too? Are 19", 16ms LCDs usually cheaper?AlexWade - Tuesday, May 18, 2004 - link
I just got my LG 1910S with a S-IPS panel, and its great! Even though respons times are listed at 25 ms, I notice no ghosting in Far Cry at all! Although, the text is not as sharp as I like.Basse - Tuesday, May 18, 2004 - link
Nice review,On the 2nd page, Construction, there is a typo I believe. The header for the spec table says "Samsung LL-191A-B". Should be Sharp or...?

Good review. Dell seems to be much better though.To watch the mpegs.. just R click and do a "Save target as" and then open them up with Media player or whatever player you like to use that can watch .mpg's

tfranzese: Should work now.Mithan: it could be; after a few years of DVI only it becomes a strain for me to go back to d-sub. Then again, some people may not be able to tell the difference (in the same way that some people cannot tell the difference between 20FPS and 60FPS). It really depends on what your eye perceives as acceptable.

Kris, I don't think it's a codec problem, but here's what works...When I click the image I get sent to a new window with this url:

If I just paste this part into the browser I can download it just fine and watch it with no problem:

Just seems to be linked incorrectly or sent through a script incorrectly. Hope this is of help.

Only thing I ever noticed on my Dell 1801FP (or whatever the model is, I'm to lazy to look it up, but you get my point) is that the DVI appeared to have better color. Gaming however, I wouldn't be able to say - thing has always been good to me gaming on analog because I use a KVM that doesn't have DVI.Mithan - Tuesday, May 18, 2004 - link
No DVI cable? So what.I bought a Samsung 172x and put it side by side with my existing NEC LCD 1765 (great for games BTW) and guess what? The DVI cable gave me virtually no improvement that I could notice.
Maybe it had something to do with running my 9700 Pro in dual monitor config? Anyways, I doubt it.
DVI is nice to have but I think you guys make a lot more out of it than it is worth.

I will figure out whats wrong with them. they work for me but maybe i have an odd codec that makes them work (they are straight from my Sony DSC since thats the only thing i had for mpeg capture).Kristopher
