Sharp LL-191A-B: 16ms Response Time for 19'' LCDsby Kristopher Kubicki on May 18, 2004 12:01 AM EST

ConstructionOur Sharp 191A looks very different from any other LCD that we have seen to date. It feels particularly refreshing, considering that the last several LCDs we have reviewed all have very similar designs. Off the bat, the first thing we noticed was a lack of DVI interface on this monitor. This is unfortunate, but perhaps Sharp can still provide good performance even with this obvious deficiency.
Aside from the two included modest 1 watt speakers, there are not many frills on this LCD. In fact, we found the speakers for this LCD extremely poor. They are difficult to hear and do not provide any sort of DSP. Using the forward headphone jack is also not suggested; there was a severely noticeable loss in signal quality. However, we buy an LCD monitor from which to see things not to hear.

There are two items that catch our eye immediately: 16ms response time and 33W working power consumption. Power consumption is considerably lower than our Samsung 193P from last month. The 16ms response time will be the large determining factor in whether or not this LCD is game worthy. Since our sample did not have a DVI connection, the LL-191A already has one major strike against it (serious gamers need only be reminded that the majority of GeForce 6800 cards are showing up without analog 15 pin D-sub connectors, and for a reason). In previous reviews, we have shown that gray-to-gray response time is much more important for die hard gamers than TrTf response time, which is listed in the specification above.
The listed brightness of 220 nits seems low, considering most of the LCDs that we have reviewed in the last 18 months have been 250 nits (or higher). However, a quick visual inspection reveals that the brightness seems about on par with our Dell 2001FP. Our Dell 2001FP is capable of a UXGA signal, whereas the LL-191A is only capable of SXGA (1280x1024).
The quality of our 191A was very good. We found no imperfections in the panel; no dead pixels or subpixels. Again, much like our Samsung 193P, production techniques seems strong enough at this point to assure very high yield rates on a 1280x1024 panel.
