UltraSharp^TM compared to CrystalView^TM and XBrite^TM

Thread Starter 
I've always hated the screens on laptops... until in a Fry's store, I saw the Fujitsu CrystalView and the Sony XBrite screens (and decided that the laptop which I purchase will have a good screen).

How does the Dell UltraSharp screen (ala i8600 15.4") compare to the XBrite and the CrystalView? (and, are these similar products from different companies, or are these completely incomparable screens...?)

Thanks!

I believe they are all trademarked names to describe a certain set of parameters an LCD screen must meet to be sold under that name. I KNOW that Dell's Ultrasharp are not made by Dell, they are screens made by Hitachi, Samsung, and Sharp. If the screens meet or beat certain paramaters, such as above a certain brightness, higher than a certain contrast ratio, a response time less then XXmilliseconds, and a viewing angle greater than XX degrees, then Dell will market them as Ultrasharp.

The same probably goes for Sony and Fijitsu. I think Sony makes their own screens but the quality should be similar to Dells, if not slightly better.

My brother has an Ultrasharp desktop display and it blows away the non-Ultrasharp Hitachi display we have on another one of our computers. BUT, my other brother has an LCD display he bought from Sams with specs similar to the Dell and looks every bit as good. So really, all these various names let you know you will be getting a very nice LCD display as opposed to those offered on some other laptops.

For what it's worth, the displays on Apple's G4 Powerbooks are very bit as good as the Dell Ultrasharps, et. al.

For reference, the Widescreens offered on Dell's i8600, i9100, XPS, D800 and M60 have a 300:1 contrast ratio, 35ms response time, and U50/D50/L65/R65 viewing angles.

This is with the exception of the old Hitachi WSXGA, but I have heard the new revision of the Hitachi WSXGA is now starting to ship which also meets those specs.

In addition to DELL-sakor1's specifications, Dell's wide screens have the luminance/brightness of 185 cd/m2 (nits).

The Dell Ultrasharps are good (using one now) but not in the same game as the Xbrite or Crystal View etc.

Ultrasharp is probably better than most laptop LCDs, but nothing even a little like the experience of a Sony or Fujitsu...those screens are really remarkable.

Specs won't do those screens justice. Standard LCD's are not in the same league.

The Crystal View is fundamentally different from other notebook LCDs. Its panel is a MVA panel rather than the TN panels of most other LCDs (Sony XBrite may also be a MVA, not sure though). This difference alone can be responsible for some increase in viewing angles, higher contrast and brightness, and faster response times. In addition to MVA, the Crystal View also meets certain other parameters (I believe Fujitsu refers to this as Premium MVA) namely a 600:1 contrast ratio and 350cd/m^2 brightness. The extra brightness may be due to the use of 2 fluroscent tubes instead of 1. (I know for sure that 2 fluroscent tubes are in XBrite, but not sure about Crystal View).

The larger GRT screens use 2, but the TR XBrite only uses 1 with a reduced number of LCD sheets. See this article:

I agree, the Dell screens are supurb..... but are still blown away by the XBrite and CrystalView. Of course you'll pay for that extra viewing goodness though
