Yes, 8890 systems are available with UXGA - Page 7

laclasse you will see 16 boxes across by 16 boxes down. Within each box is a colour gradient. If your system does 16M colours the colour within each box will appear as a totally smooth transition. Again don't look too long your eyes will start seeing things.

If you have a lower spec screen you will start to see smaller boxes of one colour within the larger boxes. I tried on a 64K colour screen and it is quite noticable. A 262K screen will require a bit closer inspection.

As to who installs the LCD's it is Clevo according to the people I have emailed at Sager. When I first went hunting for the data sheets on the LCD's, Sagers reps indicated that the LCD's are fitted by Clevo then shipped to Sager. I agree it sux not having exact specs on something so important.

Ok, here goes.

8890 16.1? SXGA+ ??? ???


Fill in the blanks guys.

I think they did offer at least 2 different UXGA screens on the 8887.

Jeff

crap, how do I get spaces in there?

8890 16" SXGA = 25 msec

Whats different about desktop LCDs that are at 16 and 20ms and Laptop LCDs? What stops them from taking one of the thin desktop models and adapting it to the Laptop?

Jeff

I was referring to where Adam said "I believe all the Sager screens are 262K colors." Linky. I thought it was in this thread, my mistake. Sager sells the 8890, ergo the 8890 LCD is NOT 16M, QED.

Whilst I don't mean to contradict what Adam said, the specification I have for the 8890 LCD and the PNG file say otherwise. I don't know if Adam's statement is based on any in depth research he did or if it is an asumption (after all his words were "I believe all the Sager screens are 262K colors" not "I know this to be a fact because I have the data sheets and have tested them").

As to response times, there was some comments about the desktop LCD's dynamically dropping colour depth to achieve the higher repsonse times. I have not really done any indepth comparison between desktop LCD's and notebook LCD's response times and associated electronics so I can't offer any hard facts right now.

I have an 8887 with the UXGA.

I first looked at the PNG file on my desktop in True Color 24-bit mode and noticed smooth evenly distributed gradients. I then swithed my desktop to High Color 16-bit mode and noticed that each box got 32 gridlines.

I repeated this test on my 8887 in Highest (32 bit) and Medium (16 bit) with pretty much the same results with one exception.

When I compared the destop in 24-bit to the laptop in 32 bit mode, I observered the first (upper left) box. On the desktop the gradient is a smooth transition in both axes and diagonally. On the laptop the transition from blue to red is more abrupt at about the 20% from the top horizontal.

I also went to my display control panel and selected the advanced display properties then picked the "Color" tab with the ATI logo. I was able to move this "band" horizontally when I adjusted the color-curve set to red (vertically for blue), but was never able to make it blend smooth as the desktop. Another interesting thing I noticed was that when I went all the way to the lower right box on the PNG (green and yellow), then adjusted the "green", this box stayed fixed and all the others changed.

My desktop lacks these controls (82815 Intel on a dell box).

Does this attribute to the more vivid colors on my desktop? I find that my UXGA screen appears to have a "washed out" look. Is this less prevalent on the SXGA screen? I briefly saw a presentation of a powerbook at comp usa and was impressed by the display. Is this the same as the SXGA screen?

I noticed the same thing with my UXGA 8887 screen. My 8890 SXGA screen is so vivid & sharp that it makes my 21" Sony Trinitron desktop(Radeon 9800 Pro) system looked somewhat washed out.

Have you tried adjusting your brightness and contrast settings to obtain a more vibrant image?

I gather from all of the above that the 16.1 UXGA may be 16M colors. However, there are techniques that can be used to approximate 16M colors using a native 6bit LCD. Possibly, the 16.1 UXGA uses one of these, and that is the cause of the minor aberrations.

On the UXGA display, if you adjust the gamma setting to 0.75 (which is the setting Sager ships from the factory with an OS preload) from 1.00 in the ATI Color tab, it corrects the display to appearing as it should by default with appropriate color richness / contrast.

On my 8887 it doesnt. Yeah, it makes it darker and helps bring the pinks back to reds, but then go into any FPS game..impossible to see. What should be shadows are black and what should be bright is a dimly lit room.

Common problem with ATI cards: games play too dark. I recommend installing rage3dtweak from www.rage3d.com and make use of its per game contrast/brightness/gamma settings. That'll let you use the right settings for both games and desktop. Enjoy.

Yeah, thats a cool util.

Ive been playing with this thing since I got it. Even when I have the brightness and gamma set as close as possible to say, an external crt, the colors are so far off its not even funny. Greens are more brown - reds are pale. The only thing I can say good about my LCD is that even at 1600 res, the text looks good and is readable. The whites are pretty good for an LCD too.
