The XGS Sparkle Display DEFINED !!!!!

post #1 of 16
Thread Starter 
I just recieved my XPS via UPS today.... The Display is Lousy. Everything else seems fine.

I just tried upping the vibrance on my LG XPS Display - (I have the same feature on my Dell 8600 gforce GoFx 5650 Graphics card also made by Nvida) and YES this increases color intensity but it dosent eliminate the problem I am noticing on my XPS LG LCD....... The so called sparkle.......

You can see what the "Sparlkle" is all about when you examine the screen closley with a 10X loupe magnifier....
NONE OF THIS HAS ANYTHING TO DO WITH THE GLOSSY COATING ON THE SURFACE OF THE LCD. THAT IS ANOTHER ISSUE
When you examine an area that is supposed to be solid white, for example, on this LG screen you can see a band of all black pixels going across the screen horizontally above and below EACH ROW of white pixels. On my Dell 8600 (also a 1920 x 1200 WUXGA diaplay) there is no band of black pixels above and below each horizontal row of white pixels like there is on the XPS. So the Solid White areas on the 8600 display appear as sparkly greyish-white areas on the XPS (because they are mixing black and white pixels). The Square Pixel matrix on the 8600 displays colors more solidly. The extra bands of color on the XPS display causes the solid colors to appear "not so solid"......, Yes it gives it a sparkling effect. This ALSO AFFECTS text.

In short, it makes for a lousy Display.

I am studying this more as I write this - the whole problem with the XPS LG display (I havent seen the Samsung one yet) has to do with two things
1) The pixel shape (square vs. vertical bar)
2) The space (or lines) in between the individual pixels

All this becomes very apparent if you have a 10X loupe magnifier and "a frame of reference", that is - another display that "looks normal".

In my case, my normal display is the WUXGA 1920 x 1200 display on my Dell 8600 made by Sharp. On my 8600, the solid colors are all really solid, there is very little or no black lines or bars between rows of pixels and the pixels are all really square on the 8600 display, on the XPS display they are not square; they are short vertical bars.....

I wish I had a powerful enough closeup lens that I could document this in digital photographs..........

Maybe I can make some accurate drawings to illustrate the problem. I intend to let Dell know what is going on as well as everybody on this Forum.

What a mess....... I need a new display (or another computer - the Sony display made by Sharp)

Maybe i'm not as bitchy as some people. I think my LG is excellent, colors are bright, I don't see any "sparkle" and the thinnest amount of light leakage at the bottom, barley noticable to me. The leak seems to be more if you look down on the screen rather then tilting the screen back to look at it straight on.

The Digital Vibrance setting in the driver is off by default. Turn it up to low even low medium and turn the gaam down to abotu .88-.92 and it is a thing of beauty.

More Sparkles

So this "Sparkle" has to do with the Pixel shape...
Remember when the Sony "Trinitrons" first came out .....
They had a different pixel shape - A triad
Some displays showed colored pxels as a red-green-blue "triad", and some used red-green-blue bars......

Looking at my XGS (I mean XPS, of course) , I see that ALL the Colors look "GRAINY" (with the exception of Black) bacause of the way this LG display represents pixels on the screen....

thehappyman, can you verify which LCD you have for us?

I know the rep told you that you have an LG, but the reps are wrong more often than they're right. And I think Samsung is known to have a vertical subpixel structure like you're describing.

Maxrule - the LG display is very bright and I see no leakage on my new XPS, but the colors are not "SOLID"....

Hard to explain what I mean if you have never seen an LCD with SOLID colors, I guess the best way to describe it is colors with "NO GRAIN".......

On my new XPS every color, the whites in the windows, the blue in the title bar, every color is "Grainy".

BELIEVE ME, I WISH IT WERE OTHEREWISE............
I just dropped a pretty penney on this XPS and now I am going to have to do something about this.......

If you are happy with yours then I am happy for you.

To start, they are delivering me a new machine on monday with a Samsung display.... If that dosent look good then I will return the XPS and get the new Sony Equivalent.

Solid Colors make a big difference.....
You would have to see a display with solid colors to know what I am talking about - you should see my Dell 8600

Dellbert - No, I cannot verify at this point, tonight, which display model I have... It's 1:30 am here now and I have to crash..... (unless you know of a really easy way to do this check offline)

I just got this XPS today and it isnt "online" yet, so I cant download "powerstrip". And I dont want to mess with the XPS if I am going to have to return it. The rep. (High end Tech Support) said I had an LG and that they would be sending me a new machine by monday.

I wonder why they arent sending a tech out to replace the display as I have a rather customozed XPS (2.13 P770 w/2gig Ram 60gig 7200rpm Drive). I guess I had better call them tomorrow....

In the meantime I am going back down to Best Buy and examine the Sony 17" Xbrite they have there with my 10X Loupe and see what the pixel structure is on that display. As soon as I find out I will post to this forum. Have a nice night all

I just ask because people usually describe the Samsung as looking like it has a "mesh," and that sounds like what you're describing.

An easy off-line test is to adjust the brightness all the way down (Fn-down-arrow), and then back up. If the brightness doesn't change between settings 2-3, you have an LG.

Thanks for the information HappyMan. Let us know what you find out.
