First thing that pops into my mind is resolution. The BIOS and splash screens are at low resolution but when XP loads, it raises/changes the resolution to something that the LCD won't display.
Boot up in safe mode, and change the resolution to something lower on your regular login and on administrator login and reboot.
Hey thanks for your response...but I don't understand how that would be the issue because my other LCD's work fine on these machines ... not to say I won't try...

I don't believe the display is for your model. Never seen that particular Samsung display in an 8XXX series notebook. If that is the case, it may work with the proper inverter, but it is unlikely. I've seen similar results from a display I was told came from and 8200 when in fact it came from an 2600 Inspiron. Fit right in and the connections were the same, but all I got out was garbage. The Samsung part number for 8XXX series notebooks is LTN150P2-L01, L02, L03. Any one of those should work with the correct inverter and cable.
What monitor driver are you using? If you are using a Dell specific driver, try using a "Default Monitor" driver. It is possible that your OS is trying to optimize the display output to a display that has features yours doesn't support.
You could also try booting the OS in "safe mode" to see if using a default VGA driver still has the same problems.
Yep, I know it's the LCD from a laptop that's giving you problems. From the pictures posted, first appearance is that the computer is trying to display 800x600 on that 1600x1200 screen.
Try booting up in safe mode and switching to all users on that computer and switching the resolution to 1600x1200 16bit color and then reboot.
I wish there was a way to list the resolutions of each user on a given xp install. I think one of them is set incorrectly and for some reason, xp is using that resolution as the default setting.
One question; have you tried other similar LCDs on that computer? If yes, what resolution is the screen at after booting up into windows?
It works good in DOS/BIOS, it runs through the XP installation (which runs in VGA mode), but when it boots to full OS (at high resolution) is "fails". This still could be either OS or hardware, but it looks lees like a hardware issue and more like an OS issue. If it were a video RAM issue, it could still work at the lower resolutions because you wouldn't be hitting the bad RAM on the video board.
I remember installing XP on my Latitude C840 (with the NVidea GForce-4) an dI used the native XP video drivers and could access the full 1600x1200 resolution on the LCD. I did later install the Dell drivers (and later other drivers) with no problems either. What drivers are you using in XP? The "native" XP drivers, or are you using Dell supplied drivers? I also seem to recall that Dell did ship some 8200's with GForce-2 video boards, so are you sure you have the right driver installed? I'm not sure what would happen if you forced a driver onto the system, and you had an older model of video adapter.
I might be tempted to boot into safe mode and "un-install" your video adapter, then re-boot and let XP come-up and re-detect it. That might resolve the problem by re-installing the driver (or instlling a new driver if XP doesn't think the right driver is loaded). You might try booting the system up with boot logging enabled. That might show something in the bootlog.txt file, but since it appears to be booting (just with corrupt video) I highly doubt that it will provide anything too useful here. If you have access to an external monitor, you could try connecting it. If you enable both LCD and CRT, you could then see the CRT and try adjusting the resolution downward until you find the point at which it will display properly on the LCD. If it is a resolution setting, it might be that the system is trying to use a resolution higher than 1600x1200, and that is causing your problem (although most LCD's I've used just go blank if you try to display in a mode the panel doesn't support.
Let me know where you get and I will see if I can think of anything else.

Oh ok I wasn't trying to downplay you , I just saw it strange that you said it couldn't handle high resolutions.
As far as safe mode, I only have one user on the machine, as it is a fresh windows xp install and I did what you said...no good...
Also, while the screen was divided (as in the picture) I uninstalled the Geforce driver and at 800x600 the screen was OK
To your question, I did the opposite
The 8200 that is is on is as follows
My primary laptop is an I 8100
2.2 Ghz
512 MB RAM
Nvidia Geforce 440 Go
Win XP Home
Another 8200 I have is
2.0 Ghz
512 MB RAM
Nvidia Geforce 440 Go
Win XP Pro
My primary laptop is an I 8100
1.2 Ghz
512 MB RAM
15 UltraSharp UXGA (not the same screen)
Nvidia Geforce 440 Go
Win XP Pro
I have tested the screen on all three and have the same issue... I have 3 Ultra Sharp UXGA screens and that is the only one acting in that way
"I have tested the screen on all three and have the same issue... I have 3 Ultra Sharp UXGA screens and that is the only one acting in that way
Thanks :-)"
Well, if you have 2 identical LCD screens and they act differently on the same computer, then it has to be the LCD that is bad and nothing to do with the computer.
Maybe I'm too tired, I couldn't find where you'd said that you'd tried 2 different LCDs on the same computer, just where you'd tried the same LCD on 2 different computers.

Did that... and it worked at 800x600 but when I upped the resolution it went crazy again

To make lower resolutions "stick", you have to change ALL users, including administrator, to that lower resolution.

Not sure if I even said that myself *yawns* heheh
but if the issue is the LCD...what could it be?
I was still thinking inverter board , but I dont want to spend $50 on a guess....
What do you think?:smileywink:
