Laptop display problems

Hi all,

I have a Sony VPCSE17FX laptop. It came with the AMD Radeon 6630M GPU, along with the Intel HD 3000 GPU built into the CPU.

Recently, it developed a grey vertical band across the LCD screen. I'm fairly certain it's not a Windows driver issue, as the band shows immediately upon startup (before it goes into Windows).

So I'm guessing that the GPU circuitry has gone bad? If that's the case, is it possible to reroute the video signal through the remaining GPU?

1. The first thing I need to know is which GPU is driving the LCD display.
2. After ascertaining the above, can I disable one GPU and use the other?

Thanks in advance.

It's much more likely a problem with the display itself. Connect an external monitor, and if all is fine there, it proves the display is bad.

I guess that's the other issue. If I connect an external monitor, I should be able to route the signal by hitting Fn-F5 keys simultaneously. But nothing happens...unless there is another trick to Sony laptops.

Right click an empty space on your desktop, select resolution, and then you should be able to select the monitors you want to use, and how (Duplicate, Extend, only use display 1 or 2, etc).

The problem can also be caused by a loose or damaged video cable. Of course to reseat the cable you have to partially disassemble the laptop by removing the power button bezel, and the keyboard.  Definitely not a driver issue if the issue occurs as the system is booted up, or in the bios.

you don't need to switch the displays with a key :  http://docs.esupport.sony.com/pc/VPCEG1_EH1_EJ1_EL1_series/EN/contents/02/07/04/04.html

so it looks like your video card has a problem; and this means  a new motherboard; sorry...
