Re: Sony VAIO laptop: wrong resolution after mobo replacement

Hi everyone,

I have a Sony VAIO PCG-GRT260G laptop. The motherboard has died
recently, so I replaced with the identical model (MBX-86), identical
revision, identical part number, but from a different model,
PCG-GRT270. Every other laptop component (including the NVidia GeForce
Go 5600 graphic card) is from the PCG-GRT260G (except for the
motherboard).

Everything in the laptop works perfectly fine, except for the display:
Windows XP will not allow the native PCG-GRT260G resolution of
1400x1050, sticking to the PCG-GRT270 1600x1200.

I tried re-flashing the BIOS, installing signed and unsigned Windows XP
drivers for a Viewsonic 1400x1050 LCD monitor, hacking up a custom
monitor .inf file for, using various Windows XP software packages out
there to dynamically change resolution - all to no avail. Windows
XP/NVidia driver will stick to the geometry reported by the
motherboard, and that's it.

Anyone has any ideas? I'm at my wits end and I am getting close to
ripping a perfectly good laptop apart and selling it for parts :).

There is a bank of dip switches on the MB that adjust the video for whatever version of LCD is supplied. Set those switches on the new MB to the same positions as on the original MB to restore the correct LCD resolution. If this does not work, then work through the switch settings according to a binary number sequence.
