Hi Acer,
Environment: The B326HUL monitor is connected via the Dual-link DVI cable that came with the monitor. It is connected to a "EVGA 512-P3-N973-TR GeForce 9800 GT 512MB 256-bit GDDR3 PCI Express" card. It is displaying at the recommended 2560x1440 reslution.
Currently the monitor is seen by Device Manager as "Generic PnP Monitor" using Microsoft 6/21/2006 driver v6.2.9200. So I downloaded your "Monitor_Acer_1.0_W8x64W8x86W7x64W7x86_A.zip" driver for that monitor running on Win8 64bit.
When I try to install that driver via the inf file, I get:
Install Error (dialog box) : "A problem was encountered attempting to add the driver to the store."
I also tried to install the driver via Device Manager via updaing the Generic PnP monitor, and also deleting that generic monitor and doing an "Install Legacy" device where I pointed the install directly at the inf.
Can you please verify that this driver is actually valid for the Win8 64bit environment?
Regards . . .
