After installing the 1.19 BIOS the external Acer X233H flat panel (1920 x 1080) is horribly unstable. I used it instead of the T400s LCD via a docking station. The Acer display is unusable - it appears to get and lose synchonisation every few milliseconds. It is always like this during boot and after windows 7 x64 comes up.
Once booted if I go to the T400s LCD, and back to the Acer it will usually settle down. The BIOS readme states the BIOS fixes some external display problems, but it seems to have caused others.
There does not appear to be a way to back off to the older BIOS. Is that correct? No older BIOS files were visible on the downloads page. I also tried to reinstall 1.19 just in case, but the clever utility says I already have it and stops there.

Funny. I could reproduce this every time yesterday after installing 1.19 (perhaps 10-20 reboots included), but after being powered off for 12 hours it works fine on restart this morning.
I am using the VGA port via the docking station. The T400s LCD was always fine...didn't try it direct off the T400s VGA.
Problem closed unless it resurfaces, and I'll repost if it does.
