Hi guys, what's up?

It's been a long time and the bilLABS site is still all messed up

. Someone should ask them for a job as webmaster...
After rechecking the old bilLABS monitor thread,
BILLABS 1024x768 monitor, seems clear you've got the 38 KHz standard "TruFlat" version, BL27CA1Q. Look in the thread, MikeQ was told the 50 KHz model was going to be BL27CB1P.
If all your problems are limited to your monitor not being able to do 1024x768 non interlaced, then it's all fine.
And about your monitor's Sub D15 cable pinout, if it's working right then it's like it should be. My own arcade monitor is missing pins 4 and 9. Look at any VGA pinout diagram and you'll see there's no problem with it.
Having missing/unused connections or pins is pretty common in almost every bus/connector. That doesn't mean they are bad!

How much did you paid for your unit?
Cheers
