I don't have my sencore manual in front of me, but looks like it is verified above. I am on the phone to vdc today to check what they have. Someone said the vatp4 was out of stock, but it shows up on website.. will see if they have. They have confirmed 20wp4 which is a 19" used in the xm501 monitors (space invaders, stunt cycle, space zap...etc..). Broke the nexk on my stunt cycle moving it so getting one of those.. probably have to repro the screen stickers as well.
