ok download these
unzip both files to your desktop to find easier.
reboot computer in safe mode.
open the WinDWFlash program.
it will ask you what file you want to open, browse to your b7t9.cvt file
then it will flash it.
don't do anything while it's flashing.
after it's done reboot the computer and you should have a benq1620 B7T9 now.
now if you want you can update to the latest firmware
reboot in to safe mode again, but this time all you have to do is hit the .exe file inside the zip and it will update the firmware.
then reboot again.
woooooooooo after all that your done :bigsmile:
hope that helps.
yes anything over a 90 is good.
