Hello,
There is no such bug in V5.

If you flashed the firmware yourself or if you just bought the monitor, if you are using "Blur reduction" with a "Vertical Total 1500" or "VT 1350" tweak, you may wind up with a black screen if the Strobe Phase is higher than 049 (120hz) or 059 (100hz). To fix this, set the strobe phase to 000. This is because after a "recall/reset all", the strobe phase defaults to "100", as this is Benq's default for trying to reduce input lag by up to 1 frame (a high strobe phase doesn't work with Vertical Total tweaks). This is easy to fix.


1) power off (do NOT unplug; unlock codes only work after a "soft" power off, not AC power off).
2) hold button #4 for 5 seconds, then press the power button.
3) keep button #4 pressed until the screen appears. If you do *NOT* get the "Logo" window, you did it correct. If you did get the Benq/Zowie logo screen, you didn't do it correctly.

Then 4: press button #4 to enter the service menu and change the strobe phase.
