How do I enter this:

Screen refresh rate 75 Hz
Vertical refresh 79.976303317536 kHz
Pixel freq. 135.0 MHz


I can only select one of them, and then the other two settings correspond to the one that I have manually entered. I can't enter all three myself, unless there is a way that I'm not aware of.

EDIT: I have manually changed the Visible area, Front porch, Sync pulse and Back porch, and now it does adjust the Vertical refresh and Pixel frequency to the values that are mentioned in the manual. I'm rebooting then testing it.

EDIT 2: It doesn't work. I tried again with VGA and DVI and also the established resolution, but i still get the warning on the monitor OSD.

I just don't get it why does monitor work at 1280x1024@75Hz, but still keeps turning black after a while. It should either work or it just shouldn't. It's like the monitor is just teasing me with showing that it actually works and then turns black

I'll get the 144Hz monitor some day or even Korean 2560x1440 monitor and overclock it, but I wanted this monitor to last a bit more. The 75 Hz does make a difference over 60 Hz :/

You just need to get a different monitor, then. Sounds like firmware issues.

I know the Benq Z series monitors (and I believe the previous T series as well but do not quote me on that) do NOT support 85hz refresh rates UNLESS They are at native resolution. 1920x1080@85hz works (this isn't defined as a default refresh rate, it works if you do a custom and the OSD identifies it as 85hz) but any lower resolution at 85hz, e.g. 1024x768, 1280x1024, 1152x864@85hz all show "OUT OF RANGE!" on the OSD. Even in VGA/dsub. Yet you STILL see the screen perfectly anyway...you just can't enter the OSD although you can close the OOR error popup.

I thought this was a firmware bug too but the service manual has a "X" next to all of the 85hz refresh rates, which means not supported.
