Custom Resolution Utility (CRU)

2. Is 2001 the lowest you can go? What might be happening is 2001 is rounding up to 2002 and causing it to pass the 360 MHz limit. I recommend multiples of 8 for horizontal values. You should be able to get 2000 or lower by reducing the horizontal front porch and/or sync width if the monitor can handle that.

3. Maybe there's a 400 vertical back porch limit with EDID overrides. Try raising the vertical front porch and/or sync width to reach 1500.

Thank you for the reply, ToastyX,

The hardware itself supports 6 and 8 bit color as I've seen many other people with Nvidia cards and Benq monitors talk about the 6 and 8 bit options in the past, with screenshots. I've just never seen them talk about it on *laptops.*; very few people care about using desktop monitors on laptops and even fewer care about custom resolutions, with issues like Optimus not being able to be disabled in the past.


My laptop's monitor has a 6 and 8 bit selector on it. Just the Benq gets locked to 8 bit. This absolutely does not happen to Desktop Nvidia GPU's.

Optimus is disabled. The MSI GT72VR has optimus and the intel iGPU disabled so that Gsync will always be available. Optimus can not be enabled on this series.

I know there's a bug happening (I talked to Chief blur buster about it before contacting you), because when the Benq is plugged into mini displayport on the laptop, the "Advanced adapter settings" page will NOT load at all.

Your CRU editor will not allow me to go below 2001 on the horizontal total. It turns red. It's not that big of a deal because I can use the NVCP to create a custom 120hz resolution with 2001 HT, 1498 VT but other Nvidia users told me that there are some issues they had when doing VT tweaks on the NVCP that went away when using your excellent editor.

*EDIT*
Just hooked the Benq through HDMI.
Same problem.
With BOTH displayport AND HDMI:
the "windows display properties resolution box" was GREYED OUT And unselectable. And you could sometimes cause some sort of exception error by toggling monitors.

And advanced adapter settings (or advanced display settings, whatever it was called) didn't open. Only way to change resolution was with the NVCP.

On the old laptop (with a GeForce 570m), with the Benq hooked up, everything worked perfectly. 6/8 bit depth, resolution switching, advanced properties, etc.. But that was also in windows 7.

so I don't know if this is a windows 10 issue or a Nvidia driver issue, because this should definitely not be happening.
