XL2420Z Vertical Total 1350 -> black screen

Hey,

I just got my XL2420Z and am setting everything up. When I tried to do the VT1350 trick and clicked "Test" (Nvidia) my screen went black and stayed black until I hit Ctrl + Alt + Del. Any ideas?

Also the tests on the homepage (alien, moving picture etc.) show 60Hz. Is that supposed to happen? I am pretty sure I am on 120 Hz, I can feel the mouse being way smoother :)

Cheers

Nvidia's software sometimes fails and just sticks to the applied setting which can or cannot work. The annoying thing is even after a reboot it will keep these settings. I have had to reinstall my drivers twice now because of this via safe mode since otherwise it is very hard to fix it. Maybe there is some config file of it but I dont know where.
You can usually also look at your osd of the monitor and find its current refresh rate mentioned somewhere dunno if benq also does this. This should be correct 100% of the time. Otherwise just fire up a game in which you can achieve said framerate and enable vsync.

1. First of all, you'll need ToastyX Pixel Clock Patcher for ability to apply this VT tricks: http://www.monitortests.com/forum/Threa ... ck-Patcher for NVIDIA or http://www.monitortests.com/forum/Threa ... ck-Patcher for AMD.

This is often caused by the Crosstalk setting being wrong. Try launching Strobe Utility and sliding Crosstalm to far left before setting up the VT1350 tweak.

This is usually the browser misreporting the refresh rate. See www.testufo.com/browser.html

Hello,

thanks for all the quick and helpful replies. With the crosstalk set to the left I was able to test and apply the custom resolution now :)

Chrome is up-to-date and in chrome://gpu everything is set up correctly. It also reports 120Hz there. I will try the test with another browser later.

Cheers
