Custom Resolution "Overclock"

post #1 of 5
Thread Starter 
I have a Benq XL2420T which is specified for 1920x1080 at 120hz.
With Nvidia Custom Resolution Utility i can enter 1920x1080 up to 129hz which is as far as it works.

This is the exact timing stuff (i dont understand a word here):


I want to know if that will possibly harm the monitor in any way.

Well I run my monitor at 120hz which is exactly the double of what it is rated for. No issues what so ever. Been doing this with mild overclocks for years on my monitors, and never any issues. It's as safe as it can be really. But running over spec is always a risk.

I would set to manual, and then put polarity to negative on both, this reduces screen tearing wink.gif

129hz on your XL2420T? --

Make sure you do the frameskipping test: www.testufo.com/frameskipping
I saw my BENQ XL2411T frameskipping when I try to push it out of spec.

Also, why not try LightBoost instead of overclocking your monitor? It makes a much bigger motion fluidity improvement. View www.testufo.com/photo while turning ON/OFF LightBoost using ToastyX Strobelight.

These are my current settings at 130hz:


Some Results:









I've used LightBoost and it is a little bit too dark picture imo.
But i will give it a try again.
Wonder if i could use 130hz with lightboost...

thx and greets

If only one square is showing, your camera exposure is less than 1/130sec...

You need to use a longer camera exposure, preferably 1/5 or 1/10sec.
Try lowering the ISO (e.g. down to 80) and then change the Exposure compensation upwards.
You can also dim the monitor's brightness, to force the camera to decide to take longer exposures.
Can you try again until you see multiple squares highlighted, like this:
