BenQ XL2420T (first version) over 129hz?

Talk about overclocking displays at a higher refresh rate. This includes homebrew, 165Hz, QNIX, Catleap, Overlord Tempest, SEIKI displays, certain HDTVs, and other overclockable displays.

BenQ XL2420T (first version) over 129hz?

Post by lost4468 » 17 Feb 2014, 03:23

I have one of the original XL2420Ts (not the 144hz ones) and I've been trying to overclock it, however I can only reach 129hz, if I go to 130hz then the display tells me I'm out of range. Is there a way to prevent it doing this? Using a GTX 680.

Edit:

Ok it seems sometimes 130hz works, other times it doesn't. On the odd occasion 131hz will work... But most of the time it gives an out of range error.

The "Out of Range" error is often not possible to override.

Try testing "Reduced", instead of "Automatic" or "GTF". This will reduce the sync/porch values and lower the dotclock at the same refresh rate, giving you more overclocking margin. This may or may not work, depending on whether the range error message triggers based on the dotclock or on the refresh rate.
