Custom Resolution Utility (CRU)

ToastyX:

How exactly is this possible?
This is a 1080p monitor...

Take a look at this screenshot...(it's 100hz refresh rate, not 60hz).



I got REALLY curious after going through the V4 firmware dump of the XL2720Z and seeing a bunch of resolutions in it that were higher than native.

So I had to do a lot of work but I figured out something:
The vertical total limits what the Benq can accept vertically. It can accept any vertical total up to 1502 (certain ranges under 1494 will give out of range errors).

I don't know about the horizontal. Masterotaku created a 60hz with a 2876 horizontal total to get a strobed VT working.

This is 100hz refresh rate btw. The screenshot says 60hz because the strobe pulse widths switch to 60hz whenever the Vertical Total (VT) is out of specification.

Note: I can't create a 60hz one. it just says "Out of range" with a black screen. Only the 100hz one works.

So did I just create scaler supersampling? Or a bad case of interpolated pixels? (I assume that AMD VSR/Nvidia DSR would look the exact same way?)

*edit* if toastyX is around.
60hz ="black screen Out of Range!"
61hz = works perfectly. What?

(occasionally when switching around from 61hz to 100hz, OSD thinks its a 720p and says 720p on OSD when its not)
