Custom Resolution Utility (CRU)

[lureb74]

Hello everybody!

I think anyone here would like to OVERclock its own monitor! Well, I'm trying to do so as well, but I also trying to UNDERclock it!

I'm a cinema addicted, trying to achieve fluid video motion on a PC-monitor and PC-projector based systems, so my limitations are the 60hz-59hz-50hz @1920x1080 for my monitor ViewSonic VG2427, and the 60hz-59hz-50hz @1280x720 (progressive) plus 30hz-29hz-25hz @1920x1080 (interlaced) for my projector Epson EMP-TW620.

I'm playing my movies with MPC-HC plus FFDSHOW (audio and video filters), ReClock (for changing audio-video speed according to the actual monitor vertical refresh rate) and MadVR renderer.

With this software I already obtained very high quality results with perfectly fluid motion, specially with projector at 25hz interlaced (INCREDIBLE cinema-like experience for a system that costs less than €1000)... BUT movies are playing at 25fps instead of the original 24fps (actually 23,976) speed. This is called PAL SpeedUp, required because movies at 24fps STUTTERING when played on monitors with vertical hz different than a multiple of the original fps. PAL SpeedUp results, yes, in a fluid motion, but also you have the movie playing around 4% faster (and audio tones sound higher).

So, I tryed the CRU utility for achieving 72hz or 48hz progressive, or 24hz interlaced on my projector, with theese results:

Monitor VG2427
- at 72hz (tried many adjustments) the image is flickering with digital noise fussing around the screen... unusable!
- at 48hz (precisely 47.985hz) seems more stable, so I'm pretty happy!

Projector EMP-TW620
- at 48hz (precisely 47.953hz, very close to 23.976) seems stable, BUT projection is scaled to 720p (and still stutters, don't know why...)
- at 24hz (with CRU setted to 1920x1080@48hz interlaced) it results on a hyper saturated image and refresh have horizontal frequence of vibrations that goes up... I tried many variables on refresh and manual rates, but the result is still very bad!

Can anyone help me with any suggestion, may be with CRU manual settings?

Thank you, and sorry for the long post!
