I can also confirm that the new firmware fixes the blank screen/no signal issue @ 60hz with my Nvidia 750Ti which is now running at YCbCr 4:4:4/60hz without a glitch. As before I could only get 4:2:0@60 from the HDMI port. Texts look terrible at 4:2:0 due to color halo/shade. They look much better now at 4:4:4/4:2:2. Everything is much snappier @60hz and no noticeable lag.

Angel, my Color Space is set to Auto and Gamma is 2.1.
