With a simple input like this:
cvt 1920 1080 60
cvt -r 1920 1080 60
it gives two modes with pixelclocks of 173 MHz and 138.5 MHz, respectively.
However, CEA-861 states that 1920×1080@60Hz mode should have a pixelclock of 148.5 MHz. My fullhd monitor happens to have been receiving exactly this frequency, as it shows in its on-screen menus.
Why is there such discrepancy and can the output of
cvt be trusted at all, for any other modes such as 1920×1200@60 or 2560×1600@120 ?
