I believe it's because the > pixel clock of 148.35 is higher than the maximum of 135 Mhz.
Here are some links that may help. http://xtiming.sourceforge.net/cgi-bin/xtiming.pl http://gentoo-wiki.com/HOWTO_Xorg_HDTV What the pages say is that it can be difficult to get the timings correct and HDMI can be fussy about the ModeLines. One thing I noticed is: >>> (--) NVIDIA(0): SHARP HDMI (DFP-0) >>> (--) NVIDIA(0): SHARP HDMI (DFP-0): 135.0 MHz maximum pixel clock >>> (--) NVIDIA(0): SHARP HDMI (DFP-0): Internal Single Link TMDS >>> (II) NVIDIA(0): Mode Validation Overrides for SHARP HDMI (DFP-0): which means that nvidia driver thinks that you are connecting to a DFP (digital flat panel) as opposed to a TV. I'm wondering if a HDTV is a digital flat panel or a TV. I would guess that a DFP is correct, which means that the ModeLines will work. One of the howtos said that when starting X add "-- -logverbose 6" to that startx command line for more detailed information about why modlines are not being accepted.
