    Re: TV Refresh rate not quite right

    How about constructing a different modeline with either with 'cvt' ot 'gtf':
    Code:
    cvt 1920 1080 60
    
    gtf 1920 1080 60
    Regards.

    I could not get any of the new modelines to work either...

    ..BUT.. Type the following in, and BAM, the TV comes alive!

    Code:
    xrandr --output HDMI1 --mode 1920x1080 --rate 60
    I have no idea why it is using the refresh rate called 59.9 by default? This has now set it to 60Hz and the screen works!

    Thanks for all your help

    Can we identify where the core fault lies in this case? If we can figure out what was going wrong, we can get it fixed for other people in future. Whenever I use the display configuration control it again overwrites the refresh rate and I now have to run a little script to fix it. Can we get this display program fixed so that the actual problem won't be seen again..?
