created two actually 97220 & 97221 as I noticed that my 144Hz monitor 
could not set anything higher than 120Hz and that only on low resolution.

Almost made a third as my 3D TV that I think should be able to do 
1920x1080 in 120Hz to actually do 3D I'm not sure what it should 
actually report as valid resolutions.  now I get this from it.

HDMI-A-0 connected (normal left inverted right x axis y axis)
    1920x1080     50.00 +  60.00    59.94    24.00    23.98

should it not also handle plain 1920x1080x120 but there was so many 
different options that I'm not sure if the TV actually support that mode.
It is mentioned it does 120Hz in 3D but not that it can do it normally. 
but should it not be possible to simply drive it in 120HZ and just have 
normal images not designed for 3D ?? not sure ow that stuff is supposed 
to work. in windows10 at least the OS detects that the screen can handle 
3D do something like that exist under linux ?
