Loading compiled TBS drivers, Breaks Video driver.

I have just installed ubuntu 24.04.2 to an Intel_ DH67GD MoBo... ( yes and old Mobo, but more than capable of running 4 video streams and more ) I can do all the updates/upgrade and bring everything up to current release.
And everything is good,.. and the display resolution is set to 1268 x 1024 or so,.. perfectly fine for running a displaying as my media player.
However, if I go through the process of compiling and loading the TBS drivers ( as per docs) for my TBS 6904 card,... I get the /dev/dvb/adaptor1,2,3,4 showing card drivers have all loaded fine, but the primary display is now only working in default mode,.. ie something around 800 x 600,.. to the point that a cmd window fills the screen.
If I try to reset the screen resolution, there are no alternative setting available,.. even though xrandr shows many setting potentially available.
I have tried several times,.. but each time the TBS drivers are loaded,.. the screen resolution 'breaks'.
I believe I may have a compiling issue with the new kernel, and associated video drivers,.. but this goes beyond my pay grade (and knowledge),.. is anyone able to spread some light,. and knowledge on my lack of...
Many tx

make dir DIR=../media
make stagingconfig
# echo "Disable RC/IR support"
sed -i -r 's/(^CONFIG.*_RC.*=)./\1n/g' v4l/.config
sed -i -r 's/(^CONFIG.*_IR.*=)./\1n/g' v4l/.config
make -j4
# echo "V4L drivers installing..."
