Kodi with New LG TV

i am having an problem kodi on an new LG TV (model 43UH661V)

the problem is if the tv goes to standby or think there is no input being detected when i switch back on the display for kodi is enlarged only showing about 1/4 of what should be onscreen

i have to CTRL+ALT+DEL end task for kodi and relaunch, windows display is ok just kodi that is being displayed incorrectly.

i have looked at a few posts and hdmi-cec is off in tv settings

i have tried upgrading from kodi 15.1 to 16.1 but no change
