Hi Lou

Thank you for the "brighter" capture !  ;) That confirm my question.

About the approach, I usualy fly with the ATC (FSX IFR mode), use the computer for the flight (LNAV) and when the ATC give me the instruction for the approach (n° of runway), I just do as you say :
"Select APP/DEPT, then select the runway ILS of intended landing. This will automatically set the correct ILS frequency."
And I double-check that the ILS frequency is the right one on the radio panel
And I triple-check on the HSI/ILS mode that the frequency is displaied.
As you can see on my screenshot, this seems to work as I am able to land automatically...

I take the question under a new angle : can I ask you what are the "manipulations" (check-list) to do in the cockpit to use/display the ILS ?
Perhaps that I have missed a step ?  

About the video card problem... actually... I have cheated !  ::)
It's not a video card problem, it's just the top of the pilot's seat that I have pulled back in order to show the whole instruments on the picture.  

In advance, thanks for your precious help  :)
