Use of univeral remote or code for Supra Tv and...

Question

Hi , my original remote control for Supra TV(ST29k22b) is broken .
I have a universal remote (Olympia - URC-22B25).
Can someone pls explain how to sync this new remote to my TV.
Also for some reason i cannot see the full pictire on the TV, all the edges of the pictures are like cut off or merged inside the TV.

Pls feedback.
Thanks
