TV signal via Serial Port

[M4rkpj]

Is it possible to get a decent TV picture via 9-pin socket? as my screen has this socket and so does my freeview box.
Will the picture be better than through scart connector?
The screen is Panasonic TH37-PW7 and Box is ALBA DV3
Thank you for your help.

This connector is for service only (for example, a firmware update). and can't be used for TV signal.
