Can I connect my TV to CPU through RS 232c cable as a monitor?

Answer:

if your tv have a vga or dvi port then yes. A lot of newer tv's are coming near them.



Otherwise, you'll have to use a standard video out (RCA) cable. This precincts the resolution to 640x480. It looks like crap on the tv.
RS232C is a serial port, so the answer as asked is no. There is a video cable (S-?) that will permit you go out of the computer within the TV aux input.
