Hey,
Im trying to connect my old tv (toshiba bomba) to my laptop. The tv has only RCA ports so i connected it by a rca-vga cable to the laptop, but the laptop does not detect the tv as a monitor.
I tried this with another tv and another laptop, but still the same problem. got any ideas?

VGA to RCA adapter cables ONLY work if the GPU is capable of outputing an RCA signal over the VGA port. You have to manually set it up to do that, there's obviously no way it would be able to detect a TV connected by RCA.

The other option is a VGA to RCA CONVERTOR. This will be a powered device, not a cable, and modify the signal for the TV.

I have to ask... Why would you want to? if the TV only has RCA the picture is going to be horrifying for anything but a PowerPoint presentation

TV is a TOSHIBA 21S2M, Laptop is a win7-64bit hp dv6 pavilion.
I dont know the max resolution supported by the tv..

Well, how can i maunally set up my gpu to send rca signals over vga port? its complicated?
bottom line, ive heard from couple of sources that the video quality will not be good.. there is an other option for connecting my old tv to the laptop except buying an hdtv?

the quality is because of the TV... your laptop is probably higher result never mind quality. the RCA bit would be an output option in your driver. you'd have to check you manual its a rarely used feature, especially since modern cards wouldnt have a much use for it. And only some cards can do it
