VGA to SCART adapter

[cobito]

Hello. I am looking for an adapter to connect a computer that only has a VGA output to a television that only has SCART and S-VIDEO inputs. I have seen that there are adapter cables, but I don't think they will work because I don't see it as logical to output a PAL signal directly through there.

Do these cables really work? If not, what would be the best option?

Thank you.

Of course it works, without any problem, they are analog signals and it is practically direct (see image: http://www.retrovicio.org/ficheros/tutorial/142/vga2euro.gif). You will have to send a resolution compatible with the TV, if it is a CRT not very old (it is understood to have euroconector) it will normally accept progressive (480p).

In the end, the issue is much more complex than it seems.

The VGA to SCART cable does not work with a CRT TV because you have to set the horizontal scan frequency to a specific value that does not match the standards of computer monitors, you have to get a frequency of 25Hz and you have to modify some more parameters of the signal. In total, you need a Radeon from the 7500 series onwards, which I do not have since the laptop has an Intel GMA950 that does not allow many configurations. In this thread the process is explained.

Passive cables are actually designed to be used in LCDs, projectors and other modern equipment, but not in CRT TVs.

So, I bought an active converter for about 14€ on eBay. Let's see if I don't have too many problems.

I remember that there used to be an option for TV output in the usual graphics, even the Wii had it connected with an adapter cable to use with TFT and it was passive… Look at it well, just in case you have a simple solution.

If it doesn't give you an option, you can manually make the output you need with an app like this: clever technologies - products - clever freeware - Home to DTDCalculator or any other to do overscan that works with intel. Because the graphics should be completely capable of outputting the resolution you need via VGA, the problem is that the driver doesn't give you the option, but for that there are applications, I haven't messed around with CRTs for a long time, I used to use rivatuner. Look for the refresh parameters and values that the CRT needs and create the profile that your TV accepts.

And anyway, PAL is 50hz but you can try NTSC at 60, 55 or 50, which is an easy option to modify. Also check if it supports progressive and if not, try with a resolution in betweenlace. The VGA output allows all that adjustment because it is designed for CRTs not for flat screens, of course, over the years those adjustments have been lost because they are no longer used, before the euroconnector they even had svideo output to connect to TVs (which was of very poor quality).
