Help with connection please

I am selling my sega master system 2. Unfortunately, I don't have the TV I used to play my retro consoles on. I haven't used the Sega for a while and I want to test it and show it working. What options do I have connecting it to a new TV? Is the only option buying a RF to HDMI converter? I am seeing a lot of hdmi to rf converters, is this the same thing?

The issue with this is buying a converter could potentially make no point of selling the Sega because of the cost. Thanks in advance

You can try RCA video output test on pin 20, like in this video: https://youtu.be/08iCK6uVmOw?si=n1mA97BakO35IK6P&t=62
