C64 Maxi into Commodore 1702 Monitor

Yes I'd assume so. There's just about every other combination of video output dongle out there, and cheap too. Right now I use a VGA to HDMI dongle to hook my desktop computer up to a large flat screen tv, and I also use a dongle that does the reverse of that, converting the HDMI output of my raspberry pi or C64 mini to a VGA flat screen monitor. Both of which were only $10 a piece on Amazon. I just had to plug the audio output of the dongle into a set of desktop computer speakers because the monitor has none.

What you'll want is a dongle that converts HDMI to S-Video, which is what the output on a Commodore 64 was for best quality, and is also what that input is on that monitor. It's just not using a standard S-Video input connector. Then you'll need a cable adapter for taking a standard S-Video output of the dongle connector and adapting it to the individual inputs on that monitor which I think people sell, or you could easily build one. I think 8 Bit Guy talked about building one in a video once. People use this adapter cable so they can plug things like VCRs or DVD players that use S-Video into Commodore monitors.

People always get confused about the output of a C64. It had three. RF, composite, and S-Video. It always irked me when I'd see people mistakenly hook a C64 up to a good monitor using composite instead of S-Video. Why go through the trouble of using an expensive monitor and then plugging in the C64 using a cable with lower video quality? The C64 was one of the first computers or even consoles to use S-Video before it was even widely known or used in home entertainment equipment . In fact it may have been the first computer or console to use S-Video?
