VGA Switch for analogue I\O?

Hi,
I have a DB15->Scart cable that works properly @15Khz.

I'd want to buy a second cable and add a 1 input x 2 output DB15 switch in the chain, so I can go to 2 different CRTs @15Khz.

Would any VGA switch be ok? Would any consumer VGA-VGA cable be ok to go from MiSTer to the switch (no pin modification required and such)?

Thanks.

I have done this successfully — I’m sure there are variations in quality among the switchers, but it’s a pretty simple thing to build, so I assume most of them are fine.

Thank you! If there is no problem\risk involved with voltage and such, I'll try some VGA equipment, then report.

These are excellent: https://www.amazon.com/gp/product/B0881 ... =UTF8&th=1

Any cable should be ok as long as it is properly shielded. Otherwise you could have bad video quality.
