https://www.youtube.com/watch?v=burNkdZG0Bs&feature=emb_title gave me the best insight till now. Of course a test at prad.de or https://www.tftcentral.co.uk/ is way better. I always order these technical stuffs at Amazon. If it doesn't fit my personal needs I can return it without problems. But to be honest: I always like to test these things on my own if they fit my needs - I was let down by various tech-sites in the past.

I preordered the Samsung G9 and was curious about the same question. I got a reponse from the Samsung Swiss Social Media Team on Youtube. If you want to use 240HZ, you need DSC - only supported by NVIDIA 20XX generation and the latest AMD chip. With any other card (as I use 1080TI SLI) you can only reach 120HZ. The 2 DP inputs are just for 2 different sources and can't be combined. Seems we all may need an upgrade to the new NVIDIA 30XX generation.
