NVIDIA recently started supporting FreeSync! But can I connect over Thunderbolt? (RTX 2080/ LG UB88-B)

Jan 9, 2019
My new build is still in boxes till after my exams next week (If I can restrict myself till then). I think I have everything figured out, and I already posted some questions about my build here before I decided to order: http://www.tomshardware.co.uk/answers/id-3869106/general-gaming-build-black.html . I bought everything new, except for the monitor that I already had to dock my Surface pro 4.

Recently I stumbled upon an article about Nvidia now supporting FreeSync with its latest driver for the 10xx and 20xx GPU's: https://www.pcworld.com/article/3333637/components-graphics/nvidia-driver-freesync-monitor-support-geforce-graphics-cards.html. Different sources allready confirmed that unlike some FreeSync monitor's, the Nvidia cards will only work over Displayport (as is the case with NVidia's Gsync) and not over HDMI. However, since my Surface docking station is allready taking up the one displayport I have on my monitor (https://www.coolblue.be/en/product/785657/lg-34ub88-b.html#product-specifications), I was wondering If i can connect my RTX 2080 with the thunderbolt cable and if FreeSync will then work?

I already read the FreeSync it is a hit or miss with monitors not approved my nVidia, but most seem to work fine over displayport after manually activating gSync/FreeSync . I was just wondering if connecting with thunderbolt is going to give me less chance of it working, so I can decide on what cable to order.

Also in general I am confused about which is the better connection method from my GPU to my screen?
