I recently built my first rig and been using the hdmi cable that came with the MSI Optix G24C6 144hz monitor, which should be 1.4b. But now I remembered that the monitor is G-Sync compatible. Through googling I found out that majority prefers display port over hdmi but since I don’t have DP, I’m not exactly sure if it’s worth it (and hdmi 1.4b seems to support 144hrz anyway). What exactly does G-Sync do and should I get the DP for it?

Also, my gpu is AMD RX 5700, if that helps.
