“What is the spec of the DisplayPort 2.1 input - UHBR10, UHBR13.5, or UHBR20? I would like to know if I have to use display stream compression to push the monitor's max resolution of 5120x2160 and refresh rate 165Hz using 10-bit HDR.”

Hello there. We understand your inquiry about your LG 45GX950A-B’s DisplayPort 2.1 input. Your monitor’s single DisplayPort 2.1 connector is rated for UHBR13.5 (13.5 Gbps per lane, 54 Gbps total), not full UHBR20 bandwidth. To drive the panel at its maximum 5120 × 2160 resolution, 165 Hz, and 10-bit HDR, you’ll need Display Stream Compression (DSC), since the uncompressed data rate (~60.18 Gbps) exceeds the 54 Gbps link. Tip: Be sure to use a certified DisplayPort 2.1 UHBR13.5 cable and enable DSC support both on your graphics card’s driver panel and in the monitor’s OSD for the best, artifact-free performance. https://www.bestbuy.com/site/lg-ultragear-45-oled-dual-mode-5k2k-wuhd-165hz-wfhd-330hz-0-03ms-g-sync-freesync-premium-pro-gaming-monitor-black/6619492.p?skuId=6619492 If you need further assistance with setup or cable recommendations, please send us a private message on social media @LGUSSupport and our team will be more than happy to explore possible solutions.
