One of the issues with PC gaming on a TV has always been the refresh rate and lack of variable refresh rate. Samsung has launched the Samsung Q90R QLED with a 120Hz refresh rate and AMD FreeSync, matching many gaming monitors, but if you prefer OLED then LG may be the way to go.
Previously, if you wanted G-Sync on your TV you had to go for one of the BFG Displays, which never really took off, and cost a fortune. However, back at CES NVIDIA promised more big-screen G-Sync-compatible displays.
LG is now enabling this functionality via a firmware update for their 2019 OLED TVs including the C9 and E9 series. There is no mention of the flagship W9 model being updated, though I would assume this will be at some point.
This functionality is possible thanks to the inclusion of HDMI 2.1 with features like variable refresh rate (VRR) and Auto Low Latency Mode (ALLM).
These are technically only G-Sync Compatible because they don't use NVIDIA's processors. So they work in a similar many to G-Sync on FreeSync displays.
The 2019 LG TVs are also future-proofed with the inclusion of eARC on the 2nd HDMI port.
In terms of HDR, LG still doesn't support HDR10+ but instead use Dolby Vision HDR
