Ok guys so I’m thinking about getting one of those LG OLED TVs that have g sync and 120hz.

I have a Gtx 1080, and even on modern GPUs they don’t have hdmi 2.


So how do I get it to run at 120hz when I only have hdmi 2.0b?
 
Assume you mean 2.2 in middle sentence?


My Titan Xp with DP 1.4

"Display Connectivity
Nvidia's Pascal generation products will receive a nice upgrade in terms of monitor connectivity. First off, the cards will get three DisplayPort connectors, one HDMI connector and a DVI connector. The days of Ultra High-resolution displays are here, Nvidia is adapting to it. The HDMI connector is HDMI 2.0 revision b which enables:

  • Transmission of High Dynamic Range (HDR) video
  • Bandwidth up to 18 Gbps
  • 4K@50/60 (2160p), which is 4 times the clarity of 1080p/60 video resolution
  • Up to 32 audio channels for a multi-dimensional immersive audio experience
DisplayPort wise compatibility has shifted upwards to DP 1.4 which provides 8.1 Gbps of bandwidth per lane and offers better color support using Display Stream Compression (DSC), a "visually lossless" form of compression that VESA says "enables up to 3:1 compression ratio." DisplayPort 1.4 can drive 60 Hz 8K displays and 120 Hz 4K displays with HDR "deep color." DP 1.4" also supports:

  • Forward Error Correction: FEC, which overlays the DSC 1.2 transport, addresses the transport error resiliency needed for compressed video transport to external displays.
  • HDR meta transport: HDR meta transport uses the “secondary data packet” transport inherent in the DisplayPort standard to provide support for the current CTA 861.3 standard, which is useful for DP to HDMI 2.0a protocol conversion, among other examples. It also offers a flexible metadata packet transport to support future dynamic HDR standards.
  • Expanded audio transport: This spec extension covers capabilities such as 32 audio channels, 1536kHz sample rate, and the inclusion of all known audio formats.

LG OLED now are HDMI 2.1 but not current GPU's

"It’s unclear exactly what you’ll need on the PC end, however."
