Source2Maker product pagelg.com/au/monitors/ultragear-gaming/52g930b-bRead 14 October 2026Feature text on the UK page: DisplayPort 2.1 delivers ultra high speed gaming at 240 Hz on a 52 inch screen. AU and ES pages: USB-C (Max. Resolution at Hz) 5120 x 2160@200Hz, with USB-C DP version 1.4 on the US spec sheet. Tom's Hardware found 240 Hz works over HDMI 2.1 and says USB-C is limited to 120 Hz, which conflicts with LG's 200 Hz claim, so the maker value is stored. Bit depth, chroma and DSC per mode are not stated. LG notes a compatible graphics card is needed for 240 Hz.11Owner's manualgscs-b2c.lge.com/open/downloadFileRead 14 October 2026Product Specification, Max Resolution: 5120 x 2160 at 240 Hz (HDMI / DisplayPort) and 5120 x 2160 at 200 Hz (USB-C). The timing tables list 5120 x 2160 up to 240.005 Hz on HDMI. The DisplayPort and USB-C tables mark the recommended 240 Hz timing for Input Compatibility Version 1.4 and 2.1, and say a graphics card with DSC is needed for the preferred timing and frequency. Bit depth and DSC per mode are not stated, so they are left out.13Reviewtomshardware.com/monitors/gaming-monitors/lg-ultragear-52g930b-52-inch-5k-gaming-monitor-review-extreme-in-every-respectRead 14 October 2026Page 1: to run full resolution at 240 Hz, you can use either DP or HDMI. USB-C is DisplayPort-compatible but limited to 120 Hz in this test, which conflicts with LG's 200 Hz claim. Test PC had an RTX 4090.

The US spec sheet adds generic VESA Adaptive Sync Yes. NVIDIA G-SYNC is listed as not supported. LG's UK page warns the model is not officially certified as NVIDIA G-SYNC Compatible and that a G-SYNC label may appear on some stands by labelling error, so gsync_compatible is not stored although Tom's Hardware's table says G-Sync Compatible.11Owner's manualgscs-b2c.lge.com/open/downloadFileRead 14 October 2026Adaptive-Sync/VRR: DisplayPort and USB-C use Adaptive-Sync, HDMI uses VRR.
