LG filed 1 patent in 1 category: Hardware (1). The filing covers display technology for gaming monitors that support multiple Adaptive-Sync refresh rate ranges.
The patent describes a system where the GPU selects the appropriate frame range based on matching the maximum refresh rate to the chosen video timing, while the monitor adjusts its overdrive settings for each specific range advertised in its EDID data.
LG's single Hardware patent tackles a coordination problem between gaming monitors and Graphics cards when multiple Adaptive-Sync ranges are available. The invention establishes a matching rule that tells the GPU which frame range to use by comparing the selected video timing's frame rate against the maximum refresh rate advertised for each range in the monitor's DisplayID descriptors. The monitor must then optimize its pixel overdrive separately for each declared range rather than tuning it only for the highest refresh rate, preventing situations where the display operates at a lower refresh than the one its overdrive compensation was calibrated for. The patent ties this approach to specific descriptor structures that communicate buffered and non-buffered ranges along with flicker tolerance parameters in the first 6 bytes of each descriptor block.
