Dual Mode switches between 4K at 240 Hz and FHD at 480 Hz. Maker spec page Signal Frequency gives 48 to 240 Hz vertical for HDMI, USB-C and DisplayPort at native resolution. The manual says Frame Rate Boost enables up to 1920 x 1080 at 480 Hz, and its timing table lists 3840 x 2160 at 240 Hz and 1920 x 1080 at 480 Hz as accepted on HDMI and on DP and USB-C. Bit depth, chroma and DSC for HDMI and USB-C are not stated. The manual's Type-C Bandwidth setting limits USB 3.2 mode to 3840 x 2160 at 120 Hz, so the USB-C maxima need the other bandwidth setting. HDMI 4K at 240 Hz needs a signal beyond uncompressed 48 Gbps, so no DSC value is stored for it.
