![]() ![]() macOS does not have a method exposed to the user to change the output pixel format (except the new "High Dynamic Range" option - 10bpc is required for HDR). Some pixel formats are not supported by Intel or macOS or both. How wide of a resolution (a normal timing, not a scaled resolution) can you make in SwitchResX? 8192?īelow is a list of max pixel clocks for DisplayPort 1.2. I am referring to single cable displays (which use one DisplayPort signal), not dual link SST displays like the LG UltraFine 5K display (which use two DisplayPort signals - 2560x2880 each).įor confirmation evidence, we need timing info from SwitchResX showing pixel clock and active pixels of 5120 or a photo of the onscreen menu of the display showing 5120 width. Update: This is because my display is 4K - you need a display that has a timing in the EDID with width > 4096 to allow 5K SST. I did not get the same result with my Mac mini 2018 (newer Coffee Lake graphics). ![]() Looking at the code, it appears that only Kaby Lake and Coffee Lake were updated to support 5K SST. Update: Others have reported success with Coffee Lake graphics. ![]()
