+Red King Subscriber² Posted November 27, 2020 Subscriber² Share Posted November 27, 2020 So my laptop has USB 3.0 Type-C with Display Port 1.2 support. With a Cable Matters USB C to DisplayPort Cable I'm getting 4K 60Hz output from that USB-C port. But alas a cable is not enough, better choice would be a dock with more ports and charging and stuff. I got this statement "1. Single Monitor Resolution: 4K@60Hz (for DisplayPort 1.4) or 4K@30Hz (for DisplayPort 1.2);" from https://www.amazon.com/Anker-Docking-PowerExpand-Charging-Ethernet/dp/B088F7SY6S Most docks seem to be either HDMI 4K/30Hz or DisplayLink which is not for multimedia / gaming. Am I searching wrong? Where are docks that offer 4K 60Hz over DP when using DP 1.2 USB-C? Link to comment Share on other sites More sharing options...
jasondefaoite Posted November 27, 2020 Share Posted November 27, 2020 This should help explain the issue ... https://www.bigmessowires.com/2019/05/19/explaining-4k-60hz-video-through-usb-c-hub/ If the dock uses USB3, it's not possible to have 4K60 on the displayport link, only 4K30. You need a dock which only uses USB2, which may impact other things like Ethernet if supported by the dock. Some options for 4K60 are in the link. +Red King 1 Share Link to comment Share on other sites More sharing options...

That's a bummer, but explains why most docks are meh. Any recommendation for a well built type-c dock with power delivery support with DP 1.2 and 1.4 support (without DisplayLink)? Recommendation on that site are for slim devices - I want a single magical brick that does everything. I have Type-C laptops ranging from USB 2.0 with PD to USB 3.0 without anything to USB 3.2 Gen 2 with PD and DP 1.4. Link to comment Share on other sites More sharing options...
