idle Posted August 3, 2021 Share Posted August 3, 2021 Hi everyone! Another successful Big Sur installation! Dell Latitude 3510, Core i5-10210U, 16Gb DDR4-2666, Intel UHD 620, Big Sur 11.5.1, Dell U2718Q 4K + Docking Station Dell WD19 130w What works: Built-in screen Wi-Fi (due to the use of AirportItlwm.kext, but it is unstable, quite often loses connection and work only at 2.4 GHz) USB 3.0 ports USB-C port Keyboard Sound to built-in speakers Touchpad (reacts to pressing from the left and right as pressing the right mouse button, does not perceive scrolling with two fingers at the same time) HDMI up to 4K resolution (It is strange that in the window about the system, the graphics processor is defined as Intel UHD Graphics 617, although in fact it is Intel UHD Graphics 620 that is installed in this processor.) Handoff What does not work: USB-C DisplayPort Microphone Built-in Camera Jack 3.5 (the sound in the headphones rattles) Help me get what didn't work ... PS config2.plist - the image output works in the maximum resolution 2560x1440 (HDMI, USB-C) config.plist - output in 3840x2160 resolution works, but only via HDMI, there is no image through a monitor connected via USB-C.
