![]() Tried the disable/enable DP 1.2 solutions mentioned above, still had the same issue. Apple recommends updating firmware for the monitor but I couldn't find any. From what I can tell this is something of a known issue with this dell model and has something to do with DP 1.2 compatibility. The monitor would flicker intermittently connecting to the Macbook and sometimes not recognize entirely. I know I put into the correct input/output ports. Changing the monitor end to HDMI, which will require other cords, should resolve.įor those of you to whom the above solutions don't apply: And not a motherboard BIOS update feature through Windows Update.Different to my HP laptops.TL DR: Not sure, but seems like the flickering issue is specific to mini-DP (macbook) to DP (monitor), regardless of port and setting. And not a motherboard BIOS update feature through Windows Update.īe aware this "System Firmware" seen in Device Manager has been around since Windows 8.Īnd is NOT limited to just OEM devices (laptops) - Windows UEFI firmware update platform. BTW the Lenovo's BIOS (and drivers) are updated through Lenovo's Vantage software installed on the laptop. This is my Lenovo laptop, which shows 4 firmware updates in Device Manager with one of them having an issue (and needs to be addressed), and none of them matching the actual BIOS info.Īgain, none match the BIOS version as seen in System Information. ![]() Here's my "System Firmware" info for my main system (system specs system one). ![]() Nor has Windows ever update any BIOS on any of my system builds. ![]() With that, last night I manually updated my motherboard's BIOS from F9i to F9j and that info is NOT shown in the firmware tab, nor does it match the driver date, nor did it ever. Such device firmware typically works together with a device driver, allowing the OS to expose the device to OS-level services and applications.Īnyway, on both my custom built PC's with Gigabyte motherboards "System Firmware" is listed in Device Manager, so not just for OEM builds. System firmware is responsible for providing critical boot and runtime services to the system as a whole, and device firmware is associated with a particular device integrated into a system. There are two types of firmware that can be serviced via Windows: system firmware and device firmware. Overview of the UEFI firmware update platform ![]()
