U2725QE configure thunderbolt to use display port 1.4?
My laptop does not have thunderbolt support, but it accepts usb-c for power delivery and display port 1.4.
I tried connecting the thunderbolt port to the laptop usb-c using supplied cable, but it causes laptop to freeze when starting up.
Is there an option to configure the thunderbolt port to support display port 1.4?

Sounds like your laptop’s USB-C supports DisplayPort 1.4 but not Thunderbolt, which can cause compatibility issues with the monitor’s Thunderbolt port. Unfortunately, Thunderbolt ports usually can’t be manually switched to pure DisplayPort mode. You might want to try using a dedicated USB-C to DisplayPort cable or adapter instead, which often works better for video without Thunderbolt support. Also, check if there are any firmware updates for your monitor that might improve compatibility.
