way of getting Touchscreen to work https://github.com/Xiashangning/IPTSDaemon

On Surface Pro 5 Kaby Lake HD620 (i5) Ventura 13.6.1./Opencore 0.9.7 internal display stays black and I only get display through the display port. Based on the discussion of this issue, it appears that no solution has been found even after three years of attempts. It seems unlikely that a solution will be found. Numerous suggestions and recommendations from developers and other Hackintosh enthusiasts were presented on SURFACE but none of them proved to be helpful.

Ventura 13.6.1 was working just fine until I connected an external monitor to it for the first time. Now, when I try to turn on the tablet, the screen remains black unless I plug in the mini-DP cable to connect the external monitor. I have tried changing the data with all the options in the DeviceProperties section PciRoot(0x0)/Pci(0x,0x0), but it hasn't helped. Also, the system loading freezes at the halfway point of the boot bar, so I returned to the initial working version when the system loads in couple with an external monitor. I am confused because I cannot understand how connecting an external monitor could affect turning on the backlight tablet's screen after the system has finished loading and opening the window of the tablet desktop. The screen does not turn on without a connection to an external monitor, and it turns off if I disconnect the external monitor. I suspect there may be some problem with backlight-related functions. I am planning to add some boot arguments in the NVRAM OpenCore section related to backlight, but it will be challenging for me since I am not very knowledgeable in the area.
