ViewSonic VG2755 usb-c display problem

Hello,


My problem is that Macbook doesn't detect my ViewSonic display correctly when connected via usb C.

I have Macbook pro 2017 base model with two thunderbolt 3 ports with Catalina 10.15.5 installed. I'm using original apple thunderbolt 3 cable and also have Belkin usb c to usb c cable with power delivery up to 100w and 4k video enabled and both facing the same issue. Problem is when i connect Macbook to display it's sometimes work on first attempt and sometimes it must be cable reconnected from 5 to 20 times till detecting display. It is pretty annoying. I tried Lenovo Thinkpad x280 with thunderbolt 3 port , windows 10 installed with the same cables and both works flawlessly, display is connected on first attempt. Manually detect display with pressed option button and clicking to detect display in display setting doesn't work. I saw there are few posts facing the same issue and looks like there is no solution. Maybe display driver problem on mac os side? It's possible to open ticket directly for apple engineers responsible for display drivers for check the problem? Thank's for answers.

MacBook Pro 13″, macOS 10.15
