So I'll answer my own question for all the people that might buy this monitor or a similar model: Out of frustration, I ordered a new USB-C cable from Amazon with USB-C 3.2 4k specs. I just arrived and the monitor finally works over USB-C only. I just detatched the HDMI cable. DEAR DELL -Team: If you're already delivering the monitor with a USB-C cable, please make sure that it's of decent quality. I think other people would have just returned the monitor back and didn't fiddle with it. I wasted maybe 4-5 hours on problem-solving, testing it over HDMI, testing it with my iPad Pro etc. but not everyone has a hdmi cable at hand or another device to test it with. Like said before another person would just try it out with the boxed usb-c cable, see the screen not working/flickering and just return it back. This way you're losing customers and revenue. I'm a business owner myself and that's why I'm writing all this. Otherwise I wouldn't care much. But it's all good and it's all love
So I bought myself this S2422HZ and it works fine via HDMI and USB-C (Camera and Audio). I wanted to use only one single cable though. 1. Test was with my Laptop Huawei MateBook 16 (2021 model, USB-C 3.2 should be supported via the charging port). HDMI: Works fineCamera + Audio via USB-C (cable that came in the package): Works fine Picture via USB-C (cable that came in the package): Doesn't work, I get some screen flickering here and there and the monitor goes into standby mode 2. Test with iPad Pro 2023 via USB-C (cable that came in the package) - Screen works fine Any ideas? Should I order another USB-C cable and test it with it?
