Question about LC-Power LC-M16-4K-UHD-P-OLED

I have created a support ticket for this at LC-Power. As mentioned above, the Surface Pen is supposed to work. After clarification with the technical department, they were unable to give me any further details. Due to the abundance of pens, they did not want to list them (2-3 that work would have been enough for me...). If anyone knows of other pens that work, please let me know. I'm still wondering :)

surface pen works pretty well :D has a little lag but works great...

We looked at the manufacturer's specifications as well as some tests and product presentations. Unfortunately, not even a stylus was used, so we have to assume that this is not possible.
