## Questions & Answers

**Q: I have a hp elitebook and its adaptor is giving 65w power. can i use this monitor type-c port as a power source?**
A: Yes but the computer will inform you that you are using a low power source and the laptop will charge slowly.

**Q: Can I split the screen using displays from 2 different systems?**
A: No.

**Q: is the the 34 inch ergo curved monitor have a UK plug and uae warrenty?**
A: Yes, it comes with a UK plug. I don't know anything about the warranty. Hope won't have to use it.

**Q: How does the stand mount on table? Any requirements like drilling screws, have a flat edge, etc.?**
A: It has a flat grabbing surface on top and a screw with a round holder on the bottom. Be mindful that the table surface should be about 2cm thick to properly grab and the table material sturdy enough to hold the monitor. Would advise against mounting a monitor on cheap table tops which are hollow or made of pressed wood chips.
When it comes to the mount itself, it's the best one I ever worked with.
