System: Win 10 Battery or AC: Both Model: ASUS ZenBook Pro 15 UX580GD Frequency of occurrence: N/A Reset OS: N/A Screenshot or video: N/A ======================== Detailed description： I have the above model with the FHD screen but I was thinking to upgrade it with the 4K one. Can please provide with details how I could find the correct model/type? I'm in Australia so any recommendation for here will be highly appreciated. I'm thinking also to upgrade the webcam. The current webcam is very low quality for a premium product. Is such an upgrade possible? How to identify the correct model/type?
