I frequently use Remote Desktop to access my home iMac from my university campus (using a 13" MacBook with resolution 1280x800). The iMac has two displays, the built in 27" 2560x1440 display and an external 1920x1080 display. There are three issues:
- Scaling down the resolution makes everything small, or I have to do awkward/annoying panning. I typically only view the 1920x1080 display over Remote Desktop, but even then it's sub-optimal.
- Large displays require high bandwidth. This isn't an issue if I'm at a proper WiFi network such as my university campus, but occasionally I also use my phone's tethering connection.
- Everything I do over Remote Desktop can be seen in person on the real displays.
Proposed solution: Somehow create a "virtual" display that's 1280x800.
- It's the same resolution as my MacBook's screen, so it won't have to scale.
- It's smaller, and will therefore use less bandwidth.
- It won't be a physical display, so it won't be visible in person.
Now, is there any way to produce such a "virtual display"?
