Can I use my laptop as a second monitor?

Is it possible to make my laptop's screen act as a second monitor for my desktop computer?

Solution 1:

Here's an interesting freeware solution:

ZoneScreen

Solution 2:

To my knowledge, spacedesk is the best:

• No issues with unsigned drivers
• No issues with aero
• Free, at least current beta
• Supports either windows app, or any html-5 web browser as "client"
• Windows 10 / 8.1 / 8 / 7 (x86 and x64)

Cons: This tool (probably, just like all other today's tools) is unable to provide nice FPS together with high image resolution and color depth. Even if link speed itself is not the issue (e.g. if you have 1Gbps LAN connection) "motion smoothness" is still far from perfect. So, although this solution is suitable for tasks like office work, it is hardly suitable for video/gaming.

Solution 3:

Maxivista is a commercial software that lets you do this.
