RDP client version 6 and above have a maximum resolution of 4096 x 2048.
The RDP 5 and lower clients supported a maximum resolution of only 1600 x 1200 in a 4:3 ratio. RDP 6 client has been substantially improved from previous versions.
Monitor spanning has the following requirements:
- All monitors must use the same resolution. For example, two monitors using 1024 x 768 resolution can be spanned. But one monitor at 1024 x 768 and one monitor at 800 x 600 cannot be spanned.
- All monitors must be aligned horizontally (that is, side by side). There is currently no support for spanning multiple monitors vertically on the client system.
