I have a 3rd generation iPad and I am trying to use it as a second display to my laptops. My idea is to expand the work area and to benefit from the retina resolution of the iPad to have several programs opened at once. However, I tried Air Display (which is said to be faster than iDisplay or other alternatives), but it is painfully slow on both laptops. I have a 13-inch white MacBook (Core 2 Duo 2.4 GHz, Intel GMA X3100 video card) and a 15-inch Sager (Core i7-2720QM, NVIDIA GT 540M / Intel HD 3000). My wi-fi router is a TP-Link 450Mbps Dual-Band Wireless N Gigabit Router TL-WR2543ND. How is your experience with these apps? Am I doing something wrong? Are the video cards in my laptops unable to handle the retina resolution of the iPad (even the NVIDIA GT 540M)? Or are these programs slow anyway, and I just won't be able to use them no matter what?
