I hooked a Dell laptop with 1 HDMI port to TV HDMI port. Set to show different windows on each screen. Added 2nd TV with HDMI splitter. I want to show different windows on laptop and each TV. Both TV's show same window. Laptop only identified 2 screens.... Laptop #1 and both TV's #2. How do I display 3 different things?? Laptop #1, TV1 #2 and TV2 #3?? Thanks!
