I am able to drive 4 non-overlapped 1080 HD Tablo windows from my laptop to my 4K UHD home theater screen. On my 10’ (120") diagonal screen, each of these Tablo windows is a full 1080 res 60" diagonal image. I wish the Tablo app for the Roku would support this. I am now looking forward to March Madness, which would be even simpler to set up if supported directly by the Tablo app on my Roku!
I have asked Roku for this feature, but I don’t know who owns the Tablo client for the Roku…Tablo or Roku.
