Hi Scott,

To be able to view a display in bright sunlight you want to be looking for an "E Ink Display"...

Example: The Amazon Kindle DX with a 9.7" display



$129 used at Amazon

Not sure if this Kindle DX, or any Kindle "E Ink display" reader would be able to link and display your T-5 setup, but it may be worth investigating. But for sure the display you need to view in bright sunlight has to be "E Ink Display"

Good Luck My Friend
