A:Answer Me,
There are a lot of reviews on Best Buy for this Sharp 43 inch Roku TV, do not really understand your question.
I am using this TV as a 4k TV via a wired connection from my internet router, it can be connected via a wireless signal also.
I have my computer attached it is not an Intel/Microsoft 4K Netflix approved 4k capable system, but it is nice to use GIMP software in 4k for pixel level artwork.
