Cant figure out why it will not extend to Samsung TV anymore. It tells me the the resolution is lower than 1024 x 768 and the Samsung is 1280 x 720? How do I tell the SP3 to use a higher resolution on the 2nd monitor? It is greyed out.
What model adapter and TV do you have?
Can you try hooking up the adapter to a different laptop and see if it works with the TV?
Can you try an alternate adapter like the MS surface brand with your Surface and see if that helps?
