Hello all, I am trying to connect my 2011 mini (2.5 GHz Intel Core i5 and AMD Radeon HD 6630M 256 MB GPU) to my 2015 Samsung 4K TV using HDMI. I know it will only go up to 1080p and that's ok. I tried connecting to different HDMI ports on the TV but to no avail; the computer doesn't even detect the presence of the TV. Currently there is a 1080p monitor connected to the computer via mini display port. Any suggestions / ideas how to get this to work? Thank you!
