I recently got a Samsung S34E790 34" Ultrawide Monitor for my computer. I want to be able to watch TV using my HD antenna.I don't want the computer to have to be on all the time to watch television. Something capable of 4k resolution with HDMI and if possible capable of streaming media. I just started looking at Tuners but I am not sure exactly what I am looking for. Any suggestions on what to get would be helpful.

Thanks,
Dave
