Why exactly is ATi considered be better at HDMI?

I plug my HDMI cable into the card, then into my TV. Those are the steps that I have to do. All the steps you list make absolutely no sense to me.

 

Connecting laptop running windows 10 to hdtv with hdmi

I'm not very tech savvy.

• I know how to run the HDMI cable between laptop and tv.
• I know how to set my tv to use correct HDMI port.

What I need to know is how I tell my laptop to recognize my tv and configure it to use my tv as a monitor.

Anyone that can tell me step by step how to do this in windows 10?

Thanks.

Thanks for all the help. Hooked up the HDMI cable, plugged tv back in, started laptop up, switched the tv to correct HDMI port and viola...there was my laptop start screen on my tv! Didn't have to do anything but make a few display
adjustments!

Thanks again, everyone.
