Displays Vid Card with high enough refresh rate for 64-inch screen?

I can disply my Apple MacBook Pro on my 64-inch TV screen. But the MB Pro has refresh only to 60 Hz. On the big screen this causes very noticeable flicker. What computer box or video card would I need to produce a disply on 64-inch at high enough refresh rate? (not sure what will be high enough). (Am using HDMI of course).

Thanks very much for any help! :)

60Hz is the standard for pretty much all displays so yeah, check your connections, cables, display drivers and software.

p.s. physical screen size is irrelevant, it's the resolution that matters.

For starters, if this is a macbook pro, you cant change any components on it. Depending on which version it is, it probably has an NVidia card inside. If your getting a flicker using the HDMI cord, you need to go into NVidia Control Panel and change the settings to match the monitor/TV. I dont have my NVidia laptop near me at the moment so I cant check where it is off the top of my head, but thats where you need to start.
