The connection from my macbook to my t.v. is delayed/slow I have my 2013 macbook connected to my brand new Sharp HD t.v. through an HDMI wire. I'm basically using the t.v. as a monitor.  It looks great.  The only rub is that there is a slight delay when I give a command to my computer and what shows up on the t.v. screen.

For example, the mouse will move a split second later on the t.v. than it does on the computer monitor.  It's a small thing that makes a big difference in operating the computer.  It makes for sluggish and more difficult work.  Not truly real time.

I've changed wires and got the most expensive "cinnamon" wire they had at Best Buy, which didn't make a difference. Any suggestions on how to tighten this up?

Thank you!

Check if your TV has a mode called PC mode or Game mode. TVs now a days perform some additional processing to the input signal to supposedly improve the picture quality. This, however, can add a bit of delay. Samsung TVs have a mode called Game mode which turns this off. I am not sure what it is called on Sharp TVs. If you cant find one, cycle through each video preset and try to find one which has no delay.

Additional info:
In case your TV doesn't have a game or PC mode, it may still allow you to modify the required settings manually. Search for something along the lines of 'Picture Noise Reduction', 'Motion Enhancer' or 'Skin Tone Enhancer' in the video settings and turn it off.
