Sims Community has one guide that might help.
You can get 10 metre HDMI cables from Amazon that might help too.

I haven't tried the second one as I have read that there is a slight delay in reactions in game to clicks using Wi Fi from laptop to TV.

I have an Nvidia Shield but honestly, don't use it. Instead of asking here... You may be better off searching Google. Try YouTube videos as well. Go to the Nvidia website for the shield. I'm guessing not too many people here use or have an Nvidia Shield.

Yeah, I use Geforce to play WoW on my TV while it's running on my PC. There is a slight delay, so I make sure I'm not doing anything important. My living room TV is huge, so I wanted to try the sims on it, and have the full use of my PC versus my laptop. I've searched online, and most of the things I find state to use Steam to do it, which is fine, I got the game to come up on the TV doing that, but then couldn't get the mouse to move, so I was a bit stumped. I'm going to give it another go when my new mouse comes tomorrow. If I have to use the shield controller, I'm not even going to bother.
