How to use a TV as a second monitor

 Yes, I know TVs are plug-and-play, but you are not getting the best experience from it. First, open your Display Settings, and drag your TV to the proper place. And then, select your monitor, and then click on Advanced display settings. Now, click on XX.XXXX Hz (where X is the numbers). Now instead of that, you should choose the highest non-interlaced option. And on your TV, turn on Game Mode. Now, exit this menu, and click on XXX% (X is still the numbers). Now, click on all of them until you find the one you want. And then your mouse should work better, your second monitor should be faster, and your second monitor will look better! My TV is to the right of my laptop, it uses 60Hz, and I use 125%.
