If you own a Nintendo Switch, you might want to check out the GENKI ShadowCast currently on Kickstarter. The ShadowCast is an easy way for you to use your Laptop screen to play your Nintendo Switch (Or PS5).
Simply connect GENKI ShadowCast to the HDMI out port of your console, connect the USB Type C cable to your laptop, launch the Genki Arcade app and you are good to go.
And the best part is that you can record your gameplay and even stream online. While it may not be at the same level as a professional grade capture card, it’s more than capable for most gameplay capturing needs while being much more flexible and easy to use across multiple platforms.
You can back the GENKI ShadowCast at Kickstarter now and receive it as a reward if you pledge $39. That’s a lot cheaper than most video capture card in the market.
Do note that this is a Kickstarter campaign. You should know the usual risks involving Kickstarter campaigns before you back the project. If you are not comfortable with the risks involved, then wait for the product to hit the market.
