I want to play games like civ that are better played using mouse controls via the touch pads, so I want to use the steam deck as a controller. But the screen is a little too small and some games don’t have good ui scaling so I want to be able to play on the TV. What’s the best/easiest/cheapest way I can play on the TV while still using the steam deck as a controller? I have a Vizio tv that doesn’t support steam link but does support casting. Thanks!
Not what you’re asking for, but another option is to use a DualShock 4 controller which also supports touchpad (which can be divided in left/right if you want). I’ve found a pretty decent amount of community support and often use the touchpad (or gyro) for mouse games, though it’s not quite as comfortable as the Steam Deck .
(I’m sure Dualsense 5 works just as well but I can only speak to Dualshock 4, which you can find for the cost of a HDMI cable online).
