Surprised no one’s brought up displays yet since it’s such a key part of the setup. You can have the best launch monitor in the world, but if your screen isn’t dialed in, the whole thing just doesn’t feel right. When I started building my sim, I jumped the gun and bought an LG 32GP850-B — a 32" QHD gaming monitor with great color, brightness, and a 165Hz refresh rate. I thought, hey, big screen, high performance, should work fine. But I quickly realized that it’s not at all suited for golf sim use. These monitors are made for close-up desk gaming, not for full-swing environments. It couldn’t replicate the scale or feel of a real shot, and obviously you can’t hit real balls into it. I ended up switching to a BenQ LK936ST projector paired with a SIG10 impact screen from Shop Indoor Golf, and that completely transformed the experience. Short throw, 4K resolution, bright enough to handle ambient light, and the screen can take full shots without any issue. It's the kind of setup that actually makes it feel like you’re standing on a tee box.
