Your projector and PC determine how sharp and smooth the sim looks - especially on large impact screens in bright rooms. Golf bays favor short-throw and ultra-short-throw models that fill the screen from limited depth without blocking the swing path.
Short-throw and ultra-short-throw laser projectors from brands like BenQ and Epson are common picks, paired with a capable Windows PC for GSPro, E6, and manufacturer software. Measure lens-to-screen distance before you buy, and prefer physical alignment over heavy digital keystone for clarity.
Do not underspec the PC: large resolutions and detailed courses need GPU headroom, fast storage, and cooling that survives a closed media cabinet. Brightness should match how much ambient light your bay gets; a premium projector on a weak PC still feels laggy. Mount safely clear of driver swings and plan cable runs once.
