Portable Monitor Connection Checker
Check MacBook and USB-C monitor setups before you buy
About Portable Monitor Connection Checker
Free, no-signup checker for MacBook Air M3/M4 and portable monitor setups. Pick one or two displays to get a plan for lid position, video cables, and monitor power, or use manual mode for other laptops. It separates USB-C connector shape from actual video support, cites official sources, and returns “unknown” when evidence is incomplete. WorkChoose maintains it; not every combination was bench-tested, and linked comparison pages may use Amazon US affiliate links.
