⚠️ Things to Watch Out For
🚫 Mini DisplayPort ≠ Micro HDMI or USB-C—don’t confuse formats
🧪 Some cables are passive—device must support HDMI output natively
📉 Audio may not transmit on older Macs—check system settings
🧯 Cable length affects signal quality—keep under 3 meters for 4K
🛠️ Not bidirectional—only Mini DP → HDMI, not the reverse
 
🛠️ Quick Tips for Beginners
🧠 Identify Mini DisplayPort by its rectangular shape (~7mm wide)
🔄 Always plug Mini DP into the source and HDMI into the display
🧼 Clean ports gently—dust can cause flickering or dropouts
🏷️ Label clearly—Mini DP looks similar to Thunderbolt 1/2
🎨 Use active adapters for high-res or audio-critical setups
