⚠️ Things to Watch Out For
🚫 These converters are directional—not reversible
🔌 HDMI to VGA may need USB power depending on model
🔋 VGA to HDMI always needs USB power and audio input
📉 VGA signal quality degrades over long cables—keep under 25 ft
🧯 Cheap units may cause latency, scaling issues, or poor color fidelity
 
🛠️ Quick Tips for Beginners
🧠 Always check the direction before buying—HDMI → VGA ≠ VGA → HDMI
🔌 Power the converter via USB before use
🎧 For VGA → HDMI, plug audio into the converter—not the display
🧼 Clean VGA contacts—analog signals are sensitive to dust
🏷️ Label your adapters clearly to avoid mix-ups in multi-device setups
