Choosing the right dummy plug depends on your resolution needs, hardware support, and deployment scale. This guide breaks down key factors to help you make an informed decision.
Ensure the plug supports your GPU's maximum output. Most modern plugs handle 4K@60Hz which is sufficient for most tasks. For high-refresh gaming, look for models supporting 120Hz or higher.
Check if the default resolution matches your remote needs. Some models default to 1080p while others start at 1440p or 2160p.
Aluminum shells are preferred over plastic as they dissipate heat better. This is critical for 24/7 mining or server operations where overheating can cause instability.
Gold-plated connectors prevent corrosion and ensure reliable signal transmission over time. Look for units with sturdy construction.
Most plugs work across Windows, macOS, and Linux. However macOS sometimes needs specific emulators to detect virtual displays correctly. Check compatibility lists before buying.
Verify support for remote tools like RDP, VNC, or Parsec. Some plugins offer better performance for specific streaming applications.
Bulk packs like 3, 4, or 5 units often offer better value. They are ideal for server farms or home labs with multiple machines.
Single units might suffice for temporary testing. Consider your total deployment size before purchasing to save on long-term costs.
HDMI 2.0 supports 4K@60Hz. HDMI 2.1 allows for higher refresh rates and bandwidth. Ensure your GPU supports the version you need for 120Hz.
Older HDMI 1.4 plugs are cheaper but may not unlock full GPU power. Match the version to your hardware capabilities.
LED lights indicate connection status. This is useful for verifying if the GPU is active without remote access. It adds convenience for physical checks.
Some models lack LEDs to keep costs low. Decide if visual feedback is necessary for your use case.
Look for products with at least a one-year warranty. Some brands offer two years which shows confidence in durability. Check support contact options.
Quality support helps if you face compatibility issues. Reputable brands often provide clearer documentation.
Passive cooling via aluminum is standard. Active cooling is rare but useful for mining rigs. Ensure the design allows airflow around the device.
Overheating leads to disconnections. Prioritize units with proven heat dissipation features for continuous tasks.
Insert the dummy plug into the HDMI port of your computer. Ensure it is fully seated to guarantee connection detection. The device does not need external power.
