Considerations & Notes

• Because it's hybrid, the keyboard port is PS/2 — USB keyboards may not work without adapter, depending on device compatibility.
• Audio switching may introduce some delay or limitation depending on speaker/microphone setup.
• Bus power is sufficient for most setups, but very long setups or weak ports may cause issues.
• Resolution limit at 2048×1536 — not ideal for ultra high‑res displays beyond that.
