DVI-D to HDMI adapter, supports dual link for high-resolution output. Purchased used over 15 years ago and intended to use it with a PowerBook, but it never happened. I don't have an environment to test it, so its functionality is unconfirmed. Since it's old, I cannot guarantee its operation. - Type: DVI to HDMI Adapter - Connector A: DVI-D (Dual Link) - Connector B: HDMI Type A Please purchase only if you understand the above. Instant purchase is OK. Thank you for looking.
