I am selling a Plugable UD-3900PDH. I used this previously for a triple monitor setup, and I'm selling it as part of a decluttering effort. For those familiar with Plugable products, or who understand them, how about it? Everything in the photos is included: - UD-3900PDH unit - AC adapter No box or accessories. *DisplayLink device driver or application installation is required. *I cannot answer questions about the purchase date, as this is a used item. *Please be aware that returns are not accepted after the receipt evaluation. *As this is a used item, there may be stains, discoloration, dullness, scratches, and scuffs. Please understand.
