Matching an old monitor to a new computer often requires an adapter of some sort and occasionally a different cable. Most commonly needed are DVI --> DisplayPort or VGA --> DisplayPort.
You do not need to know exactly which adapter you need at the time of order, and WVLS sill seek to order adapters in bulk, so an additional "adapter charge" may be added to your overall order (usually approximately $10). If you know you have an older monitor, you can indicate the number of adapters you think you may need to complete your setup.
Price TBD during billing (approximately $10-$20)
