DVI-D - DVI Digital (True Digital) DVI-D is a direct digital connection between your video card and your monitor. This type of connection provides a fast transfer rate, high quality image and no quality loss due to the fact that all signals from PC's are purely digital; no digital-analog-digital conversion is needed.
Typical costs: 1  A half-size keyboard with training software averages $200-$250. Expect to pay $550-$2,000 or more for a full (88 keys) digital piano keyboard with touch-sensitive keys and a damper pedal. 2  Beat-up traditional pianos are often available for $250-$500.
For example, if you're on a budget, the Rosewill RK-9000 series are mechanical models with various switch types, so you can choose the switches you want in the keyboard before you buy it. Rosewill's models are usually well shy of $100 as well, so you're not breaking the bank on a mechanical keyboard.
