WOW your customers with their own monitor. POS-X combines their EVO TM4C 15" Touch Screen with their EVO-RD4-LCD 15" Flat Screen Customer Display monitor for a jazzy, completely integrated system. Our combination includes the required power supply for the LCD monitor, rarely included by other vendors. If you're interested in the 8" customer monitor give us a call for price. We generally don't recommend the 8" size because it can be a bit difficult for older customers to see such small script. A video card may be required to run PostalMate Twin View depending on your computer model. Call us at 800-205-0650 and we will be happy to help with the details.
