X-bit Labs has written a review of the Samsung SyncMaster 2263DX, this is a 22" LCD display with a 7" tandem display.
Coming together with the SyncMaster 2263DX, the UbiSync 7 is actually a standalone solution. It can be used in pair with any other monitor or even without a second monitor at all. Hopefully, the UbiSync 7 will soon be selling apart from the 2263DX. I’m sure there’ll be interest to this solution on the user’s part if there is appropriate informational and advertising support.
Check it out over here. The reviewer concludes the implementation of the 7" display is a success and can be very handy to display specific information.
