Question/Problem
What about the dimensions and the power supply of the device Sensoray 2253?
Solution/Answer
The external USB video card Sensoray 2253 has got the following basic dimensions:
Length: 105 mm
Width: 85 mm
Height: 30 mm
Especially note the specifications regarding the power supply
Current: 300 mA
Voltage: 1.5 V
Power: 1.5 W
A current supply which is significantly lower than 300 mA will get the control lamp flashed up only weakly. So the device will not be able to properly transmit the video signal. Proceed as follows to resolve this issue:
Make sure the device is plugged directly into a USB-port located on the computer/notebook.
Make sure you have dowonloaded and installed all available chipset updates for your computer hardware: some chipset updates are able to improve the power supply via the USB-ports
