Usb powered aoc monitor is blinking


Hello,

Active USB cables boost the USB signal not the 5v power lines. After about 6 feet the 5v power lines will only provide 4-4.5 volts and this is not enough to power the monitor. For this to work you will you will need to also use a powered USB hub at the remote end by the monitor. The USB hub will supply the power and the monitor needs and the active USB cable will provide the signal.

HOW TO USE USB HUB ON LCD BECAUSE I INSTAL USB IN LCD HUB BUT NOT WORKING WHAT IS THE SOLUTION METHOD? PLS REPLY WITH SOLUTION OF THE PROBLEM.THANKS!


Unless the USB hub circuits on the monitor is dead, the way to use it is to get a USB CABLE , the one side of the cable goes to the USB input port (A) of the monitor, the other will go to the USB port of the PC. If the hub in the montior is bad, you will be better off getting a stand alone powered USB hub.

I have a new macbook pro and want to use a diamond bvumd3 to have 3 independent displays. my external monitors are both Dell 2310 with 1920 x 1080 capability. I have the bvumd3 connected into my macbook...


You would have to purchase separate BVUMD3 devices in order to get multiple extended monitors. Since each BVUMD3 has one DVI port with a USB hub, the DVI port is the only port available that allows video. Using a VGA splitter will not work with our device since each DVI port is allowed to carry only one video signal through to the monitor. You could purchase separate BVU195 devices if you do not need to use the USB hub on the BVUMD3.

Usb ports on side of monitor does not work


First check that the USB cable is fully connected between the monitor and the computer. Next, check if the monitor's hub will work connected to another port on the computer. (Ports do fail and cables do loosen.) Next check that the device(s) in question will work when directly connected to the computer.

If the hub in the monitor has failed, check if your warranty covers the hub and is still valid. Otherwise, it will be cheaper to get a new USB hub.

I hope this helps.

Why don't my USB ports on my monitor work


1) good USB cable from Monitor USB input port to PC USB port?

2) Check pin 1 of the USB port, you should have 5vdc.

3) Your monitor's USB ports are basically the powered USB hub, but it must be connected to the PC USB port.

The cable from the Monitor USB input to PC USB output is good? Check to see if you do have 5vdc on pin 1 of the USB connector. Your monitor is basically a powered USB hub when it is connected to PC through a USB cable.

Why don't the usb ports work on the side of monitor


is there an extra cable, aside from the Power Cord, and the VGA Cable? if not, look on the back of the monitor, there should be a similar plug in like a USB printer would have, its kinda square. If there is, you just need a USB printer cable to make it work.

The USB ports on the left side of the monitor do not work. Why?


Have you connected a USB master wire cooming from the monitor to the PC? Check your installation manual. These extra ports sure are conveinent, but they are simply a hub and a hub needs a source.
