No audio from my Acer monitor

There should be buttons somewhere on your monitor...one named 'Menu' there you should click on an option to change the positioning or horizontal/vertical then follow the instructions...usually the arrow keys...to move the frame to where you need it...hope I helped!

To connect anything to the speakers on your acer monitor you need to use an audio patch cable that has 1/8 inch or mini headphone jacks on each end. Like this one.
5mm Male to Male Stereo Audio Cable...

You connect one end to the headphone jack on your Surface RT and the other to the audio in jack on the monitor. Make sure the power is on for the monitor and that the volume on both is a third or half way up and you should be able to hear the sound.
This is for the monitors user manual.

The backlight controller has failed. It can be repaired or replaced.

Your previous monitor had built-in speakers. The Aces LCD monitor do not have built-in speakers, therefore you need to purchase external speakers and plug these into your computer.

connect stereo audio cable from monitor to pc audio output

Is the monitor supplied with inbuilt speakers..? Most monitors no longer have inbuilt speakers and this is why there is no place to connect the audio cable. You will have to purchase a set of external speakers and connect these to the audio output of your system.

Yes, you do. You need an stereo audio cable. It will have a connector like found on portable headphones on each end.There should be a recepticle for it on your monitor, usually marked light green. This cable would then connect to your computer's audio output. Although, I don't think your monitor has speakers.

I have not answered the question about this problem, however someone else told me that I would have to change my graphics card to take full advantage of the features of the X223W monitor. But they did not know what I had to change it to.

can you post an image that shows what you are referring to?

TRY NOT USING THE GRAPHICS CARD AND SEE IF IT WORKS THEN. IF SO I WOULD INSTALL THE DRIVERS AND THEN INSTALL THE GRAPHICS CARD.
