Brightness issue What I have: Two pc's,(XPro&Ubuntu), two Acer Al1916 19" monitors, What I did: turned pc's on - then turned on monitors from wall power switch, one monitor is now >50% dimmer then the other. Have reset it multiple times and also swapped the monitors from one pc to the other. It's definitely the monitor that's dim and not a pc setting.  Is there some way to reset the monitor to default settings other then the menu option reset?

This is unlikely to be a monitor issue, more likely a browser issue.
Please ensure you have the latest version of Ubuntu, Firefox and/or Google Chrome.

that buzzing noise is frequency response from the cathodes (back lights) and the inverter inside that monitor.

Personally, i'd keep the brightness up a bit more to alleviate the issue. I'd also check to see if the power that is going to the device is clean. Sometimes there can be issue with power causing frequency disturbance and can cause some pretty random issues with power sensitive devices.

Try running a battery backup or power strip to see if it helps.

hi. turn on the tv and then use the remote. click on the menu and scan thru til you find picture brightness or picture quality. J.

it is quite difficult to install anything without mouse and keyboard.
try to use PS2 mouse or keyboard, it would have to work just fine, after that connect your USB devices, and it just might load the drivers need by it self

pls rate me FIXYA for help

franh, Typical of a lcd/fpd monitor! There is nothing you or hundreds of others can do to repair it all by yourself. I have repaired 3 monitors and helped tutor 2 others on fixya with their monitors. All had same exact symptom as your monitor. I need you to do a simple test for me. With failed Acer monitor near to your Fully Booted PC with a known good desktop being displayed on back-up monitor, quickly swap out the monitor cables from the back of the PC. Keep touching the CTRL key on you keyboarb every 30-50 seconds to keep the PC from sending out sleep mode command to monitor while doing the reconnect of acer to your PC monitor output port. Make sure the Acer also is connected to a live wall outlet/power strip. Turn on the Acer and note what happens. If screen shows a sharp clear image for a second, then goes black, do the following. Get a bright flashlight and shine it on the screen from a distance of 1 or 2 inches and tell me if you can see the desktop display. get back to me with your observations. I'm louie12fix on fixya or lmistyrel@ aol.com.

Did you also replace the power inverter when replacing the screen???

No there isn't any. there is probably a part that is damaged due to the surge u should get a new one or send it back to the company

See if your video card inside your PC hasn't come loose. Take it out and push it back in again to reseat the card. Then, once it's firmly secured, try the monitor.
