Only can get one monitor to work

truckinusa 850 214 November 5, 2015 at 08:37 PM
I have an older monitor that is 1600x900 resolution and my computer will not put a display on my 27" monitor trying to run them in dual screen mode. Do I have a dead video card? I can boot up the 27" alone and see the windows symbol, but after that it flickers and the screen goes no signal. This is a brand new monitor. I thought the capacitors were dying in my old monitor so I bought a new one. My vidoe card is a r9 270.

We need a lot more details.

What make and model is your computer?
What operating system are you using?
Have you updated your graphics drivers?
What connections are you trying to use to the monitors?
Are the monitors on the correct inputs?
Can you get each monitor to work one at a time?

PC is sabertooth 990fx with am fx-4100
Video card is a MSI R9 270 2GB
Monitors are Benq xl2730 and acer 210sl

I was running a dell monitor u2311h and alll of a sudden it quit displaying. I thought it burned up the capacitors in the PSU. Haven't had a chance to test it. I bet it works.

I plugged in the smaller Acer monitor and it will run on its own, but the Benq monitor will not run solo on any of the video card outputs. I need to know why.

So your having problem with the Dell and Benq monitors?

Is the power adapter in the Dell internal or external? If it's external it should be easy enough to test with a multimeter and then replace if its bad. Do you get any LED's on it? Bad capacitors can usually be spotted visually as well. Usually if it's a problem it's well known so a google search might help you.

As far as the benQ again I would check power at the source of the adapter if possible. if anything is under warranty start that process now. I am betting your BenQ is still.

I would then look at the source of your incoming power. It's not that common to blow capacitors this day especially on newer stuff. Make sure your voltages are up to spec and not spiking or browning out. Might want to consider a UPS.
