DVI-D Power Saving Mode (LG D2500N Monitor)

[jansenfinn]

I have bought a new monitor yesterday, as always I have the monitor unused for around twelve hours to make sure the temperature is good. I'm typing this on my old HP 1740 monitor which I connected to the onboard graphics. This morning I wanted to connect the LG D2500N to my computer but when I start it up it says DVI-D Power Saving Mode. The graphics card fan is spinning and it's connected to the PSU. I made sure that I turned of the PSU while connecting the monitor. How can I fix this?
Graphics card: AMD Radeon R9 290
PSU: Corsair CX600
Monitor with the DVI-D Power Saving Mode problem: LG D2500N
Old monitor connected to the onboard graphics: HP 1740

I'm not a native speaker so forgive me if my English is bad.

Try different graphics card and monitor ports.

I tried different ports and that didn't work either. Now I have my old GTX 750Ti and it does work now. I'm going to put the R9 290 back in and see if it works.

It works with my 750Ti but not with the R9 290...
Pictures don't work either so I will post them manually.

OK - RMA your 290 then.
