D-Sub No Input, Computer will now show information on LG Flatron monitor.

I was building my computer. 1st attempted, failed. 2nd attempt, Yay! It worked! Of course the monitor had to ruin my joy. So, when I POSTed the motherboard, everything worked fine, UEFI popped up. The when I assembled all the parts, the LG Flatron E2350 just said "D-SUB - POWER SAVING MODE". I suspect it's the graphics card, but how do I fix it? Here are my parts:

i7-4790S
Gigabyte R9 270X
ASRock Fatal1ty z97 Killer
Hyper 212 Evo
OCZ/Firepower ZT550W
8GB G Skill Ripjaws X
TP-Link Wifi Adapter


May you tell me what the problem is and how to fix it? I'm desperate! :O

Thanks in advance!

So you see nothing on the screen besides that message? Have you tried connecting the graphics card to the monitor with other cables (HDMI, DVI, etc.)?

I don't have anything else. I tried and without the card, I could install windows, but with the card it would just not boot.
I'm installing the drivers, will that help?

I connected DVI adapter to VGA and then reinstalled AMD's R9 270X drivers with AMD Catalyst. Then it reset the screen size and worked.
