So I've just got a second monitor for the first time and I'm in the process of attempting to set them up. My graphics card (AMD 7800 series) only has a DVI and HDMI slot, so I've got my new monitor in the HDMI (as it has no DVI) and my old one is attached via DVI (it has no HDMI).

The problem is that while the new monitor connected via HDMI is showing up on both my GPU control panel, and on my windows control panel - it is completely blank. It's status light is on, and it isn't projecting any problems but it's totally black.

Am I missing a simple, yet crucial, step here?

Any help would be much appreciated.

Have you got the latest drivers installed for the monitor?

Would probably help if you posted some more information about the monitor e.g model number and what operating system you're using.

edit: Try booting up your computer with only the HDMI monitor connected.

So you've ticked "Extend my desktop to this monitor"?

That existed before all these fancy gfx card programs.. not sure if it still does?

Just to cover all bases, can you use the new monitor as the sole primary monitor? Just to make sure it works and wasn't DOA.

Monitor is a Samsung S24D590L, and using Windows 7 Ultimate 64-bit.

Booted up with only the HDMI attached - still nothing on the screen. Which is fucking baffling because it detects it.

Monitors have drivers now??

Make sure you have the latest gfx card drivers too?

And latest motherboard/chipset drivers to make sure HDMI is happy?

Yeah some monitors have their own software these days.

You should try wiggling around the hdmi cables, and making sure they're in the whole way. I've had similar issues with hdmi cables being loose.

My girlfriend just plugged her tablet in to my new monitor via HDMI, and then when I switched it back to PC it randomly detected and displayed it.

The new monitor is cropped despite being at 1920x1080, but I imagine that'll be a simpler hurdle.
