HDMI Monitor; Cable or Adaptor?

I am looking at getting an ASUS VW246H Black 24" LCD Monitor and I am interested to know whether my HIS Hightech H487QT1GP Radeon HD 4870 can support the HDMI that the monitor offers.

On the 4870's spec page, it notes that HDMI is possible with an adapter, but HDMI adapters seem to be just as expensive as the monitor. I also noticed that there are cables that can connect a male HDMI device to a male DVI device (for much cheaper).

My question is, can I use the monitor's HDMI function with the aforementioned cable, or must I get the expensive adapter (or is HDMI even worth it)? If the cable can't work, I can stick with DVI on that monitor.

surely the monitor has both hdmi and dvi?
the adaptor costs about $2, and you usually get one with a graphics card. I got 1 with each of my gpus, and dvi-vga with each too. If you want audio in the hdmi you need the connector that links the sound output to the graphics card. (or the front of the case, etc)

actually, they should cost about $2, but places seem to charge around $40. But that is for gold ones... copper works fine

I can see you're not using Newegg's potential!

That monitor has D-Sub, DVI, and HDMI. So, buy the HDMI cable.
