I've just bought 2 identical 23" monitors, Acer V233H to be precise.
On my graphics card (ATI Radeon HD4870), I have 3 outputs. 1 HDMI, 1 DVI (or maybe DVI-I?) and another one that I haven't seen before (it's not VGA though).
So 1 of the monitors is connected directly via DVI, where as the other one is connected via an DVI-to-HDMI converter and inside the HDMI port of my graphics card.
The color difference between them is quite significant, the HDMI one is a lot cleaner and brighter even though I've reset all settings (both on the ATI card and the monitor).
Could this really be due to the converter, or am I missing something obvious?

This is probably differences in the monitors. The signal being fed to both is digital, so the cables and converter are able to preserve the contents exactly as they transfer the signal to the monitors.
Your best bet is to adjust the monitors until they are as close as possible.
