I have a NEC 3090 screen at home, its a gorgeous 30 inch 2560x1600 monitor and I have two Dual Link DVI input on this screen... I was considering perhaps buying a console and/or a blueray player to attach to the monitor, then I ran into the first limitation...
HDMI - Supports up to 1920x1080 The latter HDMI versions do support up to 2560x1600 but most devices does not seem to support up to this resolution, only up to 1920x1080 hence I would need some sort of up-converter.
I did a bunch of search and found a bunch of SD or 720p converter to 1920x1080 but didn't find any converter to 2560x1600...
I did find some DVI upscalers but the majority of them maxed out at 1920x1200 or so. My NEC 3090 has no internal scaler so it HAS to be 2560x1600 to accept the input.
The main reason why I am looking for an upscaler is so that I don't have to buy a tv that I probably will only use to watch some blueray or play a couple of console games. Plus I don't have the room for a large HDTV in my apartment anyway.
