$300 seems pretty affordable and I welcome more competition to this small market.
Will this correct for the edge stretching seen on most every game when using 3 monitors? Is there anything else out there that will correct this? Anything for less than hundreds of dollars? That kind of money to fix a mild annoyance is way out of my reach.
In my opinion, this is the single most important issue when it comes to ultra-widescreen and curved projection gaming. It is up to 3d game engine designers to allow for multiple render points across your display. Most hardcore flight and racing sims support this, but it is extremely rare in mainstream software.
It is a small market so it is understandable, but also a chicken and egg problem. If it were available to consumers it would only serve to further push demand for high-end GPUs, I think.
