But I have not been able to find any info on the current state of edge blending (with a PC). I have two LG PA70G's, and I'm pretty sure they have no built in support for edge blending, so it will need to be done in software. I plan on using a Windows 7 computer, with a Radeon HD 6900 to do dual monitor output. The question is, what are my options as far as edge blending? Don't all modern video cards support that 'eyefinity' thing? So they must have some blending software for people who use multiple projectors instead of multiple lcd monitors? Since I was thinking about running both in 4:3 mode (for a 8x3 desktop, close enough to 16:9 for me), It seems like all I will need to do is line them up perfectly, and just overlap a SINGLE column of pixels, then tell the driver to render that single column at 50% brightness, right?
A quick google search for "edge blending software" led me to some graphic cards and pc software options. Try asking Snipe3000, in one of his videos it says he was using Warpalizer software. I think this is the website.
Matrox m-series video card has edge blending capability. However, the product description says it works with Panasonic & Mitsubishi edge blending product. From what I understand, the feathering of the edge is handled by the card, not the project. There should be no need to "edge blending projector"
