The reason I was asking is because I've been playing around with my HTPC. I have an Epson 8350 projector (and LOVE IT!!!). I discovered my Intel HD Graphics G45 isn't the greatest. I've read all about the Intel driver problems and have been trying to decide if it is worth upgrading to an ATI card. But I would have to get a new motherboard, cpu, ram & ATI card to do it. I don't think it is worth it since everything runs perfectly fine already.
But, here is what I've discovered. (I borrowed a PC from work with a newer Intel Graphics 2000 card, as well as an ATI 6450).
The Intel Graphics can't display the BTB or WTW with either version. The newer Intel can calibrate better though with the Epson.
The ATI Graphics can display the BTB and WTW. It looks best when it is set to output limited and the Epson is set to Expanded.
Currently, with my Intel G45, I have the Epson on Normal and I've calibrated to that with the Disney Wow and AVSHD disc. I don't have a calibration unit, so I've had to use the blue filter. So, I can't display BTB or WTW, but now that I've calibrated, I LOVE my picture. It is way better than before and I loved it before. Watching Prometheus on Blu-Ray was breathtaking. Wow.
But I can't help but wonder just how much better it would be with the ATI card.
