I know there is a separate forum for Scalers/Video processors but I wanted to get some feedback from the people in this thread that have experimented with some of the newer projectors like the RS1, Marantz VP-15S1, and Sim2 HT3000e.
Basically, I wanted to know if you think the external scalers give a "noticeable" benefit over the new projectors' internal scalers. I am looking to upgrade from a Dwin TV3E which is the two box solution with a separate scaler/video switcher to one of these new projectors and I was wondering if I should invest in a new external scaler/switcher or just get a dedicated preamp/hdmi video switcher.
My primary sources are DirecTV(HD DVR) and a Toshiba XA2 HD DVD. This makes up 99% of my viewing material.
Thanks in advance.

im sure it looks nicer, 2-3,000 dollars nicer, no..but i guess if money is no object than its not a big investment. I wish i had a scaler but it would really only help me for my lower res stuff.

Thanks. That's kind of what I was thinking. I think external scalers made a lot more sense when we were primarily dealing with various 480i sources and projectors had minimal or no scaling. -but now that most of the stuff I watch in the theater is either native HD or upconverted to HD via the DVD scaler, combined with the fact that most good projectors have decent internal scalers, I really don't think I need it. On the other hand, it is evident in the "Video Processors" forum that there is definitely still a market for these products so...

I think that there is no question a video processor helps. But, I think that the improvements are becoming more subtle as the projectors are utilizing better and better internal processors. Thus, the value goes down.

I also think video processors give you more options on what you can do with picture than maybe the standard scalers built into the projector.

Very true. Most allow custom aspect ratios, change of refresh rates/timings, etc...

Plus there is no question a 2 box setup is an easier installation.

Having owned a couple of high-end scalers, I am of the opinion that their simple ability to scale and deinterlace often does NOT provide a visible image improvement over what you get from the processors in many of the newer projectors. For example, I thought that the HQV processing in the Vantage HD product noticeably improved the image I saw from a SIM2 HT3000, but offered little in the way of improvement to the Sharp 20K.

Where an external processor can really make a difference is when it includes controls that allow you to calibrate the image better than what the projector's native controls allow.

For example, the VXP-based Optoma HD3000 has both a full compliment of gray scale and color decoding controls that can make a real difference to image quality if you are willing to have the projector calibrated. Also, the endlessly always-around-the-corner Lumagen Radiance will have both of these features and they promise to add a complete CMS that would allow you to dial in nearly perfect color. Either could make a profound difference.

The Reon VX in my HC5000 does a superior job with component video compared to the ABT in my Yamaha receiver, better than my former DVDO and Lumagens.
