I am used to spending in the $300-$350 (refurbished or not) range for lower-end not-completely-home-theater-grade projectors (such as my past two Infocus projectors, the X1 and the IN24+), but my firm decision to stop doing the “projector shuffle” (buying projectors in that price range and realizing that once the bulb goes, it’s only $50-60 more for a whole new projector!) and get on the LED bandwagon led me to the FAVI Entertainment RioHD-LED-4 XGA (1024 x 768) Portable Projector – which is just not QUITE good enough for home theater. For one, it has a “0% Offset” – meaning that tthe projector must be DEAD center of the screen to get it to not use keystone correction…and the keystone correction takes the nice XGA resolution down to something that looks like SVGA (800×600) or worse. In other words, avoiding using fuzzy keystone correction is the exception, not the rule.

So…with a heavy heart, I decided to stop being quite so cheap and sprung the extra two hundred eighty bucks for this unit. It is somewhat bigger and significantly heavier (thought still lighter than my old Infocus X1 or IN24+ projectors), and let me tell you – with good source material, it’s stunning!

Obviously nowhere else are you going to get this large a screen in this high a quality for this price. I am even thinking (based on recent trips to Target, Walmart, etc.) that you can’t even get a smallish television at 720p that looks this good (WITH excellent source material, mind you…garbage in garbage out as ever, and that rule applies here).

Material that is heavily encoded/compressed to begin with is going to look flatter and less alive.

But proper 1080i/p or 720p material that has been encoded with care and high quality can look just stunning (for a cheaper projector).

As others have noted, the reds are quite eye popping.

I watched a bunch of 720p and 1989p torrent BR rips with mixed results. Some look good but not amazing, and a few (like the well-encoded copy of World War II In HD that I got, bluray rip) are at times eye-popping. Again – garbage in, garbage out, so make sure you feed this thing the best, because I have been stunned by this thing thus far on SOME material. It is capable of greatness, you just have to feed it great media.

Anyhow, still disappointed in the fan noise, people say in eco mode it’s “barely noticeable” (yes, maybe with the volume cranking), but I really wanted to be able to use it while listening to hi-res 24 bit / 96khz music files and let the silent sections be silent…unfortunately, not ideal, but oh well. Maybe a fan mod will come.

In any event, I am very happy with this unit and would STRONGLY urge anyone looking at the current lineup of Favi RioHD projectors to aim just a little higher. For example, we put in The Dark Crystal, and the opening scene on this projector was far richer, more vivid and detailed than on the Favi RioHD-LED-4 – unfortunately. Putting that projector in “KTV” mode (whatever that means) made it brighter, but it still lacked depth and magic…this one lacks depth and magic of a $1900+ Home Theater projector, but to a lesser extent. I think this is the current sweet spot (or some of this projector’s clones), so really consider just spending the extra two bills and enjoying your picture, instead of agonizing over it (or it’s placement).

In this comparison, it’s a case of the old adage “when you buy quality, you only cry once.”
