If you decide to do the H5080..

It would be interesting if you could compare black levels between the Vivitek and the LG CF181D. Especially if the Vivitek is as bright as the Optoma HD8600 in best mode. Thanks!

Yesterday I stumbled across a really inexpensive projector or family of projectors. I hadn’t heard of them and that’s your fault. Like thousands of others, I expect to keep up on projector developments simply by reading your blog and website.

So what about OX Pro and Favi?

I think these are Chinese products but they are not just knock offs of Japanese, American or European technology. They all seem to use a unique super cheap lamp unlike any other I’ve ever seen. It only costs $28 on Amazon and supposedly lasts from 6,000 to 8,000 hours. From the pictures on their web site it looks a lot like the High Intensity bulb in my desk lamp. My desk lamp bulb costs maybe $10. My projector bulb costs about $300 (for a Japanese bulb) or $200 (for a much inferior Chinese bulb).

All the OX Pro machines are advertised as HD 1080 projectors although with careful reading its clear that these are not native 1080. Some are only 800 by 600.

OTH they have “extra” features. Most have built in speakers and some have built in DVD players. They start at just over $200. At that price you could buy one or more models and report to your faithful readers just what is going on here. These things don’t seem to be business projectors nor are they very much like Home Theater projectors.

OK, relax, I meant the HD8600, not the HD8200. Didn’t mean to get everyone all concerned…

Yes, it looks more like an 8600, it has the same weight, and offers different lenses, like the HD8600.

The confusing issue is the contrast – the HD8600 claims 50,000:1, vs 25,000:1. (the HD8200 is 20,000:1).
Vivitek uses pixelworks for the CFI. That’s true of Epson. I’m not sure about the Optoma (I’ll have to double check), but the point is, that even if they (H5080, HD8600) both are using Pixelworks, that doesn’t mean they are all of the same calibre. We shall have to see… -art

Also, the 8600 may in fact have the frame interpolation system. Vivitek lists a feature called vivimotion. Again, this would almost certainly mean it’s an 8600.

The 8600 uses a 220 watt UHP and the 8600 uses a 280 watt P-VIP, a more advanced UHP system. I have no idea what the 5080 uses for a bulb system, but the wattage matches the 8600. Total wattage is slightly lower on the 5080 than the 8600, but far closer than it is to the 8200. Again, I think this points to being an 8600.

I thought the Vivitek 5080/2 was an offshoot of the Optoma 8600 because of the specs, same size and casing they shared.
