InFocus Darkchip4 IN83 Projector – Can InFocus raise the bar?

6-24-08:  Our next home theater projector review is the 1080p resolution, InFocus IN83.

I just received tracking information from InFocus for my IN83 review projector.  The IN83 is perhaps the first big name Darkchip4 DLP projector to ship.

UPS advises that it will arrive tomorrow.  Thursday night it will get fired up, in the theater, and I’ll check out it’s out of the box performance.   With luck, it will be calibrated by Friday night, and I can spend the weekend doing extensive viewing.  Look for the review to post around 7/8, sooner if I can (don’t forget – there’s the 4th of July, between now and then.


Not much else to say, other than the IN83 should be almost identical to the IN82 we reviewed earlier this year, with some minor improvements, and one major one – the switch from the Darkchip3 DLP chip, to the newer, higher contrast Darkchip4.  This allows even better black level performance.  

I’m extremely interested (as I imagine you are) to see of the IN83 can match the top performing projectors in terms of black level performance (the JVC RS1x, and RS2, the Sony VW40 and VW60, and the Epson UB series. 

Until the last year and a half, the coveted black level performance champs had all been DLP, but more recently LCoS projectors (JVC and Sony), as well as the Epson Pro and Home Cinema 1080 UB, have surpassed the best black levels of any of the DLP’s I have tested.  

This should be really interesting.  And, I’ve got a JVC, and an Epson here, for direct comparison!

The IN83 is one of the more expensive under $10,000 home theater projectors, but then so are most of the competition mentioned above.  InFocus sells the IN83 in the US, only through authorized local installing dealers.

Stay tuned.  -art

    I am insalliing a major home theater in a antigue firestation I have just recieved an in83 but have not installed yet since we are installing 14ft tall custom tower speakers and 133″ diag motorized screen before setting up the 1n83, it will be positioned with a 19ft throw. I took it out of the box it seems superior in long throw in semi ambient light against a painted wall and rendered the golden cilor of c3po from star wars. I would like to here your comments if this the machine for the application or is one of the other you have tested is better. I feel the infocus is great for contrast and has the lumen power for daytime use. I paid $4599 for it. Should I send it back, do you have a lower price outlet or a better performing unit in this price range? Paul Grynick


    Paul, if it works in your facility there, it should be an excellent choice. The only brighter projector, without doubling or more, what you spent, is the Optoma HD81-LV, and while I’m not even half way through my review of the IN83, my take, right now, is that unless I needed every possible lumen, the InFocus is the better projector from a picture quality standpoint. The Optoma has an outboard processor and far more inputs, but the IN83 is well equipped.

    I’d say go for it (or rather – keep it!)

    Let me know how your installation works out. BTW, wait a few weeks after it’s all up and running, so that your comments are after you get over the shock of how good it is. (just about every projector initially blows people away, if it’s their first one). -art

    I am Paul’s son, who did the initial research and recommended his purchase of the IN83. Three years later, and the projector has been very well received at the firehouse, featuring excellent lumen output for a very acceptable image in the presence of ambient light. Great picture quality on the 133″ screen. No regrets!
