I have owned a refurbished InFocus X10 I bought off eBay for $400 shipped for 10 months now. I have put 2000 hours on it and it has gone from an apartment living room to a dedicated cave in a house.
I always knew that its supposed weakness was black level - being that it has a DarkChip1 and its more expensive siblings have a DarkChip3. The colors are always perfect, however, with very little fiddling required. It is also extremely sharp thanks to its huge glass lens.
Based on reviews and testimonials, I assumed the Epson 1080ub would blow it out of the water on black levels - and I thought the colors would be worse, but easily fixable in the end. From screenshots on review sites, I also thought sharpness wouldn't be any different.
To my disappointment, attaining a 1080ub just recently to try and upgrade was a complete waste of time.
The colors weren't just a little different, they were atrocious compared to the InFocus. Everybody had different recommended settings because every one is different, and no settings made it look natural. It was dim, very dim, compared to the InFocus in Theater modes - and getting acceptable lumens out of it made the black levels no darker than the InFocus. The contrast ratio spec'd of 50,000:1 (vs 7,500:1 tops for InFocus) is complete bullsh--. The native contrast of 4,000:1 is much more realistic. It never once looked like it had more pop or inkier blacks unless it was dimmed down to CRT projector levels, or was crushing blacks and killing shadow details.
Not to mention on a solid color, there was a red hue present across the top half of the screen, and it got worse in the right corner. It also had dust blobs, and wasn't even close to the same sharpness.
How did this projector get such rave reviews? It "turned the world upside down" as far as black levels go on a projector of its cost, but the similarly aged, cheaper InFocus was merely "entry level" black levels that would disappoint anyone looking for inky blacks. I expect no replies since these projectors are both 5 years old, but the difference was unbelievable for all the reviews I read.
BTW here is a picture of the InFocus at home.
