I am new to projectors but according to my research it looks like that a DLP model would provide me with better black levels? Dark scenes look like a faded gray even in a complete dark room.
I noticed the contrast ratio on the Optoma is 20,000:1 as opposed to 12,000:1 on the Epson.
Am I right by assuming I'll be getting black levels with the Optoma?
I currently own a Mitsubitshi DLP TV (1 chip) made in 2009 and it appears that I'm not susceptible to the rainbow effect. Is it also safe to assume I won't be seeing the rainbow effect on this projector?
If you need to fit a certain screen-size (if you already own a screen) and will need to do it from a certain mount/place, make sure you take that into consideration during your projector shopping. http://www.projectorcentral.com/projectors.cfm
is a good resource if you need to fit an existing setup. IF you are fine moving a mount or changing the screen..you should be fine.
Basically any DLP (including this 141) will give much darker blacks and less visible screendoor than your current projector, so that's easy. With this particular projector (the 141) you'll be losing some color accuracy, color-brightness, and the old/non-HDMI inputs. If that's an okay trade, you're in good shape.
If not, the w1070 will offer all the same benefits of improved blacks and no screendoor along with bright and accurate colors and all the classic inputs as well as HDMI..but it costs around $700 and will often need to be mounted slightly closer to the screen than this 141.
If color accuracy and brightness isn't a big deal, BUT you'd like to keep the older inputs..the Optoma hd131xe or hd25e will give you what you need for a similarly low price.
It does sound safe to assume you'll be alright with the 2x colorwheel of the Optoma.
If not, the w1070 is a faster colorwheel option as is the more expensive Optoma 151/hd36 and 161/hd50.
If you'd rather try to get better blacks via LCD, the Epson 8345 or (if you are shelf-mounting)the epson 3000, will give a solid contrast improvement that isn't terribly far behind the DLPs and may give a slight improvement to your screendoor situation..though not nearly as much improvement as the DLP would. They'll be more expensive as well however.
-Do you need VGA(older computer monitor) or RCA/composite (3 or 5color cords like your old VCR used)..or is just HDMI alright?
-What size screen/wall are you looking to fill and where do you want/need the projector mounted?
-Would it be alright if your new projector was a bit dimmer than your current one? Blacks would be MUCH darker but bright stuff could also be a little dimmer in certain settings.
Also, just so you know, those contrast specs listed by the manufacturer are very far from the truth. Contrast numbers (and to a smaller extent, brightness numbers) are not policed at all so manufacturers are perfectly allowed and willing to make up outrageous specs that are nearly meaningless.
Real-world measurements show the 730HD to have contrast in the 400:1 ballpark and the hd141 should fall in the 700:1-2100:1 range depending on which settings you prefer.
For reference; a professional cinema will have about 2000:1 Contrast or less, a cheap computer monitor can be as low as 500:1 or lower while a good LCD flatscreen TV will measure up in the 1500:1-2500:1 range. A decent plasma TV should hit 5000:1 while a fancy one will get 10,000:1 or more.
Basically you won't find a non-plasma/non-OLED TV that beats 3000:1
you won't find a non-JVC projector that beats 6000:1-7000:1
you won't find a projector under $2000 that beats 2000:1 (except a few deals on the AE8000).
That's how far off manufacturer contrast specs are.
1million:1 contrast?! nope..more like 2000:1
