Optoma ThemeScene HD73 projector


DarkChip3 makes a showing in this competitively priced projector, but does John Archer like what he sees?

HD fans, meanwhile, will be chuffed to learn that the HD73 can handle 1080p signals delivered via either of its two digital inputs, one HDMI and one DVI. While we’re on the subject, other video inputs include component video, composite video, and...

Optoma HD73 review


Optoma's HD73 is easy on the eye, with a smooth white case and brushed silver sides.

Optoma HD73


I have been a keen supporter of the DLP form of projection from the inception of the format. The Optoma HD73 is a native 720p projector and is a very good example of the development of the single chip form. The HD73 is based on the Texas Instruments...

The screen size is 2600x1500mm. This quite a large screen and was filled by the Optoma HD73 without problems. This size of screen would display any shortcomings from this DLP projector

Optoma HD73


So, what we have here, is a new Optoma projector that will appeal more to those looking for a great image. I'm talking about, in the under $2000 price catagory

Excellent overall image quality for its price ; Very good black levels and shadow detail ; Very good color "out of the box" requiring only minor adjustment to be excellent color overall ; All-in-all, an excellent projector for movie purists with...

Definitely not bright - a projector for movie purists ; In brightest mode, perhaps the least bright projector around, not very suitable for use in rooms with modest ambient light ; Limited to about 100" or 106" maximum size screen with normal screens...

The bottom line, once I realized the screen size limitations I found the Optoma HD73 a pleasure to watch. It definitely had those "film-like" qualities that makes you forget you are watching a projector, and instead lets you to enjoy the movie. I think...

Optoma HD73 Home Theater Video Projector Review


Last year's Optoma HD72 was a big hit among home theater enthusiasts, and it was one of our favorite models of 2006. Now Optoma has released the HD73, an updated edition of the HD72 that places a bit less emphasis on light output and more on pure...

The Optoma HD72 was an outstanding projector when it was released one year ago, and it remains a solid, competitive projector today. The HD73 isn't an upgrade or replacement for the HD72, per se, but a similar projector made for different needs and...

Optoma HD73 Projector Review


The major improvements from the previous model are its 0.65" DarkChip3™ DLP® Chipset and DCDi™ interlacing and scaling by Faroudja®. DarkChip3™ allows 20 to 25% improvement in contrast ratio and by analyzing other factors in determining image quality...

Optoma HD73™ has DarkChip3™. High brightness, High contrast and advanced technologies like BrilliantColor™ technology and TrueVivid™ image processing makes it very attractive. Its street price is around $2000.00 is another main attraction. Considering...

Well worth the money we paid


Not perfect, but neither am I, so I settle for what I can get for the money. This is good for the money and I know you could get it cheaper, as I have seen it - so that makes it even better value. Going from a 42 inch plasma to this HD73 was a bit...

Lots of features for tweaking the picture quality, although the HD73 worked well straight out of the box. Good contrast and sharp images through HD and Blu-ray discs. Smooth white finish very stylish design which only weighs around 5 kilos and is near...

Like all projectors, they're scared of the light and weak signal input. It took me a while before I found a decent DVD source that upscales to 1080p and even so the HD73 works better with true HD or Blu-ray discs.

Do not let ambient light scare you away from this projector. I use it in a room with 3 large windows. I use those roller shades to block out most of the sun and the projector still looks awesome. I'm displaying it on a floated wall with Behr...

It's a projector! It is simply astonishing to see how people react to the size of your screen. I am at 94 in. due to room limitations, but i have no doubt this thing can go back another 10-15 ft. and still look amazing. I use it as my computer...

Like all electrical components, it's main enemy is dust, and the bulb is very sensitive to it. My lamp started flickering, i thought it was about to go, but it turns out there was a minimal amount of dust in the projector. The ceiling mount made for...

Wow -- Great for Price


I was thinking of buying a larger LCD TV. I'm rethinking this approach big time. I'm now a convert to projectors. It's like watching a movie. The screen in my basement 90-inch is so big that my 46 inch LCD looks puny.

I play this in my basement. I use it for movies and shine it on a cheap DayLite Screen to a size of 90 inch diagonally ; I run an inexpensive Blu Ray player from Panasonic (BD-35) and the picture quality is amazing ; The colors are incredible. It's...

It is not a fountain of light. I knew this before I purchased it. It needs a room without much ambient light ; Keeping the screen to under 100 inches on the diagonal offers a pretty bright and satisfying picture. If you want a bigger picture a brighter...

Great Projector


Overall, the projector is great especially if you are using component cables or HDMI. I have read some reviews about the brightness. I would say the brightness is not really an issue, it is visible in low light situations. If you are looking for a...

Looks great, especially when a high def signal (YPbPr or HDMI).

Not too many i can think of, especially for the price.
