法國有個網站寫了一篇HC 4000的評測文章。
雖然是2010年12月時寫的，但有些內容寫的不錯，提供給大家參考：
Test Mitsubishi HC4000(audiovideohd.fr)
原文因為是法文(小弟也看不懂)，可以用google翻譯來觀看內容。
下面貼一些英文翻譯的內容：

Mitsubishi HC4000
Posted by Walter Gregory 01/12/2010
Introduction
War rages in the market for DLP Full HD less than 1000 euros.
The major manufacturers competing offers more enticing than the other.
In all these models, whether Vivitek, BenQ, Samsung, Infocus, Optoma, Mitsubishi DLP chip found in 0.65-inch dark chip 2.
These chips are inexpensive DLP very successful, but they also mean contrast is: capping off at around 2000:1 after calibration.
The brand with the three diamonds is distinguished by offering us this new HC4000, the first Full HD DLP entry-level equipped with a smart dark chip 3, it was announced by the manufacturer with a contrast it: off of 3600: 1 and a brightness of 1300 ANSI lumens.

DVD藍波4的觀看心得：
Do not expect miracles from the processing inside the projector, we gave the game to scale the last adventures of John Rambo in our new player, the Panasonic BD-P100 to restore accuracy to the image .
Added to the treatment of Blu-ray, the contrast of the HC4000 is wonderful, a very good factory color settings makes justice to finally master this bad with entry-level projector.
The HC4000 delivers a beautiful image with a depth of field quite exceptional in this price range.
As you can see, this projector will need to give his best even with low resolution sources, the addition of a Blu-ray quality.
BD的觀看心得：
Mongoose fight scene (Blu-ray Casino Royale)
The image detail is less than that of a Vivitek H5085fd or Optoma HD87, but unlike HC3200/HC3800 models, we have not detected obvious chromatic aberration (this is a distortion of the image in the corners, resulting diffraction pattern visible on the same result as a lack of convergence on an LCD projector).
Again, the color rendering of this scene that we know well is close to perfect with very cinematic rendering of the whole.
The image is also based on this projector, the color wheel RGBRGB four-speed should not be a stranger to this feeling.
Scene of the arrival by air of James Bond at the Marina (Blu-ray Casino Royale)
So here we are in the field of excellence, the HC4000 projector is simply displaying the image the more fluid that we have ever tested with a projector in 1080p24 mode without the backing of a mode 120hz.
It's a treat to chain tracking shots, even the most hectic with this unit.
Mitsubishi should give lessons on this issue to other manufacturers about the solutions to achieve this result to the image.
The brightness is sufficient if it is average on this particular passage.
============
Colorimetry and Gamma
The factory settings are very good and allow you to consider using the projector without using a calibration.
We put you below, our measurements of gamma mode with film color temperature "average".
The projector has an option to adjust the gray scale to set the color temperature to the reference of D65 (6500K) and also a CMS.
If the calibration of the gamma and grayscale took us 5 minutes, it was impossible to properly adjust the brightness of the projector using the integrated CMS.
Too bad, because with the factory settings, our corrections have been limited.
Here are some statements of our measurements.
You will find that the film is set gamma to 2.2 linearly.
