Reviews

Recently, with the help of Cleveland Plasma, I've had the opportunity to write reviews of some of the very latest displays to post on the AVS Forum.

Chad B's totally subjective comparisons and rankings: (updated 5-1-2010)

"pop" and impact: 1 to 10 points

Main contributing factor: modified ANSI contrast

Lesser contributing factor: light output, ABL

The modified ANSI contrast ratio is a measurement of the difference between the darkest blacks and the brightest images when both are displayed at the same time.  High ANSI contrast is essential to providing a punchy image with a high "wow" factor.  A set with poor performance in this regard may look washed out and bland with regular program material, even if it does well with MLL.

Color: 1 to 10 points

Main contributing factor: color decoding, color gamut

Lesser contributing factor: grayscale tracking

I place most emphasis on accurate fleshtones with this test, though other things come in to play as well, such as neon greens or poor grayscale tracking.  A display has to have a combination of measurably accurate colors and subjectively natural colors to do well.

Viewing angle: 1 to 7 points

This shows how well the image holds up for viewers not seated directly in front of the screen.  To a varying degree, LCD sets tend to have less color and contrast to the sides or above and below. 

Versatility: 1 to 7 points

Main contributing factor: glare, light output, panel darkness

Lesser contributing factor: seperate day and night memories

This shows how well a display is able to handle any room in the house.  All displays look their best in a light controlled room, but what happens when the curtains are open during the day? 

Shadow detail: 1 to 5 points

Main contributing factor: gamma (darker end)

Lesser contributing factor: brightness stability

This tests how well you can see dark images.  For example, dark suits may turn into a black blob, with no detail visible. On the other hand, dark images may look too washed out without a sense of depth.   I feel that lack of visible shadow detail is a more serious issue than washed out shadow detail, though, so lack of shadow detail will get the lowest scores.

MLL: 1 to 4 points

This is the set's minimum luminance level; determined by how deep the blacks appear to be with a 0% signal in an entirely dark room.  A truly dark fade to black in a movie is an awesome experience, and contributes a sense of power and "wow" factor.   

Depth and dimensionality: 1 to 3 points

Main contributing factor: gamma

Lesser contributing factor: stability

Does the display have a good sence of natural depth in the image?

Stability: 1 to 3 points

Some sets may show visible pumping as their backlight, iris, or ABL (automatic brightness limiter) changes with the picture content.  It may also cause shadow detail to fluctuate from scene to scene.

Resolution and detail: 1 to 3 points

Most 1080P sets do very well with this test, so it's really just a test of if it is perfect or merely very good.  A "dot by dot" or pixel perfect aspect ratio helps here.

Smoothness / naturalness: 1 to 3 points

Some displays add a sence of graininess, dither, or texture to the picture, which can cause a "dirty screen" or "silkscreen" effect.

24P: 1 point

Can the display show 1080P/24 at a multiple of 24 without flicker or uncorrectable calibration issues?   If so, it gets a point.

Miscellaneous issues: up to -7

Problems such as convergence, flicker, motion artifacts, lines, geometry, etc.

Rated sets are ones that I have either owned, reviewed, or calibrated enough of in different situations to have a good handle on their performance.  In most cases, the ratings will be the same for a different size set in the same model group.  All ratings are for after a thorough calibration.

These are not end-all, absolute rankings; they are my subjective, possibly imperfect, but informed opinion!
