Sony‘s BRAVIA KLV-40ZX1M is a 40″ 1080p LCD monitor. The term ‘monitor’ might sound misplaced here but that’s what’s on Sony’s website and there’s a good reason for it. Within the display industry displays that do not have a built-in tuner (ATSC, NTSC, etc.) are considered monitors. Of course there are monitors that have built-in tuners and categorizing them is a bit of a challenge but still they would belong in the TV camp. Another indication that this ultra-thin display is just a monitor is in the prefix that Sony uses: KLV. Typical LCD TVs have the KDL prefix. Because there is no built-in tuner the KLV-40ZX1M is ultra-thin at just 1.1″ thick. Another reason is the backlight.
The KLV-40ZX1M uses LED backlights but they are edge-lit, allowing for the ultra-thin profile. But there are drawbacks to that: no local dimming. I am sure engineers are working hard at pairing edge-lit LED backlights with local dimming but you’ll need to wait for that. So the 20,000:1 contrast ratio that you get from the KLV-40ZX1M is global dimming. What’s global dimming? That’s when the entire backlight’s brightness level is manipulated based on the video content’s overall brightness. So if the scene is dark the entire backlight is dimmed down. On the other hand if the scene is bright the opposite happens: full brightness from the backlight. More important than the dynamic contrast figure on this display is the static one: 4000:1 is very good.
I like simple. And the KLV-40ZX1M has a very simple design. Connectivity is simple too: a single HDMI port. Simple will cost you though: $3999.99 and will be available on 2009.03.11, that’ll be tomorrow.
