New High-Tech HDTVs Appear

At CES 2007, many new technologies for televisions are creeping up. Companies including HP, Samsung, Panasonic, Sony, Sharp and LG Electronis have never offered a wider array of various models with different feature sets. If you're planning on buying an HDTV soon, make sure to do your homework. You will want to wait, however, until June 2007, for everything to be released.

Here are the four main features to watch out for:

  • High-Definition Multimedia Interface (HDMI) 1.3: Faster data throughput, higher color bit depth, higher-quality audio, among other things.
  • Two-way CableCards: program guide information, video on demand, and so on.
  • 120-Hz refresh rate LCDs: doubled refresh rate (standard is 60-Hz) equals less blur in motion scenes.
  • LED-backlit LCDs: Better color, faster response (often found on sets with the 120-Hz refresh rate).

Most LCD panels are cross-application (that is, useful for multiple applications), so doubled-frequency LCD panels would indeed see more usage (not just in the HDTV sector, but even, perhaps especially, in the PC/console display sector) especially in terms of gaming, where the 60 Hz refresh rate is a disadvantage for LCD panels vs. the still-extant CRT.

In a semi-related story, Westinghouse Digital Electronics (actually longtime Chinese display manufacturer/marketer CMO, which used to sell PC displays in the US under its own brand) *continues* their re-invasion of the United States CE marketplace with two additional WS LCD displays (19" and 22") under the Westinghouse Digital brand. In fact, led by WD/CMO, Gateway, LG, and even HP, such displays (even in the 22" screen size), are now less than $500USD (MSRP), and in most cases, are $400USD (retail). To put it succintly, at no time has screen real-estate been this cheap, not even for CRTs! I bought my current 17" CTX (OEM) display in 1998 for $249USD (new) and while 19" CRTs have undercut it, the viewable area was often little (if any) more than the CRT it would replace. On top of that, CRTs eat desk space like Skittles; with a FP display, even a 22" WS display, I'd gain not just *screen* real-estate, but *desk* real-estate (it's like buying a one-acre building lot, and getting a second actually usable acre thrown in at no extra cost). Lastly, there is the DVI/HDMI/HDCP issue. Almost *all* of the 22" WS LCD displays I've mentioned support HDMI/DVI *at minimum*; in fact, all except *one* support HDCP (which use as a display for HD DVD/BR requires); HDCP support in graphics adapters (even AGP-bus) is becoming a checkbox item (Item: *all* X1950 Pro-powered graphics cards, without exception, support HDCP). Therefore, the cost for adding HDCP compliancy is turning out to be either little or none.

How can upping the refresh rate make any difference if the source is still providing the signal at the same frequency?

On a monitor, the refresh rate only affects whether your eyes get tired or not, but they don't have that problem on a TV.

Heck, all computer LCDs are 60hz and nobody complains.

Exactly right, especially the first sentence. The only guess I could make is that they're going to make them accept computer resolutions in addition to 720/1080 i/p standards.

I complain.

Look around in quake 3 or any other fps game with 500hz usb rate and 60fps/hz then do the same in 120hz/fps. Much easier on the eyes to watch big transitions at high fps (like looking around), and you get more responsive feel of the game. Fast and competitive online games like Battlefield 2, UT2004 and especially Quake 3 really benefits from 100ish fps/hz.

A 120hz high-PPI OLED that also can run at 100 (battlefield2) and 85 (ut 2004) would be all right :)

Noticed there is no mention of pricing, not even ballpark figures. Guess they don't want to scare off a large pile of (potential) customers so early...
