While browsing the forums, we noticed there were an unusual number of LCD questions. It’s been a while since we posted any new LCD news, so we are going to go look at LCDs both on the novice and expert level. It is our intention to keep this article up to date with new changes, but it requires the feedback of our readers in the forums.

Among all of the hardware sectors, displays have risen to become the most explosive, controversial and emotional sector of all. In three years, we have seen LCD sales double and triple. Almost 85% of all new displays sold are now LCD. To say that LCDs will play an important part in the future of personal computing would be an understatement.

Unfortunately, since growth in the LCD market is volatile, confusion and rumor convolute almost every review and guide on the internet. In order to explain anything and everything, we will start with computer monitor basics, going all the way back to the history of the LCD and then finishing with the future of LCD and flat panel technology. Also, we will provide a glossary at the end of this article.

    I'd just like to bump #60. He asks some great questions - anyone have any answers?

    The 15" laptop 1600x1200 vs 19" desktop version has always bothered me. I wish I could buy my ThinkPad's display as a standalone device!

    Thank you Kristopher for your informative article.

    I have been staring at a computer or TV monitor for over 25 years and between the CRT and aging, my eyes have been getting worst every year. I am interested in getting the best video quality monitor for under $1000 per monitor. After reading your article, I would assume that a CRT would be the best choice. However, I am in the market to purchase TWO monitors. This is so I can view two programs simultaneously or when a client comes over, rotate the second monitor for their viewing. I mostly stare at numbers, words and Internet images. Also, I prefer larger monitors (i.e. 19"+). Should I consider two CRTs, CRT as my primary and LCD as the secondary, or match monitors and save real estate with two LCDs? What models would you recommend?

    Your suggestions are appreciated.

    Also, it seems that marketing is mostly centered on inches instead resolution. A bit too often this is also true for reviews which tend to place things like elegance of design, or number of USB ports or some such, above petty details like displayable desktop area.

    Is this just some braindead carryover from CRTs, or does the average consumer really not care about the number of pixels he gets?

    One thing I'd like to know is why is that usual native resultion for 19" LCDs 1280x1024? Or more specifically, why do 17" and 19" LCDs generally have the same native resolution.

    I would have thought that the logical progression would have been (based on the resultions usually used on equivalent sized CRTs):
    15" 1024x768
    17" 1280x1024
    19" 1600x1200

    But no, you generally have to go up to 21" LCD to get a 1600x1200 native resolution. And it can't be a technical problem, because we have 15" notebook LCDs with 1600x1200 (and higher) resolution.

    So, does anyone know why the LCD industry made the bonehead decision to standardize on having 17" and 19" LCDs have the same native resolution?

    PS. And don't bother pointing out that there are a few 1600x1200 19" LCDs. I'm aware of these exceptions. I just don't understand why this isn't the standard.

    That is anybody's guess. No way to find out unless you buy one and open it up. Then use the panel# to get the specs at the panel manufacturer. (And wave your warranty goodbye like I did mine :( )

    Are this 16.7m color specifications true or is the same 18 bits AUO panel?

    ACER AL732 - 17"
    Technical specifications
    Display size 17"
    Display type Active color matrix TFT
    Display area 338 x 270 mm
    Brightness 260 cd/m²
    Resolution 1280 x 1024 pixels
    Colour 16.7m (8-bits per color)
    Pixel pitch 0.264 (H) X 0.264 (W)
    Contrast ratio 450:1
    Response rates Total: 16ms

    Thx

    #55: on the contrary, lg.philips actually informed us of the opposite. While technically the dithering does not impact the response time, electrical modulation does. This is a direct result of how many bits the signal is capable of.

    Are there any formal reviews on new substrates that offer 10-bit gamma correction? In particular, I am considering either the Sharp T1820 or the EIZO L695 (L685EX), and considering that their specs are fairly similar, I assume they are using the same substrate. Supposedly the 10-bit gamma correction is capable of displaying a 1024-step greyscale, which can help prevent banding in subtle gradiants.

    Unfortunately, neither of these LCDs are widely available for me to perform my own eye-testing. Ideally if someone can offer advice on whether this is an overpriced two-step-conversion technology (as with using an analog cable on an LCD), or if this truly offers discernable benifits, that would be great!

    The Sharp T1820:

    Also worth noting, EIZO CG18

    ALL TN+film panels use dithering (or Frame Rate Control as they call it) to interpolate 24 bits colors with a 18 bits signal. These panels are either quoted as 262K colors (64³) or 16.2 millions colors (253³). This applies to ALL 15" monitors and almost ALL 17" monitors (including the Samsung model quoted as 16.7 millions in the article). However all 18" and higher monitors use panel driven with a 24 bits value.

    BTW, dithering has absolutely no impact on response time.

    Info on the Samsung X line fo monitors, in case anyone is interested.
