Buying an LCD

For all the wisdom that we can give you about how to spec out a monitor correctly, all of that is worthless if the monitor doesn't fit your personality. Unlike a video card or CPU, buying a monitor is a very personal experience. People have differences on how they angle the monitor, the level of ambient lighting, and some just have different design tastes than others. If one monitor specs out better than another, but looks hideous on your desk, it probably isn't worth buying.

Aesthetics aside, there are some key pointers to follow when buying an LCD. This may just be personal preference, but we always recommend buying an LCD from a retail shop. Since LCDs are such personal items - most likely the most personal computer-related item that you can buy - looking at it, touching it and just seeing it in person is something that can't be replaced by an online experience.

Keep in mind, when you go to a Best Buy or Fry's, the LCD monitors on display are out of calibration, physically dirty and probably receive a terrible signal from some sort of modulator that has been on for 5 years. There are very few exceptions where a floor model display will look better in the store than in an office or home.

Issues like warranty and pixel defect rate used to plague LCD buyers in the past, but quality control on most well recognized branded monitors today are high enough that we rarely experience these problems anymore. The most recent issues of defective pixels are usually limited to a few models like the recent debacle with Apple's cinematic displays. Almost every retail store has policies on LCD monitors that allow you to open the monitor packaging and view the monitor in the store before you take it home, and most retailers will replace LCDs that have dead or stuck subpixels, if you haven't take it out of the store yet.

    I do not understand why the Samsung 910V was tested and not the 910T which costs $10-$30 more but has DVI.

    speedi,
    I think people make a big deal out of "ooh, you lose information." How many people are actually cramming all 1,920,000 pixels with useful information? I'm not. If you are, ignore the rest of this post. Seriously, I don't see the big deal...on a 17" CRT, I think 1600 x 1200 makes fonts too small unless you bump up the font size/dpi etc...I ran my trinitron at 1024x768 and I still used large fonts. The thing that clinched the wide-screen purchase for me was that I've been thinking about buying an LCD for a while now, and, while playing CS:S I realized "Hey, I don't look at the top or bottom inch of screen because they're out of my field of view, however I look all the way across the screen." I think people's eyes are simply set up to process further across than they are up and down. Whether that difference is 16:9, 16x10, whatever, I don't think is relevant. Additionally, the 2005 has slightly better specs wrt response time, contrast, and I think brightness, for the exact same price as the 2001. I think the additional width is slightly more useful for me than the decreased pixel count, especially as it allows me to put two web pages up next to each other at a readable size, without any overlap or scrolling. I guess the 2001 would let you do about the same, but I like that extra inch. I would guess anyone who would be happy with the 2001 will be happy with the 2005, and vice versa. I don't think either is a bad monitor, especially at the prices they are available at after rebates etc. Hope my overly verbose reply is helpful to some of you thinking about one or the other.

    I want to clarify something. 24 million colours does not mean much. I read the article said it is enough to show 98% of the colours we can se. But we can not make that conclusion so easilly. We need other critical information such as dynamic range. It does not make a good monitor if it can display 24 million colours but not enough green, or deep enough blues for good sky/water and so on. Compare the monitors colour profile/characteristics against the CIE LAB model, which is a device independant model that encompasses all of the visual spectrum.

    As #61 said. The aspect ratio is wrong. The 5:4 LCD's require a 5:4 signal, like 1280x1024. The pixel ratio remains 1:1.

    It is rather for most CRTs that the aspect ratio is wrong if you run 1280x1024. I can't for in my life see why the recommended resolution for almost all 19" CRTs is 1280x1024, when it should be 1280x960.

    Also, the bit depth guide has flaws. It does not take into account that a LCD is almost linear in its gamma curve, while a CRT not. A CRT has a gamma response of 2.5. This means that it has higher resolution for low/dark levels than for bright. It can be as high as 14bits in dark areas, but less than 7 in bright. The Gamma function "shifts" bits from bright to dark areas.

    But because the LCD is more a linear device, it will have the same resolution over all levels. It will have to convert the gamma encoded video signal to a linear one. This will make you loose A LOT of resolution.

    A LCD will have to have at least 14 bits to be able to show all of the colours of a 8 bit gamma 2.5 encoded signal. More modern video cards even have 10 bits of resolution for the video signal.

    Also, something missing is colour gammut. It is how much or many colours from the real world it can display. sRGB has a very narrow gammut, whereas AdobeRGB is much larger (can show more of the colours we can see). If you want to perform any serious graphics work (photography, for example) you need a display that can do at least AdobeRGB or better.

    Compare the various colour profiles at http://www.iccview.de . You can even upload the profile for your own device (camera, printer, monitor, scanner, etc) to see how large it is.

    Another nitpick. I believe the VMW9 HD clip you played was 1080p not 1080i. Microsoft does not have any WMV9 HD clips that are interlaced ;).

    "19" and higher LCDs are the current sweet spot for LCD substrates. Recall that 19" LCDs have roughly the same viewing area as 21" CRT monitors"

    which is completely worthless because 21" CRTs easily do 1600x1200, while no 19" lcd does any better than 1280x1024. you get ~50% more desktop area from 1600x1200 than 1280x1024.

    really, when 15" 1600x1200 and 17" 1900x1200 notebook screens are flying out the door, the lack of desktop lcds that do 1600x1200 and higher is disturbing. if there isn't any demand for it, what explains the notebook lcd sales? the claim just doesn't make any sense.

    well actually it isnt exactly 15"x12", but you get the idea.
  • GOSHARKS - Wednesday, December 1, 2004 - link

    "That is, a 19" LCD should have an aspect ratio of 1600x1200, 1280x960, or some derivative thereof. Most 19" and 17" LCDs have an aspect ratio of 5:4 (1280x1024). This is OK, but you're looking at a 5:4 signal crammed in a 4:3 box."

    uh no. 17, 18, and 19" lcds with 1280x1024 resolution are physically 5:4. my samsung 192n's display area measues 15" wide, 12" tall - making a perfect 5:4 ratio.

    i am very suprised to see such an oversight coming from anandtech. in fact, the entire aspect ratio part of the article is pretty useless once this point is corrected.

    drinkmorejava: Ghosting has to do with visual interference on the signal. Motion blur is what you refer to, and that was not rated quanitively.

    I work on computers all day long... there is no logical reason why you would want a CRT instead of a nice LCD unless you can't afford it. Monitors like the 2001FP put CRTs to shame.
  • speedi - Tuesday, November 30, 2004 - link

    benk, how is the 2005FPW? I notice that you lose a lot of pixels in the aspect ratio, but other than that... do you have an opinion? I just ordered a Dell 2001FPS for $599 and want to make sure I didn't overlook the FPW when I "should" have gotten it instead. I love 1600x1200... but I am used to 1600x1200 on a Viewsonic P810, which is razor sharp. Does anyone happen to know how this will compare? I took the 2001FPS based on the former AnandTech review.
