what is the disadvantages of LCD monitor?

Q.

A. While LCD monitors have a lot of strengths, they still have weaknesses that might turn off potential buyers. However, it's our opinion that these disadvantages don't really detract from the benefits of using an LCD monitor.

* More expensive than CRTs. You pay for what you get; LCDs look good and are good for your eyes (see Advantages article).
* Dead pixels. When the electrical current to one or more pixels does not operate properly, one or more cells are permanently aligned, resulting in a dead pixel.
* Screen care and fragility. LCD monitors may be slim and sexy, but they're also more prone to damage and screen breakage.
* Native resolution. LCD monitors can only display information well at the resolution they were designed for. At any other resolution, image quality will suffer.
* Pixel response time. In videos and fast-paced video games, LCDs suffer from the ghosting effect.
* Viewing angles. Looking at an LCD monitor from an angle causes the image to look dimmer or even disappear completely.
* Colors. The color accuracy of an LCD monitor does not match that of a CRT monitor's.

What is the difference between LCD TV and LCD monitor?

Q. I want to purchase a LCD TV/LCD Monitor for my PC. Which should I purchase - LCD TV or LCD monitor. Is LCD TV harmful for eyes as compared to LCD Monitor? Which is the best one LCD TV or LCD Monitor?

A. A LCD MONITOR does not have a built in tuner...

That's the ONLY difference between the same model...

They are great if you know you'll be connected to Satellite or Cable and using their HD Set top boxes for the next 10 - 15 years.

If you're unsure, get the LCD TV.
If it was harmful to the eyes, do you think they would be allowed to sell it?

You can test a LCD TVat this site

Can LCD monitors damage the skin around your eyes?

Q. I have an LCD monitor and I wanted to know if it can damage or affect the SKIN around your eye in any way? Like for example can it cause premature eye wrinkles, or thin down the skin around it, or anything similar?

A. LCD monitors are the same light as a lightbulb...just a bit more intense and controlled to display images. Unless you're squinting and straining to read something on screen then you're fine.

What is the diff between a TFT-LCD and LCD monitors? Which is good for eyes in terms of long working?

Q. I wanna buy a 19" LCD monitor and currently weighing between HP and Samsung monitors. All HP monitors are called LCD monitors as per the package details as well as per their website, while all Samsung monitors are called TFT LCD Monitors. I am a bit confused, as I work a lot on PC, I would like to protect my eyes and health. Can someone help me with correct answer?

A. LCD monitors use Liquid Crystal Diodes.

TFT is an LCD monitor that uses Thin Film Transistor technology.

Other types are:
TN+Film - Twisted Nematic
IPS - In Plane Switching
MVA - Multi-Domain Vertical Alignment
PVA - Patterned Vertical Alignment
S-PVA - Super Patterned Vertical Alignment.

TFT is the most common today, and LCD is accepted as being TFT-LCD. Usually you only see a differentiation if it's one of the other technologies. The other types all have their advantages and disadvantages, but TFT is the cheapest to manufacture today.

For your eyes, you want an LCD. LCD's are on, and change when they change vs. a CRT which has a refresh rate. In a CRT, the phosphorus is charged and glows, but then dims very quickly. The refresh recharges it, but there is a dimming and brightening affect. The higher the refresh rate, the less noticable it is to you.

Within an LCD, if cost is no object, you want an IPS (better) or S-PVA (best). They will have the highest contrast ratios and brightest screens. Be prepared to pay, and pay well for this luxury though.

What's the difference between the LCD and the old ones monitor?How fast does the computer spoil our eyes?

Q. I would like to know the difference between the LCD monitor and the old ones,then i'm wondering if my eyes will be spoiled by computer cause i spend sometimes in computers,if so how fast can it spoil my eyes??

A. Flatscreens and LCDs certainly do provide a clearer picture, and I do prefer to use them over CRTs except when using my 3D goggles which only work on CRT monitors. If you plan on watching a lot of movies or playing games on your computer, then an LCD is worthwhile, purely for the quality of picture.

Generally, computer use will NOT affect your eyes. I've been staring into a computer screen for the better part of hmm... about 700,000 hours over 12 years. Probably a lot more, definitely not any less.

Most of that screen time was spent in front of CRT monitors. I only started to experience problems with reading about 2 years ago. My optomitrist says this was more due to having a lazy eye as a child that wasn't picked up. I now use glasses for reading books but can get by fine without them normally. If it were true that my eyesight had been affected by CRT use, then I would expect my dominant eye to be just as, or more, troubled as my non-dominant eye. However I still maintain perfect vision in that dominant eye, even though I use both to look at a screen. Eye problems run in my family, so all things considered, I don't think there's much of a correlation.

I know people who've spent just as long in front of computers as I have and they can see perfectly, if not better than most. Skin is also unaffected, but can get a bit blotchy if you stay up all night on the computer... as it will if you stay up all night doing anything else.
The other thing that makes me suspicious of CRTs causing eye problems is that when you use a computer your eyes get a good work out, reading small print, large print, looking here looking there.

If you're concerned about eye strain, try turning down the glare on your monitor (brightness or gamma) and switch to a less goudy colour scheme (ie no bold reds and contrasting greens). If you are further concerned, try doing simple eye exercises such as focusing on your finger close in and then far out, with each eye, one at a time.
