I do not know what will I buy LCD Samsung or LG?

Question

Which is the difference between contrast of 2000:1 or 3000:1?is it important?

Answer 1

samsung all the way . 3000:1 is better than 2000:1

Answer 2

One has to consider 3 critical aspects of this technology while taking a decision

Contrast Ratio:
All LCD screens get their brightness from lighting behind the actual LCD films. This light has the tendency to wash out the colors and provide a close approximation on most colors. The contrast ratio of a LCD flat panel is the rating of how distinguishable various shades of color are. The higher the contrast ratio of the screen, the better the color representation is by the monitor. When comparing monitors try to find two models of similar size from the same manufacturer with different contrast ratios. The screen with the higher contrast ratio should have better over all picture quality.

The best brand for LCD's is Sharp Aquos with dynamic contrast ratio of 6000:1 on 42 inch screen.Samsung has 4 models in 40 inch size having 3000:1,4000:1 and 5000:1

Viewing Angles:
LCD's produce their image by having a film that when a current runs through the pixel, it turns on that shade of color. The problem with the LCD film is that this color can only be accurately represented when viewed straight on. The further away from a perpendicular viewing angle, the color will tend to wash out. The LCD monitors are generally rated for their visible viewing angle for both horizontal and vertical. This is rated in degrees and is the arc of a semicircle whose center is at the perpendicular to the screen. A theoretical viewing angle of 180 degrees would mean that it is fully visible from any angle in front of the screen. A higher viewing angle is preferred over a lower angle unless you happen to want some security with your screen.
Both Sharp and Samsung has viewing angle of 178 degree

Response Times:
In order to achieve the color on a pixel in an LCD panel, a current is applied to the crystals at that pixel to change the state of the crystals. Response times refer to the amount of time it takes for the crystals in the panel to process each frame. A rising response time refers to the amount of time it takes to turn on the crystals and the falling time is the amount of time it takes for the crystals to to process each frame. Rising times tend to be very fast on LCDs, but the falling time tends to be much slower. This tends to cause a slight blurring effect on bright moving images on black backgrounds. The lower the response time, the less of a blurring effect there will be on the screen

Sharp has a response time range of 4 - 6 mili second per frame compared to samsung at 8 ms per frame

Answer 3

Contrast is the ratio of the blackest black vs the whitest white.
Yes, good contrast is important, especially in LCDs (Plasma have a contrast of about 10,000:1)

The mumbers you cite are for "dynamic" contrast, which is usually 3-5x higher. Dynamic contrast is the darkest black with the backlight way down vs brightest white with backlight way up. So make sure to compare apples to apples.
(In other words, a 3,000:1 dynamic contrast corresponds to about 600:1 -1,000:1 contrast)

Sharp never advertises dynamic contrast, HP and other advertise both.
The state of the art for True contrast is about 1,200-1,500:1

Answer 4

personally i would stick with samsung they are the most reliable and give the best performance but i would go with 2000:1

Answer 5

Both brands have a HD C.R.T. and each is pretty cool. I like the LG more, though. Good luck.

Allahu Akbar

Answer 6

olevia is alot cheaper and im totally in love w/ mine. i think its worth u doing some research and pricing. newegg.com has a great sale on the one i already have. hope this helps!!
