Question about Monitors?

Q. So i've been looking around for the best monitor to buy for my pc i know tons about computers etc but i know nothing about monitors, but i've nailed it down to two monitors left either the Acer S243HL 24 > http://www.newegg.com/Product/Product.aspx?Item=N82E16824009206 or the HP 2510i http://h10010.www1.hp.com/wwpc/uk/en/ho/WF06b/382087-382087-3284302-215012-215012-3757979-4128855.html

So my question is based on peoples knowledge of monitors which is the better one to buy ( money isnt a problem ) i want to know which specs better which one has a better picture etc based on reviews knowledge and if you have one of these tell me how good you'd rate it

Most helpful answer wins thank you.

A. Manufacturers tend to exaggerate the contrast ratio of the LCD panel in order to suck consumers into purchasing it, but in reality you cannot really see the difference between say, a 10,000:1 dynamic contrast ratio between a 20,000:1 DFC (even though the numbers seem to suggest a significant difference)

There are currently 2 types of LCD screens -- CCFL and LED backlit ones.

CCFL is the most commonly used backlighting tech, which is just cold cathode light tubes

LED backlit panels are less common, but have the benefit of brighter displays, better contrast ratios, use less power but they cost a little more compared to normal CCFL panels.
There's probably a $30~40 difference between the 2.

The other spec you look at is the response rate. Most monitors have a 5 millisecond response (5ms) but some higher end ones are rated at 2ms.

However you will also see a specification along the lines of "2ms GTG" which means "grey to grey"
These are not true 2ms panels -- it just means if a pixel is grey it takes it 2ms to change to a different color and then back to grey. So thus -- it's a 2ms display that most of the time that only does 5ms.

The response rate of the monitor is only important to FPS gamers and people who watch sports on their screen -- but in typical usage you never really notice 2ms vs 5ms.

In terms of LCD display quality, you have to look at who manufactures the LCD panel. Acer for example, does not produce LCD panels, but they actually use LG branded panels but produce their own electronics.
Samsung arguably comes up with the best panels in the market, so if you want a good quality monitor, just buy a Samsung brand.

23 inch, 2ms response, LED backlit $219 (I recommend this monitor)

24 inch, 5ms response, CCFL backlit $229

which is better LCD or TFT monitor???
Q.

A. The term TFT and LCD has been loosely used.
TFT stands for Thin-Flim-Transistor and LCD, Liquid Crystal Display. They are entirely 2 different items. TFT is used to control the LCD in the display panel and for this kind of display, we call it TFT-LCD, which we see LCD TVs and LCD Monitors. TFT-LCD are called active matrix LCD http://en.wikipedia.org/wiki/TFT_LCD

Passive matrix LCD are those used in calculators, watches and older monochrome monitors and older laptop screens. http://en.wikipedia.org/wiki/Liquid_crystal_display

We could have different types of TFT-LCD panels with different construction technology. http://www.pchardwarehelp.com/guides/lcd-panel-types.php. S-IPS has been considered to be a better panel.
