Which contrast ratio is better?

[orb72]

How does a monitor with a "digital fine" contrast ratio of 50,000:1 compare with a monitor listing a "dynamic contrast" ratio of 5,000,000:1?

 

[rofl_my_waffle]

Both are actually dynamic contrast ratios since any TN panel can only ever do 1000:1 static contrast.

Don't fall for dynamic contrast, it is only a marketing gimmick since the technology is terrible.
Dynamic contrast takes manipulates backlight brightness to produce blacker blacks. Which sound good on paper but terrible in practice.

When the backlight is lowered, everything on screen becomes dimmer. Even things that are suppose to be bright. In very dark scenes you may not be able to see stuff like gunfire and lamps. In video games enviroments change frequently and this can cause the brightness of a monitor to flicker to constantly compensate for the darker or brighter scenes. Also in many scenes there is a balance of dark and bright pixels on screen and dynamic contrast can't do anything for those situations.

Assume all LCDs are 1000:1.

Thanks for your reply. Very informative. Basically what I'm looking for is a monitor with the most gradations in tone and color depth available. I work with graphics apps and want to be able to see all the variations in detail that anyone else would see with their monitor.
Thanks for your advice. (Leaning towards a full hd LED lit screen right now.)

Which LED monitor are you considering. Those offer better whiter whites because of the LED backlight. Very good monitors. However I got the Acer 243HL which turned out to have really bad color saturation at 68%.

Had to let it go for an IPS panel which has 115%, no LED backlight though but doesn't matter as much.

Well, possibly the LG E2350V. Just came out. It's on Best Buy's web site, but could not get my tech questions answered at lge.com because they said it was an international model. Strange.
Also considering the Lg W2486L, but contrast ratio only 2,000,000:1 vs 5,000,000:1, but you've already answered my question about that.
How are those ACERs? What's an IPS panel?

 

[rofl_my_waffle]

Those acers are not good.

There are 3 types of LCD monitor panels. TN, PVA, and IPS.

TN panels are the cheapest to manufactuer and dominates LCD markets right now. They have very very fast response times but not better than PVA or IPS panels in any other situations. These can't display 16.7 million true color from your graphics card. They mimick some tones by flashing between dark/light tones to produce a medium tone or set dark/light pixels beside each other to produce a medium color pixel, also known as dithering and frame rate control.

PVA panels are what TVs use and some monitors. They offer better color and can display true color from your graphics card. These have very good black levels and doesn't have as good response time as TN panels.

IPS panels are the king of the hill in terms of monitors. These offer best color accuracy and saturation. Response time is 5ms for the pastest IPS panel which is pretty good still. The only real drawback is price. A 24" IPS panel would have a considerable price premium.

I got a LG IPS panel right now because my acer was disappointing for color.

LED monitors dont have a back light LED monitors use LED lights instead of a florescent back light.

LED backlit monitor don't really offer any substantial difference in terms of color quality / white light compared to florescent backlight.

For sheer quality and color accuracy the NEC LCD2490WUXi it the best normal gamut monitor you can buy. The larger LCD2690WUXi2 is amongst the best wide color gamut monitor. Those monitors are also rather expensive (in excess of $1,100). They are monitors for the graphics professional and have additional electronics such as a 10-bit or 12-bit color look-up table (LUT) used for even fine color accuracy and ColorComp to ensure consistent color tones. If color accuracy is the absolute highest priority purchase the more expensive SpectraView version which comes with the SpectraView hardware colorimeter.

The Planar PX2611w is an alternative to the more expensive NEC LCD2690WUXi2 and can be bought for under $800 shipped. Same H-IPS panel used in the NEC, however no extra electronics or colorimeter. The Planar also makes an excellent gaming monitor due to the fast response time of 5ms and less than 8ms of input lag. The extra electronics in the NEC LCD2690WUXi2 for color accuracy causes input lag to be about 32ms; 4x greater than the Planar.

That's a contradictory statement.

 

[darthlaidher]

That's a contradictory statement.

how is that contradictory a LED tv/monitor doesnt use cold cathode fluorescent lamps like traditional lcds

 

[jaguarskx]

The LED itself is the backlight.

 

[darthlaidher]

The LED itself is the backlight.

but not the same as the traditional lcd

 

[jaguarskx]

It is still called backlight.

Interesting. Thanks. Is the 2353V by LG going to be PVA or IPS and will it display in true color?

I'm interested in the color accuracy of these monitors but don't want to have to fiddle with controls to get it. Can you recommend same quality monitors with hdmi inputs and vga input? The planar PX2611w doesn't have hdmi input.

 

[orb72]

To be more specific, I'm interested in the Planar PX2611w wide color gamut and H-IPS panel similar to the NEC LCD2690WUXi2. Looking for one in the 23"-24" range just like it. Can you recommend?

HDMI = DVI without sound. So it doesn't really matter unless you want a HDMI to plug in a PS3 or something.
