LG Introduces 23-inch 240 Hz IPS LCD Panel for Monitors
LG Display, a leading innovator of TFT-LCD technology, announced today that it has launched the 23-inch 240Hz LCD for monitors (dual monitor and TV use) that refreshes at a rate of 240 frames per second to deliver clear picture quality with no ghosting effect.
The industry have been engaged in a heated race to improve the motion picture response time (MPRT), unveiling products with refresh rates of 120Hz or 240Hz which are respectively twice and four times as fast as broadcast signals (60Hz). However, the technology has mostly been applied to LCD panels for high-end TV panels that are 40-inch or larger. This is the first time that 240Hz technology was applied in a 23-inch product under mass production.
The full HD 23-inch 240Hz LCD panel was developed by combining 120Hz technology (refreshes 120 images per second) with scanning backlight technology which enables a backlight to be repeatedly turned on and off.
Boasting a refresh rate that is four times higher than regular 60Hz monitors and twice as high as 120Hz monitors, the 240Hz LCD significantly reduces motion blur to make it less strenuous on the viewer's eyes and deliver true-to-life images.
LG Display's copper bus line technology was employed for fast processing of vast amounts of image data. As a result, the product has an motion picture response time of 8ms (millisecond), akin to a large premium TV, to eliminate motion blurring for fast moving images. Moreover, the 240Hz LCD features IPS (In-Plane Switching) technology for no distortion in color or images from any viewing angle which makes products ideal for TVs.
In the past, monitors in the 20-inch range were mainly used for word processing, but expansion of the multimedia environment has extended their application to games, videos, and even second TV sets. The 23-inch 240Hz LCD panel from LG Display should allow consumers to enjoy vibrant images and picture quality they expect from a large-size TV on their monitor or a smaller, second TV.
Ha Hyun Hwoi, LG Display's VP and head of the IT business unit, noted, "This product was designed to meet expectations of consumers who are already used to superior picture quality and high motion picture response time. LG Display will continue with efforts to introduce products that deliver new value to our customers and consumers."
According to research firm DisplaySearch, the market for 26-inch and below LCD products, which are primarily for dual monitor/TV use, is expected to grow by more than 20% from 49 million units in 2009 to 60 million units in 2010.

if your eyes could only see 30, you would NOT be able to see ANY difference at all.
The one in this topic is IPS. IPS is what the Dell and Apple 30inch displays are, along with some big screen TVs (others are PVAs, Samsungs own high quality panels (there are others too)). TN film is what you see on most PC monitors, except for expensive displays.
IPS is the king for quality LCD panels, so a 120Hz IPS is actually a great thing.
pity its not a bit bigger, however.
And while related in terms of framerate, crt refresh flash is a little different than pure frame rate as well. I also get a headache at 100hz on a crt, but I can't see a difference between 80 and 100fps on said screen.
LCD monitors aren't susceptible to that type of flash tho, so frame rate and refresh rate are more closely related to the human eye.
In other words, nothing is set in stone. It's pretty much all hit and miss on a per person basis.
contrary to popular opinion i find it worse in RTS games - the high speed scrolling in combat doesnt bode well for jerking.
I don't play RTS, so I can't relate. I do know my sensitivity depends heavily on the games I play tho. On Borderlands, anything below 55 or 56 is horribly jerky, but I have played other games at 45fps, and they still played smooth.
Anyway, It is DEFINITELY from flicker or low framerates for me. I can play all day on at 60fps on an LCD, or on a high refresh rate (over 100Hz) CRT, without a headache at all.
I've tested this out on myself to make absolutely sure what was causing my headaches. If I drop the framerate on any type of screen, I have a headache in minutes, if I drop the refresh rate on the CRT but keep the framerate at 60, I get a headache in minutes. This is a 100% fact for me in particular. I can't comment on anyone else tho.
The human eyes frame rate actually varies, if dark conditions it's lower, if your focusing on a single object in a scene it can be higher, peripheral vision has a high "frame rate" than the rest of the eye too.
There has been studies that have shown fighter pilots to be able to see a single flashed image up amongst some 200fps footage, if we only saw at 30 frames it just wouldn't be possible.
You can test your eyes own frame rate by making some 30 fps videos, some 45fps and 60 fps and so on and so on, and get a friend to randomly choose a frame to put a disgusting picture :laugh:
It's all situational and dependant on how "aware" the individual is : ].
Sorry for poor sentence structuring, not my forte :laugh:
Hopefully this new monitor tech reduces eye strain. I might end up getting one of its slightly larger variants.
Fps lower than 40 gives me a migraine, PERIOD. The ONLY exception to this is Crysis.
I can play for 8 hours straight at high fps and high refresh with no headache, but I get a migraine after only an hour at low refresh or framerate.
My migraines ARE NOT caused by gaming for too long.
So please, kindly STFU, and step out of this thread, until you actually learn how read, comprehend, and then post, because you clearly have no clue what the hell you are talking about.Nope, not that lucky at all. I still get one or two a month. Sometimes they last for days. I live off of Fioricet during those episodes. It's the only way I can function.
That's why I'm so picky about framerates. I prefer to avoid migraines at all costs. lol.
Ummm, no, that's not how it works. Low fps can cause eye strain, which in turn, leads to migraines. I'm not the only one I know of that this happens to, either.
So again, I ask you to please know what you are talking about, before you post.
