IPS and TN

Is there anyone who can explain the difference between IPS and TN screens at 120hz ? (Simplified please)

yes...there`s no such thing as a 120hz ips screen is probably the biggest difference ;) .ALL 120 hz screens are TN and likely to remain that way for the foreseeable future unless someone spends a lot of money and time getting the inherently "slower" ips tech upto TN levels of response.This is unlikely to happen cos in the next few years hopefully OLED screen will become more prevalent.Though it`s probably around 3 years at very best before we are likely to see remotely affordable OLED screens.
 
OK now I am more confused.
Im looking at buying a 24" screen.
I have seen a BenQ 120Hz LED for about £260ish
Am I likely to be getting a low grade monitor?
I don't have a lot to spend on a screen or should I go smaller but better quality?
 
Oh no... The weight of expectation has overburdened me. :D

I don't want to add to your confusion so I'll start from where everything left off. The BenQ XL2410T is an example of a 120Hz LCD monitor - for reasons such as those highlighted here this uses a TN panel rather than an IPS panel. As I think you have understood from your research this is what you may be referring to as the 'low grade' element of the monitor. You can understand some of the limitations of the monitor by reading reviews such as this and this. The 'LED' element simply refers to the backlight which shines through the 'pixels' (which are basically colour filters on an LCD) - it doesn't really have much of a bearing on image quality (more here).

OLED monitors, on the other hand, are something to look forward to for the future. They do away with the backlight entirely and once the technology has been refined for the mainstream will provide a big jump in pretty much every aspect of image quality that you could ask for.
 
Sure someone will answer your question much better than I can.

IPS monitors generally more expensive and have wider viewing angles. The response times are generally slower than Tn panels. Some panels can ghost.

TN panels have narrow viewing angles and faster response times

That said I have a standard TN panel and an IPS panel and much prefer the ips panel.

The Tn panel suffers from light bleed in the corners, the IPS panel doesn't.

Never used a 120 TN panel mind.
 
So it may be worth sticking to a decent IPS 60Hz LCD panel which will give a better picture than a 120 Hz TN LED panel. I will be sitting head on to it so viewing angle is not really much of an issue).

Colours also show variation across the screen on a TN panel. This is illustrated nicely by this page which we try to use in our reviews to help explain differences between panel types: http://www.lagom.nl/lcd-test/viewing_angle.php.

Hi everyone!

This is also what I thought, but it appears that this is not the case - soon there would be a 23" Full HD IPS panel that runs at 240 Hz:

My guess is that it's only a matter of few months till we see commercial monitors that use that 240Hz IPS panel.
