Problem is you cannot get IPS screens with a good response time. All the ones I have owned before have has some level of motion blur which is why I now use an Asus 120Hz screen.

I think at the end of the day I would be happy with the upgrade and isn't that what it is all about at the end of the day?
but your graphics card can also sync to 60, 40 or 30Hz if it can’t manage the workload. A 60Hz screen can only revert to 30Hz, a much more jarring reduction in frame rate.

I don't think this works the way you think it works. What are you trying to express here?
V-Sync drops to the next round fraction of the refresh rate.

It does? News to me, and I've written software that does it.
I thought it just held off updating (by buffer-flipping, usually) the display memory until it had finished sending a frame to the monitor. That may mean that you end up with some round fraction of the monitor's refresh rate, but just as equally it may not.
In practice you end up with a fairly staggered output of frames as the ability of the graphics board to deliver frames and the ability of the DVI link to send them to the display go in and out of phase.

The one thing that really bugs me about mine is the viewing angles, as far as I can tell my colours are still ok but my backlight went about two years ago and I had to change all the capacitors in it. Your right that if your happy with your purchase at the end of the day, then that's all that matters. And you could always run your current screen as a second monitor if you buy a new one or stick it in the loft as a spare.

When I upgrade (which is being timed with my eventual new gaming rig build later this year) I wish to upgrade both monitors to the same model. I'll go with the Dell U2414H unless a review shows me a better monitor under £200. Another reason for the Dell is the 6mm bezel. :)

As Dave says, the viewing angles on the TN panels are really poor compared to a nice IPS screen, and the extra screen real estate is great for general use. However, the single biggest difference for me was the brightness and colour reproduction of the Dell compared to the Samsung - it was staggering :D My U2412M is sitting at 30% brightness and is probably still twice as bright as the 226BW at full blast. When I had the two sitting side by side, the Dell seemed far too blue at first, but that was just because the Samsung had become so yellow over time that my eyes thought that white was actually meant to look beigey yellow.
TLDR: new monitors are great, get one!

Removing the back of the U2412M confirms that the screen is using LG.Display's LM240WU8-SLA2 panel which we will discuss a little later on. This is a new IPS + W-LED module which we have not seen used elsewhere yet.
The Dell U2412M utilises an LG.Display LM240WU8-SLA2 e-IPS panel (datasheet link) which is capable of producing 16.7 million colours. The panel itself actually uses a 6-bit colour depth with Advanced frame rate control (A-FRC) to produce the 16.7m colours. This is different to regular 8-bit IPS matrices, but this is a measure taken to achieve a lower price point for these modern lower-cost displays. Studying detailed information from LG.Display's datasheet confirms the panel is indeed 6-bit + A-FRC.
The Dell U2414H utilises an LG.Display LM238WF2-SSA1 AH-IPS panel which is capable of producing 16.7 million colours. This is achieved with a 6-bit colour depth and an additional Frame Rate Control (FRC) stage (6-bit + FRC) as opposed to a true 8-bit panel. This is a measure commonly taken on modern IPS panels, and the FRC algorithm is very well implemented to the point that you'd be very hard pressed to tell any difference in practice compared with an 8-bit panel. The panel is confirmed when dismantling the screen and is slightly different to that used in the P2414H model (LM238WF1-SLA3):
Skipping a scan trigger of a 60Hz monitor results in an effective frequency of 30Hz.
