I just thought I'd write a quick guide for people who are thinking of upgrading their monitor. I am by no means an expert so other people feel free to add or point out any mistakes in my post. I did this research as I was looking into buying a widescreen monitor myself as I am upgrading from a CRT.
They way I understand it is there are 3 popular types of TFT panels
TN is the most common but also the worst quality ie poor colour and viewing angle. Though do have the highest response times.
+ improved colour and viewing angle
+ best quality and viewing angle
-poorest response times
If you wish to use your monitor for all round role TV, DVD's & games your are better off (in my opinion) of buying a monitor that has a S-PVA or S-IPS panel.
With S-PVA or S-IPS you can defiantly see the difference in quality and difference in response times is not that much. You do pay extra for this of course .
If you wish to hook up your games console/dvd for high def you need to check it is HDCP compatiable. More information on this can be found here:
