How are they for Windows & general PC stuff?
I know you are angling for a new monitor(s) if you ignore the model type for the moment after using my UW 34" coming from 32" 16:9 for a couple of days I`m slowly getting used to it. Things I like the extra screen space for gaming, widescreen movies fill the screen no black bars (if in the right ratio). I do find I have to move my head more slightly when using say Outlook. My slouch position is 80cm from the screen, my proper situp type is 60cm from screen. I have found due to the extra width my slouch position is a lot more comfortable than with the 32" screen.
I sometimes do video editing and my problem has always been width of screen and this one also solves that issue. For general Windows and PC stuff its as good if not better than 16:9.
With this particular model I can see why some people dont like it as the whites are not quite white and I only noticed it by comparing it to my phone screen and my wifes AOC screen. It has took some fiddling to get it how I want. I have since discovered there is some IPS Glow at certain places particularly the bottom left corner which I can see now why this was returned for B Grade. However I cant see it during the day I only noticed it last night when I was checking it again a black screen. I still think I`m going to keep this even despite that because the price I paid was very good and I can live with the IPS Glow.
With regards to the OP its not a simple case of IPS v LED as IPS is a panel technology and LED is a backlight technology.
Monitors on the forum are generally differentiated between IPS v TN v VA
Personally I prefer IPS for the colour reproduction, sharpness and viewing angles. Some people prefer VA for the deep blacks. Realistically your choice is between IPS and VA but you will only know which you prefer by visually looking yourself.
