I have personally bought and tested five different Korean monitors in the past month and one thing I can say is that these monitors are EXTREMELY inconsistent.. which makes sense because they are inherently flawed panels. I am not here to tell everyone which display is better but rather, I was just sharing my experience
PS - I have a color meter on the way next week so I'd be happy to share my results from there but as I said, the colors already look great on the DS270.
Funny i just found this regarding the monitor you like so so much , qnix
The side effects of overclocking the Korean PLS monitors are:
1) Gamma shift - commonly described as darkening
2) Panel uniformity - where the left side and right side of the screen are not the same brightness
3) Image retention - experienced generally with objects that are displayed on a monitor for extended periods of time, seems to be more of an issue to those who leave their monitors on or are editing documents for long periods of time
You can reduce / eliminate (most probably reduce the gamma shift and Image retention) by keeping the pixel clock below 450MHz, which is what the EP269 controller used on these (even the Catleap) Korean monitors is natively capable of.
You do this by editing the other numbers and not only the refresh rate, driving down the pixel clock for a particular target refresh rate. Or, working in reverse, achieving the highest refresh rate for the lowest pixel clock while keeping the pixel clock around or below 450MHz.
There is an absolute necessity of having a colorimeter / spectrophotometer (if you can afford it) when doing color-critical work. The gamma shift can easily be corrected with color calibration; however, if you desire the best results with the least correction possible, color-critical work could simply be done at 60Hz and whatever else you do, at 120Hz.
@HyperMatrix: I've been wondering for a while, worried about the side effects of overclocking the Korean PLS monitors. What exactly are the side effects of overclocking the Korean IPS monitors such as the Catleap, besides the scan line brightening that you speak of?
I wonder how the panel itself could be affected by overclocking (such as panel uniformity issues) when the display controller, the EP269, is used across all (AFAIK) overclockable Korean monitors.
There really should be a detailed PCB comparison between the overclockable monitors with the aim of understanding what's really going on. I'm willing to do so with my monitor when I receive it. Whoever is willing to cooperate,
