Damn... Bought a new LCD (IPS) HP 23CW and this shit happens...
Sent it back for replacement, or IPS problem like this is common? This is really sucks...

The cool tone look like IPS glow to me, but the yellow one seems like more a backlight bleed.
IPS glow - it changes when look from different angle. From the picture, it doesn't seems severe.
Bleed, same throughout no matter how you look at it.
IPS tends to have so called IPS glow, it is the nature of the panel, just more and less.
But, from experience buying a number of monitor (all IPS based due to better colour and viewing angle for office usage), I find that those more expensive IPS panel have less of it.
I find that IPS glow tend to happen more often in monitor instead of LCD TV, may be cheaper panel used in monitor?
I have a H-IPS LCD TV years ago, no glow, no bleed at all.
Since manufacturers change the blacklight from CCFL to LED, I also find the blacklight bleeding start more common at corner/edge of monitor.
I find LED light is not as good as CCFL, even for ordinary room lighting.
LED light always seems "odd" to me, not that natural.
