Artifacts in dark scenes

I'll try to keep this brief.

 

I've got a PB298Q.  It's an IPS panel.

 

In dark scenes, there's visible artifacting.

 

It's hard to explain, but if I have a character with a light radius (think Diablo) and it fades out into blackness, there will be this horribly artifacted circle around the transition where it goes black.  It looks like low bit color.  If I change the preset display modes around, the severity of it changes; even disappearing in certain instances (but hurting the rest of the image overall).

 

Edit: Got some pictures.

My old monitor (HP f2304, also IPS) did not show any artifacting in dark scenes; they just weren't very good because of it being an IPS panel and having a CCFL backlight, so blacks couldn't actually be black (I assume).

 

I expected a newer panel with LED backlighting to have better black levels.. but it seems either ASUS is terrible at build quality or 21:9 have backlight bleeding issues, as not only does it suffer this artifacting issue, but the backlight bleeds (or it's this 'IPS glow' I hear things about) and makes dark scenes look greyed out, similar to my old monitor (though I can see a tiny bit better).  Edit: Probably just "IPS glow".

 

I've not been able to find any information about this on the net.

 

Has anyone else experienced this or have any idea why this happens?  I assumed it was because my old monitor was a high bit panel compared to this one, but reading has lead me to believe that even a 6bit+FRC panel should be very similar to 8bit and the same for 8bit+FRC to 10bit.  I THINK this monitor has an 8bit panel, but I need to look it up again.  This may be a 'color gamut' issue instead, but I don't know much about that.

 

I bought this solely to game on, but it's honestly been a bit of a worse experience due to how awful the image looks in dark scenes.  21:9 is really nice.. for gaming, but not with these issues.

I have the same issue on my BenQ 24XL11T,  and the issue, I guess, is very simple to understand  : that's a TN panel, and they suck at color reproduction. Basically my dark part are always a little bit reddish, even after some careful calibration. And transition from dark to anything lighter will display that weird, ugly greenish thing you experience.

 

Only advice I can give is to get some Spyder calibration tool and spend some time trying to get it right. I mostly got rid of the green effect, but the red tint remains. I just can't watch movies like Gravity on my BenQ, which is why I'm trying to get a good IPS one.

The PB298Q is an AH-IPS panel.

 

I remember reading it being an 8bit panel too, but I can't find that information again when searching now.  Was worded poorly. True 8bit according to ASUS.

 

So.. that wouldn't be why.

 

I have yet to actually contact ASUS because, well, not only is their support system terrible, but their customer support is even worse.  Sent a ticket, waiting on a disappointing response.

 

I doubt the rep I talked to over on [H] will respond after all these years, and am wary on PMing him again out of the blue.

 

So far, no one knows what could possibly be the issue.

 

 

My old monitor isn't calibrated beyond the OSD controls; same as the new one.  I don't believe calibration with an expensive hardware tool will do anything as this seems like a panel design issue; which no one has seemed to point out in the very few reviews of the monitor there are.
