Isn't that just backlight bleed?
I have a slight bit brighter edge fading to normal brightness over a few mm on the LG 43".
I think is pretty normal esp for IPS.
Only really notice when there is a white window at the edge & I'm actually looking at that edge, its off in the peripheral vision most of the time so I don't notice it mostly.
But its more than on the Dell 30", have to look real close to spot it on that monitor.
Dark room watching a movie I have noticed blacks are kinda grey, normal for IPS but a little more noticeable than my Dell, probably partly because the black bars are more area on the bigger monitor, the 43 is a bit brighter & colder colour temp though (haven't made too much attempt to match with the Dell) & thats probably also somewhat related.
Right at the edge is also brighter next to blackbars but it seems to fade in about 1mm instead of several mm on white window.
Unless its a very dark scene I don't really notice either when I'm actually looking at the movie.
its not backlight bleed, as it makes "darker" instead of "whiter/brighter".
here's the issue
See on the left of "https". its darker, and you can see that there's an optical illusion making it seems there are pixels on top of the shadowed/darker areas, there's also looks as if there's a gap on the left. Making it looks like its curved away from you, like a Samsung phone.
not an issue when viewed straight on
(ignore the chromatic aberration, its due to the horrible google pixel 1 camera)
EDIT:
btw LG RGB IPS monitor and TV also have issues in showing blues. Where a small population of people can see the blue became full of vertical lines.
as for LG RGBW IPS monitor and TV, it have issues in showing mesh-like diagonal lines when showing yellows. Also only can be seen by a small population of pepole.
LG OLED (including the latest EVO panel) also have issue (color bleed on yellows) that only can be scene by small population of people.
as far as my experiences, these issues are not in
- Samsung VA panels
- TCL VA panels
- Changhong IPS panels
the color bleed issue also happen on Samsung AMOLED panel. But only for low resolution amoled, like on 720p samsung AMOLED phones. And only on blacks instead of yellows.
