BIG 4K - LG vs Samsung vs Wasabi Mango

igluk said:
There is quite a difference with contrast and a camera DOES pick a difference in black depth, and the image washes out slightly with lower contrast.
What is true though is it barely affects colours and bright scenes.
I can set my monitor to IPS black levels, at ~105cd/m² and all other things being equal:

Wouldn't it wash out in the particular scenario because the contrast has been reduced and the lights are off? How is the difference when in a lit room? I can definitely see gamma shift in the picture you've used to compare with ToastyX's.

Side note: What is your gamma set to?

I see similar gamma shift, plus the picture must be taken from normal viewing distances. Why is the picture so tiny, and how far away were you?

~70cm without zoom, if you click the thumbnail it links to big image.
the gamma shift is there alright, especially in the mountains when shifting position.
the camera can't capture it as intensely as on ToastyX monitor, even though I intentionally overexposed a bit, so the effect is probably weaker on newer panels
also the far right of the test picture has a brighter copypasted area, it's not fully symmetrical.

And is it a MVA or MVA+ panel beacese i tested a MVA+ last year and i was really disappointed with the picture quality.

its MVA+
the old 5000:1 do have better black uniformity indeed, and at higher brightness the MVA+ get silvery-purple glow from angle
not sure about coating and colours of the old ones but they weren't very accurate afaik, maybe some oversaturation as well

in a lit room the difference is reduced a lot obviously. the gamma is set to around 2.2-2.3

I will concede that the effect appears to be reduced on newer panels, but it still illustrates the same issue rather clearly (or at least it does based on your picture.) All I've been trying to get across the past couple of posts was that the effect will be much greater on a larger panel. Of course, I always seem to be bombarded with forum-goers that want to inject their ignorant opinion into matters with no evidence to back it up (not you, of course, igluk -- I like you.) NCX's post sums up my experience with the issue.

I don't see why anyone would ever want a large VA panel (or even a 24" for that matter; though, you've claimed to overexpose the shot) as a monitor. It would be as if the default or calibrated gamma wouldn't even matter.
 
@Nikyo
You a little bit outdated when it comes to VA panels. The gamma shift depends on the VA panel quality and not on the panel size.
The Philips BDM4065UC (40" VA) has less gamma shift than my GW2450HM (24" MVA) Monitor. And again i take gamma shif over IPS glow, no one whats to watch a TV/Movies with glowing borders and corners.

@NCX
I don't really notice any color or black differences when sitting in a bright room or dark room.
If the Philips BDM4065UC would not be so big then i would buy it immediately.
I'm still haven't found a successor to my GW2450HM (MVA) i even bought the new GW2760HM (MVA+) and i was really disappointed at it because everything looked dusty probably because of the carpy AG counting (not sure).
If you think i would by happier with anoher Monitor (preferred 27"/1080+) then i would be the last one to say no to give it a try. But the IPS glow on the 2 IPS Monitors i tested so far really pissed me off in dark games and watching movies.

Good lord.

Let me be clear: VA gamma shift and contrast loss will result in a similar form of glow and desaturated colors the further we move away from the middle of the screen (in reference to our viewing distance.) I'm not going to humor your comments further, because I'm 100% certain you do not understand any of the information I, igluk, or NCX have posted. And to remind you, this thread is for large monitors, not your 24" which will suffer from the issues posted much less than a larger panel. Your claims are not substantiated at all.

Side note: The GW2760HM uses a lighter matte coating than the GW2450HM.
 
VA gamma shift does not produce glow on my VA Monitor.
Here is an example on what i experienced.

And if the GW2760HM is really using a lighter matte coating as the GW2450HM then i'm really speechless why the colors on the GW2760HM looked so dull. I think this cannot be only because of the 2443:1 vs 1914:1 contrast ratio.

@S0L0
If you buy a Korean TV/Monitor then keep in mind the import Tax and take a good look at the return policy.

Time to exit the thread. You clearly don't understand what is being discussed and your opinions are based off of comparisons between small VA and small, old IPS (irrelevant e-IPS if I remember correctly) panels. All LCD's suffer from white glow/contrast loss when viewed from less than a certain distance which varies. The GW2450HM is not a good monitor either since is uses PWM, a grainy matte coating, has slow pixel response times and has a small colour space/low sRGB colour space coverage. It would be one thing if you kept ranting about a decent VA panel like the BenQ EW2740L, but this isn't case.

You only see a little bit of glow if you have a complete dark picture but if i put a camera in front of it, then it will look ALOT worse then it actually is.
If i play a dark movie or a dark game then i see any glow yes gamma shift but NO Glow at all even if the movie has black bars at the top and bottom of the screen.

EDIT:
And does the EW2740L not have the same panel as the GW2760HS? because my experience i had with the GW2760HS was not good and i'm not alone:

Would a 50" have a significant difference in PPI from a 48"? There seems to be more TV's @ 50".

I am currently using a 27" 1080p which would be around the same PPI as a 55", however 55" is too big for my desk or else I would probably go for since it has more options than 50 (OLED, etc).

If you want to spend a lot on a TV and have space for over 50" then definitely go with an OLED.

55 could fit on the desk if the stand is in the middle, though the edges of the tv would be protruding a bit.

Is OLED noticeably better picture quality besides the deeper blacks? I just checked out a 48" samsung curved panel and a 49" IPS and was more impressed by the samsung, though to be honest when looking closely at both of them they both seemed blurry and maybe not something that I would want to sit 3 feet away from for long periods of time.

I did also look at some 55 inches and it seems like 48-50 would be more comfortable for a desktop since 55 would require head turning, also the curve looked really amazing from a couple feet away on the 48, the only thing about it is that I would not be able to re-purpose a curved monitor as a TV down the road since curve is not really good for sitting far away IMO.
 
OLED is better in everything and not only in deeper blacks once you go OLED you will never come back to LCD. But with every TV/Monitor you should make sure that the input lag is not higher then 30ms.

And if you want to know what the best viewing distance for you is on a 4K 50"-55" Display then simply multiply your comfortable sitting/reading distance of your 27"/1080p Monitor by 2.

Just checked out an OLED which looks the best by far, though 55" is too big for comfort IMO. I found curved 48" to be optimal for under 3 feet.

The only thing is that the only curves at 48 are from samsung which have PWM, can motion blur be turned off completely on these tvs?
 
PWM can be probably turned off if you set the TV brightness at 100%. But i think if you pay so much for a TV then PWM is a no go.
