4K screen - poor viewing angles.

I've just bought an AOC 27" 4K screen, primarily for business use, but it will likely get used as a second screen for editing too. I've had one 4K panel previously, a VA model from Samsung, and the falloff was terrible, quite unusable, but this one is IPS and advertised as having great viewing angles. As it is, sat at around 18"-24" as I would be with my QHD screen, the sides are really dark compared to the middle. Is this normal with a 4K screen, or do I just have a crappy one?
 
Would you care to say which model number you have?

Also, IMO you are sitting a little close......though that should not compromise the viewing angle question of an IPS screen.

You say it falls away if sitting facing it square on, what about if you turn it and move position to 'view' from a more acute angle.

Oh, is it set at factory defaults i e. nothing changed in it's setup including viewing it's default 100% resolution and not at say 150% to see text more clearly on such a high resolution screen.

PS I am still on 2K so the is just address what comes to mind.
 
U27B3A is the model. I'm doing a direct comparison with the Gigabyte M27Q sat beside it, which is a 2560*1440 monitor, and there's no fall off on that screen.

Windows automatically adjusted to 150%, and I reset that to 125% because I want a large virtual workspace. Changing scale made no difference.
 
It’s panel dependent, types of panel tech and coating. Not 4k or HD.

It a lot to do with how it is lit, edge lit, zones, how many zones?

If I were to get a new monitor these days, I would get and OLED.

I just don't want to spend £350+ on a work screen.
 
I'm afraid you get what you pay for on these, sounds like a light distribution issue. If you're looking at 4k with good colour reproduction you're probably £400+.

I have a pair of Dell u2723qe which I'm delighted with.
 
As above, looks like a pretty low end monitor.

Though think more like £600+ for "good" colour, i.e. professional colour work. Though the dell "ultrasharp" branded ones (As above) are an excellent balance of price/quality. I've certainly had very good quality 4k screens for critical image use for work, they were around 700 a screen mind.

The talk of zones above is unlikely to apply - there won't be any zoned backlighting/local dimming on a cheaper screen.

I incidentally got Samsung S8 IPS monitor in December which ended up being free due to defects and generally being s***. It's just collecting dust now... I got lucky here. It is really unusable with bad angles, gamut is nowhere near advertised, centre is much brighter than even mid section. Basically unusable

The relevant part is that viewing angle is.... Terrible. Looks like IPS technology got really downgraded over last few years. My friend told me his new Asus has the same issue. Shocking

Just buy oled now. Don't waste money on old crap

You have to keep 100% or this really kills image sharpness. How the f*** does Microsoft not understand this?!
 
OK, thanks gents, cheaping out wasn't helpful apparently.

Return it?

Most cheap screens just won’t cut it. If you want to go cheaper then go lower resolution, 1080p screen with a better panel over a 4k with a worse panel.

1080P simply isn't enough resolution. As I said, this is a work screen, and it's not unusual for me when using a monitor 1920:1200 at 100% to be using excel at 60% or 70%. My other monitor is 27" and 2560:1440, but for this work a little more resolution would have been nice. Also the choices at the cheaper end often had poor colour gamut (93-99% sRGB) where as this had 123% sRGB. I've never seen an IPS panel with such poor viewing angles before.

That's fairly likely. I'm reluctant to return items that aren't actually faulty, but this doesn't live up to the promise of viewing angles.

I guess you just have to pick your poison: cost, resolution or panel quality.

It's like buying a tripod, 2 of the 3.
 
I'll have a day working from home tomorrow, so I'll give it a proper test drive & decide.

If you don't, I think you'll always regret it.

Would be 100% what I do here. Return the trash & teach them a lesson to stop passing junk as the real thing. Even better if you can find some obvious fault like dead pixels. Unfortunately some sites will not take them bacj this easily and will even try to take off 20% for restocking. You have to be swift and very determined if you want this gone, maybe even invoke paypal / cc, etc.

why don't you just measure? My crap was supposed to be full P3. It barely fits srgb... and I've tried everything in OSD. Good job it was already refunded 100% at that point. It was the last time I had it on btw. It would work for spreadsheets or some stupid gaming but not much else.... Definitely not an IPS we used to know and like back in the old days.
 
A little late reporting, it's good for work purposes and image editing after calibration, using 125% scaling. There is a minor issue that, as I've seen before on high Res screens, images at 100% look better than they really are, but this was ok. Fall off when editing after calibration was much less noticeable than before, possibly I've got used to it, but all the same, it really wasn't an issue.

It was nice for work, having lots of documents open at the same time, all findable, easily read. The previous screen I used for work was 1920:1200 24", which was incredible 10 years ago, but now feels cramped - in my office here I use 2 side-by-side. The only obvious other flaw is that refresh is only 60hz, so moving a mouse pointer isn't smooth like on my 170hz screen, but again that doesn't affect work use.

I'm going to keep it, as for £160 it's really good value. If I wanted something superb then a £600 budget would be reasonable, but this is quite functional.
