Samsung intros IPS competitor: PLS

Looks very much what backlight bleeding would look like, hopefully just a bad unit. Damn LED, that's what worries me the most about this monitor. Most recent LED backlit Samsung monitors have problems with backlight uniformity, don't they?
 
On the way to class I was thinking that the general room color appears to be reflected as the center blob, but the discoloration in the corner did seem to have the same value as a back-light bleed.

How do companies let that crap get by? There are layers of diffusers between the LCD and the LED. How much extra would it cost to make the diffuser always fit correctly?

It is not a reflection, the lower left looks identical on all the photos. That is backlight bleed. There is also some orangish glow effect going on on the left side and a blotch in the middle. If it's just minor glow and not some type of permanent dis colorization I could live with it. Thanks for the pics
 
Oh man...

The white background isn't white, they used some color fades as a background for their sheets. The black background is indeed 100% black, but the pictures made by Oled are 90 degree rotated, the bottom left is actually the top left, it is possible that it is just a reflection of the ceiling lights of the hall! It looks like that if you look at the original pictures and not the mockups by Oled.

And last but not least - when do you guys finally stop analyzing a panel or backlight by just a low quality photo made with completely random light conditions? Sure, we got a shitload of crappy displays over the last few years, but analyzing something with that little information is just stupid!
 
When we have something better to do! Or better source material.

There's a reflected glare on the bottom left bezel. It could correspond to the white light source reflected in the top left. On the other hand, the shadows indicate that the brightest sources are directly above. That would suggest that the bezel reflection is from the above (probably track lights) and that the anomaly in the corner is actually BLB.

Just one thing. I didnt posted those pics.

I pointed out the sick of manipulating photos for this kind of purpose.
 
Why is it even important to discuss whether the monitor in the picture has backlight bleed or not? If it had, be glad that there's no chance of this particular monitor becoming shipped to you.
Secondly, there's nothing to be said for certain until quite a few amount of people have got the new range of monitors and can report back.

However, it does look like back light bleed (not the blotch in the middle, which is just a reflection) and it is certainly is embarrassing that Samsung (or any other company for that matter) would use it as a demonstration unit.

Thats exactly the reason why discussing it is important. If they cant even get a demo/show unit right it doesn't look too good. This might just be an early prototype/engineering sample to show off the PLS technology or it might be a bigger problem. It might even cause Samsung to change their manufacturing process to correct the problem. If nothing else it might help people decide on this monitor or another.

I'm trying to decide on which monitors to use for an Eyefinity setup. So far its this one or the 30" HP.

I really hope people are not basing any sort of purchasing decisions on the few pictures that have come out of a demo unit at a trade show :rolleyes:

Hopefully not but its not available yet either way.
 
I think a lot of people have high hopes for this. OLED is distant at best as far as computer monitors and *VA technology died. I have a P-MVA monitor and it'd be nice to know what is capable of replacing it.
 
They still have VA like Samsung F2380. But of course notorious liars samsung is, their quoted "8ms" ghost more than non overdriven IPS's which quote 16ms...I wouldnt have my hope up this tech will be much of a replacement either given Samsungs history and delays.
 
That's because the 8ms comes from a gray to gray transition - which might in fact be a 8ms - but many of the other transistions are very slow. IPS monitors are more well balanced..
 
There doesn't appear to be any news about the monitor. I suspect the tsunami threw off a bunch of these early predictions.

The new Galaxy 10.1 tablet will have a PLS screen, and it's schedule for launch in early June. As far as I know, it will be the first time a PLS panel of any sort will be in the wild, so should give some insight into it's characteristics.

are you serious? where do you read it?
 
I haven't understood well what is the PROS and CONS of this PLS technology, is there something that clarify this?
 
There are no PLS products yet.
No one can clarify anything until the first monitor is released.

I'm starting to lose interest. LG likely has ultra high res LCD AH-IPS monitors in development, might be worth the wait.
 
Hmm I want to know if this monitor is going to have alot of input lag - so not sure if even good reviews on the panels in the tabs will help it. I totally wish they didn't add the scalar...

I hope so. I personally love IPS based monitors. The AG doesn't seem to bother me like it does others. I really wish that LG would find a way to make putting A-TW polarizers in their panels cost-effective and standard on ALL IPS monitors.

Well, according to flatpanelshd.com, LG only had the ultra hi-res 3840x2160 panels in their 55- and 84- inch HDTVs. Their 27" display at SID 2011 was still running a native resolution of 2560x1440. :-( The weird thing is that this promotional image does show a 27" display with 166ppi (3840x2160).
http://www.flatpanelshd.com/pictures/lgsid2011-1.jpg

No idea why they wouldn't demo this hi-res 27" at SID. Either way, I really hope Samsung has something comparative on the horizon with PLS. After my terrible experience with the DELL U3011, I'd happily go 1440p PLS over 2160p IPS.

Nice catch, I saw that the screen demoed was 1440p and wondered why the fuss about AH-IPS. 166ppi is a lot more interesting.

other IPS related annoyances aside, 3840 x 2160 is a great resolution to do everything:
Excellent workspace and clarity, 1080p will map pixels 4:1, 720p will map pixels 9:1, and there should be no need for laggy scalers. The icing on the cake would be true 120Hz refresh (not that I really expect it to happen)
 
You guys do realize that not a single website or application is able to just "double the graphics" while remaining a decent image quality like they did on the iPhone? The whole internet will look like shit with double-size scaled graphics for years. I even doubt that we will ever see a 100% "retina display" optimized internet.

IMO retina stuff is for portable devices only, micro-sized websites isn't an issue on a smartphone.

I use firefox and dial up the scale factor on my 30"rs, looks good to me.
 
You don't scale any graphics on today's displays. 30" with 2560x1600 have a DPI of 1xx or something. High res displays offer a higher resolution at the same size, meaning all graphics have to have a higher resolution.

Conclusion

The Samsung SyncMaster SA850 with its Super PLS matrix is not an ideal monitor, but it’s good.

Samsung has indeed begun to manufacture LCD matrixes which are similar to IPS and capable of competing with e-IPS in price and beating them in specs, especially in terms of viewing angles. PLS matrixes do not have the annoying effect of e-IPS ones which show a brighter black when viewed from a side. Considering the comparable price, PLS makes a more appealing option.

On the other hand, it is yet too early to talk about any competition with e-IPS on the market of desktop monitors. PLS is only going to be available in a single product so far. And while the 27-inch SA850 (S27A850) is interesting due to its high resolution, it can hardly challenge mainstream 21.5- and 23-inch e-IPS based monitors.

It should also be noted that Samsung becomes the only company to produce LCD matrixes of all possible types: TN, VA (C-PVA for the SyncMaster F2380 and S-PVA for TV-sets and large info boards), and now PLS which is functionally similar to IPS technology. This may be due to the company’s ongoing search for the most promising and demanded solutions. Instead of making its decisions in labs and at internal meetings, the company releases products with all technologies available to it in order to check out the reaction of real users. This approach brings about more choices but, on the other hand, the buyer may easily get confused.

As for the SyncMaster SA850, this particular product seems quite competitive to me.

Highs:

Serious exterior design, good functionality and handy controls
High native resolution
Low response time, good color rendering, excellent viewing angles
Full coverage of the sRGB color space
Matte coating of the screen that is free from glares and graininess
Three digital inputs and a USB 3.0 hub
Ambient lighting sensor

Lows

Low contrast ratio
Poor uniformity of backlight for black

Even now, three months prior to its official release, this model has more highs than lows. If the manufacturer gets rid of the backlight irregularities, the SyncMaster SA850 will easily become one of the best products in its class and an indispensible solution for people who need a high resolution and good color rendering but cannot afford a 30-inch monitor. The SA850 will also be good as a versatile home monitor.

I hope that PLS matrixes will go beyond 27-inch monitors and into 23-inch and 24-inch products at prices comparable to those of the same-size e-IPS models. After all, if PLS is planned for such different devices as 10-inch tablet PCs and 27-inch desktop monitors, there must be no technical problems with producing a 23-inch PLS matrix. I’m now waiting for Samsung to release one!

Semi Glare Coating ! :D
The End of IPS
the principal question is when it enter into the shops !
 
july ?
yes for 27" version but when july ? it is formed by 31 days, and in july there is the lauching but when will be in the shops ? july can means 31 july, then August is close, then september ?

and 24" version ?
Samsung is too slow
 
2560x1440? It seems to be missing 160 vertical pixels. Bring back 4:3 for 2560x1920!
 
Hopefully the fact that it's 1920x1080 instead of 1920x1200 will reduce costs.
