Yoga 2 Pro Release Thread

no, but i think i will try that now

 

thanks, keep us updated on any additional testing you might do. this is very helpful for potential buyers and anyone still in their return window.

 

I will, now off to see if i have a micro hdmi cable anywhere...

 

Does anyone here with a new Yoga 2 also have an iPad 3 or 4? (the retina iPads are among the most accurate to sRGB among consumer devices)
Can you compare the colors below?

 

The yellow is yellow on my monitor connected to my Yoga. I can also see a decent yellow on my monitor connected to my Yoga in Excel and MS Paint. It is only on the Yoga screen that MS Paint and Excel don't seem to have a true yellow in the color picker. The Yoga screen still displays decent yellow's though. It is really strange.

 

hmmm, that doesn't sound very encouraging then. knowing there's color differences on different displays despite coming from the same source, it's probably an issue with the panel. who makes this specific panel? hopefully not LG.

 

Bad news. Mine shows the same thing as Led Zappa. This is definitely a panel issue. And the yellow (to me at least) is not a decent yellow it is a horrible yellow. I would call it almost brownish. Does anyone know if this is a panel issue if there could even be a fix besides replacing it??

 

Are you saying that when you look at a picture with yellow in it in a browser the yellow looks bad, because that's not the case for me.

 

I have the same issue, the yellow looks like a light brown. Thinking about returning the laptop tomorrow ;p. I wonder how common this issue is.

 

The panel is SDC (samsung display corporation) 424A

 

Try this google "bright yellow" on your yoga and your desktop..... do it under web not images... and check those yellows out. I am seeing a huge difference between the two. the yoga looks like a greenish brownish yellow.....

 

current owners will need to find out who makes the panel and then have enough yoga owners chime in and compare findings. maybe there will be some owners with accurate colors. in that case, they may have a different brand panel. then you'll want to return yours and try getting one with that type of panel.

Lenovo may be playing the increasingly popular 'panel lottery' game, where they source out their panels to different manufacturers with highly variable results. it's all about cost cutting and even Apple does it. if you're familiar at all with the MBP Retina panel issues, you'll know what i'm talking about.

 

Have you guys played around with Windows' color management settings yet? That could be messing things up.

 

yes, i have tried RGB in control panel/color calibrate to no avail......

 

while searching for panel type, the yoga's panel, sdc424a is the exact same panel as the ATIV book 9+.... big surprise.....and you had the same issue and returned. This is not looking good for us. If it's the panel there won't be a fix for it. And since it was the same problem with the ATIV book from samsung, I am assuming it is just an inherent problem with this particular panel..... wow I'm really unhappy about this as my 4 yr old gateway fx shows bright yellow just fine like my 30" mon on my desktop...
even my acer aconia that is almost 3 years old shows true yellow.

 

I know IPS panels have no problem with yellow - I'm staring at two gorgeous NEC 24" professional screens right now.

I'm a bit miffed that Lenovo is saying all over the place that the Yoga 2 Pro has an IPS panel, which is a specific technology, while the screen used in the Samsung Book 9 Plus is very clearly advertised as being Super PLS, Samsung's similar but not identical technology to eIPS.

Seems rather disingenuous, like if a company in the 90's claimed their monitor came with a Trinitron tube, but in reality it was merely an aperture grille clone.

 

Regarding the Yoga 2 Pro's ability to display the color yellow - I wonder if it has something to do with the way the pixels on the display are arranged. From what I can tell, it looks like the panel is using a different pixel layout than say the LCD panel on a device like the HTC One X. I used my Canon HF100's ability to take macro photos to capture some closeup images of both the Yoga 2 Pro's attempt at displaying yellow (doing a Google search for "bright yellow") and my EVO 4G LTE's (HTC One X) attempt.

Take a look at how the pixels are arranged for the Y2P versus the HTC One X (and other traditional RGB Stripe layout that displays).

The first image in the album is the HTC One X, the second is the Y2P. Be sure to zoom in when viewing the images.

Thoughts?

 

Hard to tell from those photos - need more resolution - but it kinda looks like the Lenovo's pixels are in a checkerboard pattern instead of a grid.

 

Oh, here's something - according to a review of the Samsung on notebookcheck, the yellow gets weaker when the unit's on battery, but looks normal when plugged in. Have you checked that?

"The brightness and intensity of different colors, in particular those with a large yellow part, decrease when disconnected from the outlet and the picture looks a bit paler. This effect cannot be countered even over the various energy-saving and brightness settings (including the adaptive brightness control) in the graphics driver. In our opinion, this issue is not particularly adverse in routine use and barely noticed in most cases."

 

From the AB9+ forums...

Sent from a different Galaxy using Tapatalk 2.

 

The color yellow is washed out / tinged - and it's starting to show up more and more in this forum. Haven't seen it on the Y2P, but the AB9+ definitely had this problem. I tried adjusting color channels, power management, icc profiles - nothing helped.

 

I found out the linux wifi issue.

The 7260 is not supported until kernel 3.10/3.11. Someone got one working by compiling a custom kernel. I purchased this because the support rep for lenovo (on their official Q&A site) said that it would support Ubuntu.

Last night the support tech I called said, "you shouldn't install an operating system. We don't have windows 8 keys to give our customers for reinstall yet."

I have a new windows 8 key I could use, but they didn't even offer media to restore the system. Sadface. His recommendation was to exchange it.

 

That would be the IPS technology at work. An IPS panel displays pixels as chevrons. See Wikipedia for a decent picture.

Also, the driver updates via Windows Update seem to have fixed my WiFi issues, so install those updates!

 

So every Yoga Pro 2 will be affected by the off-color yellow, but I was wondering to what degree? The color selection for yellow in Paint is off, but for most people, when looking at yellow images such as the square posted in this thread or googling bright yellow - is the yellow a light brownish tint?

I am trying to determine if it is worthwhile exchanging my laptop or do I need to just return it if I can't live with the "yellow" color. I wouldn't mind a slightly washed out yellow, which it sounds like the Samsung Ativ Book Pro has.

 

No, that's something specific to S-IPS panels, not regular IPS or eIPS or Samsung's PLS as is the case with this screen. Besides, that's a grid of chevron shapes, not an alternating checkerboard of small squares like in the poster's photo. The two are very different.

Shame though about the yellow here - even the TN screen on the Sony Z11 I'm using at this moment shows yellows so bright and vibrant, they almost hurt your eyes...

 

Which one do you guys it is better in terms of battery? I5 or i7? Anyone tested two of these models?

 

I don't think the lack of a bright yellow is a deal-breaker for me, but it is a little disappointing. I feel bad for web developers/graphic artists who picked up one of these.

 

Ok here is what you will get:

This is coming directly from my yoga 2

This is ms paint yellow (Yoga)
View attachment 103346

This is win 8 background yellow (solid colors)
View attachment 103347

And this is what you will get from a normal desktop pc (taken directly from my 30" monitor)

This is ms paint yellow
View attachment 103348

This is win 7 background yellow (solid colors)
View attachment 103349

Absolutely Huge differences.

 

hah! Same here - had my old Sony Z11 and Pro 13 on my desk in comparison to the Samsung ATIV B9+ - absolutely no comparison in color accuracy. Great spatial resolution on the Samsung, but the it's like driving a Porsche that sounds like a Datsun. No way, no how.

 

Great example, this pretty much replicates my yoga 2 pro's yellow color issue. If anyone hasn't purchased it yet, I would suggest looking at this to decide if you're fine with this problem. It seems pretty widespread already.

 

Also, I used google search "bright yellow" (for those of you who want to see for yourselves) on my yoga, its looks horrible, like above. So I did a print screen of the google page, pasted to paint and sent the file to my desktop pc. Guess what, the file looks just like the yellow my desktop pc shows when in the browser doing a "bright yellow" search in google.
I also checked windows calibration on my desktop pc vs the yoga 2 and all 3 RGB were set identically.(default since I have not changed them on either device)
This means the yoga CAN get the color right when saving a print screen from a browser and sending it to another pc without this color issue. It CANNOT however display that same "correctness" on its own display...
This is troubling as I am sure this applies to more than just yellow, the panel is probably affecting all the colors, you just don't notice it as much on other colors as you do on yellow.

 

Well, the yellow smileys posted in every third post on this site seem close enough to me...

 

Yup, mine has the same yellow issue.

 

I have the Y2P and the AB9+ sitting next to each other on my desk along with a HP Pavilion DV7. The yellow on the AB9+ is definitely brighter than on the Y2P but both pale in comparison to the HP. The HP is what I would consider truly bright hurt your eyes yellow. The AB9+ is less bright with more green in it. The Y2P is the palest and even greener. Mine does not appear as pale though as some posted earlier. I'll try to get a picture of the 2 together and see if the differences are visible and post it.

 

Is this a hw problem with the panel, a color calibration issue or a software issue? I was just about to pull the trigger, but I need accurate color rendering for what I am going to use it for.

 

I just looked at the red in ms paint, on the yoga it looks like red with an orange tint to it. just slightly, but you can see it. On my desktop pc the same red looks....well red.. normal red

 

So the camera doesn't show the actual colors as well as I'd like, it does show the difference between the 3 machines.

The Y2P is on the left, AB9+ in the middle and HP on the right. The HP is really bright yellow in person. INTERESTING 2 PHOTOS ARE APPEARING UPSIDE DOWN _ WILL TRY AGAIN


The Y2P is on the left, AB9+ on right - in real life the Y2P is greener and paler


The Y2P is on right sitting on HP keyboard - HP is bright hurt your eyes yellow

 

I'm seeing the yellow problem as well. I'm guessing that it is a color calibration issue, though I'm certainly no expert in such things. I can't imagine there'd be a hardware problem with the display that would prevent it from showing yellows properly.

It isn't overly concerning to me, though I'd definitely like to see a fix from Lenovo.

 

Has anyone had a chance to see if this makes a difference with the Y2P? I didn't read this until this morning, and I didn't get a chance to try it out before I left for work.

This would sure be strange behavior! All of my "tests" and checks so far have been while on battery power though.

 

I'm plugged in at 100% and I'm seeing the odd yellows.

 

conformed...plugged in and weird yellows, but its not just the yellows, a lot of the colors are off on this panel.

Orange


Yellow


The red is off a little too, blue you cant tell as much and gray white and black can't tell.

 

How is the yellow highlight function in ms word on the Y2P for someone who has it?

I do a lot of highlighting word documents and it would be unfortunate if that looked terrible...

 

My observation with my Yoga 2 Pro is that their is screen management software that is changing the color presets depending on what you are looking at, e.g. movies, web surfing etc. I have a Dell 30" which does similar auto adjustments, i.e if I am on a black dominant page it adjusts the brightness vs. a page which is primarily white. I have noticed the Yoga 2 Pro doing the same thing. s
So I think this is some sort of color profiling that is at work behind the scenes.

 

I am not sure how this can't be a hardware problem. The display is a samsung 424A which is the same panel as the ATIV (also samsung) and previous poster said they had the same problem with the ATIV at same res and had to return it because of it. Also, when i send a screenshot of an internet page it looks bad on the yoga, but that same file looks great and accurate on my desktop pc..... I am having a hard time thinking this has anything to do with drivers or software. I not an expert, but someone who is please chime it on your thoughts based on available info so far.

 

I'm seeing the yellow issue, but unless I'm looking at a square of solid yellow, it's really not all that noticeable. I doubt I would have noticed it at all if not for this thread. Not a deal breaker for what I use the computer for. However, if you're a graphic designer or artist, this could be a major issue. I've messed around with Windows monitor calibration and even a third party color calibration program and that doesn't really help much at all. Hopefully there could be some driver patch or something, but not sure that's possible if it's 100% a hardware problem.

 

That is my concern too and yes, the yellow highlight looks brownish green, definitely not yellow. That yellow highlight in office was what started this whole thing about 10 pages back...

 

Even if it is profiling (even though I have looked at the profiles and there are non listed) wouldn't me changing the RGB and sat and hue allow for true yellow? Or would that profile your speaking of prevent it? I have messed with all the calibration from windows and can't get it close at all even after 30 minutes of adjusting.

 

I won't do professional color work with this monitor and will mostly be using it for writing, watching movies, and sometimes looking at pictures. I also have a desktop with a nice IPS monitor and that's where I edit my snapshots. If the yellow in MS Word highlights have a slightly different tint I don't think I'll care, and I've never used MS Paint in my life (and if I did I would do it on the desktop). Will I care about this color issue at all? When I watch a movie, which is often, will this be a big thing that will jump out and annoy me? I've been surprised by how many people are calling it a deal breaker when I assume that most folks aren't going to use it for professional photo work. Am I missing something? (note: I'm not trying to criticize those who are complaining and I appreciate their willingness to share what they've learned--I'm just trying to figure out if I'm wrong to assume that I will have a different tolerance level for this issue). Thanks for all the useful advice people are sharing.

 

I think I noticed this last night. When I viewed a very light webpage (such as these forums) after using a dark app, the display would adjust the the brightness over time (a couple nits, then another couple nits a second later). At first I thought there was a loose connection somewhere causing my display to go a little wacky with the brightness, but it stopped after a few seconds.

Monitors can have very different color profiles. How they display colors is typically consistent within the model, but inconsistent with other displays. Owners of my old laptop (Vaio F11) on here have a few different color profiles that they like, and its usually a subtle enough difference that it is simply a personal preference which one is "best." I think most of the profiles came from using special calibration equipment such as this. Of course, the color issues here are a bit more than simple preference, but it would be neat if someone happened to have a calibration system sitting around to try out.

 

From dustindw's pictures, it's clear to me that the panel is of some sort of pentile variant. There's that very distinctive checkerboard subpixel pattern:

These are typical pentile displays found in phones (Galaxy S3 and S4 shown here):



Pentile displays essentially have only 2 subpixels per pixel and have notoriously produced off-colors. It's easy to see why. To make yellow, for example, you need the red and green subpixels. But as shown above in the two phone pentile displays, you only have half the number of red subpixels as you would in a normal RGB matrix. The green overpowers the red and you end up with greenish yellows.

Whereas the phone examples use an RGBG layout where every pixel has a green subpixel + alternating red and blue subpixels, the Yoga 2 Pro's panel looks like it has alternating green and red subpixels (I can't tell what's going on with the blue subpixels). That means that at least the green and red subpixels aren't very dense (not close together). I think that would would explain the dull yellows and reds people are noticing.

If I'm right about this, then this is a hardware issue, and I don't really see how it can be fixed. I hope I'm wrong though because I'm looking to buy the Yoga Pro 2 myself.
