Yoga 2 Pro Release Thread

I am not someone who needs professional color calibration, but an almost puke green for yellow that might be panel related is really turning me off...Things like office highlighter, that I planned on using a lot with this will probably always bother me a little, it not a lot. Also, viewing pictures are affected... I know video's are affected because the default yoga screen saver shows the yoga and in one of the pictures it shows the power plug in which is bright yellow physically, but on the screen saver video it is almost brown. It is a lot of money to spend on a screen that might bother someone to no end while doing almost anything that requires a yellow to be at least yellow and brown or puke green. I am also seeing a discrepancy in other colors as well, albeit less significant. I really want to like this device, hell I have bought 2 of them, one from best buy and one on order from lenovo direct. I hope there will be a fix but from my tweaking attempts nothing has come close to being acceptable. Maybe someone with professional knowledge about this will post some type of solution or let us know if it is not a fixable problem. At least then I can start the return process on both..... I still have my fingers crossed tho

 

I feel the same way. Not a deal breaker for me, but I could see how it would be for some.

 

I was thinking the same exact thing... Pentile displays on various phones are known for not properly rendering certain colors. I have a feeling that very little will be able to be done about it if this is the case.

 

When comparing the yoga 2 pro's colors and the colors on my t60, it seems that all the colors are a tad darker... then what they should be thus each color looks sharper but at the same time dirtier...

 

Pulled out my USB microscope and had a look at the Y2P's display.

First image is all white.

Second image is the intersection of white on the top and full yellow on the bottom.

 

fyi a 24/7 live chat tech told me this morning the ram is not soldered and there's 1 msata hd slot.

 

Ah! So this panel is using the Checkered RG-BW layout ( Subpixel rendering - Wikipedia, the free encyclopedia). As previously mentioned in a previous post by someone, the spacing between each red+green combined subpixel could be contributing to the "dullness" of the color. There are 2 "off/black" subpixels between each R+G subpixel combo (horizontally).

Thanks for posting these extreme close-up shots!

Also - EVERY Y2P will have this issue. Exchanging in hopes of getting one with less of an issue seems futile.

 

Not super familiar with display hardware. Seems odd that the white pixel would be off when displaying yellow. If that were even half way on, I feel like it would fix things. Gives me hope that a driver patch might be able to address this.

 

holy cow! that's unbelievable!

i don't understand this at all.. it's not like Lenovo guys couldn't see this during testing.

and if it's truly an issue with the Samsung panel itself and the AB9+ uses the same panel, then you now have both of the QHD+ machines on the market with major flaws.

 

That's what I was thinking.

 

It makes sense that they could do something, especially since the AB9 has the same panel and displays better.

 

no one knows for sure, but apparently it's the hardware/panel. if you need accurate color rendering, this is definitely not the model for you (yet).

hopefully there will be a mass amount of returns of the yoga specifying this reason so it can catch Lenovo's and Samsung's attention.

i was really wanting to consider the yoga for purchase, but this is a deal breaker for me in the current state since i use yellow in Excel and Word all the time. in addition, accurate colors should be a given on a product whose display is one of its top selling points.

 

Hopefully they can push out a firmware update that at least makes the yellow comparable to the AB9....

 

For those looking for a comparison and missed it earlier, here it is, and it is bad. How can Lenovo even call that ms paint color yellow...are you kidding me?!?! Really Lenovo???

 

hopefully some of you owners here will contact lenovo and make them aware of this issue, especially if you're going to be returning it for this reason.

their customer service and tech support are both pretty solid and maybe you could send them image files like the ones you've posted here.

so you believe the lack of density makes this an unfixable? nothing SW or FW could even improve?

 

I have posted my above thread over on Lenovo's support forums so hopefully we can get an answer on whether a fix is possible or not.

 

If you add white you get a less saturated yellow. If you don't add white, you get a darker yellow. This is the same for every color, but I think humans perceive dark yellow differently than other colors.

 

I would guess that a plugged in AB9+ Is using a brighter backlight and turning down the brightness of the white subpixels to get better color.

 

I work with photoshop sometimes, and this could become a problem for me. I love the yoga 2 pro, because for me it is the perfect ultrabook (besides the color issue). I'm not sure what alternative laptop to go for if this doesn't work out for me. I've been patiently waiting for the yoga 2 pro since June. I'm hoping there is going to be a solution from Lenovo once they are more aware.

 

Now we know why it's only $1199. Good thing about BB is they take these back without a hassle as long as you do it in whatever timeframe you have.

BTW, anybody else having problems with bluetooth losing connectivity for short periods of time?

 

we must mass report that issue to their support, maybe at the worst case, if it is indeed an HW problem, they'll do something about the manufactoring of the next units while replacing the defective ones.

 

See my photos a few posts back. They are actual photos of the Y2P's screen and are in a different configuration than these photos that people keep quoting.

 

Here's a bit that touches on the RBGW display. From reading this, and from others' earlier suggestions, it's probably a luminescence issue. That is, the yellow looks dingy because the back light is turned down too low for yellow, AND green might be too bright *relative* to red. All this probably to save power.

That was not the case with the AB9+ that I had..tried it all and it does not work.

 

I had to see this for myself and just returned from my local Best Buy. Even though I am not a graphic designer, the overall poor color display - especially the yellow (dirty green really) would drive me crazy. It's worse than I thought it would be and is definitely a deal killer for me. I was completely prepared to buy it today but now I'm back on the sidelines trying to figure out my next move. Ugh.

 

Just out of curiosity, are the display issues being had with both the i5 and i7 versions? While it shouldn't make a difference technically, just wanted to confirm if this was the case. It will also be interesting to see if these issues are only present in the Best Buy versions vs the ones that ship directly from Lenovo - perhaps they are fixing the issue hence the delayed ship date of next week?

 

Delayed ship of next week only has to do with the fact that lenovo directly is going to sell a lot more of these than best buy will.
So I'm sure they are swamped with orders.
I doubt the shipping dates have anything to do with this. And such it is such a glaring-in-your-face issue, I can't imagine they didn't see this which leads to they probably think the color is acceptable. If it's the panel imagine the cost to completely change out every panel for a different one after all the touting of super high res they have been doing. I am afraid that the only thing that can fix this is mass returns to lenovo to the point they have to do it.

 

I am also now actively participating in your thread...

 

Thanks dustindw... I saw your excellent post. Hopefully we can keep the pressure on Lenovo but I have a feeling this is not going to turn out good for us yoga fans.

 

I tried to buy the i7 at best buy today, but even though their system showed 2 in stock they didn't have any (they've updated it to be zero now). Regardless, I'm concerned about the color issue. I will probably still get one since the price and yoga functionality are still attractive to me. I'll return it under warranty in a couple months if it isn't resolved.

Anyway, maybe we should keep a list of model or serial numbers going so we can identify if it's limited to a particular generation.

 

hopefully that's closer to the real issue instead of these simply having bad panels. even then, however, it'll take some willingness from Lenovo to look and test this.

 

did your local BB have a Y2P on display that you looked at? or did you buy one and then immediately return it?

 

I recreated the subpixel layout of these displays in Photoshop using one pixel per subpixel. You can see that RGBW is brighter when displaying white, but darker when displaying yellow.

 

great job getting things started on Lenovo guys, hopefully they pay attention.. keep the pressure on! :thumbsup:

 

Samsung's Note 10.1 has a similar subpixel layout, and it didn't seem to have the same problems so hopefully this is something that can be fixed with an update.

Can you or did you post a link to your thread?

 

This display has fewer overall subpixels than a 13" Retina MacBook Pro :-\

 

is the wirless card user accessible so it can be swapped out for the 7260-AC card?

 

Here you go: Yoga 2 Pro 13 Yellow Color Issues - Lenovo Community

 

What is so much better about this card?

 

Can anyone who has one please post some CPU-Z information screenshots as well as some benchmark scores? I'm about the memory configuration - is it single or dual (put that to rest) and if it's single, how does that affect performance?

 

Great, thanks. I will watch this thread for a few days and if they don't respond (which I fully expect they won't) then I will stand in line with everyone else at BB to return the one I have.

 

Not sure if ekephart on the Lenovo community is from here or not, but that user made a comment on that forum stating "It's also worth noting, that allegedly the AB9+ and Y2P have the same display panel, but the AB9+ has a richer yellow." I must re-iterate that this is NOT the case. The AB9+ yellow looked exactly like the pictures shown here - the AB9+ display of yellow is "puke green" and nothing short of terrible.

 

Here you go. Thank goodness CPU-Z doesn't use yellow

 

NICE! Looks like dual channel is in the mix. Very good news.

 

Makes me wonder if this is going to be a problem with all the high-density pixel displays at this time. As a photographer, videographer and web developer, I can live with a little color inaccuracy on a laptop, but that's just *way* too far off.

Has anyone heard whether the high-density IGZO screens used by Fujitsu (and maybe on the Asus UX302?) suffer from the same issue?

 

it's AC dual-band running on 5 GHz instead of the N which is only 2.4 GHz. it's also got extended channel bonding, just much faster in general and best for crowded settings. also improves battery life. the Y2P was supposed to have the option of upgrading to this card, maybe Lenovo direct will offer it in customization.

 

They had a display model setup. They did not have any inventory that I could purchase (not that I wanted to buy it at that point).

 

But you won't have a second antenna to hook it up to, right?
