    Man, this thread moves fast - was busy for a couple of days - came back to find that I'm about 30 pages behind ;-)

    In any case, my findings so far:

    * Back-light flicker - yep, on gray background it's clearly visible and super-annoying. However, after digging deeper I've noticed that when running on battery it is more pronounced and when switching from the gray background to lighter one (like a browser with this thread, for example) it's visibly gaining-up the back-light and it takes a couple of seconds to stabilize. Obviously some power optimization thing. So, I dug through settings and finally found a check-box in Intel HD Graphics Control Panel under power settings to disable something called "Display Power Saving Technology" and this has definitely improved the flickering. I guess the driver attempted to scale down back-light intensity on darker screens to save battery and in combination with already poor back-light on TPY it produced poor results, to say the least. Bottom line - the flicker is still there, but less annoying, although the battery life will likely to suffer.

    * Ghosting - yep - got this too. I use a Win8 app called "Color Code" - it can show you a solid color full screen as a background and I use it with gray background swiping from the left between it and desktop to see the changes. I've noticed that the start menu button and a shadow of the taskbar remain visible when switching to the app. I need to try and leave it there for a while to see if/when it'll go away but it's definitely not a matter of seconds. I get the same results running on outlet and battery power, so it doesn't look like a power optimization thing to me. Also I have the same LEN40E4\LP125WF2-SPB1 panel as others, so I doubt replacing it will help...

    * Uniformity - when checking other stuff with Color Code on gray background I've noticed that the uniformity of the panel is also rather bad - I can clearly see uneven "blobs" and streaks. Not a problem for Visual Studio, but for Photoshop work I'd have to stick to my desktop monitors...

    * Lift & lock keyboard - have you noticed that keys around the trackpoint (G, H, B) are "less locked" than the others? They can be pressed while locked, although much less than in "normal" mode, while other keys right next to them (like V, for example) are rock-solid and not moving at all... I've read/heard somewhere that the keys are locked with a system of internal cables - perhaps it's a tension thing...

    Sounds like the display is towards the inexpensive line, and this was purposely chosen by Lenovo as they said in their youtube interview.

    + pluses
    ips / view angle
    bright screen
    1080 resolution
    requires matte film
    touch screen / digitizer option

    - minuses
    back-light flicker
    ghosting
    bad uniformity
    average colorspace


    I'd rather pay another couple hundred more for a better quality screen without the minuses. The new HP Zbook 14 has what seems like a perfect screen except for no touch and no digitizer

    The change of Fn and Ctrl is not the solution. I would like to use the keys F1 - F12 directly and not with the key combination Fn+Fx. I could not find such an option in the bios

    Thanks for your explanations regarding HDMI and VGA.

    Regards

    Ah, I bet this is what I am seeing when I notice a kind of shadow that stays in one place on white backgrounds when I'm scrolling webpages. I had posted a while back to ask if anyone else had uneven backlighting on their systems.

    Not a huge deal to me, but it is kind of annoying when you pay this much for a computer.

    If this is normal for the Thinkpad Yoga, I guess I'll just live with it since a replacement would probably be the same (or possibly worse.)

    You can press Fn + Esc to exchange the primary and secondary functions on the function keys. But as far as I know it doesn't last through a reboot

    I have been researching the TPY for quite some time now. I know pretty much everything there is to know about it at this point as far as the different configurations are concerned and the various accessories, or at least as much as it is possible for one to know, considering there is so much contradictory information out there, different Lenovo reps will tell you different things, many retailers will post incorrect technical specs on their sites, and a very limited number of retailers actually offer configurations of Lenovo products that Lenovo itself does not offer (not because they are discontinued models, but because they are paired with newer components, and Lenovo reps will claim such configurations do not exist). For example, the Yoga 11s is only available with a 3rd gen processor from Lenovo, no matter how much you are willing to pay, but Best Buy sells the device with the same configuration as Lenovo's 4GB/128GBSSD model, but with a 4th generation i5-4210Y processor, and for $100 less. Sorry for getting sidetracked there, just wanted to demonstrate that I've done my research, and as far as the dock is concerned, you can rely on my answer as gospel. The docks: The ThinkPad OneLink Dock is technically only designed for compatibility with the ThinkPad E431 and E531. It may work with the ThinkPad Yoga, but any glitches one may experience result from the fact that it is not truly classified as a compatible device. The ThinkPad OneLink Dock Pro (or 2 Pro as is it sometimes called) is designed to be compatible with a much larger variety of ThinkPads, including the Yoga. If you would like to verify this fact, simply refer to the following links: ThinkPad OneLink Dock - Overview and Service Parts & ThinkPad OneLink Pro Dock - Overview and Service Parts As far as availability is concerned, it is not the the Pro dock has not been released yet, it is simply sold out and on back-order, so there is a wait if one wants to purchase it.

    I am trying to decide between the FHD anti-glare with digitizer and the FHD anti-smudge without digitizer. After extensive bargain hunting, I have been able to find the two for about the same price, so that is not an issue. However, the digitizer is more of a bonus for me than an essential accessory (or so I think, having never used a digitizer I do not know how much I will appreciate its functionality). What does concern me is the anti-smudge factor. I have fingers that are a little more than average in the oily department and tend to smudge screens easily. Does the anti-glare screen feature anti-smudge with the added benefit of anti-glare? Or, does the anti-glare screen smudge more easily? I also prefer looking at an anti-glare display, as I work outside and in rooms with windows that allow for a decent amount of sunlight, so anti-glare seems like a good choice. However, I really do not want to have to be cleaning the thing all the time and I figure I could get an anti-glare screen protector for the anti-smudge model if the glare is a real problem. Lastly, is there any difference in touch screen sensitivity and accuracy between the two when it comes to using finger actuated touch control? This is also sort of important to me because, again, I really do not know if I wil end up using the digitizer all that much. I do not do graphic design, Photoshop, or anything like that, and I would never use it for handwriting, because mine is terrible and I write slowly any type quickly. However, I do use Excel a great deal and do a lot of highlighting, copying, cutting, and pasting from websites and in Word documents. I understand the pens are pretty useful for those functions compared to fingers on a touch screen. Is that the case? I'm open to any thought on these various concerns, but the anti-smudge vs anti-glare is the biggest issue. Thanks.

    Sorry I misread what you meant. I don't know if you are aware, but Fn + Esc acts as a Function Key lock. The Fn button lights up and the Function keys will work without holding the Fn key. I can confirm that on my TPY, it will stay lock even after a reboot.

    I have not seen the anti-smudge display, but the anti-glade display works quite well to stave off the finger prints. It wipes off easily. The anti-glare also works well to stop the reflection from the glossy screen that is underneath. I have to mention I removed the anti-glare coat after I scratched it with the digitizer pen (I'm still wondering how it happened, but it did). The scratch left a mark that distorted the color where the scratch was. Very noticeable and annoying. With the coating remove the IPS display is a fingerprint magnet. It did however make the screen appear more bright and vibrant. After I removed the coating, the nasty distortion was finally gone. I was contemplating returning, but I'm glad I didn't.

    If you can get them for about the same price, I'd get the model with the digitizer. It is handy.

    There are actually some slight differences between the two models. The one with the digitizer comes with the Intel 7260 AC wireless option, but has a 128GB SSD, and while the price is within $5 of the other one, the other one comes with a 256GB SSD, but the standard 802.11 b/n/g wireless option. I do not know if it is single or dual band, or if it is Intel or Lenovo's. The website does not say (it is being sold by B&H); it only reads: Wireless: 802.11 b/n/g. However, if I buy from B&H, I do not pay tax, as I have a friend who is a professional photographer who has a business account there and can make the purchase for me, so there is some difference in cost. However, I am really not concerned with the difference in hard drive size. I have 5TB of data on external drives and an extra TB of free space available on one of them. My real concern, in terms of tradeoff between the pen model and the other one (besides the screen) is the wireless option. I have read reviews by customers who have returned Yoga 11s models, and I believe also Yoga 2 Pros, because they were having trouble with the Lenovo wireless connectivity. Some reviewers said they were unable to establish or maintain anything close to an acceptable connection (for a standard user, I am assuming), without direct line of sight to the wireless router. As I intend to use the device in public settings, such as libraries and coffee shops, it is critical that I have good wireless connectivity. I regularly browse the internet with between 50 and 75 tabs open simultaneously and my task manager registers Firefox as using around 2GB of RAM on average. I think fast, read fast, and process information fast, so, because I go through so many web pages per any given period of time, I cannot afford dropped connections or slow loading. My productivity in what I do is based upon my ability to digest huge amounts of information quickly. I don't know if I am being paranoid or not about the difference in wireless connectivity, since I really don't know all that much about that technology, or, if it is possible to upgrade the wireless configuration after purchase or if it is soldered in place or something like that. Opinion on this matter would also be greatly appreciated, as I am trying to decide on which to purchase in the next day or two at the most. Regarding the anti-glare coating, I ama bit confused by your response. I was under the impression that the anti-glare coating was part of what enabled digitizer pen functionality, as there are no configurations available that offer the pen without the anti-glare coating. Does the pen still retain all of its functionality on your computer after having removed the anti-glare coating? If so, would it be theoretically possible to purchase the model with the anti-smudge screen, the 256GB SSD, the unknown wireless device, save on the taxes, accept the downside of glare, purchase the pen separately and still have the pen work? I am just curious to know all my options, as this will be my primary computer and I do not intend to purchase another one for quite some time. Incidentally, I thank you for your time and attention in responding to my inquiry and the promptness of your reply.

    Am I missing something here? Arn't the anti-glare/anti-smudge screens the exact same thing?
