    I've recently received my x200t with multitouch screen, and is a little disappointed by the display.

    I've found the extra touch layer really diffuse the screen, making it lose brightness very fast when viewed from the side. This and the fact that the diffused layer blurs the screen at greater viewing angles makes taking notes or reading by putting the tablet on a flat surface not very easy on the eyes.

    The screen grain is noticeable at high brightness, and the details are slightly blurry, all because of the diffused touch layer surface no doubt.

    My biggest problem is with the screen when viewing in portrait orientation. Because the screen brightness falloff is very sharp, this makes the brightness directly under each eyes uneven. This gives a "shimmering" look to the screen, making portrait reading very unpleasant.

    I'm considering returning this tablet and get one with the LED frameless screen. But I'm wondering if this is a common trait of the multiview screen in x200t, or is it something I can fix with a replaced part.

    Thanks

    It's not because of the touch layer, because there is no touch layer on the front in the first place ;)
    The touch layer is at the back of the screen, so if you get the frameless version, you will still have the same problem.
    Time for me to break the news for you. The screen that X200t uses is PVA, not IPS. As such, the viewing angle is worse. The PVA panel on my X200t is washed out after a certain angle.
    I would recommend that you get the X61t instead, with true IPS screen, or the CCFL variant of the X200t, which still uses the IPS screen.
    The graininess can't be fixed, however. This is seen in most tablets. Best to live with it.

    Really? There's a frameless version of the x200t at a reseller close to my work place, and the screen looked absolutely perfect. What is the CCFL variant?

    My main grip is with the impossibility of portrait viewing because of the uneven lighting seen in the screen. Everything else I can live with. I didn't see that problem with the demo frameless machine in that store.

    sorry zephir but your informations are wrong.

    The X200t is available in two models.
    A version without the passive digitizer and a version with the passive digitizer.

    The passive digitizer is in front of the display, behind the display is only the active Wacom digitizer. Any passive digitizer will worsen the display, reduce the brightness and add some grain to the display.

    The frameless version has a much better 'display' because it does not have the passive digitizer in front of the display.

    Still, as you said, Lenovo uses a PVA panel, which is, compared to the BoeHydis panel (probably AFFS+, because it is 300nits bright) used by Fujitsu worse in every way
    TN Film, MVA, PVA and IPS - Panel Technologies.

    I haven't seen a CCFL variant (uses a worse Cold Cathode Fluorescent Lamp instead of the much better LEDs as backlight) either. Maybe it's the cheapest display option, but why should this use an IPS display then?

    i actually thought the review on here might ahve been based on the CCFL variant because the blues did not seem to distort as much as those on the screenshots from jonlumpkin on his x200 with the LED backlit no touch version

    Have you ever seen the HP-TX2 pen/touch? I almost made the mistake of ordering this.

    Be glad with what you and I have! There's a LOT worse out there.

    Of course, this is just a subjective opinion, but I wouldn't say the non-touch display is "much" better, I'd say it was a little better. I finally got to do a side-by-side under real world conditions when I met a woman with the frameless version on a commuter train. It's true that the frameless display can get a bit brighter than the Multitouch and that it seems to have a little less grain. The viewing angles, font sharpness, and colors appeared identical. I think in most situations the brightness won't be an issue since keep my display considerably below max unless I'm in direct sunlight and it's not difficult to see even then (although if you're using your tablet in direct sunlight most of the time, you'd probably want all the nits you could get). Similarly, the little bit of grain isn't really noticeable (to me) while I'm working, maybe because of the changing light or maybe you learn to see through it. Neither one of us was using a screen protector and I was surprised at how unobtrusive the touch layer really is. I will the say the style of the frameless version is very cool and looks sleeker and more modern than the Multitouch - but I'm not the least bit tempted to give up the touch function.

    Yeah, I was wrong about that. Sorry for the misunderstanding. Still, according to somebody on the Lenovo forum, the CCFL variant of X200t uses IPS screen. I think you can search the forum on that.

    For the X200T, there was a change in what Multitouch refers to. At first it was pen + 1 finger, later it changed to represent two finger support. As the pen is always supported, it only stands for more than one (=2) finger.
