    Hi Derek.
    Thank you so much for your review. May I ask you a question?
    Why if this screen is IPS, it is not mentioned on toshiba site?
    I even called them and they say it’s not IPS.
    I was about to buy this laptop from MS site, but was not sure about the screen.

    Thank you.

      The data sheet for the model of screen I listed in the review only says TFT LCD. That’s a very vague spec since a-Si TFT can mean either TN or IPS. I put IPS in the review because it looks like IPS to me, the color gamut measurements support IPS/PLS standards and I saw the panel for sale somewhere and they claimed it was IPS. It very well might be a different form of panel but it definitely wasn’t TN. If it was TN, it was by far the best TN panel on the planet because the color accuracy and viewing angles were really good.

        Hi Derek.
        Again thank you so much for that quick reply!
        Your help is so much appreciated. I kinda become obsessed with this, lol.
        In the article you said the Panel number is LGD0470 LP156WF6-SPA1
        I googled it and found this: where it says it’s AH-IPS.
        How did you find Panel number?

        Ah yes, there it is. I thought I saw it somewhere official but wasn’t positive. HWinfo gives you most, if not all of the model numbers of the components.

        Hi Derek.

        Thank you for the reply.
        So I ordered the laptop and got it yesterday. The panel indeed is LP156WF6-SPA1 and while looking at it at different angles it looks like IPS.
        I have no idea why Toshiba’s hiding this fact.

        Thanks again.

        It is IPS. You can use this test to determine the type of panel you have if it isn’t stated.
