    I stand corrected. Yes, its 16 ms. Been a long time since i remembered that number since most panels are usually lower in ms these days.

    And because of this, I'm thinking TN panels might not actually be so bad, given their typical response times closer to 2-5ms! We'd just have to put up with reduced viewing angles and color inaccuracies - which for me can't be that bad, because I'm colorblind anyway!

    Except all those numbers are fairly meaningless. Any screen that claims 2ms for instance is using its very best case. The problem is these numbers are different for every single color to every other color and there are very poor standards for how you choose which number to mention.

    This is an unrelated example of what the problem with those refresh times is:
    Lets say we have a game benchmarked on 4 computers all running the same game with the same GPU CPU etc... and they all get roughly this benchmark
    [​IMG]
    Laptop #1 reports its FPS as 104
    Laptop #2 reports its FPS as 58
    Laptop #3 reports its FPS as 28
    Laptop #4 reports its FPS as 40
    They are all technically true, but since they only gave 1 number with no other information it is still almost completely meaningless.

    Unfortunately this is the exact problem with the screen refresh numbers they all use different numbers, some minimum, some from a specific color to another and back like black to white to black(BtB) or gray to white to gray (GtG : also which gray?) but even then all the other colors may have differing times.

    So 25ms is fairly poor, but your 2ms TN screen may take 60ms for a certain color, and 6ms average no-one knows.

    Edit: Ah here is a good image of GtG response time variation on a display
    [​IMG]
    as you can see it actually varies from a low of ~2ms to a high of ~14ms

    that one is still not low enough, my samsung LTN156HL01-102 PLS panel gets 16ms resp time, try get that if you can

    I suppose I should start watermarking my benchmark results. :p

    In any case that response time graph is awesome, and wish every screen was required to provide such a graph. But even 2ms to 14ms I'll take that over anything that is 25ms. Panelook shows Typical response time which more or less means average. Sure there could be a flyer here or there, but a panel with 8ms average response time means the weight is distributed on the lower (faster) end to get to that 8ms. You can't have 50% at 30ms and still have an average 8ms response time. Your range is likely between 2ms and 16ms for over 90% of the color spectrum to achieve that 8ms average response time.

    I agree that a single number response time doesn't always mean squat, but higher numbers typically result in worse refresh and ghosting anomalies. But as it stands though this TN panel is a bit annoying with the super narrow viewing angles, I would probably take a 25ms IPS over this just because personally I use my laptop for 80% business/personal/browsing and 20% gaming. If there is positive feedback from users on this panel, personally I'd upgrade to that LCD. I'm strongly considering this laptop, but the LCD would have to change.

    This is true, but speaking generally, a TN screen will have better response times than an IPS screen. For someone who is colorblind and always sitting directly in front of the screen anyway, the narrower field of view and color problems might not be enough to push me away from the gaming advantages of a lower response time in the included TN toward the better picture of an IPS.

    In other words, I don't need to freak out and find another $100 to rush to get a replacement screen :)

    Well, crap. Maybe I do :(

    Yeah, this screen is "acceptable" and not like it's overly horrific, just I realize the brightness if nothing else is not that great. I'd take a higher quality TN panel (better viewing angles, higher brightness and contrast) even over an IPS for gaming.

    You are absolutely right almost all TN screens are better than almost all IPS screens, in response times. Just tired of people throwing outnumbers like 2ms as though it meant something. And I am pretty certain Panellook grabs its information from the manufacturer data-sheets, which my use different methods.

    Either way yes 25ms is rather poor.

    On the max hz mentioned, remember these numbers are combined Black to White to Black (BtB) or gray (GtG) so they are actually 2 transitions whereas hz measurements are only a single transition.

    And on the TN viewing angles, I am fine with a good one probably. My present one has awful vertical viewing angles though and I do not want to end up with that again. (Vertical viewing angle is bad enough on mine either the top gets color inversion, or the bottom is badly washed out no matter what angle you view it from. Ooh I just tested it a different way I can get perfect viewing at a specific angle if I sit over 6 feet away from the screen :err: )

    Would you say it's about on par with the p150sm-a?
