Hello there, thanks a lot for these awesome detailed review. May I know if there’s any screen door effect on the Yoga 9 2-in-1 (2025)? I currently have a Omnibook Ultra Flip 14, it has a rather bad screen door effect. Its very visible on bright content like white or grey background. I’m wondering if this is the also the same issue for the Yoga 9 2-in-1? If so, how bad is it compare to the Omnibook? (I know this is hard to quantify). I had a Yoga Slim 7 Gen 10 (with touchscreen), it doesnt any of these screen door effect at all.

Hi,

Regarding the Lenovo Yoga 9i 2-in-1, there’s no screen door effect per se, at least not in the same way as the OmniBook. The OmniBook’s screen door effect is subtle but uniformly everywhere, whereas the Yoga 9i looks more like the screen is a little bit dirty here and there. That said, it’s only noticeable on white backgrounds, and we really had to look for it at a few inches away from the screen, so you might not even notice it in normal use. Hope that helps.

Hi there, both these laptops are contenders for a single device that covers home office use and multimedia consumption, replacing an ageing Samsung Tab S8 Ultra. Multimedia: Comparing the 2880 x 1800 OLED screens for both laptops, I would have assumed the Lenovo to come out on top because of the advertised peak brightness in HDR of 1100 nits and SDR 500 nits. The review suggests the recorded SDR/HDR brightness is much lower, but in HDR the Lenovo is still almost double the brightness of the HP Omnibook. Both laptops received a score of 8.7 though and I was wondering the reason for this, as it seems to be the key point separating these two laptops? For reference the ageing Samsung Tab S8 Ultra has an HDR peak brightness of 795 cd/m². Trackpad: How big a difference is having a haptic trackpad (HP Omnibook) over a mechanical one (Lenovo 9i)? The scores of 8.5 to 9 suggest there’s not that much of a difference? I have a glass screen protector on my old tablet currently and I was wondering whether a similar type of product would be recommended for a laptop? Would a third-party screen protector damage the glass screen, inhibit closing the lid or impact the touch/pen sensitivity in your view? Many thanks :)

Hi,

Thanks for your questions. In regards to the brightness score, the reason those two score similarly is that we don’t officially test HDR brightness. We primarily do it as a supplemental test when a manufacturer makes a bold claim (like 1,100 nits). It’ll likely become an official test in a future test bench as HDR becomes increasingly more important.

For the touchpad, the difference between a haptic and a mechanical touchpad has to do with usability. With mechanical touchpads, the buttons typically only work in the bottom half. Haptic touchpads let you click anywhere, making it easier to perform some actions like dragging and dropping over a long distance.

Regarding the screen protector, it depends on the screen and bezels. If the bezels are under the glass, there’s a higher chance that the screen protector will touch the keyboard when you close the lid. It probably won’t damage the screen, but you may see some marks on the screen protector itself. Screen protectors generally have little effect on touch and pen input sensitivity, but it’ll affect how the pen glides across the screen, especially on matte screen protectors that have a textured finish. Hope that helps!
