Quote from: TFLOP on August 20, 2025, 18:00:31I'm confused about the HDMI specs of this laptop (and many other Lenovo models). It states HDMI 2.1 but resolution up to 4K@60Hz. That's way lower than HDMI 2.1 spec. Is this somehow throttled down?

Also, there's no mention of the Thunderbolt 4 ports offering DisplayPort video output (and at which resolutions/refresh rates). Anyone got data on that?

Ok I did find more info now:

Monitor Support[1]
Supports up to 3 independent displays (native display and 2 external monitors via HDMI® and Thunderbolt™)
• HDMI® supports up to 4K@60Hz
• Thunderbolt™ supports up to 8K@60Hz[2]

Notes:
[1] Refresh rates >60hz also supported, however max resolution will be limited.
[2] 8K resolution support needs 2 display pipes. That is, simultaneous display number will "-1" when 8K resolution
displayed.

This review convinced me to buy this laptop.
I am disappointed that the fans are not usually off like this review states. They will spin up for no reason, the fan curve is overly aggressive.
Thankfully I am able to mitigate it with TPFanControl2.

Is the slight decrease in performance with respect to the 14-inch[1] mainly due to the differences in power fed to the CPU?

If so, any insights as to why Lenovo might be constraining power more on the larger device?

Put hx 370 or strix halo in something like lenovo z16 gen 3, then I might switch back from macbook. I can't even do anything with those f* intel e cores.

Quote from: Randy on February 25, 2025, 17:49:42Lunar Lake proves intel can match two year old Apple Silicon in battery life, at half the performance and with a robust fan to keep from melting.

It would be bad if a tablet processor that can't run many desktop applications doesn't get good battery life.

Aside from the horrible keyboard I'm tempted which is a bit concerning

How does the Haptic trackpad on the X9-15 compare to the Haptic trackpad on the X9-14?  I've read that the one on the X9-14 is much better than the one on the X9-15, but I'm not sure how or why. I'm hoping to hear comments from someone who has personally used both varieties of Haptic trackpad. Thank you.

Quote from: Joe on February 26, 2025, 11:51:23I cant looked at the screen for more the 5-10 minutes with out have eye pain that last hours. Now i do notice this X9 has 1200hz so now wondering why the screen was bothering my eyes? any help would be great as for it my favorite laptop ever.

1200 Hz is high enough, typical mobile screen has around 250 Hz only. There may be a diferent issue. The display resolution (density) is quite low for a 15" screen (I'd accept 4K at least) and OLED use different subpixel matrix than LCD screens that looks more unreadable in low resolutions. I've seen a 1920x1200 15" OLED that was absolutely awful, there were always red shadows next to white text on black background as a result of the low resolution and different subpixel matrix. I wasn't able to use it at all. 4K screen was ok, as the resolution is high enough to hide it.

Subpixel rendering should not be used on OLED screens because they are usually designed for LCD subpixels and may cause weird colored artifacts around text. It's nice that Windows allows you to configure the type and parameters of text rendering on each display separately.

My laptop has an 15.6" OLED screen where pixels are so dense that the type of rendering doesn't make much difference, though. Text is always extremely sharp so that you can physically approach the screen to read tiny text, e.g., in PDFs, instead of zooming in.

It is not just the track point that is missing... There is literally nothing left of what a Thinkpad is supposed to be:

Lousy keyboard ergonomics, tiny keystroke, half arrow keys...
Glossy screen full of reflections
Non upgradable internal components
And last but not least.. no trackpoint.

You can shove it up your @rse Lenovo

Ugly rebadged Ideapad.
Lenovo=Chinese junk.

Its not a thinkpad without a trackpoint.  They can call it whatever they want but its just not.  Its just using the brand name to sell a notebook.  Its bad enough they got rid of dual battery systems with hot swapping.

Quote from: davidm on February 25, 2025, 16:05:30otherwise the only thing better than a trackpoint would be eye or mind control.

I've heard rumors of a revolutionary new type of pointing device that is under development, and that is vastly superior to both trackpads and trackpoints. They call it a "mouse".

A mouse is not superior to a trackpad. It's probably the most primitive. Having to move a significant part of your body just to move a pointer, something people might do many times a minute, is absurd. Not to mention needing a desk layout and having to carry another thing. Of course, it depends what's being done. But for software dev, the trackpoint is best, even with a mostly keyboard driven workflow. I guess that notebookcheck's perspective is becoming gamerz, so I can't speak to that. I guess spending days running around in a dark tunnel with a schlong^wweapon in front of you, a mouse would be better.

Great Review, So on the topic of PWM. I have been trying a few OLED Laptops, was very excited for my X9. Opened and used it for 4 day. I cant looked at the screen for more the 5-10 minutes with out have eye pain that last hours. Now i do notice this X9 has 1200hz so now wondering why the screen was bothering my eyes? any help would be great as for it my favorite laptop ever.
