Hi,
laptopmedia review says it does have PWM at all levels. Help

any feedback appreciated

I mean the results of the reviewed model Lenovo Yoga 9i 14 2022

It looks like the AIDA64 memory speed test results are missing in the review.
I can see only the result of the previous model on the Gen 11 Intel CPU

I assume the laptop performance are the same with both chargers? I'm afraid the 100W will just be heavier and bulkier to carry around...

Taken from the review of the version with 2.8K screen and 65W charger:

"Interestingly, raw multi-thread performance is about 10 percent slower than the same model equipped with the same Core i7-1260P CPU but higher resolution 2400p display."

With a 65W charger the sustained power is only 28W while with a 100W charger the Yoga 9i sustains 38W.

I believe the difference in sustained multicore performance between versions is due to the charger, 100W vs 65W.

I assume the battery tests were with the 2k screen at 90Hz which would explain  the abysmal battery life. Oddly enough , the 2k Oled screen is listed. My Config:
Processor : 12th Generation Intel® Core™ i5-1240P Processor (E-cores up to 3.30 GHz P-cores up to 4.40 GHz)
Operating System : Windows 11 Pro 64
Memory : 16 GB LPDDR5-5200MHz (Soldered)
Solid State Drive : 1 TB SSD M.2 2280 PCIe Gen4 TLC
Display : 14" 2.8K (2880 x 1800), OLED, Glare, Touch, HDR 500, 100% DCI-P3, 400 nits, 60Hz, Narrow with Glass at £1390(£340 off).

Who in his or her right mind would expend 2000€ in such a laptop that even have a descent GPU. It's so overpriced.

Adding a whole column for dedicated media keys is such an insane choice. Compromising the typing space for keys I will rarely use (how often does *anyone* use these keys in a day?), for functionality that is already easily available..the choice is very hard to understand. I can only guess this was added based on some half baked market research. As a developer who uses a laptop keyboard much of the time this is kind of a deal breaker. Guess I'll pay 300+ more for a business laptop.

It's funny, the "first" Yoga 9 back in 2015 got the keyboard just right.

That's a perfectly usable layout. It even has Pause and Break. The couple of tricks they missed was System Request and a numeric keyboard like e.g. Dell used to do it via Fn in the main section (great for calculations or IP addresses). But it's hardly news that keyboards are getting worse and worse. At one time, Latitudes had such good keyboards that I preferred them to even rather expensive desktop keyboards. But that's long, long time ago. I wish Fn mappings were customizable. It's a missed opportunity.

Yes my bad, I meant to say RGB-OLED.

Iirc, WRGB is more color-accurate but dimmer in brightness and less efficient thus not suitable for mobile devices. QD-OLED is a step-up from both in terms of color volume reproduction.

> WRGB OLED

Interesting. Do you know where can I find the info about it being WRGB? I see the RGB subcomponents in the matrix photo, but no W unless the gaps between the blue chains are sparse white dots that remain dormant outside of HDR mode. I had generally thought those blank spaces were occupied by transistors, but I could be wrong.

On the other hand, I definitely see the W components in the WR/GB LCD matrix photo in the review of the old Yoga you linked. Of course, that display had perhaps principally-worse issues than color reproduction -- namely that it couldn't properly resolve full 3200(RGB)x1800 and was largely a means of inflating specs sheets (I digress).

I definitely agree WRGB (and WR/GB) arrangements run into color reproduction issues, regardless of whether that's the case in this particular unit.

It's funny, the "first" Yoga 9 back in 2015 got the keyboard just right. Before Lenovo watered down the entire Ideapad keyboard in efforts of expanding more overpriced Thinkpads into home consumer territory.

On a different note, it is important to add that color-accuracy of this display gets reduced to <70% DCI-P3 upon activating the 550 Nit HDR mode, unlike an equally bright LCD laptop display.
Just something to note for HDR photographers and video producers.

And no one wants / uses Fn + arrowkeys for home/end/page up-down, because for typists trying to highlight or jump words you also have to hold shift and maybe ctrl all at the same time. That's why they should be on dedicated keys.

I don't agree. I like dedicated keys but if I have to use Fn combination, this is the way to go. Plus I can easily use it without looking which is not always the case with dedicated keys, not to mention that different laptops have them in different places. I'm more annoyed by up/down cursor keys being small or the lack of grouping of F keys (the gaps between groups serve as indexes for orientation without looking, like the protrusions on F and J).

Really, the combination you need is shift+fn for selection. Which is hardly different from shift+ctrl for word selection except it uses thumb instead of the little finger (unless you live in ThinkPad land in which case it's the other way around). And frankly, I don't use page up/ down much at all (I can see the appeal of nicely placed dedicated buttons there - poor placement is one reason why I don't use page up/ down). I either scroll as I read along (if a display is too small) or use cursor keys to flip pages instead of page up/ down. Pages align perfectly (first line is in the exact same spot) and there is no silly animation, a page just flips practically instantly as it should be. Animations (e.g. in galleries) annoy me; what a waste of time.

These crappy layouts of modern time have made appreciate the logic of vim. I guess this is what you get when most people can't use a keyboard properly (including the useful shortcuts that involve F keys - I guess adjusting volume or brightness is more important). I digress.

Great display in this unit, and good info on it.

In the subpixel matrix photo, I do want to ask: is there a technical reason why it's captured at an angle? I figure it could be due to ease of positioning the unit on the microscope, but it does leave some open questions such as whether the blue lines run horizontally or vertically.

Assuming it's the same as the 16" WQUXGA panels, I think it would be safe to say they run along the vertical direction. This does create confusion in general, though, especially in the phone product space where a 45-degree matrix photo can incorrectly portray a Diamond PenTile panel as full RGB.

If the images need to be captured at such angles, then would it perhaps make sense to include a compass rose of sorts in the image to help clarify the axes? In any case I'm glad you (NBC) have kept up with including matrix photos in reviews. Really helps keep consumers informed and companies honest.

What the **** is that keyboard? Why have they added a bunch of stupid bull**** to a potentially perfectly good navigation column? And no one wants / uses Fn + arrowkeys for home/end/page up-down, because for typists trying to highlight or jump words you also have to hold shift and maybe ctrl all at the same time. That's why they should be on dedicated keys.
Okay computer ruined by bad input devices.
