Lenovo ThinkPad P1 G6 review: 80 W GeForce RTX 4080 for ultrathin workstation

[JRS]

Even if you're right, black holes clearly result in noticeable dark streaks in light scenes. What the authors of reviews have already noted more than once, i.e. the picture is not identical in monolithicity, the same in resolution of the IPS panel

Do the reviewers have any actual evidence that this is the result of the subpixel structure and not some other reason?  Are the reviewers noticing the same effect on other displays such as phones that typically have even less monolithic pixel structures? 

This is a 282 PPI display that is considered retina from 11" and the gaps are only 1 subpixel.  I am very skeptical that any reviewer could notice a difference in brightness given these gaps are below a perceptible size.

I think it's more likely that either 1) reviewers do not have the refresh rate synchronized to the PWM frequency which will cause motion issues, and/or 2) manufacturers such as Lenovo and HP use an add-on film touch layer which is visible over the panel.

Smartphones have ppi much higher than 300, so it's impossible to notice anything there. For example, at 300 ppi I still see problems with fonts, compared with 440 ppi+.

Everyone's vision is individual, but since there are repeating pixel holes every 1 pixel on one side and every 4 pixels on the other, it is obvious that this will be noticeable and unpleasant for some, which is what the authors periodically note. Naturally, at 4k this will be less noticeable, but it is still noticeable if you look closely that the entire screen seems to be lined with barely visible dark lines on a white background.

In any case, IPS wins here. It also wins significantly in terms of color accuracy, because... according to local reviews, it is almost always impossible to calibrate AMOLED with dE less than 2. Specifically with this model everything is fine - dE<1.5.

But I can't imagine how to use this screen in practice with a terrifying PWM at a frequency of 60Hz...

[Ednumero]

If I fill the screen with blue, or draw 1px blue lines on a solid black background, I can begin to infer the offsets. During normal usage, it actually looks more homogeneous than those IPS panels that tilt their subpixels back and forth in alternating rows.

From a perfectionist's standpoint, I would also prefer that they weren't there. From a battle-picking perspective, there are other concerns that are more pressing to me, which we perhaps might all agree on.

Keep the market pressure on, folks.

[NikoB]

Judging by the fact that all manufacturers, without exception, deliberately ignore the possibility of installing IPS 4k@120Hz in mass-produced laptops, we are not putting any pressure on the market. They just don't care, they conspired to install only 2.5k rubbish, which is not compatible at the pixel level with either 4k video or fhd video and is also incompatible with fhd games to increase fps when the video card is no longer enough, and this is almost always the case from the moment of sale in native 2.5k (there is nothing to say about 4k).

4k panels are universal, they solve almost all problems with cloudy fonts caused by Google in Chrome - there cloudy fonts are NOT disabled from version 50, but in FF the incorrect crooked cloudy anti-aliasing can be disabled with one setting, but even there the correct black-and-white anti-aliasing only worked up to 69 version, now you can only turn off anti-aliasing entirely, which is impossible in Chrome, where everyone who sits at screens with ppi below about 220-230 - 100% spoils their eyesight.

There are no obstacles (including price) to installing 4k@120Hz 16:10 panels in laptops from $900-1000; moreover, with their mass production, their cost will fall.

When running on battery power, there is no problem switching to fhd mode on a 4k panel without losing any sharpness at the pixel level - 4 4k pixels turn into 1 fhd, and the interpixel distance is still less than on a native fhd panel. But why do people sit with muddy fonts in chrome-like browsers from BP, if there is no problem in mass installing only 4K panels in 16-18" for several years now? Why are there no screens left on smartphones even in cheap models with ppi below 300, and this is such a shame in laptops?

I understand why 4k is not enough on monitors (you need 6k-8k), but in laptops long ago these bastards had to make massive 4k 16:10 screens with a ppi guaranteed above 230. Interfaces have long allowed this, even eDP1.4b (by the way, a shame Intel - in Meteor Lake again only the shameful eDP1.4b, but not 2.0+!).

[Neenyah]

Quite literally nothing is true nor accurate in that wall of text, pretty impressive. Especially not this part:

When running on battery power, there is no problem switching to fhd mode on a 4k panel without losing any sharpness at the pixel level - 4 4k pixels turn into 1 fhd, and the interpixel distance is still less than on a native fhd panel.

At 720p four pixels are binned into one pixels down to perfect integer number with 2560x1440 so try to use 1280x720 on a 1440p panel. You certainly won't manage to go "without losing any sharpness at the pixel level" and everything will look like s***.

I mean if you are lazy to change your screen resolution to 50% lower one, just literally take a screenshot of your screen, paste it in Paint, resize it to be 50% smaller, then save that screenshot and open it on your native resolution screen and make it fullscreen. It looks like crap. It's pretty clear that you don't have a 4K screen, lol. That is obvious from your point of looking at everything through 100% scaling; good luck using 100% scaling with 4K at 16", haha. Most people use 200% and that is effectively FHD, just much sharper.

Also just switching to a lower-resolution mode most definitely won't help with battery life because the 4K panel is still taking higher amount of power (than a FHD panel) regardless of what data is sent to it. The power savings will not come from the display when you lower the resolution; the saving come from the GPU because it doesn't have to render as many pixels. Switching to lower refresh rate will help though.

But then again that is not the case anymore since about Intel HD 520 (which was working flawlessly with 4K) so I understand why you think it is as that GMA 950 in your 2008 MSI laptop is clearly struggling even with its own 768p native resolution; perhaps it is time for an upgrade, NikoB?

Edit: I am still waiting for your link/proof of that Huawei laptop which was available in your mythical country at the start of the summer of 2023, solid 5 months before they (Huawei) released it in China or anywhere else. You call me a liar and then when asked for proofs you simply run away like a rat, never to be found in that thread again 😁

Must be nice to live in a country where Chinese OEMs sell their own products many months before they even release them in their own market (China).

I have already proven more than once that you are lying and I can easily prove it again.

Lmao, so do it then. I am lying, Notebookcheck is lying, hell even Huawei is lying and they were secretly selling this laptop in your super-important country FIVE MONTHS before they released the product in China. All links are lies, only your invisible links and sources are THE truth 😂

But I can't imagine how to use this screen in practice with a terrifying PWM at a frequency of 60Hz...

Phone panels are not a good comparison because they are known to have PenTile or other layouts that do not have independent R,G, and B subpixels for each pixel.

The white background issues on this model are due to Lenovo's add-on film touch layer.  The layer is visible up close and looks like a pattern of repeating dots in a checkerboard pattern.  I see no such uniformity issues on OLED panels without Lenovo's AOFT layer.  I've noticed AOFT layers on OLED panels from some manufacturers (Lenovo, HP) but not others (Razer, Alienware, Gigabyte).

Color-fringing on text occurs on all displays regardless of subpixel layout.  ClearType and other subpixel rendering algorithms are just more effective at covering it up on RGB-stripe layouts because those are the only layouts they support.  Regardless of layout, the fix is always the same - manufacturers need to release higher DPI displays.

I can't notice any flicker on this display, even at 60 Hz.  By comparison, if I turn on 60 Hz black frame insertion on my OLED TV that is extremely noticeable.  I don't know what the pulse coefficient is for each cycle but it definitely does not appear that the pixels are fully cycling on/off.

Motion on this display appears very clear - that's a benefit of its PWM.

The battery life and power consumption data don't seem to match to me. The P1G4-20Y4S0KS00 also has a 4k screen with similar power consumption data except for the high load scenario. How come the P1G6-21FV001KUS can only last 4hrs of wifi-v3 while the P1G4 has 7hrs.

Gimmick, lol. That's the charger for Lenovo's docking station, they usually provide them for review units. Slim tip 230W is its normal charger and it is small and light. Any 90W+ USBC is also charging perfectly fine.

HAHAHA @ 0.6kg
just a brilliant example of someone who doesn't know what LAP TOPs are for
now go on to usual stupid "you have to go to gym if you can't carry it" rant
and then those guys just never use their "laptop" outside
and no one knows why they've invested in laptop instead of desktop

Any 90W+ USBC is also charging perfectly fine.

yeah, keep using underpowered power bricks if you want your battery dead faster
then replace it with a cheap chinese aftermarket cause your laptop is outdated in 2 years and lenovo isn't producing anything for it anymore

Yeah, 2.4 kg combined weight (1.8 + 0.6) is too extreme to carry around. It is much easier to carry 2.4 kg with other laptops, no matter how it's distributed, like the M3 MBP 16 with 2.1 kg + 0.35 kg charger. 2.4 kg there is clearly far lighter than 2.4 kg here.

You are not a target audience for ThinkPad(s) and have no idea how are they being used so why worry about them at all? And speaking of myself, I own a 1.1 kg "heavy" X1 Carbon and when I'm not at home I carry my light and tiny 65W Anker 735 (about 145 grams or so).

Any 90W+ USBC is also charging perfectly fine.

Lol, so now charging at lower power is destroying battery, for the first time in the history. Nice.

[sad]

like the M3 MBP 16 with 2.1 kg + 0.35 kg charger

For that one you can leave charger at home or hotel. And this one is a 4hr battery life web browsing machine.

Why do you keep arguing with everyone, you've already lost like 6 messages ago.

[Neenyah]

When your ego is so insecure that you look at normal talk about a laptop as winning or losing. 13 y.o. detected.

[Ron1]

Lol, so now charging at lower power is destroying battery, for the first time in the history. Nice.

Working and charging with underpowered charger at the same is really bad for battery. As consumption goes over charger capacity notebook dips into battery in short charge-discharge cycles which is bad. Even worse if it is already charged to 100% and it immediately tries to fill that power spike back into battery when consumption normalises, thus creating a short charging spikes at around full battery.That's battery killer behaviour. Also underpowered chargers tend to emit much more heat.

[sad]

Hmm, speaking of "ego" and "13 y.o." behavior, if its not about winning or losing for you, why did you even reply with insults only.
I'm not interested in this kind of conversation.
