LG Gram SuperSlim (2023) review: 990 gram laptop with long battery life and OLED display

[andrew silver]

A pity that the review is wrong about PWM - it does infact have PWM - more under 50% but also some still at all brightnesses.
I have to return it for this reason.

This site is full of strange reviews where they claim that there is no low-frequency PWM or it is in the region of 50-100 kHz, although the datasheets for the panels indicated in the review, for example, clearly say that the maximum PWM frequency on them is no more than 20-30 kHz.

So you need to treat these reviews very carefully, and carefully monitor the overall picture, which an ordinary person who grabs one interesting review for reading by chance simply cannot do due to a lack of understanding of the weak points of the reviews.

There are many nuances that only professionals and extremely experienced readers understand.

So, when it comes to these reviews (and not only on this site), you need to be very careful, carefully monitoring the overall picture, which the average person, having grabbed one interesting review for him to read, by chance, simply cannot do, due to a lack of understanding of the weak points and nuances of testing and design of reviews by the authors.

There are many nuances that only professionals and extremely experienced readers understand and which simply remain behind the scenes.

Unfortunately, even specialized forums with threads on a specific product model, hundreds of pages long, sometimes cannot give clear answers due to the fact that more than 90% of their participants are complete amateurs (and mostly idiots), asking the same primitive questions in a circle questions, and when asked to check something, if they suddenly find themselves one of the first to buy a new product, they remain lazy, stupid and selfishly silent, not wanting to help the community, thereby, to their own stupidity, limiting the possibilities of their own choice, subsequently, new products, i.e., "shooting themselves in the foot" in the future. As a result, you can only find out something reliably by conducting a very complex cross-comparison of many reviews on the Internet and carefully, in parallel, analyzing the datasheets of components in order to understand where the authors are clearly lying. Or by purchasing a product, not just one copy, but several with different compositions of components, in order to understand how fraudulent manufacturers manipulate their composition in batches. And who can afford this, even if such sites do not do repeated and multiple random tests in different batches and after a certain time. In fact, all reviews on the Internet are a profanation of professional testing, unless there is a methodical recheck of each subsequent batch, because Even if we exclude the bias of reviews, when the product is clearly transferred by a manufacturer interested in a certain coverage of the product, the absence of random, selective, repeated testing at a certain time interval, in different batches, excludes buyers from understanding the real picture of the quality of the product in batches and in general.

That's all valid but OLED without PWM is highly unusual, especially on a laptop, and yet the reviewer doesn't question or remark about this test result.

It takes nothing more than an iphone app to see that PWM is very present..maybe the review sample was 'rigged' as you say.

Please explain! What datasheets? Where? How do I understand that there must be PWM? Why is it impossible that the datasheet is wrong and the review is right?
