Lenovo Yoga Slim 7i Pro X laptop review: Elegant creative laptop with Nvidia GeForce RTX

[NikoB]

People don't work on smartphones. At least adequate people do not look at the screen of an AMOLED smartphone for hours. People work for hours on laptops - this changes everything radically.

Current attempts to eliminate flicker on AMOLED laptops are immediately ruining their most vaunted advantage of "infinite" contrast and super black. Plus poor color depth and color reproduction with dc dimming scheme. Plus, their resource is always 1.5 or more times lower than that of IPS backlights. Which will lead to the need to change the screen after 3-4 years. Even the best AMOLED options, as local reviews show, are calibrated much worse in hardware than IPS, and moreover, AMOLED calibration floats much faster. Plus, their color resolution is often lower than that of IPS.

Today they can be used only in extremely narrow areas. For home and work, AMOLED screens should be avoided in every possible way, especially for children who are just developing the nervous system.

miniLED is complete bullshit even with 4000 zones. Halos around the letters on the borders of the zones are not removable. The only hope for microLED, but there will most likely also be flickering and glossy matrix - and then there is no point in them either.

As IPS was the best option for the eyes, it remained 20 years later ..

The main thing is that the contrast should be from 1500:1, all shades are visible, including dark ones, good real viewing angles from 178/178, in terms of contrast and brightness and the response time for B2W/G2G is no more than 10ms. Such panels are worth taking. But they are few and expensive. There is a shortage of quality IPS panels on the planet, like everything else.

[An update! (AMD version)]

Does anyone know if the limited performance on battery, is like a Lenovo thing or specific to this model thing or windows 11 or ryzen 6000 thing? It's especially bad on ryzen 6000 models.

After some further testing, I've discovered or come to realise that it does indeed quite seem to quite severely limit performance while on battery. Doesn't matter if on battery saver or balanced profile.

Even lighter games seem to lag and installing larger apps take a lot longer than when connected to charger.

I wonder if there any laptops that do better in this regard. (Besides M1 MacBooks I am unaware if there are any windows laptops that can run full power or close to it, while on battery alone)

Are there any laptops with a display which meets such a criteria?

1500:1, but only 170/170 (it very bad) and only 60Hz. Real contrast measured in review  only 1360:1, not 1500:1+

Look in the reviews for models that have managed to surpass all 5 key parameters. The search for the holy grail is endless when technologies are slowly improved or deliberately not introduced to the masses, and instead of the best versions of IPS, people are offered OLED with glare, flicker and color rendering problems and much less resource (i.e. they are also expensive to maintain). Or without flicker, but with a lower color depth and poor color accuracy and a sharp drop in contrast, although it is still many times better than on the best IPS. Alas, this is the current level of technology - science and production today cannot provide a mass production 100$-150$ flicker free screens with a contrast from 1500:1, matte and a response of no more than 10ms b2w/g2g, high uniformity of white and black (without backlit bleeding with 95%+ stability), viewing angles from 178/178 with less than 2 times the drop in brightness/contrast, resolution from 4k, brightness from 500 nits and a resource (up to 75% brightness) from 15k hours.

Keep searching...

The backlight uniformity in the tests is shocking and I'm surprised it wasn't commented on - 436 at the top of the screen and 372 at the bottom?! No matter how well you calibrate that, it's not going to be a useful display for colour-sensitive work.
