When working in the near zone (50-70cm), pixelation is clearly visible. That is why the minimum resolution for 17.3 is 2.5k, but because 2.5k is the most idiotic possible resolution for both video content and games - the best is always 4k@120-144Hz. And there are plenty of 4k@60Hz options on the market with a contrast of more than 1200:1 - at least 3 panels from BOE:
NE173QUM-N42
NE173QUM-N63
NE173QUM-N61
They cost depending on the grade - 150-220$ at retail, and not in large wholesale, where their price is at least 2-2.5 times lower...

They psref spec of 800:1 is likely from when they were still using the AUO panel, which has a typical contrast of 800:1 in the datasheet. (in practice it achieves over 1000:1, positive surprise)

Calling 127ppi huge pixelization is a bit of an exaggeration but I agree with the general laziness on the laptop market. 120Hz+ should be standard by now, even for office work. FFS they still use lots of TN matrices and the market is saturated with horrible 45% NTSC panels and low brightness models, even in more expensive notebooks.

Quote from: MichelS on March 14, 2023, 14:37:15Sorry, the minimum contrast ratio is actually supposed to be 900:1, not 800:1.

No, by psref is typical 800:1 from Lenovo this series. View angles is 170/170. It's not good. And huge pixelization with 1920x1080 only for 17.3". For such a diagonal, at least 2.5k is required, and preferably 4k@120-144Hz, as a standard office/multimedia/game panel for all laptops without exception. There should be no fhd/2.5k panels left on the market, only 4k, which, at the level of their own electronics (and not video drivers), easily switch to fhd@60-144Hz mode when it is necessary for some reason for the sake of performance in 3D or because of the need for compatibility with old software that does not work well with high ppi.

It is not clear to me why there is no understanding of this and why the greed of manufacturers in the notebook sector is so great. With large supply volumes of 4k@120-144Hz 15.6"-18" panels, their prices will fall quickly, as they have fallen on screens for smartphones with high ppi.

This model really does not have the opportunity to look at MTM options for panels from the factory with the exact names, which is sad. Even in the above photos, the matrix model is not visible - the resolution of the images is too low.
Previously, it was easy to find out from Lenovo by MTM all the panel options for a series ...

Sorry, the minimum contrast ratio is actually supposed to be 900:1, not 800:1. I checked the datasheet again.
Here is a screenshot of the optical specs:

Quote from: NikoB on March 14, 2023, 13:28:31On the Lenovo website, you do not need to enter the serial number, the MTM code is enough to find out the panel options.

Please note that the datasheets on the panel indicate typical contrast, not guaranteed. If you want 1200:1+, then you must specify this at the time of purchase under certain consumer laws. Then the seller is obliged to give you just such a model or report a real contrast that does not meet your requirements. But it depends on the legislation of a particular country.

The MTM (82RQ003CGE) does not help for this model, you only get "DISPLAY L 82RQ 72%" which is another umbrella term. For the 17ABA7 you need the serial number to show the specific panel/manufacturer which is used. Judging from the subpixel photos, the reviewed Notebook is using a BOE Panel because the green subpixels look different on the AUO panel. I'm aware that the typical contrast is not guaranteed but it is not supposed to go below the minimum spec in any case. I own the datasheet and it says the minimum contrast is 800:1.

Hallo! Welches Panel ist denn in eurem getesteten Laptop verbaut, der Kontrast scheint echt mies zu sein?
LEN173FHD ist bloß ein übergeordneter Begriff welcher mehrere Panels umfasst. Wenn man bei der Lenovo Website die Seriennummer des Laptops eingibt, kann man unter "Teile" alle verbauten Elemente genau einsehen.
Eigentlich sollte der 17ABA7 gegenwärtig das BOE NV173FHM-N4K Panel nutzen, mit typ. Kontrast von 1200:1 (min. 800:1). Ältere Versionen des 17ABA7 nutzen in der Regel das AUO B173HAN04.3 mit etwas niedrigerem typ. Kontrast von 800:1, aber noch immer signifikant über den gemessenen Werten. Montagsmodell?
Würde mich über Antwort sehr freuen! LG

It seems like the fools at Acer made an almost perfect laptop in 2022 - Acer Aspire 5, but for inexplicable reasons they did not put 2.5k + screens in 17.3" models, where there is a full-fledged numpad. Thus, killing sales at times. As with the stupid 15.6", where, as usual (year after year, destroying sales of the series many times over!) they ruined the numpad, made an idiotic exhaust directly on a 2.5k screen with a critical panel temperature of only 50C.

It seems that in all companies in the marketing and development departments there are some villains who deliberately come up with Izuit ugly models in order to annoy customers as much as possible. As if evil fate hovers over the market, and not virtue ... Although this is probably a rhetorical question ...

Millions of people need 17-18" laptops at home with high ppi, but for inexplicable reasons they are not on the market.

Look at this pitiful product from Lenovo - a huge case, but a miserable keyboard, with buttons that are narrower in width and height with too short key travel. Not rendered arrows as in the Legion series. Poor set of ports is completely out of line with modern requirements. Processor outdated by 2 years. Poor 16GB in dual-channel mode, and even with brake timings.

And for all this they ask for 800 euros?

Get at least a cheap 2.5k-4k@120-144Hz screen (it retails for $120-140!). Minimum 32GB of memory from factory in dual-channel or single-channel mode (i.e. up to 64GB in dual channel).

Normal keyboard, even better than from Thinkpad T16.

Full set of ports: USB40x2(Zen4 Phoenix internal ports) - one on left and one on right side + 2-3 USB-A Gen2 10Gbps + HDMI 2.1(48Gbps)+RJ45(2.5+ Gbps) ports. Fast SD+ (200Mb/s+) reader. And 2 4-pin audio outputs on the left and right, so that it is convenient for both right-handers and left-handers + optical spdif separately for galvanically decoupling the DAC from laptop power circuits, since there is plenty of space on the side. And of course, leave the power supply with an angled round plug, giving backup power via usb-c, who needs it.

Cooling system with normal weight radiators and exhaust at the rear, not at the screen. Able to be silent up to 40-45% of the load on all cores.

And sell it all for 1000-1200 euros directly from the factories from the manufacturer, bypassing speculators (in the modern world, all intermediaries should be eliminated long ago, it is they who form prices that are many times overpriced relative to the cost of goods from the factory) and providing a service network for warranty repairs - demand will be huge...
