The screen is amazing
The type C connection is incredibly convenient, especially if you want to have good cable management
The type C power supply is very decent, it does mention that it is slow charged but the percentage never drops even with heavy use during work hours

The only possible downside is that it is not curved; if the room is quite bright, you might lose some detail at the corners of the screen

Quality screen with clarity and particularly competitive price. After buying 3 VA technology monitors (4k 32 inches), it was the turn of this one, which is IPS technology (which I admit I prefer both for work and for gaming). I bought this one specifically for work, so my review is oriented towards that.

Positives
+ Very good image (good clarity and beautiful colors)
+ Good brightness
+ Good build quality
+ Small bezels
+ Good native image settings
+ Lenovo's software for settings is very good. I didn't bother with any physical button, I installed the software and it was very easy to find the settings that suited me
+ Good connectivity with plenty of ports (1xDisplayport 1.2, 1xHDMI, 1xUSB-C) and several USB-A ports
+ Has AMD freesync; relatively low response time so it's also good for gaming
+ Its price for IPS 32 4k/60Hz is the lowest on the market so it is automatically classified as a VFM product

Negatives
- The buttons on the right front of the screen, which could be considered outdated for some
- The brightness could be a notch stronger for my eyes
- There is no setting for the screen's sharpness
- The speakers are indeed terrible but it's enough for me that they exist
- Not suitable for console gaming. I connected the PS5 and the image was really terrible.

Finally, I should mention that instead of the classic HDMI port, I used the Displayport (I bought an additional Powertech Cable DisplayPort for €5.34) and the image became even better and clearer

For office use and programming, it is very good for its price.
The USB-C function is very convenient, as I often use it to connect my Samsung S21, which has audio and video output, charges, and connects a keyboard and mouse via USB-C. In Samsung DEX mode, it can be comfortably used as a desktop with very good results for almost all Android applications.

I give it 4 stars only because the built-in speakers are unacceptable. Chinese Christmas Santa Clauses produce better sound.

Without having experience with similar screens (32 inches/4K), my screen looks very good. Especially for its price. I had a Dell U2711 until now, the Lenovo has a higher ppi, 140 instead of 109. The difference is impressive. Also, the coating is not as matte as Dell's, Lenovo does not mention 3H in its specs, just "matte", many others mention it as 3H but it probably isn't. I don't have it in a demanding lighting environment, and I don't have a problem with reflections. The contrast in the tests comes out at 1300, so it's a little higher than the typical. Detailed test here: https://mezha.media/en/reviews/lenovo-l32p-30-monitor-review/ There is backlight bleed in the 4 corners, I think it's typical for IPS. Otherwise, the color uniformity looks good. There are no defective pixels. Lenovo guarantees 0 bright but unfortunately up to 5 dark. Note that it supports DP1.4 and not just 1.2 as the specs say. Lenovo's program for handling the screen is very good, you don't need to mess with the buttons and the classic menu, and it's available in the Microsoft Store. The USB hub plays in 2.0 by default, but you can change it to 3.0 from the menu and the program. I work with it at 125% scaling, instead of the recommended 150% by Windows. I am very satisfied with the purchase (383 euros).

Very good screen, for the price of 339€, it's a shame I didn't get a second one.

In the package, there was also a cable (I assume a thunderbolt 3 cable with 20Gbps) one meter long. Note that the cable alone costs more than 30€.

The IPS panel is very good, I didn't have any issues with dead pixels, I don't see any bleed.

The menu is not user-friendly, but in the end, it gets the job done. The speakers are clearly much worse than those of the Samsung M7, for example.

Used with an Intel Mac. The large size doesn't strain the eyes.

The screen for the money I bought it for 340€ is excellent... Out of the box it blinds you with its brightness! Lower it to 10%. Automatically, the windows go to 150% DPI, almost as much as the 100% of the 2k AOC 31.5" that I also own. Testing at 100%, everything becomes very small and difficult to use. After a week, I prefer the 150%.
Unfortunately, many programs are not ready for 4K. Neither are the win10..!
I mainly work with autocad and unfortunately, you can only work with it at 150% DPI. That is, like the 2K monitor! For years, I have been working on a 2K 31.5" AOC VA, not IPS, which costs 200€, and so far I am very satisfied, especially in autocad, it is the most comfortable monitor for many hours of work... due to contrast and good black, I feel much more comfortable working with the colors of the linear design with a gray background... In text applications, the blurriness starts, which is normal, here the IPS 4K is crystal clear but still something bothers the eyes! Before the 31.5" 4K IPS, I also used a 29" ultrawide 75hz with 1080 IPS resolution, which was always more tiring than the VA, I thought it was the resolution at first until I got a 144hz TNT 1080 AOC 25" for the small one, which doesn't have the colors of the IPS but in my eyes, it is much more relaxing, with the blurry texts, here even the IPS 1080 struggles with the text. From my experience, I believe that IPS is not suitable for prolonged use, they are only impressive...! I still have to try a 4K VA leaving a window for IPS above 60hz or Eizo!
Back to Lenovo, it is very difficult to adjust it to your needs, I used the extra Nvidia color settings 32bit 10bpc RGB FULL, lowering the gamma a bit. It is very important to use Displayport and not just HDMI, this way the image is clearer, I would also recommend V1.4 or certified V1.2. For example, the letters of the icons with the right cable appear three-dimensional and in one shade, with HDMI they had a dirty feeling. (On the OLED TV, I now use HDMI v2.1 for Nvidia TV Shield Pro and Vodafone TV (for terrestrial channels, I have better image quality than the built-in LG) and the difference from the random HDMI is really noticeable).
Unfortunately, for office work, Windows, and software in general, struggle to take advantage of 4K, also the hardware needs attention, for example, the i7 6700/6th Gen can't handle it... you need a relatively new processor with integrated graphics or a graphics card!
My opinion is to look for expensive monitors and for now, go for 2K.

Only for its cost, I give it 5 stars out of 4!
I continue to use it at 150dpi, its high resolution shows its teeth... with its clarity in text, images, and so on, the eye starts to get used to it, although it's not like the relaxing 2K VA! Maybe a 4K VA would be a better choice!

For so long, the screen struggled and so did I... with integrated graphics from the processor... now with a graphics card, even PC crashes have stopped... am5 7900x doesn't work for a 4K screen, so you definitely need a graphics card!
