The screen is a gem. Real VFM. At 335 euros, you would be foolish to choose anything else. The screen would easily cost 600 euros for what it is.
2. The 4K image on a 27'' screen is very good. The common complaint about 4K, that it doesn't work well because it has very small icons, fonts, etc., didn't bother me at all because it has infinite space. Also, you can zoom in on fonts while browsing and it doesn't bother you at all.
3. The response time is perfect, around 6-10ms. Those who think they will get a screen with 1ms response time are actually getting 3+ms, so the differences are minimal and you won't see any difference even in games.
4. 60 hertz is enough for all uses, even for games, unless you are a professional Counterstrike player and make money from it, then yes, you want more. For the strategy games I play online, it's more than enough.
5. If someone plays very heavy games, it's better to get a 2K screen since 4K is a pain for graphics cards and FPS, and in essence, you won't notice much difference in resolution in games because you're focused on the game. But FPS is important... that's why for hardcore gaming, go for 2K.
6. A big plus is the USB-C 60w charging that I have a permanent cable for.
7. The stand is very stable.
8. Be careful, to get 4K 60Hertz, the cable must be High Speed HDMI 2.0 or higher. I had an old one that the screen wasn't recognized by the laptop, and after trying, I temporarily lowered it to 30hertz and then after two days, I got another cable.
9. The speakers have good sound, not crazy things, with low to moderate volume, enough for games, YouTube, etc., definitely better sound than the laptop.
10. Download the Dell program to play with various elements, etc. Link below.

11. The colors are good out of the box, but for better or worse, download the ICC Profile from rtings.com if you do editing in Photoshop, etc.
