The monitor and video card also work smoothly together thanks to the FreeSync Premium PRO technology, which reduces screen tearing. You're less bothered by strained eyes thanks to the blue light filter and flicker-free technology. Do you often change position?

Maximum performance without unnecessary features.

Very good contrast and color reproduction (DCI-P3 99%!)
High refresh rate
HDR600 does its job very well
No smart options

I was torn between the Samsung Odyssey G7 LS27DG702EUXEN and this LG monitor, both in roughly the same price range. Both are strong screens, but they target different types of users. After extensive testing, I chose the LG. Below, I'll explain why; hopefully, it will help you with your choice too :).

Samsung: a monitor that's almost a TV

Pros:

Good value
Built-in speakers
Smart platform (Netflix, TV, apps)
Lots of features and settings

Cons:

You get a lot of extra features, but that comes at the expense of the focus on image quality
Lower contrast and less vibrant color reproduction (mix of DCI-P3, RGB, and Adobe)
The IPS panel is noticeably lower quality than the LG's
Less focus on pure performance

In summary:

Ideal if you want a single device that serves as both a gaming monitor and an entertainment screen.

LG: Maximum performance, no bells and whistles

Pros

Focused on pure image quality and gaming
Higher quality IPS panel (Nano) with better colors and almost OLED-level
Higher contrast and brightness
Color reproduction = DCI-P3 99%!!!
Extremely high refresh rates, ideal for PC & console gaming
Better HDR
No unnecessary smart platforms: just plug and play

Cons

No built-in smart features
No built-in speakers/remote control

In summary: The best choice if you're looking for pure performance and image quality within a similar price range.

Final conclusion Both monitors are good, but they offer something different: -> Do you want to game and also use Netflix, TV, and smart features? → Go for the Samsung. -> Do you want the best image quality and performance without unnecessary extras? → Go for the LG.

That was the deciding factor for me: I simply wanted a top-notch monitor for gaming, not a TV-like screen that always started up with a French channel. That's why I chose the LG.

Hope this helps :)

This screen is highly recommended! The design is good. Everything you play is very sharp and games play quickly. If you often play games, this screen is really great. The refresh rate is very fast, which makes everything run very smoothly. I often had this problem with my old screens. The resolution also leaves nothing to be desired. Everything is crystal clear. In addition, the screen was set up within 5 minutes. So no time is lost! I can therefore recommend this screen to every gamer, or anyone who just wants a good screen! It takes your gaming experience to the next level.

Good Monitor

price
monitor interface
beautiful picture
software annoyances

For the price a very good monitor. IPS and no Oled no problem. There are some problems with the HDR and windows. LG should solve this with an update. In terms of pixel lottery I was able to exchange my first one at coolblue without any problems. I had 1 white pixel. Second monitor was perfect. Hence pixel lottery. All monitors of all brands suffer from it. just a very good monitor. the operation on the LG monitor can not compete with any other brand.
