According to our monitor expert
With the 27-inch UltraGear 27GX790A-B gaming monitor, you won't miss a single detail during fast games and you can enjoy a colorful image. Thanks to the Quad HD resolution, all details look sharp on the screen, Color are realistic and bright thanks to the OLED display and the HDR10 color technology. In addition, you can see your opponents appear quickly and sharply on the screen thanks to the 480Hz refresh rate and the low 0.03ms response time. 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? You can tilt, rotate, or adjust the LG UltraGear monitor in height easily to your liking.
Note: the maximum refresh rate via HDMI is 144Hz. For 480Hz gaming, you connect the monitor via DisplayPort.

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:
Cons:
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
Cons
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.

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.
