AI summary — not a quote

The Samsung Odyssey G5 Ultrawide is generally well-regarded as an accessible entry point into high-refresh-rate ultrawide gaming. Users frequently highlight its 3440x1440p resolution and 165Hz refresh rate as providing a significant immersion boost over standard 16:9 displays. While it is praised for its utility in both gaming and productivity—effectively replacing a dual-monitor setup—some users report technical frustrations, particularly regarding G-Sync compatibility and the performance demands the resolution places on mid-range GPUs.

Pros

  • High immersion for gaming due to the 21:9 aspect ratio
  • Excellent for productivity, functioning similarly to two monitors side-by-side
  • Smooth 165Hz refresh rate is highly valued for fast-paced titles
  • Confirmed compatibility with AMD FreeSync

Cons

  • Inconsistent or non-functional G-Sync performance reported by some users
  • Significant hardware demand; mid-range GPUs may struggle to maintain high frame rates at this resolution

My main monitor is 3440x1440 240hz, my main game rn is marvel rivals, but I go through other games as well.

I’d just upgraded my 75Hz 3440x1440p Ultrawide, which I’d used for some light gaming, graphic design and music production and moved to a Curved 180Hz 3440x1440p monitor and wanted to upgrade my components to get the most out of the monitor

This last black Friday I decided I liked it enough to replace it with an Alienware OLED 3440x1440. So my current setup is the Alienware OLED in the middle and the 1080p on the left on portrait, the 1440 on the right in portrait.

First I got a 240hz 1080p, then a 165hz 1440p, then I got a 3440x1440 widescreen VA panel for a ridiculous price to dip my toes into ultrawide. This last black Friday I decided I liked it enough to replace it with an Alienware OLED 3440x1440.

I would at least definitely recommend going some form of OLEd given the price of your system.

First of all, going oled on a monitor is a great choice but you might need to learn how to take good care of it.

Parent context: Hey man! I am currently using the Samsung G61SD and considering switching to the ASUS ROG Strix OLED XG27AQWMG Reply: In SDR, though, I’m really impressed with the ASUS, especially the brightness, clarity and overall picture quality. The glossy coating hasn’t bothered me at all.
