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.

AI summary — not a quote
The ASUS PG27UCDM is frequently cited as a top-tier 27-inch 4K QD-OLED gaming monitor, praised for its exceptional color, contrast, and 240Hz refresh rate. Users often describe the jump from IPS to this panel as a "night and day" difference in visual quality. While it is highly regarded for its inclusion of modern standards like DisplayPort 2.1 and Dolby Vision, it carries a significant price premium and has drawn some criticism for VRR flicker and potential panel uniformity issues like vertical banding.
Pros
- Stunning 4K QD-OLED visuals with infinite contrast and vibrant colors
- High 240Hz refresh rate providing excellent motion clarity and responsiveness
- Support for DisplayPort 2.1 (UHBR20), allowing 4K/240Hz without needing DSC on compatible GPUs
- Includes Dolby Vision and a functional Black Frame Insertion (BFI) mode
Cons
- Significant price premium compared to similar models like the XG27UCDMG
- Reports of noticeable VRR flicker which may cause eyestrain or headaches
- Vertical banding issues reported on some units
- High reflectivity due to the glossy screen finish

I went from a 165hz 1440p ips acer predator to a pg27ucdm and it was night and day. Literally had the whole family just staring in awe.
pg27ucdm imo
I find it funny how the PG27UCDM is touted as the best gaming monitor on rtings but has a ton of VRR flicker. Sure the other specs are good but the thing most important to minimise eyestrain, headaches and even motion sickness letting you game for longer in prime state isn't put into consideration at all from what it looks like in their ratings.
The PG27UCDM is a complettely different monitor than the PG27AQN. You can't group them together.
PG27UCDM/XG27UCDMG are both incredible picks.
