At native resolution, HDMI maxes out at 100Hz, compared with the 165Hz DisplayPort ceiling.
Side by side
Alienware AW3423DWF vs Samsung G85SB: Samsung streams with no computer needed and charges a USB-C laptop
Quick verdict
A desktop-focused ultrawide OLED setup with full-size DisplayPort connections suits the AW3423DWF. USB-C laptop video, up to 65-watt charging and streaming without the computer suit the G85SB. The small 165Hz versus 175Hz gap should not be what decides it.
Before you buy
Why, and what it costs you
About 0.35 ms per refresh is saved by ten extra hertz
At 165Hz the interval is about 6.06 ms, and at 175Hz it is 5.71 ms.
Where this comes from
1000 ÷ 165 − 1000 ÷ 175 = 0.346 ms. No tested input-lag advantage is shown by this.
The catch
Samsung Odyssey OLED G8 34-inch
You need the right cables or adapters for Mini DisplayPort and micro HDMI.

In practice
Differences you will notice
About 0.35 ms per refresh is saved by ten extra hertz
At 165Hz the interval is about 6.06 ms, and at 175Hz it is 5.71 ms.
How we worked this out
1000 ÷ 165 − 1000 ÷ 175 = 0.346 ms. No tested input-lag advantage is shown by this.
The winner changes with a 65W laptop
Native USB-C video and a stated 65W charging ceiling come together only on the G85SB.
How we worked this out
No USB-C video input exists on the AW3423DWF. The Samsung's exact LS34BG850SNXZA page specifies video over USB-C and 65W output.
The Alienware ceiling can drop when you switch inputs
At native resolution, the AW3423DWF goes from 165Hz through DisplayPort to 100Hz through HDMI.
How we worked this out
Both limits are listed by Dell. Through HDMI the interval is 10 ms, against 6.06 ms through DisplayPort, before other latency is considered.
Option A
Alienware, AW3423DWF
34 Curved QD-OLED Gaming Monitor
Games that support a wider field of view suit this curved ultrawide OLED. If you can do without built-in streaming apps, the full-size DisplayPort sockets make the AW3423DWF a practical desktop choice.

Spec by spec
Where they really differ
| Spec | Alienware 34 Curved QD-OLED Gaming Monitor | Samsung Odyssey OLED G8 34-inch | In practice |
|---|---|---|---|
| Native resolution | 3440 × 1440 | 3440 × 1440 | Pixel workspace stays the same. |
| Maximum refresh | 165Hz through DisplayPort | 175Hz | About a third of a millisecond separates the maximum refresh intervals. |
| Curve | 1800R | 1800R | The curve specification gives no way to tell them apart. |
| DisplayPort connector | Two full-size DisplayPort inputs | Mini DisplayPort | The appropriate smaller connector or cable is required for the Samsung. |
| HDMI connector | Full-size HDMI 2.0 | Micro HDMI 2.1 | Look at the actual connector and not only the HDMI generation. |
| USB-C video and charging | No | Yes, up to 65W | In this pair, the Samsung is the one-cable laptop option. |
| Computer-free streaming and speakers | No smart platform or speakers | Smart apps and speakers | On its own, the G85SB can handle more of the evening viewing. |
Trade-offs
What each pick costs you
With Alienware 34 Curved QD-OLED Gaming Monitor
- Built-in speakers and USB-C video input are both missing.
With Samsung Odyssey OLED G8 34-inch
- The G85SB is what's described here. The later G85SD has a different port layout.
Decision guide
How to decide
The AW3423DWF is for a desktop-focused ultrawide OLED setup with full-size DisplayPort connections. The G85SB is for USB-C laptop video, up to 65-watt charging and streaming without the computer. Don't let the small 165Hz versus 175Hz gap drive the choice.
The cable layout really does affect the purchase
Full-size DisplayPort and HDMI are on the Alienware, whereas the G85SB has Mini DisplayPort and micro HDMI, so different cables physically fit. Look closely at the exact G85SB listing, since later Samsung OLED G8 revisions use different layouts and are not the same monitor.
The Samsung suits a laptop and evening streaming
Over USB-C, the G85SB can accept a compatible laptop's picture and supply up to 65 watts. The PC isn't needed for its smart apps and speakers either. Those conveniences help, but a laptop that needs more power still needs another charging plan.
Keep the refresh headline in proportion
The ultrawide resolution and the OLED picture are the same on both. Between 165 and 175Hz, the difference is small in refresh-interval terms. The Alienware's 100Hz ceiling through HDMI is the more important limit, so desktop users who want its full native refresh rate should plan around DisplayPort.
What this page can’t tell you
- Measured motion clarity and input lag cannot be established from refresh intervals.
- Only where the exact LS34BG850SNXZA hardware code matches do we use regional Samsung specifications. App availability can change.
