Head-to-head
Alienware AW3423DWF vs Samsung G85SB: Samsung charges a USB-C laptop and streams without the computer
The short answer
Choose the AW3423DWF for a desktop-focused ultrawide OLED setup with full-size DisplayPort connections. Choose the G85SB for USB-C laptop video, up to 65-watt charging and streaming without the computer. The small 165Hz versus 175Hz gap is not the main reason to choose.
Before you choose
The reasoning and the trade-offs
Ten extra hertz saves about 0.35 ms per refresh
The interval is about 6.06 ms at 165Hz and 5.71 ms at 175Hz.
What this is based on
1000 ÷ 165 − 1000 ÷ 175 = 0.346 ms. This is not a tested input-lag advantage.

What matters in practice
The differences that matter
Ten extra hertz saves about 0.35 ms per refresh
The interval is about 6.06 ms at 165Hz and 5.71 ms at 175Hz.
How we reached this conclusion
1000 ÷ 165 − 1000 ÷ 175 = 0.346 ms. This is not a tested input-lag advantage.
A 65W laptop changes the winner
Only the G85SB combines native USB-C video and a stated 65W charging ceiling.
How we reached this conclusion
The AW3423DWF has no USB-C video input. The Samsung's exact LS34BG850SNXZA page specifies video over USB-C and 65W output.
Switching inputs can lower the Alienware ceiling
The AW3423DWF drops from 165Hz through DisplayPort to 100Hz through HDMI at native resolution.
How we reached this conclusion
Dell lists both limits. The HDMI interval is 10 ms, compared with 6.06 ms through DisplayPort, before considering other latency.
Choice A
Alienware, AW3423DWF
34 Curved QD-OLED Gaming Monitor

Meaningful differences
What changes the fit
| What changes | Alienware 34 Curved QD-OLED Gaming Monitor | Samsung Odyssey OLED G8 34-inch | Why it matters |
|---|---|---|---|
| Native resolution | 3440 × 1440 | 3440 × 1440 | The pixel workspace is unchanged. |
| Maximum refresh | 165Hz through DisplayPort | 175Hz | The maximum refresh interval differs by about a third of a millisecond. |
| Curve | 1800R | 1800R | The curve specification does not separate them. |
| DisplayPort connector | Two full-size DisplayPort inputs | Mini DisplayPort | The Samsung requires the appropriate smaller connector or cable. |
| HDMI connector | Full-size HDMI 2.0 | Micro HDMI 2.1 | Check the actual connector, not just the HDMI generation. |
| USB-C video and charging | No | Yes, up to 65W | The Samsung is the one-cable laptop option in this pair. |
| Computer-free streaming and speakers | No smart platform or speakers | Smart apps and speakers | The G85SB can handle more evening viewing on its own. |
What you give up
Every choice has a cost
If you choose Alienware 34 Curved QD-OLED Gaming Monitor
- There are no built-in speakers or USB-C video input.
If you choose Samsung Odyssey OLED G8 34-inch
- This is the G85SB, not the later G85SD with a different port layout.
What matters in practice
How to make the call
The cable layout is a genuine buying difference
The Alienware uses full-size DisplayPort and HDMI, while the G85SB uses Mini DisplayPort and micro HDMI. That changes which cables fit physically. Check the exact G85SB listing because later Samsung OLED G8 revisions use different layouts and should not be treated as the same monitor.
A laptop and evening streaming favor the Samsung
The G85SB can take a compatible laptop's picture over USB-C and supply up to 65 watts. Its smart apps and speakers also work without the PC. Those are useful conveniences, but a laptop needing more power still requires another charging plan.
The refresh headline should stay in proportion
Both offer the same ultrawide resolution and an OLED picture. The difference between 165 and 175Hz is small in refresh-interval terms. A more important limit is the Alienware's 100Hz ceiling through HDMI, so desktop users should plan around DisplayPort when they want its full native refresh rate.
What this comparison cannot tell you
- Refresh intervals do not establish measured motion clarity or input lag.
- Regional Samsung specifications are used only where the exact LS34BG850SNXZA hardware code matches. App availability can change.
