The catch
Alienware 27 360Hz QD-OLED Gaming Monitor
Over HDMI, Dell specifies only 144Hz, while DisplayPort gets 360Hz.
Side by side
Alienware AW2725DF vs LG 27GR83Q: Alienware leans toward dark-game contrast and LG fits long static-work sessions
Quick verdict
Go with the AW2725DF for QD-OLED contrast and 360Hz over DisplayPort. For a 240Hz IPS setup that sees heavy static desktop work, the LG 27GR83Q is the fit.
Before you buy
Why, and what it costs you
Detail should be compared at the actual screen size
AW2725DF comes to about 110 pixels per inch, against 108.8 for 27GR83Q-B. The pixel densities are close enough that layout and connection needs do more to separate them.
Where this comes from
Pixels per inch = √(width² + height²) / diagonal. Calculated with 2560 × 1440 at 26.7 inches and 2560 × 1440 at 27 inches. Approximate, because the diagonals are published nominal values.

What this page compares
QD-OLED contrast and 360Hz over DisplayPort point to the AW2725DF. The LG 27GR83Q suits a 240Hz IPS setup used heavily for static desktop work.

Which one fits
Pick the situations that sound like you
Run high-frame-rate games over DisplayPort
Over DisplayPort, AW2725DF reaches its 360 Hz ceiling. Its documented HDMI ceiling is 144 Hz, which means an HDMI-only setup cannot use the 360 Hz headline.

Leave static work windows open for hours on end
The organic-pixel wear concern tied to QD-OLED does not apply to LG's IPS panel. Fixed toolbars and long static sessions are therefore a relevant ownership consideration.

Value OLED black levels
QD-OLED is what AW2725DF uses, and 27GR83Q uses IPS. Panel technology is the distinction that matters for OLED black-level behavior.

In practice
Differences you will notice
Detail should be compared at the actual screen size
AW2725DF comes to about 110 pixels per inch, against 108.8 for 27GR83Q-B. The pixel densities are close enough that layout and connection needs do more to separate them.
How we worked this out
Pixels per inch = √(width² + height²) / diagonal. Calculated with 2560 × 1440 at 26.7 inches and 2560 × 1440 at 27 inches. Approximate, because the diagonals are published nominal values.
Keep native detail apart from game speed
Per frame, AW2725DF draws 3.7 million native pixels, and 27GR83Q-B draws 3.7 million as well. Refresh ceilings are 360Hz and 240Hz respectively.
How we worked this out
Native pixels = width × height. Refresh interval =1000 / Hz, giving 2.8 and 4.2 ms. They are calculations of signal and cadence, not measurements of frame rates, input lag or pixel response.
The refresh argument can flip on an HDMI-only connection
The documented HDMI ceiling of AW2725DF is 144Hz, which is below the LG 240Hz panel ceiling. The exact LG input mode for the source should be confirmed as well.
How we worked this out
Alienware record: HDMI 144Hz, DisplayPort 360Hz. LG maximum 240Hz. Check the port-specific timings at both ends.
Option A
Alienware, AW2725DF
27 360Hz QD-OLED Gaming Monitor
At the heart of a competitive gaming desk, the AW2725DF has a 360Hz QHD OLED screen. Check its real input limit, because the HDMI version printed on the box does not tell you that.
- Best for
- Competitive PC gaming over DisplayPort
Facts we checked
- QD-OLED panel, 26.7-inch, 2560 by 1440

Option B
LG, 27GR83Q-B
UltraGear 27-inch QHD 240Hz
High-frame-rate games get more headroom on this 240Hz IPS monitor, which keeps the familiar 27-inch QHD layout. Because it has HDMI 2.1, compare the input specification with your graphics card.

Trade-offs
What each pick costs you
With Alienware 27 360Hz QD-OLED Gaming Monitor
- Video input isn't what the USB-C port is for. It handles downstream peripherals and charging.
With LG UltraGear 27-inch QHD 240Hz
- The USB ports are for peripherals and do not carry USB-C video or laptop charging.
Decision guide
How to decide
The AW2725DF is for QD-OLED contrast and 360Hz over DisplayPort. The LG 27GR83Q is for a 240Hz IPS setup used heavily for static desktop work.
The advertised refresh rate can be limited by the input
The AW2725DF reaches 360Hz over DisplayPort, but its documented HDMI ceiling is 144Hz. Don't buy an HDMI-only setup on the strength of the 360Hz headline.
Owning an OLED calls for a different routine
Panel-care precautions are warranted for static toolbars and fixed desktop elements. IPS avoids the same organic-pixel wear concern, though it gives up OLED black-level behavior.
The QHD pixel workload doesn't change
2560 by 1440 is used by both. What the Alienware asks of the PC is more frames and not more pixels per frame, so CPU and game limits can become relevant.
What this page can’t tell you
- These pixel density and refresh interval figures are calculated from published specifications and do not come from a measured visual-quality or latency test.
- The USB-C power figure is the highest level that can be negotiated. It does not guarantee full-speed charging for every laptop.
