Main trade-off
Alienware 27 360Hz QD-OLED Gaming Monitor
Dell specifies 360Hz through DisplayPort but only 144Hz through HDMI.
Head-to-head
Choose AW2725DF for QD-OLED contrast and 360Hz over DisplayPort. LG 27GR83Q suits a 240Hz IPS setup used heavily for static desktop work.
Before you choose
AW2725DF works out to about 110 pixels per inch, versus 108.8 for 27GR83Q-B. Their pixel densities are close enough that layout and connection needs are stronger separators.
What this is based on
Pixels per inch = √(width² + height²) / diagonal. Inputs are 2560 × 1440 at 26.7 inches and 2560 × 1440 at 27 inches. Published nominal diagonals make these approximate.
Main trade-off
Dell specifies 360Hz through DisplayPort but only 144Hz through HDMI.
Main trade-off
A 240Hz setting does not make games render at 240 frames per second.


Choose AW2725DF for QD-OLED contrast and 360Hz over DisplayPort. LG 27GR83Q suits a 240Hz IPS setup used heavily for static desktop work.
The input can limit the advertised refresh rate
Winner by situation
AW2725DF reaches its 360 Hz ceiling over DisplayPort. Its documented HDMI ceiling is 144 Hz, so an HDMI-only setup cannot use the 360 Hz headline.
LG's IPS panel avoids the same organic-pixel wear concern associated with QD-OLED. Fixed toolbars and long static sessions are therefore a relevant ownership consideration.
AW2725DF uses QD-OLED, while 27GR83Q uses IPS. The panel technology is the relevant distinction for OLED black-level behavior.
27GR83Q pairs an IPS panel with a 240 Hz ceiling. Check the exact supported input mode for the computer or console.
What matters in practice
AW2725DF works out to about 110 pixels per inch, versus 108.8 for 27GR83Q-B. Their pixel densities are close enough that layout and connection needs are stronger separators.
Pixels per inch = √(width² + height²) / diagonal. Inputs are 2560 × 1440 at 26.7 inches and 2560 × 1440 at 27 inches. Published nominal diagonals make these approximate.
AW2725DF draws 3.7 million native pixels per frame and 27GR83Q-B 3.7 million. Their refresh ceilings are 360Hz and 240Hz respectively.
Native pixels = width × height. Refresh interval =1000 / Hz, giving 2.8 and 4.2 ms. These are signal and cadence calculations, not measured frame rates, input lag or pixel response.
AW2725DF documented HDMI ceiling is 144Hz, below the LG 240Hz panel ceiling. Confirm the exact LG input mode for the source as well.
Alienware record: HDMI 144Hz, DisplayPort 360Hz. LG maximum 240Hz. Port-specific timings must be checked on both ends.

Alienware, AW2725DF
The AW2725DF puts a 360Hz QHD OLED screen at the center of a competitive gaming desk. Its real input limit matters more than the HDMI version printed on the box.

LG, 27GR83Q-B
A 240Hz IPS monitor keeps the familiar 27-inch QHD layout while giving high-frame-rate games more room to run. HDMI 2.1 makes the input specification worth checking against your graphics card.
Meaningful differences
| What changes | Alienware 27 360Hz QD-OLED Gaming Monitor | LG UltraGear 27-inch QHD 240Hz | Why it matters |
|---|---|---|---|
| Native resolution | 2560 × 1440 | 2560 × 1440 | Operating-system scaling changes usable logical workspace. |
| Panel diagonal | 26.7 in | 27 in | A nominal screen class may differ slightly from the measured active diagonal. |
| Maximum refresh | 360Hz | 240Hz | Check the exact input, resolution and overclock conditions. |
| Panel technology | QD-OLED | IPS | Panel type alone does not establish a measured color or motion winner. |
| Laptop power | No USB-C laptop charging | No USB-C laptop charging | Host, cable and negotiated power profile must support the desired delivery. |
| Chassis width | Check exact drawing | Check exact drawing | Allow additional room for cables, arms and neighboring equipment. |
| Stand depth | Check exact drawing | Check exact drawing | The included stand can take more desk depth than the display cabinet. |
What you give up
What matters in practice
AW2725DF reaches 360Hz over DisplayPort but its documented HDMI ceiling is 144Hz. A HDMI-only setup should not be purchased around the 360Hz headline.
Static toolbars and fixed desktop elements deserve panel-care precautions. IPS avoids the same organic-pixel wear concern, while giving up OLED black-level behavior.
Both use 2560 by 1440. The Alienware asks the PC for more frames rather than more pixels per frame, so CPU and game limits can become relevant.
