Head-to-head
ASUS VG27AQL1A vs LG 27GR83Q: LG’s 240Hz matters when the PC exceeds ASUS’s 170Hz ceiling
The short answer
Choose 27GR83Q for a 240Hz QHD gaming setup. VG27AQL1A suits a PC that spends most of its time below its 170Hz maximum and needs a flexible stand.
Before you choose
The reasoning and the trade-offs
Compare detail at the actual screen size
VG27AQL1A works out to about 108.8 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 27 inches and 2560 × 1440 at 27 inches. Published nominal diagonals make these approximate.

Winner by situation
Start with what you need it to do
Game below the 170Hz ceiling
VG27AQL1A supports up to 170 Hz through the appropriate DisplayPort setup. Its HDMI ceiling is 144 Hz, which is the relevant limit for an HDMI-only source.
- ASUS TUF Gaming 27-inch QHD 170Hz
- Better fit
- LG UltraGear 27-inch QHD 240Hz
- Depends
Display QHD games at 240 Hz
LG 27GR83Q reaches 240 Hz while ASUS stops at 170 Hz. A game delivering near 240 frames per second can use the LG's additional refresh opportunities.
- ASUS TUF Gaming 27-inch QHD 170Hz
- Not suitable
- LG UltraGear 27-inch QHD 240Hz
- Better fit
Prefer the TUF ergonomic setup
VG27AQL1A provides the TUF ergonomic setup in a 615 mm-wide body with a 215 mm stand depth. Check the actual adjustment positions against the desk and seating.
- ASUS TUF Gaming 27-inch QHD 170Hz

- LG UltraGear 27-inch QHD 240Hz
- Depends
Require a 240 Hz QHD ceiling
27GR83Q provides a 240 Hz QHD ceiling, 70 Hz higher than the ASUS maximum. This does not by itself establish complete input latency.

What matters in practice
The differences that matter
Compare detail at the actual screen size
VG27AQL1A works out to about 108.8 pixels per inch, versus 108.8 for 27GR83Q-B. Their pixel densities are close enough that layout and connection needs are stronger separators.
How we reached this conclusion
Pixels per inch = √(width² + height²) / diagonal. Inputs are 2560 × 1440 at 27 inches and 2560 × 1440 at 27 inches. Published nominal diagonals make these approximate.
Separate native detail from game speed
VG27AQL1A draws 3.7 million native pixels per frame and 27GR83Q-B 3.7 million. Their refresh ceilings are 170Hz and 240Hz respectively.
How we reached this conclusion
Native pixels = width × height. Refresh interval =1000 / Hz, giving 5.9 and 4.2 ms. These are signal and cadence calculations, not measured frame rates, input lag or pixel response.
LG raises the refresh ceiling by about 41% at unchanged QHD resolution
The 240Hz panel has 70 more refresh opportunities per second than the 170Hz ASUS maximum.
How we reached this conclusion
(240 / 170 - 1) × 100 = 41.2%. Both use 2560 × 1440 pixels. No game-frame-rate increase is promised.
Choice A
ASUS, VG27AQL1A
TUF Gaming 27-inch QHD 170Hz
The VG27AQL1A adds a USB hub and wide-gamut panel to the familiar 27-inch QHD gaming format. Its 170Hz ceiling is only a small step from 165Hz, so connections and the current offer deserve more weight.
- Best matched use
- QHD gaming with a wider color gamut and USB hub
Checked facts
- 27-inch 2560 by 1440 IPS panel with up to 170Hz refresh
- 96 percent DCI-P3 coverage
- Two USB-A downstream ports, DisplayPort and two HDMI inputs
Choice B
LG, 27GR83Q-B
UltraGear 27-inch QHD 240Hz
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.
- Best matched use
- Fast QHD games on the same screen used for work
Checked facts
- 27-inch 2560 by 1440 IPS panel at 240Hz
- HDMI 2.1 and DisplayPort inputs
- 95 percent DCI-P3 coverage and a height-adjustable pivoting stand
Meaningful differences
What changes the fit
| What changes | ASUS TUF Gaming 27-inch QHD 170Hz | LG UltraGear 27-inch QHD 240Hz | Why it matters |
|---|---|---|---|
| Native resolution | 2560 × 1440 | 2560 × 1440 | Operating-system scaling changes usable logical workspace. |
| Panel diagonal | 27 in | 27 in | A nominal screen class may differ slightly from the measured active diagonal. |
| Maximum refresh | 170Hz / 170Hz optional mode | 240Hz | Check the exact input, resolution and overclock conditions. |
| Panel technology | IPS | 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 | 615 mm | Check exact drawing | Allow additional room for cables, arms and neighboring equipment. |
| Stand depth | 215 mm | Check exact drawing | The included stand can take more desk depth than the display cabinet. |
What you give up
Every choice has a cost
If you choose ASUS TUF Gaming 27-inch QHD 170Hz
- Wide-gamut color is not automatically more accurate for ordinary sRGB content.
If you choose LG UltraGear 27-inch QHD 240Hz
- USB ports serve peripherals, not USB-C video or laptop charging.
What matters in practice
How to make the call
The LG asks for more frames, not more pixels
Both are 27-inch 2560 by 1440 IPS displays. A faster GPU or CPU helps only if the game can actually deliver the additional frames.
The ASUS headline is an overclock mode
VG27AQL1A reaches 170Hz through the appropriate DisplayPort setup. Its HDMI maximum is 144Hz, so an HDMI-only buyer should use that figure.
The meaningful interval gain is under two milliseconds
Moving from 170 to 240Hz reduces the theoretical interval from 5.88 to 4.17 ms. The complete latency also includes the game, input path and pixel response.
What this comparison cannot tell you
- Pixel density and refresh intervals are calculations from published specifications, not a measured visual-quality or latency test.
- USB-C power is a maximum negotiated ceiling. It does not promise full-speed charging for every laptop.
