Head-to-head
ASUS VG27AQ vs LG 27GP850: LG adds optional refresh headroom beyond ASUS’s 165Hz mode
The short answer
Choose 27GP850 for its higher optional overclock ceiling. VG27AQ suits a QHD gaming setup where its 165Hz mode and familiar TUF controls are enough.
Before you choose
The reasoning and the trade-offs
Compare detail at the actual screen size
VG27AQ works out to about 108.8 pixels per inch, versus 108.8 for 27GP850-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
Use QHD gaming within 165Hz
VG27AQ supports QHD gaming up to its 165 Hz ceiling through the appropriate connection. The LG has the same native resolution, so neither changes pixel workload.
- ASUS TUF Gaming 27-inch QHD
- Better fit
- LG UltraGear 27-inch Nano IPS
- Depends
Want the optional 180Hz mode
27GP850 offers an optional 180 Hz mode above its 165 Hz standard figure. Confirm the required connection and mode stability before relying on the overclock.
- ASUS TUF Gaming 27-inch QHD
- Not suitable
- LG UltraGear 27-inch Nano IPS
- Better fit
Prefer the TUF stand and controls
VG27AQ provides the TUF stand and control arrangement, with a listed 620 mm chassis width and 211 mm stand depth. Check the full position and adjustment range for the desk.

Prefer the Nano IPS panel package
27GP850 uses the Nano IPS panel package. Its optional 180 Hz mode is a separate choice from its native 2560 × 1440 pixel count.

What matters in practice
The differences that matter
Compare detail at the actual screen size
VG27AQ works out to about 108.8 pixels per inch, versus 108.8 for 27GP850-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
VG27AQ draws 3.7 million native pixels per frame and 27GP850-B 3.7 million. Their refresh ceilings are 165Hz and 165Hz respectively.
How we reached this conclusion
Native pixels = width × height. Refresh interval =1000 / Hz, giving 6.1 and 6.1 ms. These are signal and cadence calculations, not measured frame rates, input lag or pixel response.
The optional LG mode saves only about half a millisecond per refresh
180Hz refreshes every 5.56 ms versus 6.06 ms at 165Hz.
How we reached this conclusion
1000 / 165 - 1000 / 180 = 0.505 ms. Refresh cadence is not measured input lag.
Choice A
ASUS, VG27AQ
TUF Gaming 27-inch QHD
A 27-inch QHD IPS screen with up to 165Hz covers familiar PC gaming needs. The flexible stand makes more practical difference than chasing a few extra hertz on a closely related model.

Meaningful differences
What changes the fit
| What changes | ASUS TUF Gaming 27-inch QHD | LG UltraGear 27-inch Nano IPS | 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 | 165Hz / 165Hz optional mode | 165Hz / 180Hz optional mode | Check the exact input, resolution and overclock conditions. |
| Panel technology | IPS | Nano 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 | 620 mm | Check exact drawing | Allow additional room for cables, arms and neighboring equipment. |
| Stand depth | 211 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
- There is no USB hub, USB-C video or laptop charging.
If you choose LG UltraGear 27-inch Nano IPS
- There is no one-cable USB-C laptop connection.
What matters in practice
How to make the call
The normal comparison is close
Both are 27-inch QHD IPS-family monitors. Their native pixel workload and approximate density are equal, so neither delivers a resolution upgrade.
Overclocking needs the right input and settings
LG lists 165Hz with an optional 180Hz mode. ASUS lists up to 165Hz with a lower HDMI limit. Confirm the connection and stability at the selected timing.
A small refresh difference should not dominate comfort
The jump from 165 to 180Hz changes the theoretical refresh interval by about half a millisecond. Stand fit, motion tuning and the final price can matter more.
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.
