The catch
ASUS TUF Gaming 27-inch QHD
Reaching 165Hz means using an overclock setting over DisplayPort.
Side by side
ASUS VG27AQ vs LG 27GP850: Beyond ASUS’s 165Hz mode, LG adds optional refresh headroom
Quick verdict
Pick the 27GP850 for its higher optional overclock ceiling. If the 165Hz mode and familiar TUF controls of the VG27AQ are enough for your QHD gaming setup, it fits.
Before you buy
Why, and what it costs you
Detail should be compared at the actual screen size
VG27AQ comes to about 108.8 pixels per inch, and 27GP850-B is 108.8 as well. 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. Values used: 2560 × 1440 at 27 inches and 2560 × 1440 at 27 inches. Using published nominal diagonals makes them approximate.

What this page compares
A higher optional overclock ceiling favors the 27GP850. The VG27AQ suits a QHD gaming setup where its 165Hz mode and familiar TUF controls are enough.

Pick the situations that sound like you
Play QHD games up to 165Hz
Through the appropriate connection, VG27AQ supports QHD gaming up to its 165 Hz ceiling. The LG has the same native resolution, so pixel workload is not changed by either.

Look for the optional 180Hz mode
Above its 165 Hz standard figure, 27GP850 offers an optional 180 Hz mode. Before relying on the overclock, confirm the required connection and mode stability.

In practice
Differences you will notice
Detail should be compared at the actual screen size
VG27AQ comes to about 108.8 pixels per inch, and 27GP850-B is 108.8 as well. 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. Values used: 2560 × 1440 at 27 inches and 2560 × 1440 at 27 inches. Using published nominal diagonals makes them approximate.
Keep native detail apart from game speed
VG27AQ draws 3.7 million native pixels per frame, and 27GP850-B draws 3.7 million too. Refresh ceilings are 165Hz and 165Hz respectively.
How we worked this out
Native pixels = width × height. Refresh interval =1000 / Hz, giving 6.1 and 6.1 ms. Signal and cadence calculations like these are not measured frame rates, input lag or pixel response.
About half a millisecond per refresh is all the optional LG mode saves
At 180Hz a refresh comes every 5.56 ms, against 6.06 ms at 165Hz.
How we worked this out
1000 / 165 - 1000 / 180 = 0.505 ms. Refresh cadence and measured input lag are different things.

|---|---|---|---|
| Native resolution | 2560 × 1440 | 2560 × 1440 | Usable logical workspace changes with operating-system scaling. |
| Panel diagonal | 27 in | 27 in | The measured active diagonal may differ slightly from a nominal screen class. |
| Maximum refresh | 165Hz / 165Hz optional mode | 165Hz / 180Hz optional mode | Look at the exact input, resolution and overclock conditions. |
| Panel technology | IPS | Nano IPS | A measured color or motion winner is not established by panel type alone. |
| Laptop power | No USB-C laptop charging | No USB-C laptop charging | For the desired delivery, the host, cable and negotiated power profile all have to support it. |
| Chassis width | 620 mm | Check exact drawing | Leave additional room for cables, arms and neighboring equipment. |
| Stand depth | 211 mm | Check exact drawing | More desk depth can be taken by the included stand than by the display cabinet. |
Trade-offs
What each pick costs you

Decision guide
How to decide
The 27GP850 is for its higher optional overclock ceiling. The VG27AQ is for a QHD gaming setup where its 165Hz mode and familiar TUF controls are enough.
Normal use is a close call
27-inch QHD IPS-family monitors, both of them. Native pixel workload and approximate density are equal, so neither delivers a resolution upgrade.
The right input and settings are needed to overclock
An optional 180Hz mode comes on top of LG's listed 165Hz. ASUS lists up to 165Hz, with a lower HDMI limit. Confirm the connection and stability at the timing you select.
Don't let a small refresh gap dominate comfort
Going from 165 to 180Hz shifts the theoretical refresh interval by about half a millisecond. Stand fit, motion tuning and the final price can matter more.
What this page can’t tell you
- Calculated from published specifications, pixel density and refresh intervals say nothing measured about visual quality or latency.
- Think of the USB-C power number as a ceiling reached by negotiation. Full-speed charging is not promised for every laptop.
