ASUS VG27AQM5A vs LG 27GR83Q-B: Choose by Refresh Target and Desk Setup
Choose the ASUS if you have a PC and connection path that can use its advertised 300Hz ceiling; choose the LG if its 240Hz ceiling is enough and you want height and pivot adjustment plus a built-in USB connection. Check your graphics output and preferred cable before buying: the refresh rates are manufacturer specifications, not a promise that every source will drive them.

The buying question
Does the ASUS’s higher published refresh ceiling matter more to your PC setup, or does the LG’s adjustable stand and USB connection better fit your desk?
ASUS advertises a higher 300Hz ceiling, while LG lists height/pivot adjustment and USB downstream ports; both list two HDMI 2.1 inputs. ASUS documents its DP 1.4 version, but LG’s US page leaves its DP version unspecified, so verify it rather than treating that documentation gap as a product difference.
Quick verdict
Choose ASUS TUF Gaming VG27AQM5A (black) if
- You are targeting a QHD refresh mode above 240Hz and have a PC output and connection path that can use it.
Choose LG UltraGear 27GR83Q-B.AUS (black) if
- 240Hz is sufficient for your source and you want height and pivot adjustment on the included stand.
- You want two downstream USB ports connected through the monitor’s USB upstream connection.
When the recommendation changes
- Your graphics card, console, cable, selected resolution or display mode cannot use the higher refresh mode you expect.
- You plan to use a monitor arm or separate USB hub, which changes how much value you place on the included stand and USB ports.
The differences that matter
Refresh Rate And Input Mode Fit
What this changes: The ASUS offers a higher published ceiling, useful only when the source and connection can use it; this does not establish a measured performance advantage.[1, 2, 3]
Console Pc Connection And Desk Setup Fit
ASUS TUF Gaming VG27AQM5A (black)
2 HDMI 2.1, 1 DP 1.4; tilt and swivel, no height adjustment or pivot; USB-C is a firmware service port.[2]
What this changes: Both monitors list two HDMI 2.1 inputs. ASUS documents its DisplayPort as version 1.4; LG lists DisplayPort but its US product page does not state a version. If the required DP version matters, confirm that detail before choosing either monitor rather than assuming LG does not meet it. LG is the documented fit if you need built-in height/pivot adjustment or downstream USB ports; ASUS’s manual specifies no height adjustment or pivot and identifies USB-C as a firmware service port.[2, 3]
Best for your routine
A QHD PC setup that can use a refresh mode above 240Hz and prioritizes the highest published ceiling
Best fit: ASUS TUF Gaming VG27AQM5A (black)
Based on listed features, not comparative testing.
ASUS advertises 300Hz versus LG’s 240Hz; the buyer still needs a source and input path capable of the intended mode.
A desk setup that needs height/pivot adjustment from the included stand or monitor USB downstream ports
Best fit: LG UltraGear 27GR83Q-B.AUS (black)
Based on listed features, not comparative testing.
LG lists height/pivot adjustment and two USB downstream ports; ASUS specifies no height adjustment or pivot, and its USB-C port is for firmware service.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
Compare the live offers at purchase time. A higher-priced model needs to justify itself through the refresh ceiling, input layout or stand/USB features you will actually use.
The available snapshot history covers less than a month, so it is not enough to recommend buying now or waiting for a longer-term price pattern. Compare current offers when shopping.
Limitations
- No hands-on testing or controlled side-by-side measurements were conducted; this is a comparison of manufacturer-published specifications and feature fit.
- Maximum refresh modes depend on the source device, connection, resolution and selected settings. LG states that a graphics card supporting DisplayPort 1.4 or HDMI 2.1 is required for up to 240Hz.
- LG’s public product page does not specify the DisplayPort version for this model; verify the exact mode with your source before purchase.
- The ASUS manual labels its USB-C connection as a service port for monitor firmware upgrades; do not assume it carries video, charging or USB hub data.
Questions shoppers ask
Will either monitor reach its listed maximum refresh rate with my PC?
That depends on your graphics output, connection, resolution and display settings. LG specifically says a graphics card supporting DisplayPort 1.4 or HDMI 2.1 is required for up to 240Hz. ASUS lists a 48–300Hz VRR range for HDMI and DisplayPort, but check your PC and cable can use the intended mode.
Can I use the ASUS USB-C port for video or laptop charging?
The VG27AQM5A manual identifies USB-C as a service port used to connect a PC for monitor firmware upgrades. It does not establish video input, charging or USB hub functionality, so do not count it for those uses.
