The main trade-off
The LG prioritizes a much higher supported refresh ceiling over HDMI 2.1 or DisplayPort 1.4; the ASUS prioritizes USB-C display/data and up to 65W power delivery with a downstream USB hub, with a 75Hz maximum refresh rate.
Quick verdict
Both are 27-inch QHD (2560 × 1440) IPS monitors, so choose by source and cabling. The LG supports up to 240Hz with a compatible DisplayPort 1.4 or HDMI 2.1 graphics output; the ASUS tops out at 75Hz but combines USB-C DisplayPort, data, and up to 65W power delivery with its USB hub. These are documented feature-fit differences, not measured image-quality or motion-performance results.
Choose LG 27GR83Q-B.AUS 27-inch QHD 240Hz UltraGear Monitor (Black) if
- Your PC can output QHD above 75Hz and you want the LG's documented up-to-240Hz mode over supported DisplayPort 1.4 or HDMI 2.1.
- You prefer a desk connection built around HDMI or DisplayPort and do not need the monitor to provide USB-C laptop charging.
Choose ASUS ProArt Display PA278CV 27-inch QHD Monitor (Black/Silver) if
- Your laptop supports USB-C DisplayPort Alt Mode and 65W or less is enough for its charging needs.
- You want display and USB data through USB-C, with compatible USB peripherals connected to the monitor's USB-A hub.
When the recommendation changes
- If your laptop needs more than 65W, verify its power requirement before treating the ASUS as its charger.
- If your source cannot output above 75Hz, the LG's higher listed ceiling may not change your setup choice.
- If you need one display to combine high refresh above 75Hz with USB-C video and laptop charging, neither product's documented feature set establishes that combination.
The differences that matter
| Decision point | LG 27GR83Q-B.AUS 27-inch QHD 240Hz UltraGear Monitor (Black) | ASUS ProArt Display PA278CV 27-inch QHD Monitor (Black/Silver) |
|---|---|---|
| Resolution Refresh Input Workflow | The 27GR83Q-B is a QHD display with a maximum 240Hz refresh rate. LG says up to 240Hz requires a graphics card supporting DisplayPort 1.4 or HDMI 2.1.[1] | The PA278CV is QHD with a maximum refresh rate of 75Hz; ASUS lists HDMI signal vertical frequency up to 75Hz and DisplayPort up to 75Hz.[3] |
What this changes: For a source capable of more than 75 QHD frames per second, the LG offers a higher documented refresh ceiling, subject to the graphics output and connection supporting the required mode. The ASUS is the lower-ceiling option; this specification comparison does not measure motion clarity, response behavior, or gaming performance.[1, 3] The better fit depends on your priorities | ||
| Connection Power Workflow | LG's US product page lists two HDMI 2.1 inputs, DisplayPort, USB upstream, two USB downstream ports, and a four-pole headphone output. The LG US product page's interface list does not list a USB-C display input or USB-C power delivery.[1] | The PA278CV has one USB-C port with DisplayPort Alt Mode and up to 65W power delivery. ASUS says USB-C can carry DisplayPort video and data, provide power, and enable the monitor's USB-A downstream ports. Its manual specifies that the source must support DP Alt Mode for video, audio, and data over USB-C.[3, 4] |
What this changes: For a compatible laptop whose power need is within 65W, ASUS documents a single USB-C path for display, data, charging, and access to attached USB-A peripherals. LG's listed input set instead calls for an HDMI or DisplayPort video connection and a separate laptop power path; confirm the exact host ports and power needs before buying.[1, 3, 4] Best fit: ASUS ProArt Display PA278CV 27-inch QHD Monitor (Black/Silver) | ||
| Shared Qhd Resolution | 27-inch QHD IPS panel at 2560 × 1440.[1] | 27-inch IPS panel at 2560 × 1440.[3] |
What this changes: Neither product is a 4K upgrade over the other; resolution does not separate this pair. The choice turns on supported refresh/input and laptop connection needs.[1, 3] No clear winner | ||

Limitations
- No hands-on or controlled side-by-side test was performed. The comparison covers manufacturer-listed modes and connections; it does not rank image quality, response behavior, motion clarity, or color accuracy.
- LG states that reaching up to 240Hz requires a graphics card supporting DisplayPort 1.4 or HDMI 2.1. Actual output also depends on the source device and connection used.
- ASUS specifies up to 65W USB-C power delivery. Check the laptop's power requirement and USB-C DisplayPort Alt Mode support; a monitor output rating alone does not establish that it can replace every laptop charger.
- LG's US interface list names HDMI, DisplayPort, USB upstream/downstream, and headphone output, without listing USB-C. Confirm the exact product and host cabling if USB-C video or charging is essential.
Questions shoppers ask
Can the LG reach 240Hz with any PC or console?
LG says up to 240Hz requires a graphics card that supports DisplayPort 1.4 or HDMI 2.1. Match the source output and cable to the mode you want; the maximum specification is not a promise that every attached source will output 240Hz.
Will the ASUS USB-C port charge every laptop?
No universal compatibility or charging result is established. ASUS lists up to 65W and says the host must support DisplayPort Alt Mode for USB-C video, audio, and data. Check both the laptop's USB-C video support and its required charging wattage.
Do both monitors have the same resolution?
Yes. Both are 27-inch 2560 × 1440 QHD IPS monitors; the principal documented difference here is refresh/input capability and the ASUS's USB-C laptop workflow.
Methodology and sources
Compared the US manufacturer specifications and the PA278CV user guide for supported QHD refresh/input modes and the exact display, data, power, and downstream USB connections. Maximum specifications are not treated as measured real-world performance.
AI assistance organized model-specific manufacturer information and drafted this comparison. Before buying, confirm that your source device and cable support the display mode you want, that your laptop supports USB-C DisplayPort Alt Mode and needs no more than 65W if you plan to use ASUS charging, and that the current offer terms suit you.
