ASUS ProArt PA278CV vs PA278QV: Which Connection Setup Fits Your Desk?
Choose the PA278CV for a compatible USB-C laptop workflow: one host cable can carry DisplayPort Alt Mode video and USB data while delivering up to 65W, and its DP output can support a tightly qualified monitor chain. Choose the PA278QV when its DVI-D or Mini DisplayPort inputs match an older source computer; its DP port is an input, not an output. Both monitors still need AC power, and a laptop's USB-C video and charging support must be checked.

The buying question
Should your setup use the PA278CV's USB-C video, data, and up-to-65W power connection, or the PA278QV's DVI-D and Mini DisplayPort inputs and separate USB hub connection?
The PA278CV combines several laptop connections and adds a DisplayPort output, while the PA278QV has more legacy video inputs but no digital video output.
Quick verdict
Choose ASUS ProArt PA278CV if
- Your computer's USB-C port supports DisplayPort Alt Mode and you want video, USB hub access, and up to 65W laptop power over the same host cable.
- You want a DisplayPort output for a daisy-chain setup and have checked the source output, resolution, OSD settings, and device limits.
Choose ASUS ProArt PA278QV if
- Your source computer has DVI-D or Mini DisplayPort output and you want one of the PA278QV's native video inputs.
- You do not need the monitor to forward video to another DisplayPort monitor, and a separate USB-B cable for the monitor's USB hub is acceptable.
When the recommendation changes
- If your laptop does not support video over USB-C, the PA278CV's one-cable display path will not work through that port.
- If a PA278CV daisy chain must run above 2560×1440 at 30Hz or include a USB-C device, ASUS's stated four-monitor condition does not apply.
- If your source computer already provides suitable independent outputs for each screen, the PA278QV's lack of DP output may not matter.
The differences that matter
Host Connection And Power Workflow
ASUS ProArt PA278CV
The PA278CV USB-C upstream port carries USB data and up to 65W power delivery. It carries video only when the source supports DisplayPort Alt Mode. A USB-C-to-A connection enables the monitor's downstream Type-A ports only; the monitor itself still connects to AC power.[1]
ASUS ProArt PA278QV
The PA278QV lists DVI-D, HDMI, DisplayPort, and Mini DisplayPort video inputs. A separate USB Type-B upstream cable enables its USB ports. Its manual lists no USB-C input, so it does not provide the PA278CV's combined USB-C video/data/power path.[4]
What this changes: The PA278CV can reduce host-side cable changes for a compatible laptop, but its 65W ceiling may not suit every laptop. The PA278QV can connect directly to DVI-D or Mini DisplayPort sources; using its USB hub adds a separate upstream cable.[1, 4]
Multi Monitor And Legacy Display Setup
ASUS ProArt PA278CV
The PA278CV has a DisplayPort daisy-chain output. ASUS documents up to four chained monitors only when the input is 2560×1440 at 30Hz and no USB-C device is connected; OSD DisplayPort Stream must be set to 1.2 and Auto Source Detection turned off. At DP 1.1, connected monitors show the same content. ASUS also specifies a DP 1.2 output from the source computer.[1, 3]
ASUS ProArt PA278QV
The PA278QV has DisplayPort, Mini DisplayPort, HDMI, and DVI-D inputs, but its manual says Digital Output: No. It cannot act as an onward DisplayPort output or a middle link in a DP daisy chain.[4]
What this changes: The CV is the fit for a compatible, bandwidth-limited DisplayPort chain. The QV is the closer direct connection for a host with DVI-D or Mini DisplayPort outputs; a chain or multi-screen plan still depends on the source computer's GPU and supported display count.[1, 3, 4, 5]
Best for your routine
One-cable laptop display, USB hub, and up-to-65W power when the computer's USB-C supports DP Alt Mode
Best fit: ASUS ProArt PA278CV
Based on listed features, not comparative testing.
The PA278CV documents video over DP Alt Mode, USB data, and up to 65W power delivery through its USB-C upstream connection. The laptop and monitor still require compatible connections and AC power for the monitor.
Connecting a source computer that has DVI-D or Mini DisplayPort but not a suitable USB-C video connection
Best fit: ASUS ProArt PA278QV
Based on listed features, not comparative testing.
The PA278QV manual lists both DVI-D and Mini DisplayPort inputs. Check the source port and required cable or adapter before ordering.
Forwarding DisplayPort video through the monitor to other displays
Best fit: ASUS ProArt PA278CV
Based on listed features, not comparative testing.
Only the PA278CV documents a DisplayPort output, and ASUS limits its four-monitor chain to specific source, resolution, device, and OSD conditions.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
A current price difference is only relevant if the buyer will use the PA278CV's compatible USB-C workflow or its constrained DP output. The PA278QV's legacy inputs may matter more when they remove the need for an adapter.
Current offer context is dynamic; there is insufficient price-history data to make a buy-now or wait timing recommendation.
Limitations
- The PA278CV's USB-C video path requires DP Alt Mode from the source, and its 65W power delivery may not meet every laptop's charging needs; its manual specifies USB-C-to-A for hub access only.
- The PA278CV's maximum four-monitor daisy-chain statement is limited to 2560×1440 at 30Hz with no USB-C device connected, DP Stream set to 1.2, and Auto Source Detection off. Confirm the source computer's DP 1.2/MST support and GPU display-count limit.
- The PA278QV accepts DisplayPort input but has no digital output; do not confuse these port directions. It adds DVI-D and Mini DisplayPort inputs.
- No controlled side-by-side display-quality testing was used, so the article does not rank color accuracy, image quality, or real-world performance.
Questions shoppers ask
Will the PA278CV charge any laptop over USB-C?
It provides up to 65W over USB-C, but the computer must also support video through USB-C DisplayPort Alt Mode for the combined video-and-data setup. Check the laptop's power requirement and USB-C specifications; ASUS's 65W maximum is not a guarantee for every laptop. The monitor still needs AC power.
Can the PA278QV daisy-chain another monitor?
The PA278QV manual lists a DisplayPort input and says Digital Output: No. It can receive a DisplayPort signal, but it has no DP output to forward the signal to a following monitor. The PA278CV has that output, subject to its manual's resolution and setup limits.
Does the PA278CV support four monitors at full QHD refresh rate through daisy-chaining?
ASUS's manual documents up to four chained monitors when the source input is 2560×1440 at 30Hz and no USB-C device is connected, with DisplayPort Stream set to 1.2 and Auto Source Detection off. It does not document four QHD displays at full refresh in that configuration.
