ASUS VG27AQ3A vs PA278QV: Match the Input Mode and Supplied Stand

Choose VG27AQ3A for QHD above 75 Hz with a capable source: up to 144 Hz over HDMI or 180 Hz over DisplayPort, accepting fixed stand height. Choose PA278QV for supplied height and portrait adjustment, accepting its 75 Hz ceiling. Both keep the same 27-inch QHD format.

The buying question

Do you need QHD input rates above 75 Hz, or height and portrait adjustment on the supplied stand?

VG27AQ3A retains QHD at higher input rates but has fixed stand height; PA278QV supplies height and pivot adjustment with a 75 Hz ceiling.

Quick verdict

Choose ASUS TUF Gaming VG27AQ3A if

  • Your required QHD input mode is above 75 Hz and your output, cable and monitor input support it.
  • You can use fixed stand height or have separately verified a compatible mounting solution.

Choose ASUS ProArt PA278QV if

  • You need to raise the screen or use portrait without replacing the supplied stand.
  • A refresh ceiling of 75 Hz meets your needs.

When to skip: You need both native QHD above 75 Hz and height adjustment on the supplied stand.
When the recommendation changes
  • An HDMI-only connection rules out VG27AQ3A’s QHD 180 Hz mode, but retains its listed 100/120/144 Hz modes.
  • A separately verified compatible mount can change the positioning decision.
  • Requiring both QHD above 75 Hz and built-in height adjustment rules out both.

The differences that matter

Native Qhd Input Modes

ASUS TUF Gaming VG27AQ3A

27-inch 2560 × 1440. At native resolution, HDMI supports 100/120/144 Hz; DisplayPort also supports 165/170/180 Hz.[1, 3]

ASUS ProArt PA278QV

27-inch 2560 × 1440 with a listed maximum of 75 Hz. Its manual includes a 74.924 Hz QHD timing without a per-port label.[2, 4]

What this changes: For QHD above 75 Hz, choose VG27AQ3A after checking the complete source connection. HDMI is sufficient for its listed QHD 100/120/144 Hz modes; a 180 Hz requirement needs DisplayPort. These are supported inputs, not measured motion quality.[1, 3, 2, 4]

The better fit depends on your priorities

Supplied Stand Positioning

ASUS TUF Gaming VG27AQ3A

Tilt and swivel, but explicitly no height adjustment or pivot.[1, 3]

ASUS ProArt PA278QV

150 mm height adjustment and 90-degree pivot in either direction, plus tilt and swivel.[2]

What this changes: Choose PA278QV when raising the screen or rotating it to portrait must be possible with the supplied stand. If native QHD above 75 Hz and supplied height adjustment are both mandatory, neither satisfies the combination.[1, 3, 2]

The better fit depends on your priorities

Best for your routine

A QHD 120/144 Hz desktop with HDMI output

Best fit: ASUS TUF Gaming VG27AQ3A

Based on listed features, not comparative testing.

VG27AQ3A supports these native-resolution HDMI modes without switching to Full HD. Accept its fixed-height stand and verify the source can supply the mode.

A QHD desk requiring adjustable screen height or portrait use

Best fit: ASUS ProArt PA278QV

Based on listed features, not comparative testing.

PA278QV supplies those adjustments. Its compromise is the lower input-rate ceiling.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Compare complete setups: any separately purchased mount or video cable belongs in your budget. Pay extra only for the input mode or stand adjustment you actually need.

There is insufficient verified price history for a buy-now or wait recommendation.

Limitations

  • No hands-on or comparable controlled testing establishes a gaming, motion, color, HDR, eye-comfort or reliability winner.
  • PA278QV’s generic QHD timing table is not a guarantee of that mode on every input, computer, dock or adapter. Check your intended connection.
  • Included cables and the selected retail package are not guaranteed; confirm the exact VG27AQ3A or PA278QV model and box contents.

Questions shoppers ask

If I already own a monitor arm, does PA278QV still solve the main problem?

A separately verified compatible arm can make supplied-stand adjustment less important. Then choose by the input mode your computer can deliver: replacing a stand does not raise PA278QV’s refresh ceiling.

What should I check before paying for the 180 Hz option?

VG27AQ3A’s QHD 180 Hz mode uses DisplayPort, not HDMI. Verify the computer output and every cable, dock or adapter in the path supports that mode; also confirm what is actually included in the offer.

Methodology and sources

Checked native-resolution input timings separately from the physical adjustments of the supplied stands.
