About the ASUS PA328
This guide covers the ASUS PA328, a 32 in. QHD monitor listed as ENERGY STAR certified. Its native resolution is 2560 × 1440 pixels (QHD 1440p), about 92 pixels per inch.
It uses a TFT LCD panel with a rated maximum luminance of 600 cd/m² (nits). It carries VESA DisplayHDR 600 certification. Listed signal and data interfaces include HDMI, DisplayPort, and USB. A USB-C port with Power Delivery can charge a connected laptop at up to 90 W while carrying video and data. Other listed equipment includes built-in speakers.
Measured on-mode power is 26.4 W, with 0.4 W in sleep and a total energy consumption (TEC) rating of 83.2 kWh per year — 5% below the ENERGY STAR limit for a display of this size and resolution. That TEC rating is lower than 15% of the 1,472 Computer Monitor models in our database.

Safety information
- Place the monitor on a stable, level surface. When using a monitor arm or wall mount, choose one rated for the monitor's weight and VESA pattern and tighten it as instructed.
- Connect the display to a properly grounded outlet with the supplied power cord. Do not use a damaged cord, and do not route it under rugs or through doorways.
- Keep the ventilation openings clear and do not place the display near radiators, heaters or in direct sunlight.
- Do not expose the display to rain, moisture or spilled liquids. If liquid gets inside, unplug it immediately and have it checked before further use.
- Unplug the display during lightning storms or when it will be unused for an extended period.
- Keep fingers clear of the hinge and height-adjustment mechanism when tilting, pivoting or raising the screen.
Setup
Position the 32 in. screen about 30–40 in. (75–100 cm) from your eyes, directly in front of you, with the top line of text at or slightly below eye level. Tilt it back 10–20° and place it at a right angle to windows to minimize glare.
- Assemble the stand
Attach the stand or monitor arm while the display is lying face-down on the protective packaging or a soft cloth. Do not press on the screen.
- Connect the video cable
USB-C is the simplest option with a laptop: one cable carries video, USB data and up to 90 W charging power. If your laptop's own charger is rated higher than 90 W, it may charge slowly under heavy load — keep its adapter handy. DisplayPort is generally the best choice for high refresh rates from a desktop graphics card. HDMI works with most laptops, desktops and game consoles.
- Set resolution and scaling
In your operating system's display settings, select the native resolution of 2560 × 1440. At about 92 pixels per inch, a scaling setting around 100% usually gives comfortably sized text; adjust to taste.
- Adjust brightness
Set brightness so a white page looks similar to a sheet of paper under your room lighting — typically 100–150 cd/m² for office work, well below this model's 600 cd/m² maximum. Lower brightness reduces both eye strain and power use.
Using your monitor
Picture modes and color
Use the on-screen display (OSD) menu to choose a picture preset. The certification record lists sRGB color space support; use the matching mode (for example sRGB for web and office work) when color accuracy matters. Avoid "dynamic" contrast modes for photo editing, as they shift brightness with screen content.
Using HDR
DisplayHDR 600 certification means the display has been tested by VESA for HDR performance, including a peak brightness of at least 600 cd/m² on HDR highlights. Turn on HDR in your operating system or game only when watching or playing HDR content; for everyday desktop work SDR mode usually looks more natural and uses less power.
Power management
The monitor enters sleep automatically when the computer stops sending a signal, dropping to 0.4 W. Set your computer to turn off the display after 5–15 minutes of inactivity so this happens during breaks. With the power button off, the monitor draws 0.34 W.
USB-C charging and docking
With a USB-C laptop connected, the monitor supplies up to 90 W through the same cable that carries the picture. Many monitors keep the USB-C port powered in sleep so the laptop continues to charge; check the OSD for a "USB charging in standby" option if you want to disable it.
Built-in speakers
Select the monitor as the audio output device in your computer's sound settings; audio is carried over HDMI, DisplayPort, or USB-C along with the picture.
Features
- USB-C Power Delivery
- Single-cable video, data and laptop charging (up to 90 W).

Care and maintenance
| When | What to do |
|---|---|
| Weekly | Dust the screen with a dry microfiber cloth using light pressure. |
| When smudged | Power the display off, then wipe with a microfiber cloth lightly dampened with water. Never spray liquid directly on the screen or use ammonia- or alcohol-based glass cleaners on anti-glare coatings. |
| Every 3 months | Vacuum or brush dust from the ventilation slots and check that cables are fully seated and not pulling on the ports. |
| Every 6 months | Check the manufacturer's support site for firmware updates, especially if you see compatibility issues with new computers or docks. |
Troubleshooting
Most display problems trace back to cables, input selection or computer settings. Work through these checks before contacting support; for model-specific messages, consult the manufacturer's manual.
| Problem | Possible cause | What to try |
|---|---|---|
| "No signal" message | Wrong input selected; loose cable; computer asleep or outputting to another screen. | Select the correct input in the OSD, reseat both cable ends, wake the computer, and press Win+P (Windows) or check Displays settings (macOS). |
| Text looks blurry or the picture does not fill the screen | Computer not sending the native resolution; scaling or overscan settings. | Set the resolution to 2560 × 1440 and adjust OS scaling instead; turn off overscan or "aspect" options in the OSD. |
| Flicker, dropouts or black screen at high refresh rates | Cable not rated for the bandwidth; adapter or dock limitation. | Use a certified DisplayPort or Ultra/Premium High Speed HDMI cable, connect directly without adapters, or lower the refresh rate to test. |
| Colors look washed out over HDMI | Limited RGB range sent by the computer or console. | Set the output to full RGB range in the graphics driver, or match the monitor's HDMI range setting. |
| Monitor does not wake from sleep | Deep-sleep option on the input; graphics driver issue. | Press a monitor button or reselect the input; disable deep sleep / auto-input in the OSD; update the graphics driver. |
| Laptop not charging over USB-C | Laptop needs more power than the port supplies; cable not rated for charging; USB-C port on laptop is data-only. | Check that the laptop accepts USB-C charging and needs no more than 90 W; use the supplied or a 5 A certified cable; try another USB-C port on the laptop. |
| No sound from the speakers | Computer outputting audio elsewhere; monitor volume muted. | Select the monitor as the audio output device and raise the monitor's volume in the OSD. |
Energy use and running costs
The ASUS PA328 has a total energy consumption (TEC) rating of 83.2 kWh per year. ENERGY STAR's TEC method assumes the screen is on about 35% of the time (roughly 8.4 hours a day) and asleep the rest. At $0.17 per kWh, it costs about $14.15 per year.
| Daily use | Energy per year | Cost per year |
|---|---|---|
| 4 hours on, 20 asleep | 41.5 kWh | $7.05 |
| 8 hours on, 16 asleep | 79.4 kWh | $13.50 |
| 12 hours on, 12 asleep | 117 kWh | $19.96 |
On-mode power is measured at the factory-default brightness. Turning brightness up, using HDR, or charging a laptop through USB-C increases consumption; using short sleep timers reduces it.
