The monitor's brightness and volume cannot be controlled directly via the Mac keyboard. Operation is primarily via a 5-way joystick and six buttons on the monitor itself, which can be used to adjust settings such as brightness and volume.
You can connect a USB-C to LAN adapter to the monitor's USB-C port, but the monitor itself will not pass the LAN signal to your MacBook Air M4 if you connect it to the MacBook via Thunderbolt 4 (USB-C). The USB-C ports on the monitor are primarily used as a hub for peripheral devices and for power supply, not as a network pass-through. For a LAN connection, you must connect the adapter directly to the MacBook.
You can connect the monitor to your MacBook Air M4 via USB-C to use 5K. To do this, you need a USB-C cable that supports DisplayPort 1.4 and at least 90W Power Delivery. A high-quality Thunderbolt 4 or USB 4 cable fulfils these requirements and ensures full 5K resolution without losses.
I was able to solve my monitor wake-up problems (up to 30sec to picture) by disabling auto detect on the monitor and setting USB-C as signal input in my example
Yes, you can connect your 2018 MacBook Pro with four Thunderbolt ports to the ProArt PA279CV monitor using a USB-C connection. However, you may encounter compatibility issues with macOS, especially if you haven't updated your operating system or monitor firmware. Make sure to update macOS to a version later than 12.3.1 or download the monitor firmware update to resolve any connection issues.
The ASUS ProArt PA278QV is generally compatible with a Mac Mini as it has HDMI and DisplayPort suitable for connection to a Mac Mini. However, there are reports of problems with the audio output via the monitor, which may be due to the configuration or the cables used.
Our supplier is currently unable to deliver, therefore our offer is without delivery date.
Due to different suppliers and delivery conditions, there may be price differences compared to other suppliers, especially in international comparison. We always try to offer prices in line with the market, but this is not possible for all products.
Are you trying daisy chaining? In other words, connecting the monitor to another one? Unfortunately, this is only possible with the PA279 CRV, not with the CV.
Try connecting the Macbook directly with the USB-C cable (USB-C on the Macbook to USB-C on the screen) and not via HDMI and still with a Macbook adapter. There are problems here from time to time. Then connect the external HDD or SSD via USB-A to the monitor or (with or without adapter) directly to the Macbook.
In my case there are no screw holes on the back, possibly covered by the plastic.

To connect the monitor to a MacBook Air M4 in 5K resolution without loss, you need a USB-C cable that supports Thunderbolt 3 or 4, as only Thunderbolt can transfer the full 5K resolution via USB-C without loss. A normal USB-C cable without Thunderbolt is not sufficient for 5K. The monitor offers USB-C connections with 90 watts of charging power and USB hub functionality, which enables a direct connection with a suitable Thunderbolt USB-C cable.
A suitable docking station must support Thunderbolt 3 or 4 to transfer 5K at 60 Hz. Normal USB-C docks without Thunderbolt cannot guarantee the full 5K resolution.
The monitor has an integrated USB hub, but does not have its own network connection (LAN). You can therefore not connect a network cable directly to the monitor to use it for the MacBook Air M4. For network connections, you must connect the MacBook Air directly or via a separate docking station with a LAN connection.
To summarise:
- Use a Thunderbolt 3/4 USB-C cable for 5K at 60 Hz without loss.
- A docking station must support Thunderbolt 3/4 to ensure 5K.
- Direct LAN connection on the monitor is not available, network cable on the monitor does not work as a network bridge for the MacBook Air.
To connect the monitor to your MacBook Air M4 and utilise the full 5K resolution (5120 x 2880 pixels) without losses, you should use a USB-C cable that supports DisplayPort Alternate Mode (DP Alt Mode) and at least USB 3.2 Gen 2. The cable must be designed for 5K/60 Hz so that the signal is transmitted without loss. A standard USB-C charging cable is usually not sufficient for this, as it often only transmits power and data, but not a high-resolution video signal.
The monitor has a USB-C port that allows you to transfer image, power (up to 90 W) and USB data (for the integrated hub) with just one cable. Make sure that the cable offers the necessary bandwidth for 5K/60 Hz - if in doubt, a high-quality, certified Thunderbolt or DisplayPort cable will help.
A suitable docking station is not absolutely necessary, as the monitor itself acts as a hub and has USB-A and another USB-C port. If you still want to use a docking station, it must explicitly support 5K/60 Hz via USB-C with DP Alt Mode.
To summarise: Use a high-quality USB-C cable with DP Alt Mode and sufficient bandwidth for 5K/60 Hz, then you will get the full picture without losses - everything else (power, USB hub) runs directly via the monitor. If you are unsure, take a look at the cable specifications or contact the manufacturer's support.
To connect the monitor to a Windows Surface without losing 5K resolution, you should connect the monitor's USB-C port to the Surface's USB-C port with a USB-C cable that supports DisplayPort video and USB data. The USB-C cable must support DisplayPort Alt mode and ideally be USB 3.1 or higher to ensure full bandwidth for 5K at 60 Hz. A simple USB-C cable without these specifications may result in loss of resolution.
The monitor supports USB-C with DisplayPort video and USB data transfer as well as 96 W Power Delivery, which means that the cable should also be suitable for power supply if desired. Make sure that the cable is explicitly certified for 5K displays or DisplayPort 1.4 to transmit the full UHD+ resolution (5120 x 2880 pixels) at 60 Hz.
If your Surface does not have a native USB-C with DisplayPort Alt mode, an adapter may be necessary, but for 5K, a direct USB-C connection with DisplayPort Alt mode is the best solution. After connecting, you can adjust the projection with Windows key + P.
To summarise:
- Use USB-C cable with DisplayPort Alt mode (at least USB 3.1 Gen 2)
- Cable should support DisplayPort 1.4 for 5K at 60 Hz
- Direct connection to USB-C port of the Surface (no pure USB-A or HDMI adapter)
- Set monitor input to USB-C and configure Windows projection
These requirements ensure a lossless 5K connection between Surface and monitor.
To connect the 5K monitor to a MacBook Air M4 without loss of quality, you need a USB-C cable that supports DisplayPort Alt mode with full 5K bandwidth and is ideally Thunderbolt 3 or 4 compatible. The cable must be able to transfer high data rates (at least 40 Gbit/s) in order to display the 5120 x 2880 pixels at 60 Hz without compression.
The monitor offers USB-C connections with DisplayPort support and can transmit image signal, power supply (up to 90 W) and USB hub functionality via a USB-C cable. For a lossless 5K connection, you should use a high-quality USB-C cable that is explicitly certified for Thunderbolt 3/4 or USB-C with DisplayPort 1.4. Normal USB-C cables without these specifications cannot guarantee the full resolution and refresh rate.
To summarise:
- Use a USB-C cable with Thunderbolt 3/4 or USB-C with DisplayPort 1.4 support.
- The cable must be able to transfer high data rates (at least 40 Gbit/s).
- Make sure that the cable is certified for 5K resolution at 60 Hz.
- The MacBook Air M4 supports USB-C/Thunderbolt, so a suitable cable is required.
- The full 5K resolution cannot be achieved via HDMI or simple USB-C cables.
Yes, this monitor is very suitable as a screen extension for a MacBook. It offers a USB-C port with 90 W Power Delivery, which you can use to transfer images, sound, data and charge your MacBook at the same time. DisplayPort and HDMI are also available if you want to use other connection options. The colour accuracy (Delta E < 2) and broad coverage of the DCI-P3 and sRGB colour space make it particularly attractive for creative work. The integrated speakers and USB hub increase convenience in everyday life.
I can't get the USB hub to work. Does anyone have any ideas?
I actually have a relatively simple scenario, 1 PC via DP to the monitor, 1 laptop via HDMI or USB-C to the monitor.
Switching works. Now I wanted to connect the mouse and keyboard to the monitor, but neither is recognised. Only when I have the laptop connected to the monitor via USB-C do the mouse and keyboard work, but unfortunately only on the laptop, not on the PC. When the laptop is connected via HDMI, nothing works. What I'm unsure about is whether a USB connection to the monitor is required in addition to the DP or HDMI cable for this to work at all?
(but that would be kind of pointless, then I've almost used up the USB ports)
Unfortunately, the ASUS manual is non-existent and the online manual only lists the connections, but does not show which connections need to be made.
Thank you.
I was able to do some research and according to the user manual, you would also have to connect a USB cable via the upstream port. HDMI and DP do not forward this data in this case, so an image/audio/data connection is not possible via HDMI or DP only. This is basically the case with most monitors (all the ones I know), so that in addition to HDMI or DP you would have to connect an additional USB cable for the data connection of the USB hub. According to the manual:

I used to connect the screen to my Macbook air with a usb-c cable without any problem, and then, one time after another, without changing anything, the screen says "USB-C no signal" and I haven't been able to use the screen since... Is there a setting that could have been reset? Or is it possible that the usb-c port on the screen is already dead? (The one on my computer works fine, and I've plugged an iPad via hdmi (with a lightning-hdmi adapter) into the screen and that works too. Unfortunately I don't have a usb-c - hdmi adapter to test directly with the computer...
