INZONE Gaming Monitor: Frequently Asked Questions (FAQ)

What is the monitor design concept?

Considering competitive games as sports, INZONE products were designed as professional gear for game players, which fit the flexible playing style of eSports players.
In combination with PlayStation®5, there is a sense of unity in design. You can also combine the monitor with other gaming platforms, including gaming computers.

What is the INZONE Hub application?

INZONE Hub is computer software that controls INZONE monitors and headsets. It allows you to personalise experiences by customising various operations, including sound and picture settings. You can also assign the headset's specific picture mode and sound profiles to individual computer applications and games.

Operating systems: Microsoft Windows 11 OS, Windows 10 OS

Visit the INZONE Hub support page for details.

What is the KVM switch (Auto switch function)?

KVM stands for Keyboard, Video, and Mouse. You can control two computers or one computer and one gaming console with a single set of a keyboard, mouse, and headset. The device controlled by USB devices changes automatically, according to the video input source selected.

How can I clean the monitor?

Check the following:

• Gently wipe the screen or the exterior with a dry, soft cloth (e.g. an eyeglass cleaner).
• For inks from oil markers on the screen, soak a cloth in a non-soap synthetic cleanser, diluted with water to be less than 1% cleanser. Squeeze the cloth tightly to eliminate excess liquid, then wipe gently to remove the ink. Immediately afterwards, gently wipe the screen with a soft, dry cloth.
• Don't use detergent with abrasives (e.g. a cleanser).

The DisplayPort, HDMI, and USB cables are not supplied in the package.

Cables to connect the devices and the monitor are not supplied because the required cable type, version, or length depends on the customer's environment. The customer should purchase appropriate cables separately.

The supplied AC adaptor is large

To minimise desktop space, an AC adapter is selected. Its shape is optimised to reduce the heat generated by the power supply and prevent the adapter from overheating.

What can I do with the import/export option in the Device Settings of the INZONE HUB application?

You can save (export) and read (import) items to your computer only in Display Settings.
Note: Items in Device Settings and App Sync Settings cannot be exported or imported.

Unable to set Picture Adjustment.

Available settings differ depending on the Preset mode or input signals.

• When the Preset mode is set as Standard, FPS game, or Cinema: Sony provides the best setting by default, and menu items are greyed out.
• When the Preset mode is set to Game1 or Game 2: It can be adjusted with desired settings. If Eco mode is on, the menu items are greyed out.
• When the input signal is HDR: Only the Aspect ratio can be set.

When displaying both setting screens of the INZONE Hub application and the monitor, they do not synchronise.

The settings screens do not change synchronously, but the settings are correctly changed from the INZONE Hub application or the monitor. To synchronise, exit the INZONE Hub application and relaunch it, or close the setting screen of the monitor and display it again.

The screen flashes brighter or darker when changing the monitor settings on the INZONE hub application.

When you select the Sony monitor with multiple monitors connected, the monitor may flash to notify you that the flashing monitor is selected.
Note: The screen will only flash when the signal is SDR and will not flash during HDR signal.

The main menu cannot be displayed without an input signal

This is a specification of the product. Only an input selection menu will be displayed when pressing the joystick on the monitor without an input signal.

The "Auto picture mode signal was detected..." message is displayed on the monitor and cannot be turned off

When this message appears, use the joystick on the back right side of the monitor to select OK or Cancel. The message cannot be turned off using a mouse.

Note: The entire message is: "Auto picture mode signal was detected. Preset mode and Eco mode settings will be changed. Changing these settings will increase power consumption. (If Cancel, Auto picture mode will be turned off) Select using joystick".

The picture mutes and displays a "Scanning for signal" message when you change the video signal (SDM-U27M90)

This happens when the VRR (Variable Reflash Rate) signal changes from the source device (from Off to On or On to Off). Depending on the VRR signal, it may take some time to adjust the signal frequency when switching. Please wait a moment until the picture refreshes.
Note:  Disabling the VRR function on your source device minimises the mute period, but you can't enjoy the VRR function.

The USB hub function doesn't work, I can't use a mouse or keyboard that is physically connected to the monitor, or I can't control a device connected to the monitor

Set the KVM switch correctly, then select the input assigned to KVM switch 1 or KVM switch 2.
Note: For details, refer to the USB hub and Using the KVM switch (Auto switch function) sections in the Help Guide. Manuals are posted on your model support page.

I can see shaking on the monitor (for the SDM-U27M90)

This may be improved by setting Adaptive-Sync/VRR to ON.
Notes:

• Set VRR to On when using an HDMI input (only VRR is displayed on the Settings screen).
• Set Adaptive-Sync to On when using the DisplayPort or USB-C inputs (only Adaptive-Sync is displayed on the Settings screen).

Some ghosting appears when the Response time is set to Faster

Ghosting may appear during fast gameplay when the Response time is set to Faster. This is due to excessive panel overdrive, which may cause slight yet noticeable visual artefacts in the image. To avoid ghosting, change the Response time to Standard or Fast.

The monitor has a stuck pixel

The LCD panel fitted to this unit is manufactured with high-precision technology, giving a functioning pixel ratio of at least 99.99%. A very small proportion of pixels may be stuck, either always off (black), always on (red, green, or blue), or flashing. This is not a malfunction.

The monitor has some light leakage when playing games in a dark room

To reduce the blooming or halo effect, try the following setting:

• For the SDM-U27M90: Set the Local dimming to Low or Off.
• For the SDM-F27M30: Set the Dynamic contrast to Low or Off.

Note: The setting may cause the whole screen to look washed out.

The monitor software update fails

If the software update fails and the "Update failed. Check the connection and try again" error message appears on the INZONE Hub application, please check the connection in the following order: 

1. If you've connected external devices (other than a keyboard or a mouse) to the monitor or computer, disconnect them.
2. Disconnect the USB cable for the KVM switch, then reconnect the cable.
3. Disconnect the monitor's power cable and leave it disconnected for at least 1 minute, then reconnect it.

After checking the connection, restart the computer and try the software update again.

Note: The computer may be unstable (e.g. immediately after updating the Windows operating system).
