Scope

Intended Audience: All Users

Wallpaper is the image that fills the background of the phone idle screen. Some users choose one of the default backgrounds provided by the IP phone system. But some users prefer to make customized wallpaper from personal pictures. For using customized wallpaper, you need to upload the customized wallpaper and override the configuration of your phone in the PBX.

Requirements

Office Manager access to the Manager Portal

Before You Begin

Identify Your Phone Model

The instructions and overrides depend on the exact phone model.

Common supported models include:

VVX 300 / 310 / 311
VVX 400 / 410 / 411
VVX 500 / 501
VVX 600 / 601
SoundPoint IP 450 / 550 / 650 / 670

How to Find Your Model

You can usually find the model:

printed on the front bezel
on the label underneath the phone
under Settings > Status > Platform

Using the wrong model override is one of the most common causes of wallpaper issues.

Host Your Image

For custom wallpapers, the image must be hosted on a publicly accessible web server.

This Means:

The phone must be able to reach the image URL directly
The URL must not require login
Dropbox and Google Drive links usually do not work reliably
Direct HTTPS image URLs are strongly recommended

Example: https://yourdomain.com/images/company-wallpaper.png

Do not use:

Password-protected URLs
Temporary sharing links
Local file paths
Images uploaded only inside the PBX
If the image does not open directly in a browser, the phone usually cannot use it.

Background Sizes

Using the correct image size and file format is important. The images should match the screen resolution of the device to prevent stretching, cropping, and provisioning issues. Large images may fail to load or may display incorrectly.

Recommended Image Dimensions

Model	Recommended Resolution	Recommended Format
VVX 300 / 310 / 311	208 x 104 px	PNG
VVX 400 / 410 / 411	320 x 160 px	PNG
VVX 500 / 501	480 x 272 px	PNG
VVX 600 / 601	640 x 480 px	PNG
SoundPoint IP 450	320 x 160 px	BMP (4BPP)
SoundPoint IP 550 / 650	320 x 160 px	BMP (4BPP)
SoundPoint IP 670	320 x 160 px	BMP (4BPP)

VVX Phones

Recommended:

PNG (preferred)
JPG may work depending on model and firmware

Best Practice:

Use exact screen dimensions
Keep file sizes small
Avoid oversized images

SoundPoint Phones

Required:

BMP only
4BPP (16-color bitmap)

If the BMP is not created correctly, the phone will ignore it. This is the most common cause of wallpaper failures on SoundPoint phones.

VVX Background Wallpaper Overrides

Open the Manager Portal and navigate to Device > Edit > Overrides
Add the override values for your specific phone model.

VVX 300 / 310 / 311

bg.color.VVX300.selection="2,2"

bg.color.bm.2.name="https://yourdomain.com/vvx300-background.png"

VVX 400 / 410 / 411

bg.color.VVX400.selection="2,2"

bg.color.bm.2.name="https://yourdomain.com/vvx400-background.png"

VVX 500 / 501

bg.color.VVX500.selection="2,2"

bg.color.bm.2.name="https://yourdomain.com/vvx500-background.png"

VVX 600 / 601

bg.color.VVX600.selection="2,2"

bg.color.bm.2.name="https://yourdomain.com/vvx600-background.png"

SoundPoint Background Wallpaper Overrides

SoundPoint IP Phones

bg.hiRes.2.name="https://yourdomain.com/soundpoint-background.bmp"

bg.hiRes.selection="2"

For SoundPoint phones, ensure the file is a valid 4BPP BMP.

Built-In Background Selection

Some Polycom phones include built-in wallpapers that can be selected directly from the handset.

Navigate to Settings > Basic > Preferences > Background > Select Background
Choose one of the available wallpapers and save.
If your phone does not show this option, use the custom hosted wallpaper override method above.

Important

You must replace https://yourdomain.com/… with your actual image URL.
Do not copy the example URL exactly, this is one of the most common setup mistakes.

After saving overrides:

reboot the phone
or reprovision the device from the portal

The wallpaper usually does not change until the phone reprovisions.

Troubleshooting

Wallpaper Does Not Change

Check:

Correct phone model override was used
Image URL is public and opens in a browser
Phone has been rebooted
Overrides were saved to the correct device
Supported file format is being used

Image Works in Browser but Not on Phone

Usually caused by:

Redirects
Unsupported image type
Unsupported image size
SSL or certificate issues
Google Drive or Dropbox links

Use a direct image file URL instead.

Image Is Stretched or Cropped

Resize the image to match the phone’s native display resolution before uploading.

Avoid relying on automatic scaling.

Phone Returns to Default Background

This usually means:

Provisioning overwrote the setting
The override was entered incorrectly
The hosted image became unavailable

Verify the override and confirm the image URL still works.

SoundPoint Wallpaper Still Fails

Most often caused by incorrect BMP formatting.

Confirm:

BMP format
4BPP
16-color image

If these are incorrect, the phone will ignore the wallpaper.
