HP RGS – Support for ultra-wide resolution 7680x1080 (single Mosaic display)

[salome_ask]

Hi,

I am evaluating HP Z Remote Graphics Software (RGS) for a specific use case and would like to confirm whether it supports it before purchasing a license.

Here is my setup:
- Sender: an AWS EC2 instance (headless, no physical display)
- Receiver: an on-premises PC with 4 monitors configured as a single Mosaic surface via NVIDIA Mosaic, resulting in a single logical display of 7680x1080

I previously tested the same setup with HP Anyware (Teradici / PCoIP). As a reference, a first test at 3840x1080 worked perfectly. However, when I switched the Mosaic to 7680x1080 and connected to the EC2 instance, the remote desktop on the instance was capped at 4096x1080, which appears to be a hard protocol limit of PCoIP (4096x4096 pixels per display)

A 7680x1080 session is a hard requirement for my project. It is critical that the EC2 instance correctly picks up this resolution and that the protocol is able to deliver it back to the on-premises receiver at full width.
.

My questions are:
1. Does HP RGS have a maximum width limit per display at the protocol level? Specifically, can it handle a single display wider than 4096 pixels (e.g. 7680x1080)?
2. Does the RGS receiver correctly transmit the resolution of the local display to the sender, so that the EC2 instance desktop would extend to the full 7680x1080?
3. Is there any known limitation in the current version that would prevent this from working?

Additional environment info:
- Receiver OS: Windows 11
- Sender OS: Windows Server 2022 Datacenter (AWS EC2)

Thank you for your help.

Hi!

Since you are on AWS, have you tried with Amazon DCV (it´s free for AWS users). Just got a thought about this since HP do recommend to try out other solutions if RGS doesn´t fulfill your needs. If you need more info reach out to us.

Hi!

Thanks for the suggestion! I actually already tried Amazon DCV, but unfortunately it's limited to 4096x4096 resolution, which doesn't meet our needs. I even discussed this directly with the AWS teams and they confirmed this limitation.

So we're still looking for a suitable solution. Any other ideas are welcome!

Hi!

DCV can support higher resolutions, here is what you can try out;

You can get higher resolutions with the configuration below.

Linux:

sudo dcv set-config --section display --key display-encoders "['ffmpeg']"

sudo dcv set-config --section display --key codecs "['h264', 'mpeg1video', 'jpeg', 'lz4']"

Windows (powershell commands):

& "C:\Program Files\NICE\DCV\Server\bin\dcv.exe" set-config --section display --key display-encoders "['ffmpeg']"

& "C:\Program Files\NICE\DCV\Server\bin\dcv.exe" set-config --section display --key codecs "['h264', 'mpeg1video', 'jpeg', 'lz4']"

You need to restart the DCV server after this configuration.
