Using ultrawides on hp spectre x360

[Imran_Miya]

Hi everyone. I have an hp spectre x360 15-eb0065nr from 2020. I am successfully running a samsung Odyssey G7 G75F 40 inch at native resolution of 5120x2160p at 180 Hz using one thunderbolt port. How do you think the laptop will handle a Samsung Odyssey Neo G9 57 inch? And a step further, how do you think it will handle both the G7 and the Neo G9 if they are plugged in simultaneously? What would be the refresh rates and resolution supported? I mainly use my laptop for productivity like basic MS Office and adobe PDFs. I will not do gaming on this set up. Are there any limitations in this laptop which will prevent me from using the Neo G9 at native 7680x2160p? I do understand that I cannot run the Neo G9 at 240Hz due to DP 1.4 limitation. But I should be able to at least run it at 120 Hz

Hi @Imran_Miya,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

Thank you for your detailed question. Based on the HP specifications and user guide for the HP Spectre x360 Convertible 15-eb0065nr, the system includes: 2 Thunderbolt™ / USB Type-C® ports & 1 HDMI port. This means the notebook is capable of connecting up to three external displays simultaneously (two through the Thunderbolt/USB-C ports and one through HDMI), depending on the display configurations and bandwidth requirements.

Regarding the Samsung Odyssey Neo G9 57-inch (7680 × 2160): While you've already confirmed that your current Odyssey G7 is operating at its native resolution through a Thunderbolt connection, HP does not officially validate or publish support specifications for every third-party monitor configuration, particularly ultra-high-resolution displays such as the Neo G9.

Based on the notebook specifications, the limiting factors would be the capabilities of the graphics subsystem, the Thunderbolt/DisplayPort connection, and the monitor's requirements. Because the Neo G9's native resolution is significantly higher than standard 4K displays, the actual supported refresh rate would depend on the complete hardware chain, including:

• Graphics adapter configuration 
• DisplayPort mode negotiated over Thunderbolt 
• Cable and adapter specifications 
• Monitor firmware capabilities 

For your proposed setup of running:

• Samsung Odyssey G7 (5120 × 2160) 
• Samsung Odyssey Neo G9 (7680 × 2160) 

Simultaneously, HP does not provide an officially validated configuration for these specific monitors, so we would not want to speculate on the exact refresh rates or resolutions that would be guaranteed.

What we can confirm from the HP documentation is that the notebook supports multiple external displays through its available ports:

• Up to 2 displays via the USB-C/Thunderbolt ports 
• Up to 1 display via HDMI 

If your primary use case is productivity applications such as Microsoft Office and PDF viewing rather than gaming, the system may be able to drive these displays at high resolutions, but the exact refresh rates and whether the Neo G9 will operate at its full native resolution and desired refresh rate would ultimately depend on the graphics hardware capabilities and monitor compatibility.

Could you let us know which graphics configuration your Spectre has (for example, Intel graphics only or Intel graphics with NVIDIA GeForce graphics)? If you can provide that detail, we can review the hardware specifications further and provide additional guidance.

Hello,
Thank you for the detailed response.
My Spectre x360 15-eb0065nr is configured with:
Intel Core i7-10750H
Intel UHD Graphics 630
NVIDIA GeForce GTX 1650 Ti Max-Q
I am currently running a Samsung Odyssey G7 G75F at its native resolution of 5120 × 2160 at 180 Hz through one of the Thunderbolt 3 ports while simultaneously using the notebook's internal 4K display.
To better understand the display capabilities of this platform, could you please clarify a few technical details?
Are the two Thunderbolt 3 ports connected to the Intel UHD 630 display engine, the NVIDIA GTX 1650 Ti, or both through hybrid graphics?
What DisplayPort version is exposed through the Thunderbolt 3 ports (DisplayPort 1.2, 1.4, etc.)?
Does this model support Display Stream Compression (DSC) over the Thunderbolt/DisplayPort outputs?
Are the two Thunderbolt ports independent display outputs, or do they share a common DisplayPort link from the system graphics controller?
Is there a documented maximum number of active displays supported by the platform, including the internal display?
If a monitor is operating in Picture-by-Picture mode and presents itself as two separate 3840 × 2160 displays to Windows, would the system count those as two independent external displays from the perspective of the graphics subsystem?
I understand HP may not have validated my exact monitor configuration, but any information regarding the internal display topology and graphics routing of this model would be extremely helpful.
Thank you again for your assistance.

Hi @Imran_Miya,

Thank you for the additional details and for sharing your current configuration. Based on the HP specifications and service documentation for the HP Spectre x360 15-eb0065nr, I can provide some general platform information, but I do want to note that HP does not officially validate or publish detailed display topology information for every third-party monitor configuration.
 

A few points that may help:

• The notebook is designed to support up to three active displays simultaneously:
  • The internal display
  • External display via one Thunderbolt port
  • External display via the second Thunderbolt port or HDMI

The system includes:

• Intel UHD Graphics 630
• NVIDIA GeForce GTX 1650 Ti Max-Q
• The notebook features two Thunderbolt 3 ports and one HDMI port, allowing multiple external displays to be connected.
   

Regarding your more specific questions:

• HP does not publish documentation confirming whether the Thunderbolt ports are routed exclusively through the Intel GPU, the NVIDIA GPU, or both through dynamic graphics switching.
• HP documentation also does not specifically confirm the exposed DisplayPort revision or Display Stream Compression (DSC) capabilities for this model.
• The service guide does not provide details on whether the two Thunderbolt ports have independent DisplayPort links or share a common link from the graphics controller.
   

For your Picture-by-Picture (PBP) question:

• In general, if a monitor presents itself to Windows as two separate displays, Windows and the graphics subsystem typically treat them as two independent external displays. This means a PBP configuration can consume multiple display outputs from the perspective of the operating system and graphics controller.

Since you are already successfully running the Samsung Odyssey G7 at 5120 × 2160 @ 180 Hz while also using the internal 4K panel, your current setup is operating beyond what HP officially validates and is a good indication that the display pipeline is functioning efficiently in your specific configuration.
 

If your goal is to determine whether a Samsung Odyssey Neo G9 57-inch (7680 × 2160) can operate at its native resolution and what additional displays could be connected simultaneously, I would recommend checking the capabilities reported by the graphics drivers directly (Intel Graphics Command Center and NVIDIA Control Panel), as those utilities will provide more accurate information for your exact hardware and driver combination than HP's published documentation.

Thank you for the clarification.

I understand HP does not publish detailed Thunderbolt display topology information for this model.

Since the system is documented to support up to three active displays, could you clarify whether this limitation is based on:

1. The maximum number of display pipelines supported by the platform, or
2. HP's validated configurations only?

Additionally, if a monitor is operating in Picture-by-Picture (PBP) mode and presents itself to Windows as two separate displays, would those two displays count individually toward the platform's maximum active display count?

For example, if Windows detects:

• Internal laptop display
• PBP Display A
• PBP Display B

Would that already represent three active displays from the platform's perspective?

Thank you for any additional clarification you can provide.

Hi @Imran_Miya,

For the HP Spectre x360 15-eb0065nr, the information available through HP documentation is limited to the validated display support specifications. HP documents support for up to three active displays, including the notebook display and supported external displays connected via the available video outputs.
 

Regarding your question about whether this is a hardware pipeline limit or an HP validation limit, HP does not publish the internal display pipeline architecture or graphics routing details for this model. Therefore, from an HP support standpoint, we can only reference the validated configuration and cannot officially confirm the maximum theoretical display count supported by the graphics subsystem.

For Picture-by-Picture (PBP) mode:

If a monitor presents itself to Windows as two separate displays, Windows will generally enumerate them as two independent displays. In your example:

• Internal laptop display
• PBP Display A
• PBP Display B

Windows would typically recognize that as three active displays.

However, HP has not specifically validated or documented PBP monitor configurations for this platform, so we cannot officially confirm how a particular monitor model will be counted by the graphics subsystem in every scenario.

Since these configurations depend on the interaction between the monitor firmware, graphics drivers, operating system, and hardware, the actual behavior can vary. The most accurate way to verify the active display count for your specific setup would be through Windows Display Settings and the graphics management utilities once the displays are connected.
