No correct resolution for my 34' curved screen from PC Laptop

[LoloDu33]

Hello everyone,

I just bought a laptop (HP - 17-cn3002nf) with an integrated Intel Iris Xe Graphics graphics card.

I plug in my 34' xiaomi screen and horror, the resolution does not change. So everything is distorted.

It is impossible to go beyond 1920x1080.

HP service tells me that you have to take a laptop with a graphics card that goes beyond 3440x1440.

But what I do not understand is that my old laptop, also with an integrated graphics card (Intel UHD Graphics 620) that does not go beyond 1600x900, when I plug in my external screen, the resolution automatically sets to 3440x1440.

Is this normal?

What is it that I do not understand?

or is it a driver problem?

Thank you for your help

Have a nice day

Hi @LoloDu33 ,

Welcome to The HP Support Community.  

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

I understand you're encountering an issue where your external monitor's resolution is limited to 1920x1080 when connected to your new HP 17.3" laptop (HP 17-c3000), which has an Intel Iris Xe Graphics card. Given that you were able to achieve a higher resolution (3440x1440) on your old laptop with Intel UHD Graphics 620, this situation may feel puzzling. Here's what might be going on and how to troubleshoot:
 

1. Check Graphics Driver

• Driver Update: It's possible that the Intel Iris Xe driver installed on your laptop is either outdated or misconfigured. Make sure you have the latest graphics driver directly from Intel's website, rather than relying solely on the default drivers from Windows Update.
  • You can download the latest Intel Iris Xe Graphics driver here.
  • After updating, restart the system and check the resolution options again.

2. Check Display Settings

• Go to Settings > System > Display, and under the section for your external monitor, see if 3440x1440 appears as an available option. If it doesn't, click on Advanced display settings to see more resolution options.
• Make sure the display scaling is set appropriately for the external monitor under Settings > System > Display > Scale and layout.

3. Use the Correct Output Port

• Output Port: Verify which port you're using to connect the external monitor. Different ports have different bandwidth limitations, which could affect the resolution.
  • HDMI: If you're using HDMI, make sure the port and cable support HDMI 2.0 or higher. HDMI 1.4 can be limited to 1920x1080 at 60Hz on some laptops.
  • USB-C/DisplayPort: If possible, try using a USB-C or DisplayPort connection for better support of higher resolutions like 3440x1440.

4. Check Intel Graphics Control Panel

• Right-click on the desktop and open the Intel Graphics Command Center or Intel Graphics Control Panel. Navigate to the Display settings and check if you can manually set the resolution to 3440x1440. Sometimes, the resolution options in Windows settings may be limited, but the Intel panel allows more flexibility.

5. External Monitor Settings

• Check the Monitor Settings: Make sure the external monitor itself is set to allow 3440x1440 resolution. Sometimes the monitor may default to a lower resolution, and you can manually change it in the monitor’s settings menu.

6. Cable Quality

• If you’re using an HDMI cable or adapter, ensure that the cable is high quality and supports higher bandwidths necessary for 3440x1440. A low-quality or older HDMI cable may only support 1080p resolution.

7. Check Laptop Specifications

• Internal Limitation: The issue may be due to limitations of the laptop itself. While Intel Iris Xe Graphics is technically capable of supporting resolutions beyond 1920x1080, it's important to ensure the specific model you have can handle an ultrawide resolution of 3440x1440. If the HDMI port on your laptop only supports HDMI 1.4, for example, it would cap at 1920x1080.
  You can also check HP's official specifications for your laptop model to confirm the maximum supported resolution on external displays.

Conclusion

The situation you're describing seems likely to be a driver or port limitation, given that your previous laptop worked fine with the same external monitor. Try updating the drivers, verifying the port type, and experimenting with the Intel Graphics Control Panel. If none of these steps resolve the issue, it's possible that the laptop's hardware, like the HDMI port

Bonjour,

Merci beaucoup pour votre message.
J'ai déjà fait tout cela, et cela n'a pas fonctionné.

Helas, quand j'ai téléphoné au services support HP, ils n'ont pas été sympa. Ils m'ont dit que j'avais acheté le mauvais ordinateur, qu'on ne pouvait pas branché cet écran.
ils ont dit qu'ils fallait un ordinateur qui a une carte graphique qui puisse accepter cette résolution. Ils m'ont proposé un PC de gamer.

Bref, le PC retourne aujourd'hui chez HP. Je suis très en colère

Je vous remercie de votre réponse, car techniquement c'est très logique.

Bonne journée à vous
