Intel HD Graphic 520 not working with 2560*1440 external monitor resolution

[zaga69]

Hi all,

my laptop (Surface Book) has a Intel (R) HD Graphics 520 ... I bought a external monitor which has a 2560*1440 resolution,

Despite the HD Graphics 520 has several modes with higher resolution like 2560*1600, it does not work...the eternal monitor only is allowed to use 1920*1080

I have another laptop (HP), and it has Intel (R) HD Graphics 620... In this one, the external monitor is allowed to display the scree with 2560*1440 despite the higher resolution of the Intel (R) HD Graphics is 1920*1080

Any idea?

Many thanks in advance!

Hello zaga69, 

Thank you for posting on the Intel® communities.   

Please be aware that the Intel® HD Graphics 520 can support up to 4096x2304@24Hz via HDMI and 4096x2304@60Hz via DisplayPort (DP). Meaning that as long as bandwidth and system configuration allow it, the GPU will display any resolution equal or lower than the Max Resolution supported by the processor. As you already checked with another PC, the graphics card and driver can give this resolution; the problem in this case then seems to be the limitations in your specific system and you may need to consult the system manufacturer to check the specifications.  

So we can better assist you, please provide the following: 

1. Run the Intel® System Support Utility (Intel® SSU) and attach the report generated:   

• Open the application, check the "Everything" box, and click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View".    
• Click on the menu where it says "Summary" to change to "Detailed View".    
• To save your scan, click on "Next", then "Save".    
• Use the option under the reply window to attach the report to the thread (Drag and drop here or browse files to attach).   

2. Provide the Report for Intel® Graphics Drivers, follow this link.  

3. You would like to set 2560x1440, what is the refresh rate? 

4. For the connection, provide: 

• Brand and model of the monitor. 
• What cables and ports are you using? I.e. HDMI 2.0, DP 1.4, etc.  
• Are you using an adapter or converter from your system to the monitor? If yes, please provide the brand and model.

Hi,

finally the problem was solved following your instructions,

Being precise, the root cause of the issue was the cable that I was using to convert the HDMI to Mini DisplayPort,

I bought now the right one,

Thanks
