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

[albertoalgarra]

Hi all,

my laptop (Lenovo x260) has a Intel (R) HD Graphics 520 ... I bought a external monitor which has a 2560*1440 resolution (AOC Q3279WG5B),

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

Could you help me too?

Thanks a lot in advance!

Hello albertoalgarra,  

Thank you for posting on the Intel® communities. I am sorry to know that you are having issues with your Intel® HD Graphics 520.   

In order to better assist you, please provide the following:  

1. Are you using a straight connection or are you using adapters?

2. Have you tried with a Display Port?

3. The laptop manufacturer can limit, block, or add features to their system, try to get in contact with Lenovo to confirm that the laptop ports can display this resolution.

Bear in mind that using 2560x1440 at higher refresh rates (per example 75Hz or more) usually requires a pixel clock higher than 304.25Mhz. The Intel Integrated Graphics controllers can support this requirement on HDMI 2.0 or DP 1.2, however, on HDMI 1.4 it would be limited to a pixel clock 297MHz.

Hi DeividA_Intel
Thanks for your answer. I'm going to answer your questions:
1. Are you using a straight connection or are you using adapters?
Cable HDMI directly and to DP with HDMI adapter.
2. Have you tried with a Display Port?
Yes, but with adapter.
3. The laptop manufacturer can limit, block, or add features to their system, try to get in contact with Lenovo to confirm that the laptop ports can display this resolution.
SO doesn't recognise 2K resolution when it uses Intel driver. However, SO recognises 2K resolution when it uses default Windows driver but it only plays AOC Monitor.

Hello albertoalgarra, 

Thanks for your response. In this I would like to consider the following:

1. We do not recommend using adapters since we cannot confirm that they will work properly. The best way to have better results and performance is using a straight connection.

2. Bear in mind that for this resolution to work you need to use HDMI 2.0 or Display Port 1.2 and a straight connection, no adapters.

3. Make sure that your HDMI cable is 2.0 in case the laptop does not have a display port. Also, make sure with Lenovo that the HDMI port is 2.0 as well.

4. As mentioned before, the manufacturer can add, block, and limit the features of their system as needed. Try to use the drivers from Lenovo since those are customized for your laptop.

I also recommend you check with Lenovo to confirm if there is any kind of limitation with external displays.

I have changed the cable and my lenovo x260 is recognizing the correct resolution of the monitor.

Thanks for your solution.
