Maybe you can try to remove the windows update and check the system's behavior. Run the report, attach it to your answer. This is an out of spec configuration for your monitor, it supports up to 1920x1080 with HDMI, which is the resolution you are getting and the video port used (HDMI is the video port seen by the graphics adapter as per the scenario faced) You can provide the report from the link below to double check on that.There is an adapter involved on the configuration, Intel(R) does not assure the proper functioning of the system while using adapters because the functionality depends on the adapter and how well it takes the video signal from one end to the other.In this case I regret to inform you that I cannot assure the system will work with the resolution 2560x1440 because of the following: Select Intel HD Graphics XXX under "model" and hit next Go to "Graphics" folder within driver folder and select the **igdlh64.inf** file and hit open then okĨ. Click on "Have Disk" and find the extracted folder of the driver downloadedħ. Select "Let me pick from a list of device drivers on my computer"Ħ. Select "Browse my computer for driver software"ĥ. Right-click and select update driver for Intel HD GraphicsĤ. Access the device manager and look for display adapters (double-click on it, you should be able to see an Intel(R) HD Graphics adapter or Microsoft Basic Display Adapter")ģ. If you face troubles while installing the driver, please follow these steps to install it:Ģ. You can also install the latest graphics driver for the system, check links below:
If the system was working differently before the update, please check with Dell support team to find out why this happened since their monitor is working differently. If the video port used is HDMI, as per the information provided by the other user, the resolution doable is 1920x1080. I understand you would like to get 2560x1440 with your system, we can check on that for sure. Thank you for contacting the Intel Communities.
