Windows 10: Pixelation on one screen of a multi-monitor setup after updating graphics drivers

I'm using 2 monitors and after updating my graphics drivers my ED322Q monitor with Hardware ID MONITOR\ACR053E, is blurry and pixelated. I found this https://answers.microsoft.com/en-us/windows/forum/windows_10-hardware/pixelation-on-one-screen-of-a-multi-monitor-setup/c7c9aeec-0eef-41a0-86ca-8a9f7e334da2 and it was kinda close. Exact same monitor and no apparent drivers to download from the manufacturers website. Is not pixelated when I downgrade graphics drivers.

Second monitor appears pixelated sometimes


Before we get started, here might be some setup information that may be worth noting. My primary monitor is a 1080p, 1920 x 1080 (native) using an HDMI to DVI. My secondary monitor is a SONY TV 1360 x 768 (native) using an HDMI. Both are connected to my graphics card and not the motherboard. I have always had this setup but I have not always had this issue.

Preforming the following actions may cause my second monitor to appear pixelated.

• Getting a web browser out of maximized mode by click dragging the window or using the restore button
• Using full screen on the secondary monitor
• Dragging a window into the second monitor, sometimes

In order to temporarily solve this issue I must apply a change to any display using the Nvidia Control Panel. Using the Windows display settings to apply a change does not always fix the issue. Also note that after the second monitor goes pixelated, my computer does not detect a change in any display's resolution settings.

So far I have tried the following fixes to no avail

• Keeping display drivers up to date
• Using a DDU to wipe display drivers clean and start anew
• Using the Hardware and Devices troubleshooter

I have tried to use capture software to screenshot the pixelation but it can not see it. I have to use a camera to show what it looks like instead.

Capture software is not capable of detecting the pixelation so I have recreated what it looks like on screen. Use this as reverence if the pictures look bad.

Double Monitor Setup is not connecting

Hi Yuri,

To setup dual monitors, I suggest you to press Windows + P keys
and select Extend or the required option and check for status. If you are still unable to setup dual monitor, suggest you to update the Display Adapter driver by following the steps provided below and check for status.

• Press Windows key + X and select Device Manager.
• Expand Display Adapters.
• Right click on the driver and select Update Driver Software.
• Follow the on-screen prompts to update the driver.

Hope this helps. Keep us posted on the status for further assistance.

 

Pixelation on one screen of a multi-monitor setup after windows 10 update version 1709

Hi James,

Although you have already verified that all drivers are up-to-date, there is still a possibility that the issue is due to incompatibility. At this point in time, we we suggest that you run the monitor drivers in compatibility mode. You may refer to the steps
found in this forum article by Andre Da Costa on how to do so. Scroll
through the article and you will find the steps under the Using Compatibility Mode to Resolve Driver problems
section.

In addition, it will help if you can take note of the monitor driver's hardware ID in the Windows 10 version where it works. Here's how to locate the hardware ID:

• Open Device Manager.
• Expand Monitors, right-click on your monitor driver, and then click
  Properties.
• Go to the Details tab.
• Click the drop-down menu, and then select Hardware Ids.
• Copy the Value.

Your reply is most important for us to assist you accordingly.
