    <link>https://community.intel.com/t5/Graphics/UHD-620-freezing-and-lagging-Driver-bug/m-p/1205512#M89454</link>
    <description>&lt;P&gt;Hello thanks for the reply &lt;a href="https://community.intel.com/t5/user/viewprofilepage/user-id/32471"&gt;@Sebastian_M_Intel&lt;/a&gt;&amp;nbsp;.&lt;/P&gt;
&lt;P&gt;Some thing you may be missing is that my system has single channel memory, in the task manager it says "row of chips" for the memory configuration.&lt;/P&gt;
&lt;P&gt;Also my screen is a uhd (3840 x 2160) screen.&lt;/P&gt;
&lt;P&gt;As per the driver, you can manually install an unsupported driver through device manager in windows. I saw it mentioned on another thread here and I installed it for testing purposes. Although there were some issues due to the incompatability, the driver let me scroll perfectly smooth with videos on the screen.&lt;/P&gt;
&lt;P&gt;Something to note is that the scrolling issue is likely related to the D3D11 ANGLE backend.&lt;/P&gt;
&lt;P&gt;Thanks again for your help and for looking into this issue.&amp;nbsp;&lt;/P&gt;</description>

      <title>UHD 620 freezing and lagging - Driver bug</title>
      <link>https://community.intel.com/t5/Graphics/UHD-620-freezing-and-lagging-Driver-bug/m-p/1202746#M89176</link>
      <description>&lt;P&gt;I have an XPS 13 9370 with a 4k display that has a i7 8550u and uhd 620.&lt;/P&gt;
&lt;P&gt;I am getting awful graphical performance all around windows, browsing, and any application.&lt;/P&gt;
&lt;P&gt;I have tested using intel display driver from Dell (repackaged DCH driver) and the latest DCH driver from intel. Both have this issue. IMG_1999 shows an example of this.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I saw a post with a solution for an older laptop with the same problem which was to install the intel 15.45 legacy driver.&amp;nbsp;&lt;A href="https://downloadcenter.intel.com/download/29805/Intel-Graphics-Driver-for-Windows-15-45-" target="_blank"&gt;https://downloadcenter.intel.com/download/29805/Intel-Graphics-Driver-for-Windows-15-45-&lt;/A&gt;&lt;/P&gt;
&lt;P&gt;This pretty much solved the performance issue however it introduced a new issue. IMG_2003 shows this&lt;/P&gt;
&lt;P&gt;playing a video on this driver in any application would either cause it to crash or crash then recover before playing the video (see attached video) IMG_2006 shows this.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Check videos for examples&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Hello&amp;nbsp;AArya9,&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Thank&amp;nbsp;you&amp;nbsp;for&amp;nbsp;posting&amp;nbsp;on&amp;nbsp;the&amp;nbsp;Intel®&amp;nbsp;communities.&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;In addition to the report you provided, we will highly appreciate that you provide the following:&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;1. Get the&amp;nbsp;DxDiag&amp;nbsp;report and attach it to the thread:&amp;nbsp;&lt;/P&gt;
&lt;UL&gt;
&lt;LI&gt;Go&amp;nbsp;to&amp;nbsp;&lt;STRONG&gt;Start&amp;nbsp;&lt;/STRONG&gt;&amp;gt; &lt;STRONG&gt;Run&amp;nbsp;&lt;/STRONG&gt;or&amp;nbsp;&lt;STRONG&gt;Windows Key + R&lt;/STRONG&gt;.&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;On&amp;nbsp;the&amp;nbsp;Run&amp;nbsp;prompt,&amp;nbsp;type&amp;nbsp;"&lt;STRONG&gt;dxdiag&lt;/STRONG&gt;"&amp;nbsp;then&amp;nbsp;click&amp;nbsp;OK.&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;On&amp;nbsp;the&amp;nbsp;&lt;STRONG&gt;DirectX&amp;nbsp;Diagnostic&amp;nbsp;Tool&lt;/STRONG&gt;&amp;nbsp;window,&amp;nbsp;click&amp;nbsp;on&amp;nbsp;&lt;STRONG&gt;Save&amp;nbsp;All&amp;nbsp;Information&lt;/STRONG&gt;.&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;Browse&amp;nbsp;to&amp;nbsp;a folder,&amp;nbsp;type&amp;nbsp;in a&amp;nbsp;filename&amp;nbsp;then&amp;nbsp;click&amp;nbsp;&lt;STRONG&gt;Save&lt;/STRONG&gt;.&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;Use&amp;nbsp;the&amp;nbsp;option&amp;nbsp;under&amp;nbsp;the&amp;nbsp;reply&amp;nbsp;window&amp;nbsp;to&amp;nbsp;attach&amp;nbsp;the&amp;nbsp;report&amp;nbsp;to&amp;nbsp;the&amp;nbsp;thread&amp;nbsp;(&lt;STRONG&gt;Drag and&amp;nbsp;drop&amp;nbsp;here&amp;nbsp;or&amp;nbsp;browse&amp;nbsp;files&amp;nbsp;to&amp;nbsp;attach&lt;/STRONG&gt;).&amp;nbsp;Please&amp;nbsp;note&amp;nbsp;that&amp;nbsp;only&amp;nbsp;one&amp;nbsp;file can be&amp;nbsp;attached&amp;nbsp;at a time.&amp;nbsp;&lt;/LI&gt;
&lt;/UL&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;2.&amp;nbsp;We&amp;nbsp;could&amp;nbsp;not&amp;nbsp;reproduce&amp;nbsp;the&amp;nbsp;videos "&lt;STRONG&gt;IMG_2003.mov/IMG_2006.mov&lt;/STRONG&gt;", can you try to send them in a different format like .MP4? You can also use YouTube* and just share the link with us.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;3. You can check the attachments and you will see the "&lt;STRONG&gt;Graphics bug report&lt;/STRONG&gt;" attached, some of the information will be already included on the reports, but if you can fill the document and attach it to this thread will be very useful. The most important information about this report will be the "&lt;STRONG&gt;Configurations&lt;/STRONG&gt;" and "&lt;STRONG&gt;How&amp;nbsp;to repro"&amp;nbsp;&lt;/STRONG&gt;categories&lt;STRONG&gt;.&lt;/STRONG&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Regards,&amp;nbsp;&lt;/P&gt;

      <description>&lt;P&gt;Hello&amp;nbsp;AArya9,&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Thank&amp;nbsp;you&amp;nbsp;for&amp;nbsp;the&amp;nbsp;detailed&amp;nbsp;report,&amp;nbsp;please&amp;nbsp;help&amp;nbsp;us&amp;nbsp;to&amp;nbsp;confirm&amp;nbsp;the&amp;nbsp;following:&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;1. I noticed that you use Edge and Chrome for this, are both browsers up to date? You can try updating them in case they are not. Also, try using a third monitor like Firefox* just for testing.&amp;nbsp;&lt;/P&gt;&lt;UL&gt;&lt;LI&gt;Edge:&amp;nbsp;&lt;A href="https://www.microsoft.com/en-us/edge" rel="noopener noreferrer" target="_blank"&gt;https://www.microsoft.com/en-us/edge&lt;/A&gt;&amp;nbsp;&lt;/LI&gt;&lt;LI&gt;Chrome:&amp;nbsp;&lt;A href="https://www.google.com/chrome/" rel="noopener noreferrer" target="_blank"&gt;https://www.google.com/chrome/&lt;/A&gt;&amp;nbsp;&lt;/LI&gt;&lt;LI&gt;Firefox:&amp;nbsp;&lt;A href="https://www.mozilla.org/en-US/firefox/new/" rel="noopener noreferrer" target="_blank"&gt;https://www.mozilla.org/en-US/firefox/new/&lt;/A&gt;&amp;nbsp;&lt;/LI&gt;&lt;/UL&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;2. Are you connecting to the internet wired or wirelessly?&amp;nbsp;&amp;nbsp;&lt;/P&gt;&lt;P&gt;3. Instead of using the built-in display of your laptop, can you try an external monitor and check if the behavior persists?&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;/P&gt;&lt;P&gt;4. Try storing one of the videos locally, and check if a similar behavior occurs.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;B&gt;Note:&lt;/B&gt;&amp;nbsp;Links to third-party sites and references to third-party trademarks are provided for convenience and illustrative purposes only.

      <description>&lt;P&gt;The issue also occurs on Firefox.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I do not have a way to connect this laptop to an external monitor unfortunately since it only has USB C and no HDMI.&lt;/P&gt;
&lt;P&gt;I am fairly certain that this is a driver issue because on a legacy driver (non DCH), the scrolling is perfectly smooth in the same scenario.&lt;/P&gt;

      <description>&lt;P&gt;Hello, the legacy non dch driver is the latest 15.45 graphics driver from intel's site. I uploaded the video on the original post comparing the difference between the two drivers.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I also did some digging on the issue.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;My issue seems to stem from the overall issue that is described very well in this post&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;A href="https://community.intel.com/t5/Graphics/Intel-HD-Graphics-Lags-on-High-Resolution-Displays-Not-Powerful/td-p/671766/page/2" target="_blank"&gt;https://community.intel.com/t5/Graphics/Intel-HD-Graphics-Lags-on-High-Resolution-Displays-Not-Powerful/td-p/671766/page/2&lt;/A&gt;&lt;/P&gt;
&lt;P&gt;More specifically the issue I mentioned in the post above though is related to the ANGLE D3D11 backend in chrome I believe.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I am not an expert in this stuff, however I am just trying to provide the specific information that may prove helpful in getting this bug resolved.&lt;/P&gt;</description>

      <description>&lt;P&gt;Hello&amp;nbsp;AArya9,&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Thank you for patiently waiting for a response.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;We tried doing some replication in our end and the results are the following:&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;STRONG&gt;Testing #1:&lt;/STRONG&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;UL&gt;
&lt;LI&gt;Internal mini-PC&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;CPU:&amp;nbsp;i5-7200U with&amp;nbsp;Intel® HD Graphics 620, using the driver version&amp;nbsp;27.20.100.8587.&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;Windows 2004 Build: 19041&amp;nbsp;&lt;/LI&gt;

&lt;LI&gt;Mozilla version: 80.0 (latest)&amp;nbsp;&lt;/LI&gt;
&lt;/UL&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;STRONG&gt;Results:&lt;/STRONG&gt;&amp;nbsp;We did not see any issues with this system, the scrolling was smooth with no lagging. Same results for Chrome and Firefox.&amp;nbsp;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;STRONG&gt;Testing #2:&lt;/STRONG&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;UL&gt;

&lt;/UL&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;STRONG&gt;Results:&lt;/STRONG&gt;&amp;nbsp;We did not see any issues with this system either, the scrolling was smooth with no lagging. Same results for Chrome and Firefox.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Please check the videos attached: Chrome NUC, NUC Mozilla, Google Chrome CRB, Mozilla CRB.&amp;nbsp;&lt;/P&gt;

      <description>&lt;P&gt;Hello thanks for the reply &lt;a href="https://community.intel.com/t5/user/viewprofilepage/user-id/32471"&gt;@Sebastian_M_Intel&lt;/a&gt;&amp;nbsp;.&lt;/P&gt;
&lt;P&gt;Some thing you may be missing is that my system has single channel memory, in the task manager it says "row of chips" for the memory configuration.&lt;/P&gt;
&lt;P&gt;Also my screen is a uhd (3840 x 2160) screen.&lt;/P&gt;
&lt;P&gt;As per the driver, you can manually install an unsupported driver through device manager in windows. I saw it mentioned on another thread here and I installed it for testing purposes. Although there were some issues due to the incompatability, the driver let me scroll perfectly smooth with videos on the screen.&lt;/P&gt;
&lt;P&gt;Something to note is that the scrolling issue is likely related to the D3D11 ANGLE backend.&lt;/P&gt;
&lt;P&gt;Thanks again for your help and for looking into this issue.&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Hello AArya9,&amp;nbsp;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Thank you for your clarification.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Actually, the use of single channel memory will affect using the UHD resolution, it will not work as expected as using dual channel memory. Based on that, this seems to be related to your system configuration, have you tried reporting this to your system manufacturer (OEM)? Remember that we tried replicating this behavior internally with no issues.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;

&lt;P&gt;Thanks for the reply. I have already reported this issue to my OEM and they replaced the motherboard, yet the issue is still present. This leads me to believe that this is a driver issue.&lt;/P&gt;
&lt;P&gt;My suspicions seems to be confirmed as on the 15.45 driver, the page scrolls smoothly up and down even if there is a video on the screen but on the DCH driver it lags when there is a video on the screen.&lt;/P&gt;
&lt;P&gt;Thanks again for looking into this issue.&lt;/P&gt;</description>

      <description>&lt;P&gt;Hello&amp;nbsp;AArya9,&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Thank you for your reply.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;You mentioned the OEM replaced the motherboard of the laptop, did they include the CPU also or did you have to install it separately? Did you do that before posting this thread?&amp;nbsp;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;As we did several testing with our latest drivers and saw no problem, we do not believe this can be related to our driver. You also mentioned that you tested the driver available in the Dell's website, that driver is a different package as&amp;nbsp;OEM drivers are handpicked and include customized features from their side, this also shows the problem following different drivers.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Another extra step you can try is replicating this using the&amp;nbsp;Microsoft Basic Display Adapter, in case this driver does not show this behavior it can be even a hardware problem in the graphical portion of your CPU:&amp;nbsp;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;OL&gt;
&lt;LI&gt;Disconnect from the Internet so no new drivers are automatically installed by Windows Update.&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;Uninstall the driver and the Intel Graphics Control Panel from&amp;nbsp;&lt;STRONG&gt;Control Panel&amp;nbsp;&lt;/STRONG&gt;&amp;gt;&amp;nbsp;&lt;STRONG&gt;Programs and Features.&lt;/STRONG&gt;&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;Restart the computer.&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;Confirm in&amp;nbsp;&lt;STRONG&gt;Device&amp;nbsp;Manager&amp;nbsp;&lt;/STRONG&gt;&amp;gt;&amp;nbsp;&lt;STRONG&gt;Video&amp;nbsp;Adapters&amp;nbsp;&lt;/STRONG&gt;the controller is listed as '&lt;STRONG&gt;Microsoft Basic Display Adapter&lt;/STRONG&gt;' &amp;gt; if not, repeat steps 2 through 4.&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;If the adapter continues to be listed as ‘&lt;STRONG&gt;Intel HD Graphics&lt;/STRONG&gt;’ or similar, and no other Intel Graphics driver is listed under '&lt;STRONG&gt;Programs and Features&lt;/STRONG&gt;' for removal, then it means Windows has switched to a previously installed Legacy driver. At this point we can remove Legacy drivers from Device Manager:&amp;nbsp;
&lt;OL&gt;
&lt;LI&gt;Right-click on '&lt;STRONG&gt;Intel HD Graphics&lt;/STRONG&gt;' or similar, and select '&lt;STRONG&gt;Uninstall Device&lt;/STRONG&gt;'&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;In the pop-up window make sure '&lt;STRONG&gt;Delete the driver software for this device&lt;/STRONG&gt;' is checked.&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;Click on&amp;nbsp;&lt;STRONG&gt;'Uninstall'&lt;/STRONG&gt;.&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;Restart. (Repeat steps 5.1.1 through 5.1.4 until the device gets listed as '&lt;STRONG&gt;Microsoft Basic Display Adapte&lt;/STRONG&gt;r')&amp;nbsp;&lt;/LI&gt;
&lt;/OL&gt;
&lt;/LI&gt;
&lt;/OL&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;You can also try performing a fresh reinstallation of Windows* 10, using a new image with a new bootable device and installing the OS from scratch (check&amp;nbsp;&lt;A href="https://support.microsoft.com/en-us/help/4000735/windows-10-reinstall" target="_blank" rel="noopener noreferrer"&gt;Microsoft's guidance&lt;/A&gt;)&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Regards,&amp;nbsp;&lt;/P&gt;

      <description>&lt;P&gt;Hi&amp;nbsp;&lt;a href="https://community.intel.com/t5/user/viewprofilepage/user-id/32471"&gt;@Sebastian_M_Intel&lt;/a&gt;&amp;nbsp;,&lt;/P&gt;
&lt;P&gt;I saw your reply but I didn't get a chance to reply as the school year just started for me.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;In the motherboard replacement, they replaced the CPU, RAM, and SSD.&lt;/P&gt;
&lt;P&gt;On the basic display adapter, the specific issue does not occur but performance is a complete laggy, unusable mess.&lt;/P&gt;
&lt;P&gt;As for the fresh windows install, I have already tried that and I am currently on the fresh install from when they changed the SSD.&lt;/P&gt;
&lt;P&gt;Thanks again for looking into this for me.&lt;/P&gt;

      <description>&lt;P&gt;Hi&amp;nbsp;&lt;a href="https://community.intel.com/t5/user/viewprofilepage/user-id/33398"&gt;@AArya9&lt;/a&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I would like to chime in if that is ok.&lt;/P&gt;
&lt;P&gt;Adding emphasis on the system memory configuration being 'Single-Channel': This has shown to have a direct impact on 4K performance. The integrated graphics relies on the system memory for its own video memory resources, and when we consider 4K to be quite a heavy task to handle on the video memory department (after all the 8 million pixels have to be stored somewhere) the more bandwidth the better.&lt;/P&gt;
&lt;P&gt;Can you check with your laptop manufacturer if it is possible to switch to Dual-Channel memory? By the way, I don't think you should rush and spend any extra money for now, and rather request your laptop manufacturer test this for you and confirm if it makes a difference or not.&lt;/P&gt;
&lt;P&gt;Best Regards,&lt;/P&gt;

&lt;P&gt;Unfortunately, the memory is soldered onto the motherboard so changing it isn't an option.&amp;nbsp;&lt;/P&gt;

&lt;P&gt;Also something I would like to add is that although there is general performance lag which may be attributed to the single channel memory and the 4k resolution. This thread is mainly focused on the software bug which can be seen in this video I have added.&lt;/P&gt;
&lt;P&gt;&lt;A href="https://youtu.be/xoS6_sw31yA" target="_blank"&gt;https://youtu.be/xoS6_sw31yA&lt;/A&gt;&lt;/P&gt;
&lt;P&gt;This occurs on the DCH drivers from Dell and Intel. It does not occur on the legacy intel 15.45 drivers nor on the microsoft basic display adapter. This leads me to believe that this bug pertains to the DCH driver. Also this bug is not resolution specific. If I downscale the screen to 1080p the bug still occurs, further leading me to believe this is driver related.&lt;/P&gt;</description>
