If you want to move the Zoom floating menu at the top of your screen, click and drag on the green portion of the menu. Yes, it definitely is possible to continue to screen share and use an affected computer and minimize the appearance of these gray boxes. Is there a way to minimize the impact of this issue? Now that we are all streaming video and sharing screen content, some of these systems are showing that they are not exactly up to the task for these processes.įix #2: Replace your GPU or computer with a more capable model The typical business computer has parts that meet specifications or are specced for the anticipated type of computing to be done. Most of us don’t need a souped up GPU for day-to-day business tasks like working in spreadsheets and reading documents.Įnter video conferencing and screen sharing… Graphics processing for business functions versus gaming or creative projects is what we’re dealing with. You may not be able to resolve this issue on all computers without a hardware modification – swapping out the GPU for a better unit. Simply, your Graphics Processing Unit (GPU – often referred to as the video card) on your computer can’t handle this function. Most commonly, you’ll see a gray box covering what would be the Zoom menu bar at the top of the display, chat or participant windows that may be on screen or other application windows that you have not selected to share. What you end up with are gray boxes covering up a video that is struggling to play. This increased effort requires more computing and puts more strain on the computer (CPU) and Graphics Processing Unit (GPU). This function changes the way the screen is captured to send streaming video via a tool that normally isn’t keeping up with many changes. This can happen with normal screen sharing, but is more commonly encountered when folks use the option to “optimize for video clip”. When this does not work properly, screen sharing will transmit the screen with gray overlays to hide these regions of the screen instead of making them transparent. Using layering and adaptive screen sharing, Zoom is going to “mask” or hide some of the image on screen and share what sits behind it. That’s a neat trick, right? It allows for you to share your presentation or video, but hide your chat box or other applications floating on top of your screen. ![]() The application (in this case Zoom) is giving instructions to share the screen and omit some of the image. It’s not the application failing it’s your computer that is not up to snuff. ![]() ![]() I’ve been helping folks troubleshoot this issue since 2007 (GoToMeeting/GoToWebinar back then) and it may extend to any application that can share screen content. Here’s what’s really going on and some tips to fix it or minimize its impact on your meetings and webinars. As I searched for solutions, I found a litany of bad advice on this very common issue: when sharing a screen in Zoom, especially when optimized for playing video, gray boxes appear in the sharing. I came across a lot of bad advice when I was troubleshooting a Zoom issue (different issue). In Zoom and other screen sharing applications, those gray boxes you sometimes see floating on top of your shared screen are trying to hide something for you, but your computer isn’t handling it. ![]()
