Windows 10: What is this random graphic that showed up on my screen?

This 1" x .25" black rectangle with a red square and part of a white letter appeared on my Chrome screen a few minutes after I signed onto the internet tonight. I'm in a public parking lot. I signed into Optimum Online, a free public wifi. A few mins later, THIS.Can't figure out how to get rid of it. Switched internets dis-connected the Optimum, signed on via Dunkin' Donuts and it still won't go away. It's also on the screen when I'm on Word. What is this thing plz and how do I get rid of it?

VMWare VMs Black Screen - Windows 10 3D Accelerator - Graphic Properties not available

I am running Windows 10 Build 1803 build Citrix Desktops. I am trying to change the properties of the Windows 10 box so that I can turn off 3D Graphic properties as VMs are all in black screen mode. So, based on the suggestions by most of them, it looks
like we have to turn off the 3D Hardware acceleration. When I right click on the desktop, I get only Display Settings and Personalize option and if I go into Display settings, i do not get to see the options for 3D graphic acceleration as mentioned in the
below steps As, I do not see Graphic properties at all.

So, how can I turn it off or what else can be done as these are Citrix Desktops that are showing black screen. So, either you have to boot them serveral times or shut down and bring it up and sometimes they come up to the logon screen and show the windows
screen or else they are black screen. Clicking on CTRL+ALT+DEL also has issues sometime it brings up the logon window or else none. Just plain black screen.

In order to disable 3D hardware acceleration, I suggest you to follow the steps below.

1. Right click on the desktop and select Graphics properties.
2. Select Basic Mode and hit OK.
3. Go to the 3D option.
4. You can disable 3D graphics acceleration from this screen.

Hope this helps. Please reply for further queries on this.

graphics card problems

Hi,

Your computer makes a noise or beeps from your internal speaker because it failed to detect the graphics card. What we can suggest is for you to try cleaning your graphics card with a pencil eraser. Here are the steps below:

• Turn your computer off.
• Pull out your video/graphics card.
• Rubbed the cold contacts with soft pencil eraser.
• Connect your video/graphics card back to the computer.

Kindly note that this is just a temporary fix. If the case still continues, I suggest that you contact your graphics card's manufacturer.

Let us know how it goes.
