You need a HDMI-to-VGA adapter. Your laptop is outputting an HDMI signal which has to be converted to VGA. Some connectors are physically different, but use identical signaling - in these cases a passive adapter is sufficient. Passive means there's no signal transformation necessary. It's just two different connectors wired together. For example, DVI-A is ...

Best practice is to always power off any devices that are not designed to be hot-pluggable before disconnecting them. VGA is not hot-pluggable, therefore its cables are not designed to be disconnected while powered. That being said, in reality, it is perfectly safe. While you don’t see VGA being used much these days, it was far more common 15-20+ years ago....

Yes, it does know Monitors are sending EDID data which contains some information about the display, including its physical dimensions. Here's an example from my older question/answer: Note the Maximum Image Size row, which says 52 × 29 cm (23.4 inch). So Windows does know physical dimensions of the display. (The program depicted reads this information from ...

Many people get this the wrong way round. Signals go from > to You might think you're connecting your display to your computer, but you're not. You're connecting the computer to the display. This means your signal goes from the computer to the display - that's an HDMI to VGA connection. HDMI is a digital format, VGA is an analog format, so any connector ...

Windows works in logical units (inches). Its simply dpi divided into monitor's resolution. A logical inch is bigger on a bigger display. This tells you what windows knows. Type in a command prompt. For the monitor wmic path Win32_DesktopMonitor get /format:list For the Video settings wmic path Win32_VideoController get /format:list For a list of possible ...

I'll go through your Q point by point. Do I need (hdmi to vga adapter) OR (vga to hdmi adapter)? My common sense would tell (vga to hdmi adapter), but I am not 100% sure. Well, the exact naming of the adapter will depend on the vendor, but most vendors put the video source (computer) before the "to", and the video target (monitor) behind it. So &...

It was stated that: "The technical term for the problem is "Rapid Hot Plug Detect," but with the latest Windows Insider build 21287 or above, Microsoft has worked to mitigate the issue. With this release, when you wake up from a sleep, all your windows should appear where you previously left them. You'll need to join Microsoft's Insider ...

Often, but not always. At work we have an application that needs to know the physical sizes of monitors in order to display maps with the correct scale. We request the EDID information from Windows for that, and it works in many cases, but not always. It's unfortunately sometimes necessary that the user overrides the size manually. We haven't found a pattern ...

It is not sure if you want to identify the physical monitors or as the in devices list. If you meant the latter, replace the part "display X" with "display X in the devices list". This method only works if you can correspond the physical screen to the devices list - e.g by model numbers or disconnecting others and connecting only one. ...

Another solution, which works in case one doesn't have physical access to the monitors: clicking on Advanced display settings: It'll display the monitor name for each display:

As of the latest Windows 10 updates, this is now possible with mostly native Windows 10 controls. Settings, System, Sound, Manage Sound Devices Locate the devices that you don't want to provide sound, select them, and press the Disable button on each one.

According to industry EDID specs, monitors are supposed to supply quite a bit of information to the OS/video driver about its capabilities. That includes pixel resolutions available, clock frequencies, manufacturer name and model number, and screen dimensions to the nearest millimeter. Theoretically, that information enables the OS/video driver to perfectly ...

This behavior of Windows changes without explanation from time to time. I myself have given up on trying to force Windows to keep my icons in place, so I use third-party products to do that for me. Below are two free products that will save and restore desktop layout: Iconoid ReIcon Undoubtedly more such products do exist besides the above two.

Go to Start > Settings > System > Display and under Rearrange your displays you can drag the monitors arround to correspond with their real world placement.

Some monitors might have problems with incorrect timing. (I don't want to describe how CRT and LCD monitors work, etc. See Wikipedia pages or OSDev for that.) Some monitors, both CRT and LCD, according to OSDev Wiki page (the big bold red warning at the top of the page) can have problems with wrong timing information and disconnecting the VGA connector can ...

This is a mini Display Port. The logo over it indicates that, as does the size and shape.

Yes the procedure described in the article is no working on recent Windows 10 version. The trick is to make Windows beleive that an external screen is connected. I confirm that the BelegNeurion solution works nicely ! This is my favorite solution (neat, not hardware required) but it require device driver installation and the screen resolution is fixed to ...

What works for me is: go into fullscreen (for example via double-clicking) Press control+up Drag+drop webex window to desired desktop/display The window will then have the size it had on the other display, but double-clicking should now enter+exit fullscreen now on the correct display. (Version 41.3.5.8)

While I don't believe it's natively possible to make one display static, you can make windows static across all virtual desktops, which is an effective work-around if you just dedicate one display to a few apps. The following works for me as of Windows 10 version 20H2. Press Windows + Tab to open Task View Right-Click on the desired window Select Show this ...

Is anyone able to explain how I can see 2 USB A & 1 USB C on my laptop yet have all the above listed. How can I determine if my USB are 3.0 or not etc? All of the USB ports are USB 3.2 Gen 1 according to the specifications I found for your device. The monitor has a HDMI cable which I use plug into a USD adapter which is plugged into my laptop as my ...

The poster has indicated that the solution was found in the post How to move a fullscreen game to the second monitor?. I quote the most upvoted answer in the post: I may have a solution/workaround if you're using windows 8.1: Make your "secondary" (the one you want the game to display the game on) as primary. Right-click your taskbar and unlock ...

All cables, analog or digital, have limited throughput - you can push only so much information through them per second until problems arise. "Information" here, in context of displays, means pixel color values at some resolution and refresh rate. The higher resolution and refresh rate, the more information there is to transmit. With digital cables ...

You could find the number of monitors and used lanes by using the free TechPowerUp GPU-Z. Under the Advanced tab, you will find the monitors and the number of lanes taken by each one. From this data you may find the number of DisplayPort signals taken off the bus:

It is not possible to set different DPI with xrandr. To handle this situation, there are a number of solutions in various forums and Stack Exchange using scaling (e.g. --scale 2x2 or --scale-from 1920x1440). While these did work for me, there was a slight blurriness on the up-scaled monitor. It was not very obvious and could be missed easily, but I am very ...

According to this link: Multiple (virtual) Monitors The following command line tool can be run from within the guest VM: cd "C:\Program Files\VMware\VMware Tools" VMwareResolutionSet.exe 0 2 32 , 0 0 2000 2000 , 2000 0 2000 2000 That will create 2 screens with a resolution of 2000x2000 each.

Adding a follow up here so it ends up on the google indexes.

Mac and Windows computers have two different display modes connected to an external display: Mirror and Extend. In Mirror Mode, the computer monitor duplicates the monitor on the external display so that you see the same picture on both the desktop and projector. In Extend Mode, the external display is treated as a separate screen so that you can have ...

As of June 2021, only the Sway compositor appears to allow extending the desktop to another device, via VNC (source). Indeed, users have reported this to work fine. For instance Mutter (the default compositor for GNOME 3, in turn the default desktop environment in recent versions of Ubuntu) can create headless monitors (since version 40.0, released in March ...
