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 ...

I know you have answered your own question. But in case others don't have the same setting on their TV, but are still getting the image cropped all round, I'll leave this answer. My TV, an 8 year old Panasonic, has what it calls "Picture Overscan" where a small number of pixels, maybe 20 or so, are cropped off all round. Irritatingly enough, this is ...

VGA is analog. HDMI is digital. Meaning: the digital output of your computer is converted to the analog VGA signal. The analog VGA signal is converted back to a digital signal by your monitor. These conversions depend on the quality of the involved cable, connectors and especially the analog/digital converter components within your graphics card and the ...

No, HDMI cables don't support this functionality. HDMI does have a backchannel (CEC) which in principle could be used to carry mouse and keyboard signals, but I don't know of any hardware which actually uses it for that. You may be able to use it that way in hardware you built yourself, but it's extremely unlikely your monitor supports it. Monitors ...

Each and every VGA flat-panel display has an "Auto" button. It automatically adjusts the interpretation of the analog signal to achieve a (more or less) pixel-perfect mapping. Activate this function when the outer edges of the image displayed are clearly defined (nothing black) and you have text visible. Still, 1080p is in the upper regions of what's ...

author of f.lux here. DisplayLink does pass through DDC/CI commands to displays. We've had an implementation to do this for a few years, but we've been cautious to support this for a few reasons: Most displays store color settings using an EEPROM, and these typically have a finite number of write cycles. We could get away with changing things a couple ...

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 ...

Basically, HDMI is digital and VGA is analogue. There are a few solutions: 1) Buy a docking station which provides access to 2x HDMI or 1x HDMI + 1x DVI. 2) Use an on-board DVI instead of the VGA. 3) Buy a HDMI -> VGA converter. The 1st VGA will no longer seem blurry in comparison with the HDMI.

It turned out, there is a setting I have never needed in this TV: Changhong Chiq UHD43E6000ISN It was the Aspect Ratio = PTP (Pixel-To-Pixel? Feel free to comment, if you found a link to wiki or something, I did not). Selecting this option instead of 16:9 or Auto, fixed the problem. Original picture, Aspect Ratio 16:9, cropped After-Fix picture, Aspect ...

It is possible, but involves lots of work and is kind of useless. You wouldn't call the end result a monitor, as such -- the Paperwhite logs into an SSH session, so it pretty much only works for terminals, as the lag between wireless keyboard and the e-ink screen is around 200ms. An article about this exploit is published by Max Ogden : Kindleberry ...

The pixel clock adjusts how wide the input pixels are. VGA is an analog input, there are no clear-cut boundaries between pixels and the monitor must guess. If the clock setting gets misadjusted, your display gets blurry and that’s probably why it no longer causes interference. To adjust the clock and phase settings properly, view a pixel checkerboard on ...

As others have said, VGA is an analog signal but the pixels in a flat panel display are digital. The monitor has to know where in the VGA analog waveform to sample the signal to convert it to digital. The auto adjust feature on flat panel displays attempts to guess the best timing for that sampling. But if the timing isn't perfect, you will get a blurry ...

OK I feel stupid: the answer is to open the Intel HD Graphics Control Panel (right click the desktop and choose Intel Graphics Settings, then go to the Wireless Display section and increase the Picture Size to 100%. See screenshot below. You would think this would DEFAULT TO 100% (hello Intel???) but it was defaulted to 75%.

I do it by displaying the apps on the laptop's screen on all virtual desktops ( Win+Tab -> right click on the window -> Show this window on all desktops.

As @Wyzard says, computers talk to monitors via DDC and this uses 4 pins on the vga. See the pinout on wikipedia. A working vga cable needs all the pins wired independently from each, and also from the cable shielding to the chassis, i.e the metal cover of the plugs and sockets. Only pins 4 and 11 can be missing or not cabled. Inside a monitor there is a ...

Immediately I thought to recommend enabling HiDPI mode, which basically allows you to change the display to use half of the real pixel density without changing the resolution: sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool true but then I did the math and realized that you want 2/3 of your full ...

Multi-monitor management software is very helpful for situations it sound like you are in, however to accomplish the specific goal of accessing windows on other desktops you mention it is easily done with hotkeys in Windows. Use Alt-Tab until the window you'd like to move is selected, then press Windows-Left_arrow or Windows-Right_arrow to move the window ...

This is what worked in my case. My monitor was being incorrectly detected as a HDTV with limited range and adding a custom resolution with "CVT-RB" timing fixed it. You can add a custom resolution either in Intel HD Control panel > Display > Advanced > Add custom resolution or, in case you have newer drivers, you need to run CustomModeApp.exe manually (via ...

BenQ make a lot of them. When a new model is made - at least in the USA, a "FCC Declaration of Conformity" must be issued - stating that the screen complies with all required legislation and regulation. For the 24056FPW monitor - the declaration (link here) says it was made by BenQ A little bit of googling has sent me to other pages which also list BenQ ...

I have a Dell G5 5587 with an NVIDIA and Intel video cards. It have an HDMI port where I plugged an external monitor. Now the trick is, that the HDMI port seems to be shorcircuited to the NVIDIA card instead of passing through the Intel one, so when I close the monitor lid, the Intel card thinks that the last monitor attached to it have disconnected (which ...

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:

Detecting a monitor's resolution depends on information provided by the monitor itself via DDC. In a VGA cable, this uses several pins and wires that are separate from the ones used for the actual video signal. A cheap VGA cable might be missing some of these wires (to save on costs), or the wire might be present but broken (due to wear & tear).

Late answer I know - but I thought I'd give my two cents in case someone in the future comes across it. I have 3 external monitors running off my Dell XPS 15 laptop, with the lid closed. Obviously, you'd need to "Change what happens when you close the lid" as mentioned by the other answers. Then check in your BIOS for a "Wake on AC" option. Quite simply, ...

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 ...
