On a WIN10 Pc. i have a in-screen PC (no extra box), and a second screen connected by a cord/wire (forgot what its called)

is there a way to find

a) Which screen is the main computer / CPU etc.. and the other is just a screen..

and

b) the name/type of the second screen (not the PC) - so i can tell the retail store what ive got.

ba) the type of connection i have (I forget the word)

Ps Ive switched screens in the past so screen 1 is screen 2 and screen 2 is screen 1. so i cant rely on the screen numbers.

I dont have that right-click option. However I DO know how to swap displays (if i want to).

But that doesnt tell me WHICH one is my main PC & which is the 2nd-screen

Unplug the cable connecting the two. Whichever one still works has the CPU.

You'll also probably find that the actual computer is heavier, thicker, and has things like an Ethernet port, headphone sockets etc.

Mighta missed the point with that one (have a re-read what OP is actually asking) ;)

All-in-one + monitor.

Now to the question at hand. There will only be 2 cables to the LCD. Power, video in. And a lot more to the all-in-one.

As for model. Back panel near said input holes. Front panel menu button will show on OSD incl model of a pure LCD if newish

Or if that is hard on then run up 'powershell' and use these 3 lots of commands

1 Model and make of PC

2 Serial number of PC

3 Monitor detail

Get-WmiObject Win32_ComputerSystem | Select Manufacturer,Model

Get-WmiObject Win32_BIOS | Select SerialNumber

function Decode {
If ($args[0] -is [System.Array]) {

[System.Text.Encoding]::ASCII.GetString($args[0])

}

Else

{

"Not Found"

}

} echo "Name, Serial"

ForEach ($Monitor in Get-WmiObject WmiMonitorID -Namespace root\wmi) {

$Name = Decode $Monitor.UserFriendlyName -notmatch 0

$Serial = Decode $Monitor.SerialNumberID -notmatch 0

echo "$Name, $Serial"

}

As for connectors. Colour coded. And google can help

White - DVI,

Blue - VGA,

Black with kink 1 side and a 'D' - DisplayPort,

Black with curved kink both sides like your TV cables - HDMI

gordonisnz: ... is there a way to find ...

a) Answered above by granada29 and SomewhereSomewhere and andrewNZ

b.1) Generally, the manufacturer has a logo on the bottom frame. Next, find the model number on the sticker at the back.

b.2) Post legible pictures of the front of your monitor & the sticker into this thread.

ba) See my post above

Actually, dumbest option... which has the power button that you push to turn the whole thing on? That's the actual computer.
