I'm usually connecting my laptop to a larger screen. I'm away from my desk for a few days and Je voudrais know what model of monitor that is. Je viens de remember the manufacturer, size and and native resolution. Je sais that Windows remembers previously connected monitors and their settings. Does it also remember more details about them, like monitor model?
Puis-je view a list of monitors that were connected to a computer in the past? J'utilise Windows 10.
Comment puis-je view a list of all monitors connected in the past?
Re: Comment puis-je view a list of all monitors connected in the past?
Apparemment, Windows collects EDID information (Extended Display Identification Data) from all displays that were ever connected to the machine. There's a tool from the awesome NirSoft called [MonitorInfoView](http://www.nirsoft.net/utils/monitor_info_view.html) that can show that data:
At this point it was obvious for me which entry is the one Je cherche, but let's assume J'ai un lot of entries and J'ai to narrow down the set of results. Sizes and resolutions can be viewed by double clicking list entries, how about manufacturers?
Manufacturer name is encoded as the manufacturer ID. Here's how to do that manually. My monitor is manufactured by Iiyama. First, I look it up on manufacturer's list. Here's [a large one](http://www.uefi.org/pnp_id_list) and [a shorter one](https://github.com/GNOME/gnome-desktop/blob/master/libgnome-desktop/gnome-pnp-ids.c). Find your manufacturer's three-letter code. For Iiyama it's `IVM`.
Then substitute each letter with a binary value from the list below:
```
A 00001
B 00010
C 00011
D 00100
E 00101
F 00110
G 00111
H 01000
I 01001
J 01010
K 01011
L 01100
M 01101
N 01110
O 01111
P 10000
Q 10001
R 10010
S 10011
T 10100
U 10101
V 10110
W 10111
X 11000
Y 11001
Z 11010
```
For `IVM` I get:
```
I 01001
V 10110
M 01101
```
Notez que one letter can appear multiple times, eg. `SSE`. Concatenate these binary values. Vous devriez get a 15-bit number:
```
010011011001101
```
Now vous devez convert this to a hexadecimal number. Wolfram Alpha is always handy in such cases:

[010011011001101 base 2 to base 16](http://www.wolframalpha.com/input/?i=010011011001101+base+2+to+base+16)
Result: 26cd16
Now swap 1st character with 3rd one and 2nd one with 4th one:

`26cd` → `cd26`
Make letters uppercase and prefix with `0x`:
```
0xCD26
```
This is the value vous devriez look for in the *Manufacturer ID* column:
