Habt ihr das Roundup bei Xbitlabs gelesen?
Weiß net obs hier im Thread schon gab aber ich zitiere mal:
To learn the name of the matrix manufacturer, take a look at the sticker on the rear panel, under the connectors. If it reads “Model: 226BW [R] ”, then this is a Samsung matrix. If the last letter is A or C, then the matrix is manufactured by AUO or Chi Mei, respectively.
This method is not accurate, though. Sometimes the label doesn’t tell the panel type right. And there are batches of this monitor that don’t indicate the panel type at all.
In this case you can take a look at the monitor’s service menu. Set both contrast and brightness at zero, press the Menu button, then press and hold the Source button for 5 seconds. The screen will appear to show you the manufacturer and name of the panel. It is CMO M220Z1 in the photo above and AUO M220EW01 in the photo below.
If the appropriate line contains “AMLCD 220M1” instead of the manufacturer’s name, then the matrix is made by Samsung (the LTM220M1 model).
