How do I flash the EDID on the 2408?
Have you confirmed that they are indeed reporting incorrect EDID?
Summary of steps I did:
1. Pheonix EDID Designer -> Tools -> Extract Registry EDID -> Load correct model
2. Remove read only -> Basic Display Paramters -> Image Size... Here I had 49cm x 32cm which is incorrect as normal 22" 1680x1050 are 47cm x 30cm... I compared this to my other 2 Dell 22" and set it to 47cm x 30cm.
3. File -> Save EDID as
4. Open Powerstrip -> Monitor Information. Under Option select Update EDID and upload the EDID saved from Pheonix. Switch off pc + unplug monitor and then reboot
5. Enjoy bezel management
What you need:
Powerstrip registered version 3.74 (latest version doesn't let you Update EDID on monitor unless you mail them and get the PIN code first)
Please be careful I cannot be held responsible for damaged hardware...
