I need dump of EDID of v2045

Postby numand » Tue Apr 03, 2012 18:21

Hi,

First of all, English is not my native language so I may write something wrong.

Due to an unknown cause, resolution of this laptop's screen turned into 1280x1023 from 1280x800. I tried to find out what the cause is and saw that EDID of screen had changed and it shows native resolution as 1280x1023, instead of 1280x800. In order to revert it, I need EDID of this screen.

Checksum: Not OK
EDID Version: 1.3
Manufacturer ID: SEC
Model Number: 0x3245
Manufacture Time: 2004-W00
Display Input: Digital
Monitor Size (cm): 33x21
Gamma Factor: 2.20
DPMS Modes: None supported
Color Mode: RGB Multicolor
Additional Info: SAMSUNGLTN154X3-L01
Timing: 1280x1023 @ 47 Hz

I use Ubuntu 11.10 as operating system.

Could you provide it for me?

Thanks and sincerely

The latest version of EDID is 1.3 that can be used in LCD laptop screens, future EDID versions promise more parameters and configurability.
1.3 is the current.
Ubuntu 11.10 display drivers or monitor INF files must be overrideing the EDID setting and is causing this problem.
make sure your BIOS is up to date. http://support.ts.fujitsu.com/Download

I think the problem lies in the Ubuntu see here: http://ubuntuforums.org/showthread.php?t=316985

Hi @sabrex,

Thank you for your concern on this issue.

1280x1023 resolution mode is read from BIOS. BIOS screen is also in 1280x1023 resolution. So it means this problem is not related to OS.
I got EDID information via read-edid package which is for Linux OS, then tried to override it, changed native resolution 1280x800 but this also did not work.

I will try to upgrade BIOS.

Thanks,
Numan.
