[CRITICAL] Toshiba M45-S269 thinks its fullscreen, not widescreen

[tsfroggy]

Hello all,

I think I seriously messed up my wife's poor laptop.

Whilst trying to get her Toshiba to run 1680x1050 on this monitor, I added a DTD spec using DTD calculator and it worked for a little bit. Actually, it worked fine on the Samsung, but when I got to the Toshiba I somehow really fubared the main laptop screen.

The picture I'm about to show you is very disturbing, but not very clear. Kind of like a blurry murder scene.

I am knowledgeable about computers normally and thought this DTD thing would be easy, but now it seems I really messed something up.

I have tried:
Installing and uninstalling Intel's and Toshiba's display drivers.
Messing with DTD Calculator to get 1280x800 to just work, but alas - it will not.

The problem is (even when I'm rebooting!) the monitor no longer recognizes itself as widescreen. I have no idea how to fix this.

If anyone can help me please let me know.

Regards,
TSFroggy

Not able to tell here which graphics driver you're using... 14.25, or IEGD?

[Chuck_De_Sylva]

Also, you'll get a quicker response to this if you go to the OEM or support.intel.com. This forum is really tailored for software developers.

I cannot find my issue in support.intel.com, nor have I found a proper place to pose my question.

I feel that my problem is very unique; I cannot find any others just like it, which is frustrating, because most questions on the internet can be answered if only someone else had the problem first.

I am using the latest drivers for my laptop.

Even when I have the hard drive removed, the computer still starts in this resolution. I think somehow I wrote bad values to the EDID chip and it is now suffering me with a bad screen effect, for lack of a better term.

If you can point me in any direction that will take me closer to solving my problem, I would sincerely appreciate it.

[tsfroggy]

I honestly feel as though I have damaged my LCD. I think, not knowing what I was doing, I set a resolution in DTD and tried to use it, and my LCD did not like it. Perhaps I set the refresh rate above what it was capable of, and damaged some of the hardware.

I don't care if I have to replace some parts. I just need to know what parts to replace.

This is definitely a problem because it happens even outside of Windows.

Do I need to replace the LCD?

You can't actually "write" to the "EDID chip" with graphics drivers, so that's not a problem. Laptops sometimes capture the "last known good" video mode before shutdown and start back up in that mode when they're rebooted-- even prior to the OS booting-- and this is likely the behavior that you're seeing. Your EDID shows 1024x768 as your maximum rez, and that would not change regardless of which DTD you attempted to drive.

In the Intel Graphics Tray, there should be a setting for "Maintain Aspect Ratio" and "Full Screen". Try the latter.

[tsfroggy]

I have tried that, but it didn't work for me. If you check out my picture you can see that it only fills a part of the screen - it doesn't even stretch the rest of the way, and at the bottom it just shows up strange (it just duplicates several lines of pixels and stretches mouse cursors and the like that go down to the start menu bar, and there is a line to the right of the screen that displays what is on the rightmost side of the screen. Someone tell me that this can be considered normal... I have tried restoring my computer to before I messed with it, but it did not work.

Would formatting work? Would a complete erasure and restoration possibly fix my problem...? My wife is not a fan of the idea, because I just reformatted and she was not happy with the results (she lost some mp3's. :P)

I guess you tried already to reset system state to a date before fiddeling with the DTD Calculator.

If this does not succeed: Find the appropriate DTD modeline in the registry and remove it:

It is true that you need some 3rd party softwareware like PowerStrip as well, but certainly it's possible to write to the EDID EEPROM inside the monitor. In general after enabling EDID write in OSD. But he would know if he had done that besides the fact that it's crazy to write something in firmware without having tried that in software before.
