How to get wide screen 1366x720 resolution out of my external VGA port of my Intel 945 notebook graphic card.

Hi,

I have a Toshiba M115-S3094 laptop and it has an Intel 945 GPU.
My laptop's monitor's resoution is 1280x800 and its working perfectly.
The problem is where I'm using VGA cable to use with my 32" Samsung LA32R71 TV, where I can just get 4:3 resolutions and that results in stretched images.

I tried t driver called win2k_xp14324bb.exe that was for a similar problem, but I still can't choose a 16:9 resolution for my extended monitor.

I read online and they say things about EDID, I was curious to know if my external display gives proper EDID to my GPU but I have no idea how to test it.

If your EDID is available,it will be in a Diagnostics Report. Do the following and post it here:

Open the Intel Graphics Tray. Click on the Information button. Click "Save To File".

I tried PowerStrip to add 1360x768 resolution with info I got from my TV's manual but that resolution is not available in my display properties of second monitor.

Yeah, that's not much help. :(

I'd try the DTD trick listed elsewhere here (in the sticky thread at the top of this forum) with the following settings (found these in a Linux modeline for a model which is not identical to your but is similar):

84 21 50 B0 51 00 1B 30 50 70 36 00 00 00 00 00 00 1E

I love you!
YESSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
FINALLY
yessssssssssssssssssss, those magical numbers with that magical DTD software solved my problem!
I LOVE YOU!

WOW
Now I can watch pix with my TV without that stupid stretching! YAAAAAAAAAAAY!

The settings you gave me seem perfect and have no flick or whatnot, but I'm going to use my manual's settings to see if its different:
resolution 1360x768
Vertical freq. 60.015
Horizontal freq. 47.712
Pixel Clock Freq. 85.800
Polarity +/+

I was going to build a string like that you gave me (is it DTD? or EDID? I donno) but it seemed that it needs more data.

one last thing, is it possible to have a .reg file to fix this instead of using the DTD software everytime I change windows?

p.s. I love you!

The EDID is the information passed from your monitor to the graphics driver on request (which in this case was not coming over for whatever reason). A DTD is a "detailed timing descriptor" which is optionally included in the EDID. As you've noticed, it includes a lot more information than just the vertical and horizontal refresh rates, syncs, and pixel clock. Pixel clock is in most ways the crucial parameter, so since I couldn't find a copy of your EDID on the Web I looked for a Linux modeline for your monitor or a slightly similar one with the same pixel clock.

The Ubuntu forums had one with 85.8 MHz for a different Samsung model, and I figured it was close enough-- apparently I was right. I typed the Modeline data into DTDCalc and it computed the DTD.

You can construct a .reg instead of using DTDCalc each time, but different versions of Windows sometimes locate the TotalDTDCalc and DTD_1 entries in different places in the registry, so just be aware it may not work as well.

First off congradulations on your solution. I have the same problem to my tv. I can't seem to find that magical DTD software on this thread. Could you tell me where I can find it? Thank you very much

Hi there. I have a Samsung PN42B450. IT's a 42" 720P and I have the same 1024x768 widescreen stretched problem. Could you tell me where I can go about modifying the DTD? Thank you.
