1366 x 768 resolution

[crazyburns]

I have 3 Windows Vista computers that I am connecting up to Sony Bravia KDL40S2000 LCD tvs using a VGA connection. The computers are Dells with and intel Q965/Q963 Express Chipset. I am trying to run the screens at there default resolution of 1366 x 768, but this is not an option. The only resolution close to this that works is 1280 x 768, however this leaves black bars on each side of the image. I have downloaded the latest driver but this didn't make a difference. I have tried finding a display driver for the monitor (it shows up as generic display) but have been unable to find an available one. I also attempted to use PowerStrip to set a custom resolution, but this did nothing (I've read somewhere that PowerStrip doesn't work with Intel).

I found an article where they discussed editing the [NonEDIDMode_AddSwSettings] in the driver inf file, however I did not understand what all of these diffenet settings mean. Is this the best way to make this work?

Any help would be greatly appreciated.

Which is not getting read, 1920x520? Or more appropriately, where are you looking for it?

[cdickinson66]

Wait no you're right it does appear in the drop down menu after all but as a separte resolution. 1900x1064
I thought is was a res inside the 1080 resolution so I was selecting the 1080 one.

However when I select the 1900 one we just added it just blanks out the screen and doesn't work like the 1366 one did.

Strange I wonder what exactly this HDMI input is for if it does not display 1080i or 720p correctly... It seems to only accept the resolutions givin but none of them actually fit the screen.

Try changing the vertical resolution back to normal and see if it still blanks when you select it. 1900x1080, in other words. I might have gotten something wrong when I specified it, and that could make it send a resolution your monitor can't display.

I'm not sure why it's not displaying 720p for you, since we're giving it the DTD it claims it wants in the EDID. For 1080i, it's probably just the scaling chip in the TV assuming it's being sent video with icky stuff around the edges (as in last century's TV)-- that's not uncommon at all!-- so it's overscanningby some internally set percentage before converting it to 1366x768. We're attempting to compensate for this by essentially underscanning the signal we send to it so that when it does the zoom/scaling it goes to the edge of your screen instead of beyond it.

[Aaron_B_Intel]

An even better idea... Stretch your toolbar to make it twice as big as usual (enough so when you use the 1080i resolution you can still click stuff on it).

Download Powerstrip from http://www.entechtaiwan.com/util/ps.shtm.Install and execute it.

Switch to one of the 1080i modes in DVI/HDMI-- preferably the one I provided from your EDID, but whatever you can get. Right click on the Powerstrip icon on your toolbar, choose Display Profiles | Configure. Click theAdvanced Timing Options button, then click on the Copy Timings to clipboard button (next to Cancel). Paste these into Notepad or whatever text editor you like. Label them "1080i original".

Now, down by Add New Resolution there's an icon with a triangle and a ruler which is labelled Design a resolution in a resolution when you scroll over it. Click on it. You'll get a black screen with a white outline which you should extend to the edges of your screen, where you want the visible edges to go. When it looks like how you want it, click OK. You'll be back on the Custom Resolutions screen. On this screen, too, you'll have a Copy to clipboard icon. Do so. Paste it in the same file, labelled "1080i underscan".

Get out of Powerstrip and switch back to whatever is a comfortable resolution for you to watch, then post your results from the file here. We should be able to use the same 1080i timings that you know work, along with the information Powerstrip provided, to construct working custom timings for 1080i for you to paste into the .INF file. It's a roundabout way of doing things, but it should accomplish what you want: running your monitor without such a silly amount of overscan.

Hi Archibael can you help please?

I have a Sony KDL32V2500 LCD TV, I have been looking through these various tips for a while trying to get my screen to display the native resolution (1366x768)with the intel graphics card. So far no joy.

Where would I find the correct DTD information for this screen?

Regards

Red.

[Aaron_B_Intel]

bigred07,

Can you get MonInfo to supply you with information on that TV? If so, post here andI'll try to help.

[bigred07]

Archibael,

Great thanks for the offer of help.

The information from Moninfoseems of little use, it's a Sony LCD TV 32" so perhaps it's not reporting the DTD information. I thnk I'm using the correct software (Monitor Asset Manager). It's the only montor I have attached so there is no problem there.

The machine is a media PC dual booting windows XP Home and Fedora. Perhapsthere are some Linux utilities?

bigred07,

So far I'm not finding a Modeline for your TV, but I'll keep looking. I see you're running a laptop-- is the laptop screen deactivated when you're running MonInfo? There should be a pulldown box at the top which allows you to select the monitor you want to look at.

Another trick someone pointed out to me recently is to open the Intel Display Console (should be a bluesquarein your toolbar, unless you've shut it off, click on the Information button, and then look for "Monitor" or "Display" (I'm forgetting because I'm not on my G965 system at the moment). Though it doesn't list the EDID there, if you click "Save Information" at the bottom of the box it will save a file which will contain the EDID. See if that works.

[bigred07]

Hi archibael,

Yes it's a laptop of sorts in that the components arelaptop based. But it's actually a mini PC by Aopen http://minipc.aopen.com/Global/spec_945X.htm .

Using the intel software to get the EDID inforamtion, produced the same results no inforamtion. Some LCD TV's just don't want to give it up.

Found this it's the 32V2000 not he 2500 as mine is but would it do?

http://egopoly.com/archives/2006/01/mythtv_setup_fo.html

All the best.

Red.

[Aaron_B_Intel]

Ah, yeah, I remember that one. It looked nifty.

Yeah, we can give the 32V2000 a try. Don't know if it will work, but the fact that it's the same vendor and close to the same model # is promising...

ModeLine "1360x768" 85.500 1360 1424 1536 1792 768 771 777 795 +Hsync +Vsync

The official EDID from that monitor is:

66 21 50 b0 51 00 1b 30 46 70 36 00 00 00 00 00 00 1e

The only difference between the two is that the Modeline has the image shifted by a couple pixels to the left. I'd try that.

[mediehenrik]

Thanks for your assistance, archibael.

I have just recently bought the Sony Bravia V2500 model and when I try out the above DTD, the V2500 says that the input signal is 1280x768, not the 1360 I was hoping for. :-( (The laptop, however, switches to 1360 or similar when I activate the above screen resolution DTD entry)

This is the EDID information I get from Monitor Asset Manager when running from my Fujitsu Siemens Si1520 (GMA 945) laptop. I'm new to this EDID fibbling business so I ask you to kindly assist me :-)

Here we go (VGA connector used, not HDMI)

EDIT: Now that I read what's in the report, this seems very very unlikely. Among other things, it lists the screen size as approx 13 inches. That's 19 inches too few. :) I can't figure out why Monitor Asset Manager gives this information?

So you're saying when you activate that DTD, the laptop monitor switches to 1360x768, but the TV changes to 1280x768? It might be as simple as making the TV the primary monitor, then.

[mediehenrik]

Ah, that would be too easy. ;)

No, sorry, that didn't fix the problem. Even if I go into (as I do now) external Monitor only mode, the image is being reported as 1280x768 on the LCD TV.

I tried to decipher the DTD string myself above, but that seems to only list one entry and (as I wrote) I believe the Monitor Asset program reports the wrong screen, or something, given the "13 inch" line in the output.

Definitely odd.

Anything you can think of would be helpful

[Aaron_B_Intel]

Yeah, I try to go with the easiest solution first.

Don't know why your TV thinks it's getting 1280x768, but try one of these:

66,21,50,B0,51,00,1B,30,40,70,36,00,00,00,00,00,00,1E,37,01

66,21,50,A0,51,00,1B,30,74,70,36,00,00,00,00,00,00,1E,37,01

18,21,50,A0,51,00,1B,30,40,90,13,00,00,00,00,00,00,1C,37,01

They're generic, but they might give you better results than the ones from the Bravia V2000.

[bigred07]

Hi again Archibael,

Well that last post did the tick. I set the number of DTDs in the igxp32.inf file to 5 and substituted the first code line from you post into DTD_5. It works a treat and I see no reason to try the others. The TV is now at it's full resolution and the HD sample movies I haveall look good.

Thanks verymuchfor your help.

Red.

[mediehenrik]

bigred07: That's just not fair. ;)

I guess I'm just SOL, then. Maybe my laptop somehow blocks the 1360 resolution, or some other voodoo magic, but it's good to know that that "we" have the proper entries for the V2500. If I get some other PC to hook up to the V2500, I'll be sure to try that line out.

[Aaron_B_Intel]

Never surrender, mediehenrik! :)

66,21,50,B0,51,00,1B,30,40,70,36,00,00,00,00,00,00,1E,37,01

Are you plugging directly into the laptop, or into a docking station? Might try switching to whatever method you're not using.

If you're concerned your laptop blocks 1360x768 (which seems weird if you're actually getting it as an option), you can try 1352x768:

66,21,48,B8,51,00,1B,30,40,70,36,00,00,00,00,00,00,1E,37,01

Hope you can eventually solve your problem, and sorry I failed to help you out.

[mediehenrik]

Never mind, I got it to work perfectly now. I must have made some stupid mistake earlier.

The first line worked like a charm, just like bigred07 wrote. Excellent! Thank you!

(I upped the DTD count in the inf-file to 1 and just added the first line to the first DTD entry in the inf-file. Sweet!)

[Aaron_B_Intel]

Awesome! I'll add it to the list of success stories.

[bigred07]

Archibael,

Thought I would try this on the HDMI input the TV has. Usingthe DVI output from the PC instead of the normal VGA and using a DVI toHDMI lead. The screen functions at480P but when I select 1366 x 768 the picturegoes blank. There must be something else I have to do in the drivers file, for HDMI / DVI?

Any ideas?

[richard_crossman]

Hey Guys I too have the problem with overscan and trying to get my HTPC to display in 1366x768.
Here is my setup - A-bit iL90MV Intel 945GM on board graphics.
HDMI out to HDMI in on my Samsung LE32R73BD.
Again I am having the same problem as everyone else and cannot get rid of the cropping.
