The only things left I can think of to try is to make the Acer the primary monitor and shut off the laptop screen, and directly connect the monitor to the laptop rather than to any docking station. Also, make sure you've changed all the entries in the registry... you might have missed some (I did my first time).


I'm sorry, Makis. That's the bottom of my bag of tricks. Might want to contact your laptop vendor or Intel customer service if it's still not working for you.

Hi archibael!


Im having the same problem wiht my secondary monitor. Im using a Dell Inspiron 9400 and have a secondary monitor a Viewsonic VA1703wb 17" widescreen but i cant get the 1440 x 900 resoution, instead only letme set a 800 x 600 or a 1024 x 768 resolution. I've downloaded Moninfo, and this is the results:

Weird and unlucky for you that the EDID is not showing up. On the other hand, I found a Modeline for your monitor, so we should be okay...


Modeline "1440x900" 106.5 1440 1520 1672 1904 900 903 909 934


The latest Dell drivers from their website have the capability to do custom timings, so as long as you have those you should be fine. Look in the registry for "DTD", and change all instances of


TotalDTDCount from 0 to 1


Also, change all instances of


DTD_1 to


9A 29 A0D0 51 8422 30 50 98 36 00 00 00 00 00 00 18 37 01


the last "18" might be "1A", "1C", or "1E", depending on what your sync is. Could be any of the four.


Also, if the Dell has specifically rejected 1440x900 in BIOS, try 1432x900:


9A 2998D8 51 8422 30 50 98 36 00 00 00 00 00 00 18 37 01


Make sure you change all the instances in the registry-- there are several duplicates.


Hope this helps,


AB

Adrian,


Given that your monitor is telling the world through EDID that it likes 1280x720 best, I'm not surprised that's what the drivers want to give you.


However, if you try the registry tricks I've detailed above, using:


51 35 A0 F0 51 84 28 30 60 98 13 00 00 00 00 00 00 18 37 01
in DTD_1 for 75Hz refresh


and


97 29 A0 D0 51 84 20 30 50 98 13 00 00 00 00 00 00 18 37 01


in DTD_2 for 60Hz refresh


you should be able to get what you are looking for.


Hope this helps!

Hi Archibael,


Thanks for all your posts - I've learned a lot.


My particular setup (as of Christmas) is Acer Extensa 5620 with the GM965 X3100 and an LG 37LC7D panel over D-Sub, running Vista. I'm trying to get the native 1366x768 for the LG to work. I wish I could provide the EDID for the LG but it's being reported as a non-PnP device in Vista, and I believe this is why neither the Intel Info. page nor MonInfo can help.


I have been able to run the LG at 1280x768 without any issues, and I hope with your help I can get it to display at the native 1366x768.


Thanks,


Julius

Strange that the EDID does not list amode for 1366x768, which should be native.


LGManual claims that the panel is plug-and-play. These modes are listed as supported:


1280x768: Horiz. Sync 47.776 kHz Vert. Sync 59.87 Hz


1360x768: Horiz. Sync 37.72 kHz Vert. Sync 59.799 Hz


1366x768: Horiz. Sync 47.13 kHz Vert. Sync 59.65 Hz


Hope that this may be more helpful.


Aaron Brezenski (Intel)'s picture

Yeah, the TV is providing a 1360x768:


66 21 50 b0 51 00 1b 30 40 70 36 00 c4 8e 21 00 00 1e


Not sure why the X3100's not seeing the EDID while the 945G does; some graphics and monitor chips don't like each other. There is a new registry setting called "BitBashingSupport" which is supposed to help.It's set to '0' by default, but you can set it to '3'(it's in multiple places in the registry, so get them all) and it might read the EDID better.


Regardless of whether the read happens or not, the above DTD should work for you. If you're extremely upset about the extra six pixels missing per line, you could also try


66 21 56AA 51 00 1b 30 40 70 36 00 c4 8e 21 00 00 1e


but that might be a little off center, or even unaccepted (given that the manual lists a different refresh rate for 1366 and 1360).

jelenart's picture

thanks archibael,


setting BitBashingSupport to 03 in the registry fixed the TV PnP detection.


However using the 1360x768 EDID sent by the TV produces an offset and mis-sized image. Seems like the problem may be stemming from using this panel over D-Dub as opposed to DVI. I'll give ita shot with my desktop over DVI and see what happens.


Thanks again.

Hoping you can help me too.. It seems like you are the master at this particular topic.

I have a Toshiba A135-S4478 running Windows Vista Business.

I also have an Acer AL1916W monitor that's native res is 1440x900. I used to be able to run at this resolution without a problem. Lately I can't select the 1440x900@60 like I used to, and have spent considerable time correcting this unsuccessfully.

I can select from a numer of different resolutions but none are 1440x900.

The link you posted to which part of the ini file to edit is dead. I've poked through the ini file but couldn't figure out where to enter new lines. Can you help?

Wiki describing .INF hacks:

According to your EDID, you want


9A 29 A0 D0 51 84 22 30 50 98 36 00 98 FF 10 00 00 1C


as your DTD.

Can you get EDID information with either MonInfo or by using the Intel Graphics Tray's "Information" button (you have to Save to File to get the full Diagnostics Report with the raw EDID)?

The EDID you posted is for the laptop's screen, unfortunately. Don't know if this will help, but make sure "DDC/CI"supportis turned on (page 17 of the manual).

I'm a novice on this stuff so apologies in advance...


I ran MonInfo and it provided the following info below. Interestingly, all the online info on my LCD TV (Toshiba 32HLV66) indicates that it has a native resolution of 1366x768 but that doesn't appear in the MonInfo data.


I've played around with the settings currently supported by the driverand 1280x720 looks the best - but I can't see the edge of the screen. For example, the "X" to close windows isn't visible.


Is it possible to get an option for 1366x768 or something close?

Andy,


It is not uncommon for TVs to fail to accept their native resolution over HDMI/DVI, even if they do accept it over VGA. Sometimes not even over VGA.


Though not every TV model in the world is listed, a good place to start looking is

Hi archibael,

Sorry to jump in here and hijack the thread but I have a similar problem and would love to get your assistance.

I've been reading most of the threads on this forum and have seen your excellent tutorial at the wiki on hacking the .inf file but I am still not too sure on how to proceed.

To start things off here is my situation: I am trying to use a widescreen monitor with my laptop and need to get the monitor to recognize the right resolution (1680 x 1050).

I think the second profile belongs to my laptop (please verify if possible) and the first profile somehow doesn't give me the EDID date that you need.


So my question is .... do you know how I can proceed from this point? Please feel free to suggest anything.. I'm desperate to get the right resolution and I do appreciate all the help I can get.

Thanks in advance!

Archibael,



I am having an unusual problem that EVERYONE in the manufacturing chain seems to deny responsibility for. I have a GateWay MP8708 notebook with the 945GM chipset. I purchased a Viewsonic VA2226w 22 lcd monitor that runs at native 1680x1050 resolution.



The problem is that the image is blurry due to stationary ghosting around all my icons and text. It is not a cleartype issue nor a cabling issue. Something appears to be out of phase and I have no idea how to approach fixing it as Intel, Gateway and Viewsonic all deny that it is their problem.


I have updated all the drivers related to my computer (with the exception being mentioned in the next paragraph). I have not upgraded my bios as the option is not available at this time.



Oddly, when I upgrade to the newest 945GM graphics driver I lose the ability to use the 1680x1050 resolution at all. When I roll back the driver to the June 07 update, the option is again available, but the ghosting remains.



Do you have any clue what might be the cause? I have searched far and wide for a solution and have been denied. Is it something as simple as a missing line of code? Im to the point where I would even paypal you some cash if you could give me some insight that would resolve this issue as it is seriously interrupting my work schedule.




With nothing connected to the external vga port I get the following options:

Brad,


Use the tool at


http://software.intel.com/en-us/forums//topic/56423


Use the "Reverse Calculation" feature with the following string I found in your Viewsonic's EDID as reported above:


21 39 90 30 62 1A 27 40 68 B0 36 00 EF 23 11 00 00 1C


You sound like you think your problem may be hsync/vsync out of whack. Change the last digit from 1C to 1E, 1A, and 18 in turn to switch the hsync/vsyncs around.


If that doesn't work, you may be seeing the effects of a known bug with panel fitting on 1680x1050, but I thought that was listed as fixed in the 15.7.3 drivers.

bmowell's picture

Archibael,


It doesn't seem to be out of sync vertically as it only ghosts to the right of my icons and text.


I downloadDTD Calculator but when I click the "reverse calculation" tab and paste:


21 39 90 30 62 1A 27 40 68 B0 36 00 EF 23 11 00 00 1C


into the field and hit the "reverse calculate" button. I receive a beep noise that sounds like an error beep.


I've tried typing in each of the following in succession


21 39 90 30 62 1A 27 40 68 B0 36 00 EF 23 11 00 00 1E


21 39 90 30 62 1A 27 40 68 B0 36 00 EF 23 11 00 00 1A


21 39 90 30 62 1A 27 40 68 B0 36 00 EF 23 11 00 00 18


and clicking the "reverse calculate" button after each entry but I always receive the error beep.


What am I doing wrong?


Thanks,


Brad

Too many spaces between 2nd and 3rd numbers? Trailing spaces at the end?

bmowell's picture

Archibael,


Got rid of the space that I didn't notice before.


Typed in the following in succession


21 3990 30 62 1A 27 40 68 B0 36 00 EF 23 11 00 00 1E


21 3990 30 62 1A 27 40 68 B0 36 00 EF 23 11 00 00 1A


21 3990 30 62 1A 27 40 68 B0 36 00 EF 23 11 00 00 18


clicking "reverse calculate" after each.


What do I do after this? Anything?

bmowell's picture

Archibael,


I went back and read the directions and did figure out that I needed to include each value on the registry hack screen before I clicked the registry hack button.


My only question at this point is, do I include ALL the values, ie. the one with 1C, 1E, 1A and 18 or only 1E, 1A and 18?


Thanks,


Brad

Archibael,


I tried it both ways, and unfortunatley it didn't fix the problem.


Thanks,

One problem is it's hard to be sure when you go this that the 1680x1050 resolution you're sending it the one that's being used; perhaps the default is being used instead. Typically I modify the rez to be 1678x1050 or something, just so I can tell that it's mine and not the default one.


Like I said, there was a known issue on some drivers with double-scaling 1680x1050, so this may be that. It's supposedly corrected on the latest, so if they're not working for you I'm at the end of my ability to help you.

Hi archibael,

If you have the time, could you please take a look at my issue and let me know if you have any solution? My previous comment is here:
http://softwarecommunity.intel.com/isn/Community/en-US/forums/permalink/...


Thanks a lot and I really appreciate your help!

Aaron Brezenski (Intel)'s picture

Sorry, slowdive, I saw that and thought I'd dealt with it.


Did a Google search and got nothing back for your monitor model number +EDIDor with +Modeline, which is stymieing the effort.That's really the best way to proceed. If Intel Graphics Tray "Information" button, plus Save to Disk (gives you different information than the "Information" button alone) doesn't produce a readable EDID for that monitor (which is certainly how it appears from your post)... can you plug it into a different system and use MonInfo to get the EDID from there?


Failing that, on newer Intel drivers there is a registry setting called (I believe) "BitBashingSupport". Finding all instances of this setting in the registry and changing them to 3 may help in getting the EDID to be read better by the Intel drivers.


Again, if you can find someone out there who has your monitor working in Linux or in Powerstrip or in general can grab the EDID, I think I'll be able to help you out.

rldzq,


Everything I can determine about your monitor indicates it has 1024x768 pixels; only the 50PV70 has 1366x768. But I was only able to find English language manuals for 42PV70F, not C. Is there a reason you're trying to drive 1366x768?

I hope you can maybe help me on my issue as well. i've already done a lot of searching on the net, and tried many different settings, but can't get full screen in the 1366x768 res. setting.

What do i use as a setting in DTD to be able to get full res?

VGA, DVI, or HDMI?


Having a hard time Googling for a good Linux Modeline for your screen; most people are giving up and going with 1280x720 or something similar.

pwvandeursen's picture

archibael,

My stysem is currently connected through dvi. I have it now full screen from top to bottom through: 768, 771, 777, 806. However from left to right Istill have a partly blank screen. strangly enough it doens't matter if I use 1280 or 1366, the same part of the screen is blokked out.

Any settings you would recommend to try?

thanks

Patrick

Aaron Brezenski (Intel)'s picture

Can you try it over VGA, and post the EDID from that?


There are some cases where TVs don't accept the same resolutionsover DVI or HDMI as they do over VGA, and if that's the case there's not much you can do about it as the issue is internal to the TV. The number of folks on the internet who are having this problem with other video cards and your monitor implies this might be the case. Let's try to find out.

Hi Archibael,


Sorry about my english !!!


I already tryed a lot of things to get a 1360x768 resolution in a Samsung TV with a VGA connection on my ASUS W7F notebook with a 945GM.


I insert in the DTD_1 (igdlh.inf) the red value below on a Raw EDID.


Values that I already tryed:


66 21 50 B0 51 00 1B 30 40 7036 00 75 F2 31 00 00 1E (1360x768)


66 21 4F B1 51 00 1B 30 40 7036 00 75 F2 31 00 00 1E (1359x768)


After insert that values as a DTD_1 and select the 0 (zero)value to 5, to able the customs resolutions, I unistall the 945GM driver and afterinstall the new driver with the corrections.


The problem is: I never can see the new value of resolutionon the display settings.


Can you help me?


Thanks

Aaron Brezenski (Intel)'s picture

Did you append 37 01 to those in the .inf file?


If so, can you use the Find function of regedit to check your registry? Keep checking all instances of DTD_1 and make sure they have the right string populated, and TotalDTDCount to make sure it's >1.

fireyes's picture

Hi Archibael,


The 37 01 (bytes) I appended in the .inf file. I'm sure about that.


All the instaces of TotalDTDCount is >1. I'm sure about that too, because I checked.


I don't know what is happen.


Aaron Brezenski (Intel)'s picture

You may have put the 37 01 in the .inf, but it would not be the first time they didn't show up in the registry.


If they're in the registry and you're still having no luck, I'd try one of the older drivers (15.6.1) where it worked. I'm getting some reports of nothing > 800x600 working on some systems on the 15.7.x drivers, but there's nothing I've been able to find common in the cases.

farmermark's picture

Wow archibael, just got finished reading your Wiki .inf hacks, quite a lot to swallow yet very informative. Without giving much thought to resolution settings, or lack of, I purchased a Samsung SyncMaster 932BW (1440x900) so I could have dual monitors with my Toshiba A105-S4004 laptop. I use two monitors at work and enjoy the advantages. By now you know what the problem is, but I really like the widescreen monitor. I have studied your forums for two nights and finally read the .inf hack. So Im going to give it my best shot with hopes you are still available when I hit a snag. And how can Intel ignore a situation thats affecting so many people ? Idiots could probably write a fix in ten minutes !

Aaron Brezenski (Intel)'s picture

I suspect that like most people, their driver guys are overworked and under-resourced. I know I am.


I'll be around to try to help.

farmermark's picture

ok, I admit, I tried the easy way out (Powerstrip) with negative results. But Im still going to give your hack a shot, if nothing else, its a learning experience. Couple problems I ran into already is with MonInfo. I can get full results on the laptop display including the raw ECID but depending on the display config MonInfo will only show basic info on both. Im not sure if I have to make the Samsung the primary display then run MonInfo or what ? Maybe you can shed some light on that. But here is the bigger problem, Im not the sharpest tool in the shed, know my way around the computer pretty well but never got involved with HTML or editing. So now for the other problem...when I extract the driver file to text editor (I have windows notepad and Crimson) its all in code, not sure how to convert it into text in order to edit it. Am I on the right track here ? or am I in over my head ? Willing to learn if your willing to help, Thanks !

Aaron Brezenski (Intel)'s picture

Hmmm... the .INF file should not be binary, should be pure text. Sure you have the right file?

DTD

Just as you said the custom resolution value is zero. I assume we have to change the "0" to "1" and replace the first 18 bytes with the new DTD, Is that correct ?

I still have not been able to get the Raw EDID from the Samsung 932BW. We know that the native res. is 1440x900, do we really need the Raw EDID ? If so, I hope someone else either has it or someone knows how to get MonInfo to retrieve it without ripping off my laptop display... thats humor.
Thanks !!!

Aaron Brezenski (Intel)'s picture

Your understanding of the technique is accurate. There are literally hundreds of ways to specify timings for 1440x900, so it's tricky to do so without having someone with EDID or the Modeline.

farmermark's picture

Thats the reply I expected. So now that I have an understanding of all this, Im down to somehow retrieving the EDID and Modeline. I was hoping you had it. As explained before MonInfo will only read the laptop display, unless you or someone knows some trick Im missing. Correct me if Im wrong, but the EDID and Modeline will be the same on another monitor of the same make and model, right ? I will continue to search online if this is true, although I feel more secure reading it from my own monitor. Thanks for sticking with me on this !

Aaron Brezenski (Intel)'s picture

Same make/model = same EDID.

OK, I will keep searching. Worse case scenario I disconnect Samsung monitor and take it to my work place and hook it up to my laptop there, because oddly enough when I run MonInfo on my Dell laptop with a external monitor, same config as home, it displays info for both displays. Strange huh ? maybe because the Dell Latitude has a ATI Radeon chipset ???
