When you "hack the driver", use this:

HKR,, DTD_1,%REG_BINARY%,
02,3A,80,18,71,38,2D,40,58,2C,45,00,13,2A,21,00,00,1E,37,01

instead of the examples provided by Intel.


just try the coding you gave me...
Its show 1920x1080 27 kHz on the Intel Graphic on GMA setting

but once i select it, a message pop up from the monitor saying not support.

using the coding on the intel will have option of 30 or 25 kHz but monitor will 'flash'...

Is there any more code I can try? I had use DTDCalculator to try different setting but non of them work.

Thanks a lot of yor help

No, I'm afraid you are being limited by the Intel display driver in two ways:

1. it is not automatically enabling 1080p @ 60Hz, which it should because that is exactly what the Dell EDID asks for and
2. it is not enabling the parameters indicated in the "custom" timing registry entry, which also asks for 1080p @ 60Hz

I suspect this is a hard-coded bug in the Intel driver that wants to treats 1920x1080 as 1080i and 1080i only. If thats the case, the only way around this is to use 1920x1082 or 1920x1078.

I just try the 1920x1078 setting it pop up the same message as before:

"The current input timing is not supported by the monitor display. Please change your input timing to 1920x1080@60Hz or any othe monitor  listed timing as per the monitor specification."

Sham.... Intel reply my email and saying that my support the 1080 monitor without any problem. (I told them I need to hack the driver in order to get 1080 but flashing)

Rik Wang, is there any advice you can give me. Really appreciate that the support you giveing me here. Looooots of Thanksssssss

Hi all,
I think I am a bit overstrained by the detailed tech talk here (defenitely not just because english isn't my native language...), so I hope I can get a down-to-my-level instruction or answer here...  Smiley In the (long ago) beginning of this thread, it all started with the Intel 82852/82855 GM/GME Graphics Controller and a guy who wanted to modify output settings, so I was hoping to find an answer to wether I will be able to get a 720p DVI output out of this chipset. But unfortunatey in the course of the thread, I could't find an answer.
I 'd like to buy a cheap second hand Dell notebook that will work on both my (also otherwise used) docking stations (PR01x), in order to watch movies over its DVI out (with HDMI adapter to a Samsung LE37R81 LCD TV). Almost all noteboks I find have that Intel 82852/82855 GM/GME for graphics. So I was wondering if it actually is possible to get this resolution (720p) out of this chipset? I'd like to use the LCD TV as the only display, if that's possible with that resolution.
Does anyone have the answer to this?

Hi, it's definitely possible by using the Intel Embedded device drivers instead of the usual ones.
It's possible to obtaining the timing values for the resolution you want off the EDID record of the TV.
Otherwise it's also possible to specify the timings via configurations but it's more complicated.
My TV doesn't have the EDID record for 720p and I've never managed to find the correct timings myself, so I had to settle on 1280x768 until I get a newer TV.
A wiki page has been linked here that I've found really useful to understand the details of the EDID record.

After this discussion, support for some Intel chipsets has been added to Powerstrip but I believe not to the 82852/82855 GM/GME.

Just to clarify: it is Intel that added code to their drivers to support custom resolutions, but they never updated the i85x drivers with this code: the last/final i85x XP drivers are dated Feb'2006.

One could, however, attempt to take the last i945M drivers, dated Feb'2008, and add back in the i85x to the driver INF. The last i85x release supported the i945M in a unified driver, and the i85x may be dropped only by explicit reference in more recent i945M driver releases. Harmless to try anyway - if it doesn't work, just roll back.

Hi guys,

I've read through most of this discussion and although not all of it makes sense to me, it sounds like an issue that I am currently experiencing and was hoping for some other people's thoughts on.

Basically I have a Dell Inspiron 510m laptop and I have just acquired one of these:
LG M2394D 23" HD Ready TV/Monitor 1920x1080 20000:1 300cd/m2 5ms HDMI/DVI-D/VGA Glossy Black

As you can see the monitor supports 1920x1080 resolution (in fact it requires that in order to get the most out of it) however I cannot get my laptop to do this.  The most it will go up to is 1600x1200, even after installing the correct monitor driver etc.

I ran the Intel Chipset Identification Utility from their website which produces the following:

Chipset
Detected Chipset: Intel(R) 852/855 GM/GME chipset

Chipset Components
Memory Controller: 82852/82855 GM/GME
I/O Controller: 82801DBM (ICH4M)
Integrated Graphics: Intel(R) 82852/82855 GM/GME graphics controller

I have tried to obtain all the latest drivers I can from the Intel website and device manager now tells me I am on version 6.14.10.4497 but still no luck.

Is there any hope for this old laptop?  I'm still rather fond of it as in every other area it does exactly what I need but if there's no way it can output to my new monitor then I'll probably have to replace it Sad

Really grateful for any responses here.

Thanks guys,
S.

Hi guys,

Rookie here, been reading around and installed powerstrip myself o have a play around but to no avail.

I have just purchased a laptop with an Intel GM 965 chipset. Problem Is I am trying to get it to output @ 1920x1080 but cannot get it to do so.

I tried making a INF file but don't know whether it worked, is that what I need to do?

Any help would be MUCH appreciated as I have an incompatible screen & laptop!

Hello, I just wanted to state a huge success :

On my Dell Latitude x300 to which I hooked a 1080p monitor, I first tried to :
- install powerstrip, no success
- tweak registry values as suggested in http://software.intel.com/en-us/articles/custom-resolutions-on-intel-graphics/
- finally I installed IEGD 5.1 for both detected graphics controller in my xp 32 device manager, and everything works like a charm !
