Cant get 1920x1080

[xo___]

I have purchase a Dell s2409w monitor, the max resolution for it is 1920x1080.
But I don't know why I cant get the 1920x1080 for my laptop. The max I can get is 1680x1050.... :(
I have read one of the artical on intel web site http://software.intel.com/en-us/articles/custom-resolutions-on-intel-graphics
And I manage to 'hack' the driver, now I can get the resolution 1920x1080 but the monitor keep flashing, because the kHz I can choose on Windows is 30 or 25 eventhou on the driver I set was 60 and 50.
Is there any driver I can download that allow me to use 1920x1080 easily.

Thanks

p.s. I have already try PowerStrip with different modeline, DTDCalculator,Intel IEGD, doesnt help. (may be I didnt use the software correctly)

Which DTD are you using when specifying a custom resolution? And what is your monitor reporting via EDID?

I have try many many different DTD already, including all DTD at DTDcalculator andthe EDID is

So you already tried

02 3A 80 18 71 38 2D 40 58 2C 45 00 13 2A 21 00 00 1E

with no success?

Have you tried seeing if it's a BIOS limitation by doing 1918x1080:

02 3A7E 1A 71 38 2D 40 58 2C 45 00 13 2A 21 00 00 1E

wow.... its working, but why is it happen? Do I need to hack the bios in order to get that 2 pixel? But I dont have any problem in linux.

thanks

Vendors can specify in the VideoBIOS a section called a Mode Removal Table, which specifcally shuts off one or more video modes they (for some reason) don't want users to have access to; the Windows driver follows this directive. I can't speculate as to why this is done, but when someone says the words "laptop" and "can't get [XxY resolution] to work with DTDCalc", it's the first culprit I look for.

In Linux, the drivers have long ignored the VideoBIOS, which is why you don't have this issue there.

Obviously in his case the BIOS + Windows driver restriction is counter productive. The shipping of 1920 x 1080 monitors with 16:9 instead of 16:10 has just been started. I wonder what is supposed to come here.

For him the best thing to do is get in touch with Lenovo to get an updated VBIOS. Since Lenovo is a brand his chances are not bad. Or is there an undocumented "Registry key" which overrides the BIOS removal list for the Windows driver?

[Aaron_B_Intel]

Yes, would be nice to get Lenovo to change their VBIOS behavior instead. Perhaps an email to them asking them to remove 1920x1080 from the Mode Removal Table of their BIOS would result in improvement if you could get to someone in Support who had the authority and expertise to doso.

Other option is to go with 2 extra pixels (1922x1080):

02 3A82 16 71 38 2D 40 58 2C 45 00 13 2A 21 00 00 1E

He'll get all the pixels he paid for (+2) but he'll still get scaling on full-screen 1920x1080 video playback, which can be non-optimal.

Dont think Lenovo will give me any support, since I email them last week, and still have no reply at all....

BTW (1922x1080): 02 3A82 16 71 38 2D 40 58 2C 45 00 13 2A 21 00 00 1E

doesnt work.

[Aaron_B_Intel]

Ah, well, it was worth a shot.

There was once a bug in the linux intel driver which would always output the resolution off by one pixel e.g. 1920 x 1199 instead of 1920 x 1200. I have a DVI display that always me to change the interpolation between three different behaviours 1:1, stretch to screen, stretch and keep aspect. So 1:1 should have given me a crisp image, but it didn't. The screen logic tried to interpolate half of the image which resulted in half of the image being blury.

We don't know what his display logic does when sending custom resolutions. It might be that there exists a resolution which results in a crisp image and maybe which has only a couple of black lines on top and below to fill the 16:9 screen. But it may also be the case that such resolution doesn't exist or is to small to be useful or only results in blury interpolated images. At the current stage it's unknown whether there exits a walkaround for you.

Getting in touch as a single person with a big company and provide a good bug report and get help isn't easy. In general they have a hierarchy of support levels in place and only once you climbed up far enough, they can help you. That isn't easy and requires a lot of patience. Especially since you need to have some kind of feeling what the current support level needs as information. It's always worth asking at the right moment to escalate the problem to the next level. I think you do understand now more about the problem itself and maybe can come up with a "better" bug report to lenovo. Better than "XY doesn't work".

I have the same problem, and I can't get 1918x1080 this way. May be I didn't the right way.
Why don't you create a driver with this modification, so everybody can easily set that resolution.
otherwise, please describe how to do it.

what I did is, change:
HKR,, DTD_1,%REG_BINARY%, 01,1D,80,18,71,1C,16,20,58,2C,1A,00,00,00,00,00,00,86,37,01 ;1920x1080@60...Interlaced

in the diverFolder/graphics/igxp32.inf

and then reinstall the driver.
