    Unable to get 1920x1080 widescreen aspect ratio on 915gv

    jamy

      I just recently purchased an Acer s242hl monitor and despite searching for hours and installing the most recent bios and graphics driver I am unable to get my video adapter to allow access to any widescreen aspect ratios 16:9.

       

      The monitor's max res is 1920x1080

       

      This is my current information...

       

      Using VGA mode

      Computer: Dell E310 ( yes I know it is an old dog )

      OS: Windows 7

      Chipset: Intel 915GV

      Graphics Engine: 950 GMA

      Current Video Driver: 6.14.10.4764 (1/13/2007)

      Dell BIOS: A04

      Monitor Driver: Acer ver 1.0.0.0 (7/12/2010 for Win7)

       

      Intel Graphics Media Accelerator Driver Tool recognizes monitor and displays multiple supported 16:9 resolutions including 1920x1080, but under screen resolution the highest available option is 1400x1050 which is 4:3

       

      To my knowledge the intel driver listed above is the latest support driver for that chipset. I have read an article on the developers forum which mention that Dell may be blocking some resolutions in the BIOS ( don't know if this would be factual or not).

       

      Is it possible that either a) there may be a driver available thru intel to fix this or b) some registry settings can be tweaked to allow widescreen res for this driver.

       

      Could someone possibly point me in the right direction, would prefer not to have to purchase a new PCI card and disable the on board graphics adapter.

       

      Thanks.

          Hello,

           

          Please bear in mind that this product has reached its End of Interactive Support so Intel no longer provides interactive support for this product via telephone, chat or e-mail.

           

          Furthermore please keep in mind that this controller does not have drivers validated for Microsoft* Windows* Vista*, Microsoft* Windows* 7 or Microsoft* Windows* 8 due to hardware limitations in the older Intel® graphics controllers.

           

          For this case what you may try would be to update the BIOS in the system, make sure that the latest monitor driver is installed and then try again to see if the resolution is available. If the system reports the resolution but it is still not available as an option, in fact this might be blocked by your computer manufacturer.

            Diego_Intel,

             

            I realize this is an older no longer actively supported chipset. I have had it for well over 7-8 years. Hence my comment on it being an old dog. I am not expecting any live support from Intel on this issue. I am however hoping to find a veteran with knowledge on the tweaks that it may take to accomplish my goal.

             

            I have already upgraded the system bios to latest available for this system via Dell, which is the A04 rev. As for the video driver I understand I am using the last winxp ver. released by Intel.

             

            I have an Intel document for this particular embedded graphics adapter which states it is capable of handling the resolution of 1920 x 1080. If that resolution was available on that hardware using the latest driver on an WinXP machine, should it not provide the same options running in compatibility mode on a Win7 machine? I would think so.

             

            The monitor driver I have appears to be just fine. It is a Win7 driver version and as mentioned before, inside the Intel utility it lists the monitor as supporting the 1920 x 1080, so it is reading the monitor driver info properly

             

            I understand the process clearly of getting the latest bios/graphics driver/monitor driver. This is what I have done by tracking down the latest published drivers etc of this older hardware. What I was hoping was that someone may have knowledge of a 3rd party graphics driver which may have been developed a little more recently with support for the newer monitor resolutions, or know how to check if Dell is blocking that resolution in the bios, or a registry entry which may enable the option in windows if indeed the support is already there in the driver.

             

            I am not experienced with the fine grained details of what goes on under the hood to support certain resolutions and not support others, but I would like to think that I am not the only person whom has purchased a new monitor and put it on an old Dell E310 with a 915gv. There has got to be some way of getting it to work. I hope.

              jamy,

              I remember how this problem can be solved.
              Do as shown in the first post here.  (Yes, google translation is something crazy. But it is not difficult to understand.)

              Or just make a moninfo screenshot, I'll help to make a few lines for .inf.

                The .inf you are suggesting that you will create. Is this for the monitor? The monitor .inf I am currently using is from Acer and is the most recent for this monitor which was just purchased about a week ago. Using the Intel tool it reads the available resolution settings properly for the monitor, it is windows that won't allow setting to the resolution that I need.

                  You need modded inf not for monitor, but for intel gma driver.

                   

                  1. prepare gma driver. Uncompress it somewhere, find inf (as i remember - igxp32.inf ?).

                  2. open .inf in notepad and find this string: [NonEDIDMode_AddSwSettings]

                  3. change this 5 strings:

                  HKR,, TotalDTDCount, ......

                  HKR,, DTD_1, ......

                  HKR,, DTD_2, ......

                  HKR,, DTD_3, ......

                  HKR,, DTD_4, ......

                   

                  for:

                   

                  [NonEDIDMode_AddSwSettings]

                  HKR,, TotalDTDCount, %REG_DWORD%, 4

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

                  HKR,, DTD_2, %REG_BINARY%, 00,00,00,FD,00,38,4C,1F,53,11,00,0A,20,20,20,20,20,20,37,01

                  HKR,, DTD_3, %REG_BINARY%, 00,00,00,FC,00,53,32,34,32,48,4C,0A,20,20,20,20,20,20,37,01

                  HKR,, DTD_4, %REG_BINARY%, 00,00,00,FF,00,4C,52,39,30,44,30,31,32,38,35,33,35,0A,37,01

                   

                  1.png

                   

                  4. save .inf

                  5. uninstall GMA driver and install "Standart VGA driver".

                  6. reboot and install modded driver (say OK when Windows will warn about "unsigned" etc). See that unmodded gma driver were not installed!

                   

                  All s242hl's native resolutions must appear for choosing, include widescreen resolutions.

                  Write here about the results, please.

                    gregj,

                     

                    Sorry it took this long, just got a chance to try it out tonight. After the modifications to the driver I reinstalled and the results are that the only thing I seem to have gained from the custom driver is a res of 1920 x 1200.

                     

                    There is an issue with the 1920 x 1200 though... The quality of the graphics look good at that resolution but the desktop is then larger than the actual monitor as a result you have to pan to the left, or right, or top, or bottom with the mouse to actually see the rest of what you are viewing.

                     

                    These are the available res selections as far as windows is concerned...

                     

                    1920 x 1200

                    1400 x 1050

                    1280 x 1024

                    1280 x 768

                    1152 x 864

                    1024 x 768

                    800 x 600

                     

                    All of which were available from the stock driver with the exception of the 1920 x 1200

                     

                    I am temporarily putting the stock driver back in until/if there is something else you would like me to test.

                     

                    Thanks

                     

                    Edit: After a reboot another resolution was available 1600 x 1200 which does the same thing as the 1920 x 1200. Windows changed the resolution to 1400 x 1050 automatically after reboot.

                      well, if You are ready to continue the experiments, try this strings:

                       

                      [NonEDIDMode_AddSwSettings]

                      HKR,, TotalDTDCount, %REG_DWORD%, 5      ; This shows number of DTDs to be used. ;  0-->Disable the feature.

                      ;Following keys have 20 bytes (18 byte DTD + 2 Byte flags).

                      HKR,, DTD_1,%REG_BINARY%, 02,3A,80,18,71,38,2D,40,58,2C,45,00,13,2B,21,00,00,1E,37,01       ;1920x1080@60...Non-interlaced

                      HKR,, DTD_2, %REG_BINARY%, F3,39,80,18,71,38,2D,40,58,2C,45,00,13,2B,21,00,00,1E,37, 01     ;1920x1080@59.94...Non-interlaced

                      HKR,, DTD_4, %REG_BINARY%, FA,1C,00,72,51,D0,1E,20,6E,28,55,00,13,2B,21,00,00,1E,37,01      ;1280x720@50.94....Non-interlaced

                      HKR,, DTD_5,%REG_BINARY%, 00, 00, 00 ,00, 00, 00,00, 00, 00,00, 00, 00,00, 00, 00,00, 00, 00,00, 00 ;Fifth DTD

                       

                      2.png

                       

                      If 1920x1080 resolution will lost again, then interesting to see if 1280x720 widescreen entry appears in list.


                      Also could be that Dell blocked 1920x1980 resolution in the BIOS, for some reason (such oddity known about them).

                      Then you can try:

                       

                      [NonEDIDMode_AddSwSettings]

                      HKR,, TotalDTDCount, %REG_DWORD%, 1      ; This shows number of DTDs to be used.

                      HKR,, DTD_1,%REG_BINARY%, 02,3A,7E,1A,71,38,2D,40,5A,2C,45,00,13,2B,21,00,00,1E,37,01       ;1918x1080@60...Non-interlaced

                       

                      or:

                       

                      [NonEDIDMode_AddSwSettings]

                      HKR,, TotalDTDCount, %REG_DWORD%, 1      ; This shows number of DTDs to be used.

                      HKR,, DTD_1,%REG_BINARY%, 02,3A,7E,1A,71,38,2D,40,58,2C,45,00,13,2A,21,00,00,1E,37,01       ;1918x1080@60...Non-interlaced

                        gregj,

                         

                        Using the first option you gave above with 5 entries yielded no 1920x1080 or 1280x720.

                         

                        Tried second option with just one entry for 1918x1080

                         

                        [NonEDIDMode_AddSwSettings]

                        HKR,, TotalDTDCount, %REG_DWORD%, 1      ; This shows number of DTDs to be used.

                        HKR,, DTD_1,%REG_BINARY%, 02,3A,7E,1A,71,38,2D,40,5A,2C,45,00,13,2B,21,00,00,1E,37,01       ;1918x1080@60...Non-interlaced

                         

                        After reinstalling the driver,  rebooted and the system booted up and video was automatically recognized at 1918x1080, in addition to all of the original resolutions up  to the 1400x1050.

                         

                        I did not try the second option with the single entry. Could you please tell me what the difference is between the two? And should I try it to verify it as well?

                          jamy,

                          Difference between last two modes is only horizontal sync offset.

                          I think that I can not help you to get better result, sorry. Stay with working entry, if you happy with it!


                          But You can try to add second widescreen resolution that may be will work too:
