    1360X768 resolution on HDMI not supported by Intel® Desktop Board DG41TY

    dmahaur

      Hi,

      I bought a Intel® Desktop Board DG41TY today and installed the latest display drivers from the website.

      My LCD TV is connected to the DVI port thru a HDMI converter. However, the display is very distorted since it is running in 1280X720 resolution.

      My LCD TV supports only 1360X768 @ 60Hz but I cannot seem to find that setting.

       

      Please help.

          Since there has been no replies on my post earlier, let me just elaborate the problem I am facing.

           

          Currently I have upgraded to a Intel® Desktop Board DG41TY which has a Intel® Graphics Media Accelerator X4500 integrated graphics subsystem.

          It also features both VGA and DVI video outputs. I had used a NVIDIA DVI to HDMI converter and a simple HDMI cable to connect it to my LCD TV (Samsung LA32R8).

           

          I am running on Windows XP Professional and I then installed the latest Intel® Graphics Media Accelerator Driver for Windows XP* Ver. 14.38.6.5082.

          My LCD TV manual says that it supports a PC resolution of 1360X768 @ 60Hz. However, the same is not available in the Display properties.

           

          My query is as below.

          1. Does a DVI connection to the LCD TV gievs the same piture quality/contrast as a VGA connection?

          2. The current resolution that the graphic card is running on is 1280X720 @ 60Hz can it be changed to 1360X768 @ 60Hz.

           

          Kindly assist.

           

          P.S. My earlier motherboard was working fine with the LCD TV with VGA connection.

            I just bought a DG41TY as well and have set my Dell 2709w to 1280x768 on VGA since 1280x800 isn't supported. 1360x768 is one of those resolutions such as 1280x800 & 1440x900 that the GMA cannot display for some strange reason. I have 2 black bars about 16 pixels wide running horizontally on my display.

             

            This issue has something to do with the drivers or the GMA chipset so rest assured that you aren't the only person fustrated with GMA 4 Series.

              I did found a workaround that problem. I got borrowed a generic  Samsung monitor from a friend and connected it to the VGA port. I disconnected the LCD TV from the DVI port and reinstalled the same video drivers on the machine. On restart, I connected my LCD TV thru the VGA port and I could set it to 1360X768 @ 60 Hz

               

              The system is working fine for now, but a major reason I bought DG41TY was that it boasted of a DVI port (that i could use a HDMI input to my LCD TV).

              Looks like I cannot take advantage of the DVI port and have to be content with VGA only.

               

              My original query still stands --- Does a DVI connection to the LCD TV gievs the same or better picture quality/contrast as a VGA connection?

                DVI is completely digital and the quality is apparent (more crisp display) compared to vga which is analog. I prefer using VGA & HDMI on Intel 4 series motherboards since the the DVI output from the GMA is giving me such a headache.

                 

                Glad to read that you've improvised a solution.

                  I finally found out the root cause of the problem and it does makes me look very silly.

                  Like always, the solution is there in the manuals, this time it was in the TV manual.

                   

                  The Samsung LA32R8 has 3 HDMI input sources. However, when using an HDMI/DVI cable connection, it is only possible from the HDMI 2 IN terminal. The excerpts from the manual are as below

                  - When connecting this product via HDMI or DVI to a Set Top Box, DVD Player or Games Console etc, make sure that it has been set to a compatible video output mode as shown in the table below. Failure to observe this may result in picture distortion, image breakup or no picture.
                  - When using an HDMI/DVI cable connection, it is only possible from the HDMI 2 IN terminal.
                  - You should use the DVI-to-HDMI cable or DVI-HDMI Adapter for the connection, and the "R - AUDIO - L" terminal on DVI for sound output.

                   

                  The dektop board drivers did recognize the display correctly this time and the display was adjusted automatically to the correct resolution.

                  Like Alex had mentioned in the post above, the quality is indeed crisper and much more improved.

                   

                  Now I can finally enjoy the HDMI quality display on my television and all it took was to put the cable in the right hole of the three available ;-)
