Can not get 1360 x 768 Native resolution for a Samsung LN37A450C LCD TV - Intel G45/G43 Express Chipset HDMI output

[chamathguneratne]

I am using a Dell Studio Slim desktop with a Intel G45/G43 Express Chipset HDMI output, to connect to a LN37A450C 37" samsung LCD TV with a native resolution of 1360 x 768. But I cannot get that resolution to work.

I used a computer with a NVIDIA card, and got the following EDID information using the MONINFO too.
00,FF,FF,FF,FF,FF,FF,00,4C,2D,AC,03,00,00,00,00,2E,11,01,03,80,A0,5A,78,0A,E2,BD,A1,5B,4A,98,24,
15,47,4A,21,08,00,01,01,01,01,01,01,01,01,01,01,01,01,01,01,01,01,66,21,50,B0,51,00,1B,30,40,70,
36,00,A0,5A,00,00,00,1E,01,1D,00,72,51,D0,1E,20,6E,28,55,00,A0,5A,00,00,00,1E,00,00,00,FD,00,17,
3D,1A,44,0F,00,0A,20,20,20,20,20,20,00,00,00,FC,00,53,41,4D,53,55,4E,47,0A,20,20,20,20,20,01,BF,
02,03,1A,F1,46,84,05,03,10,20,22,23,09,07,07,83,01,00,00,66,03,0C,00,10,00,80,01,1D,80,18,71,1C,
16,20,58,2C,25,00,A0,5A,00,00,00,9E,8C,0A,D0,8A,20,E0,2D,10,10,3E,96,00,A0,5A,00,00,00,18,02,3A,
80,18,71,38,2D,40,58,2C,45,00,A0,5A,00,00,00,1E,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,
00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,61

Which I translated to the following DTD using the DTD calculation tool:
66 21 50 B0 51 00 1B 30 40 70 36 00 A0 5A 00 00 00 1E

But when I try to implement this resolution, the LCD TV goes blank and says "Mode Not Supported".

What can I do to fix this issue. You help is much appreciated.

PS- when I use a PC with a NVIDIA card and connect via DVI, I get the native resolution of 1360x768 and everything looks very smooth and clear. With the intel card, the picture is not very smooth (especially fonts)

Thanks!
