nvidia 6150 DVI to HDMI

[iz40]

I hope this is the proper forum...

I am trying to connect my ASUS M2NPV-VM (6150 based montherboard) DVI interface to my Philips plasma TV HDMI interface. It doesn't work at all, I get blank screen, VGA works just fine.
Asus tech support simply stated "Sorry, DVI output in M2NPV-VM does not support the converter", which is odd since I thought they are electrically compatible.

anyone ideas?

Yes, it should be compatible.

I would try setting your resolution to something low and standard before switching to DVI. Perhaps 1024x768. Plasma shouldn't have any trouble displaying that resolution. (you can increase it later if you get it working)

Sometimes there's issues with handshaking on HDMI. You might have to play around with the order you turn on the TV and computer. Also, make sure the TV is already set to HDMI input when you turn on the computer. Some TVs have trouble handshaking if you switch from another input source after the computer is on.

This might sound silly, but make sure your Asus board is actually outputting a signal on DVI by using another montior if you can. Also, make sure your 6150 refresh is outputting at 60Hz. If it's defaulting to something like 70 or 75Hz it might not produce a signal on your TV. (out of range)

I tried playing with the order of switching on the PC and plasma, nothing works. I don't see the BIOS POST which is very low resolution so it would seem that the resolution is not the problem.
I saw two solutions to a similar problems in the forums, one stated that the same problem was solved when he switched to a dual link DVI cable, very strange since I thought that the 6150 DVI interface is a single link. The other solution is even more bizarre, someone is saying that there is a HW problem in the motherboard causing the EDID to not work properly and a resistor had to be soldered on the mother board to solve it.

does any of this makes sense?

I have a Philips 37" LCD and had similar trouble using any nVidia card with DVI and converting it to HDMI. Philips tech support told me that the TV requires HDCP for the HDMI ports to work. I just ended up getting my X1600Pro HDMI which supports HDCP and then it started working. Cards I tried btw were a 6800Ultra, 7600GT, 7800GTX, 6200, 6200TC, and my onboard 6100, none of which would work.
