DVI-I (and by extension, DVI-A) has + (with four surrounding pins) where DVI-D has - (with no pins). A DVI-A cable/adapter male will not plug into a DVI-D female because the | blocks it.

It's not the issue though in this case. I'm under the impression the TV EDID is messed up and NVIDIA is known to have major problems when it is (wrote a program for it a while ago at the behest of @Solaris17 -- I still don't know how it works :laugh: ). The only solution is to avoid EDID which means analog. The TV is purpose built for this because it has a dedicated "PC" in with VGA + 3.5 mm stereo receptacles.

Hi Guys,

I'm testing now with 2 cables in the same time (DVI/HDMI and DVI/VGA).
Windows sends the same image on both and the entry is swapped on the TV.

When I set 1360x768@60 with HDMI, my TV displays 1360x768@60, but curiously when I set 1360x768@60 with VGA, my TV displays 1280x768@60 !?

Consequently, I tried to set 1280x768@60 with HDMI and the result is better, equivalent to VGA.

I don't understand why...

As I said, EDID on that monitor is FUBAR. VGA knows what is what. ;)

Hello Guys,

I've finally solved my HDMI problem in setting the TV sharpness parameter to 0 (instead of 70).

If someone can explain...

I have no explanation for this but I found that turning off every feature on a tv and using the gfx control panel gives a much better picture all around...except on tv's that have a port specifically for pc...
My LG works fine as a monitor... My Insignia tv does not until its feature are turned off

Yes, with a sharpness parameter to 0, the HDMI picture becomes equivalent to the VGA...
