I have an FL90 notebook with gf 8600 gt in it. The problem is, this card doesn't have a dvi port, only vga. I have an LG 42LC2R TV display with 2 hdmi ports and a bunch of other video ports (s-vid, rgb etc.). I have a DVI - HDMI cable but no way to connect it to my notebook. So I bought a vivanco converter - male vga to plug into my notebook and female dvi to connect with the cable and then with the TV.
The problem is, my notebook and nvidia panel instantly found the new display and recognized it, but I have no image nevertheless, same is if there was no signal being sent from the notebook. I set my tv on dvi mode and made sure my laptop was switched to use dual display, everything seems ok on the software side. I'm not sure where might be the problem, I read somewhere that newer nvidia drivers have some issues with dual monitors and there is some fix available around, approved by nvidia that makes it all work. Another issue might be the cable. I had a stationary PC with radeon 9200 tv out some 1 year ago and it had dvi port in it. I connected the same TV with the same DVI-HDMI cable and it was perfectly ok, everything worked, signal 100% digital.
So now I'm wondering if it's either the converter's fault or maybe it's the issue with the cable itself, being a DVI-D dual and not necessarily DVI-I? That way maybe it can only transmit digital signals? I'm not sure that's the case since I believe the dvi-vga adapter emulates a digital signal from the analog vga port to send via the dvi-hdmi cable to the tv. Or maybe I'm wrong and it does try to transmit analog signal using the dvi cable/hdmi tv port incompatible with analog signals? What difference would it make if I just bought both sided RGB/VGA cable and made the connection completely analog without the need for converters/adapters and without using the HDMI port in the TV? Is there some significant quality change? If I have to use a cable connection to view HD content directly from the computer's hdd, does RGB/VGA (I believe vga and rgb are the same here, I mean the 3 rows of 5 pins port both in my TV set and notebook output) connection mean a large quality loss if I decide to use it instead of HDMI/DVI?
