GTS 240 DVI to HDMI no Audio

Hi everybody,

I have SONY TV that interface design is more effort is needed to. We see this even HDMI interface offers the following two audio interface, while HDMI can transmit audio itself. In fact, this was as much now HDMI equipment, a considerable number of friends are using the DVI interface device. But just because television provides a digital interface, it is HDIM, but no HDMI devices at home friends often turn to buy a HDMI-DVI cable. This can easily connect, but there was a problem which is that many manufacturers think HDMI is both audio and video transmission, so there is no separate audio inputs available. Using nvidia GTS 240 for PC.

Actually, AV is the field of digital video values from 16-235, while the PC is always 0-255. Although the HDMI specification that when access to the signal source from DVI, you need to change to a compatible DVI1.0 mode, but there are three exceptions, so if your TV appear gray lost, either graphics card or TV manufacturers lazy or is touched the three exceptions. Practice in many high-end DVD or TV, projectors have the option of "FullRangeRGB" and "RGB" mode, to adapt to different situation. So this is the issue exactly.

It seems the problem is still out on the graphics driver. You need to installed latest version of graphic drivers. You reinstall about installation, choose not to install the driver, the system installed and then install your video card CD-ROM, all the drivers are installed. Also most have large LCD's - DVI Interface DVI HDMI switch, then would lose gray , however, did not we think the actual effect of the difference, my cousin LCD home only HDMI, so use a DVI to turn, but without the great.

HDMI single and dual-channel two points, two-channel class interface with TypeB, 29 signal lines, but we generally use are Type A class I, 19 pin. A class I have three pairs of signal lines used to transmit digital signals, three of the six lines used to make shielded cable, data, video or audio, regardless of content. DVI has two sub-channel and dual channel, single channel using the three pairs of signal lines to transmit data, three for shielding, some other for other signals. The dual-channel is not used to open the channel 6 the other three signal transmission lines. We often talk about DVI-HDMI is used in both single-channel mode, so only the three data channels.

In GTS 240, audio signals are carried through DVI when the video card detects a connected HDMI display, which is connected via the HDMI adapter which is optionally supplied by the manufacturer. it appears that the 2400 Pro models do not come with the required adaptor) .Translation as follows: For GTS 240, when the card is detected by using the HDMI adapter (provided by the manufacturer) transferred to the HDMI device when the sound signal will be transmitted through DVI.

HDMI, can usually provide up to 5Gbps data transfer bandwidth, and can transmit uncompressed audio and high-resolution video signals. Important feature of HDMI is that it requires a HDMI cable, you can complete the synchronous video signal transmission, as in the past no longer meet the needs of multiple wires, can achieve higher quality audio and video transmission. At the same time, because without the signal before transmission / A or A / D conversion, audio and video transmission quality have been effectively protected.

From DVI HDMI interface technology, which mainly Silicon Image's TMDS signal transmission technology as the core, which is why HDMI interface and DVI interfaces to each other by means of adapters convert the reasons, and its pins and DVI-compatible, but using different packages. Compared with DVI, HDMI can transmit digital audio signals, and increased support for HDCP, providing a better DDC optional features. In principle, HDMI is fully backward compatible with DVI.
