Audio is not part of the original DVI spec......hence why it cannot handle audio.....

It can. My Geforce passes audio through DVI-HDMI to an LK450 just fine.

Not true at all, there are many video cards (and have been for years) that will provide audio through DVI with the proper DVI to HDMI adapter. I own several cards that do this, it has mainly been an ATi feature.

Again, you cannot pass audio through DVI hence the need for HDMI plug on the other end....
Why do you think older DVI monitors with speakers ran a seperate audio cable?

Since the DVI specification does not support audio transport, an interoperability problem arises when an HDMI-source drives a legacy DVI display (such as a PC monitor), or conversely, when a DVI source drives an HDMI display. While HDMI and DVI compliance rules ensure that a DVI video connection can be successfully negotiated and established (via a mutually supported display mode), the audio signal must still be transported through means outside of the DVI connection. Typically, an HDMI-equipped source will provide additional outputs for audio, such as line-level analog and SPDIF, which provide a baseline audio program (such as stereo PCM). Likewise, when displaying video from an HDMI jack, an HDMI-equipped display may support alternate audio sourcing from a separate pair of analog-audio inputs. Provision for any of these compatibility mechanisms is down to the manufacturer; they are not specified by HDMI. By 2010 nearly all HDMI-equipped sources (set-top and media-extender boxes, Blu-ray and DVD players, and PCs) provided separate analog audio outputs, and many HDMI-equipped televisions supported alternate-audio input when sourcing video from an HDMI input.
There are consumer adapters available to place between a DVI source and HDMI device which can insert a separate audio signal into an HDMI TMDS data stream. DVI connectors on PC video cards have also been increasingly able to take advantage of HDMI features such as audio output.
HDMI supports audio DVI does not.....
The video card can only pass audio over DVI when there is a HDMI device at the other end

I see a lot of dvi to hdmi talk. Does Mini hdmi to hdmi work with 4:4:4 ? That's how my video card connects to tv.

You'll need to try and locate a TV that can do 4:4:4 over HDMI>HDMI though. Is that the only connection you have on the video out?

Hey racer. I would be using a LG. I can do Dvi to hdmi if thats the best way.

My 32LK450 supports 4:4:4 chroma over dvi-hdmi cable only when the hdmi is relabeled as PC. Using RGB cable it supports 4:4:4 chroma without relabeling. Does anyone else have the same issue?
@bluekidd: If you are using a hdmi-dvi cable then try relabeling the HDMI(1 2 or 3) input port to "PC". It worked for me. If you are using hdmi-hdmi cable then you can try the EDID override fix and see if it works. If it doesn't work then you need to either use a dvi-hdmi cable or a vga cable.
Problem resolved. My 32lk450 now passes chroma test when input is set to anything via dvi-hdmi cable. I just enabled just scan(under aspect ratio) in picture settings and it resolved the issue. Thanks JoshZH.

@bluekidd: Did you see my other post. I have said that
So you don't actually need PC mode. All you need to do is set aspect ratio as just scan and you can play with sharpness. And also make sure that you test(read the very 1st post of this thread on how to test) 4:4:4 chroma. There is a world of difference between 4:4:4 and non 4:4:4.
