I'm curious, does any HDCP Compliant HDMI switch support DVI over DVI-HDMI cables? Cause I have an LG 22" LCD that has DVI and VGA ports,  I have already tested my DVD player with a DVI-HDMI cable, it works on my monitor. I want to know if i can get a switch and plug my computer in to the switch with a DVI-HDMI cable, the DVD player in too with a HDMI-HDMI cable, and then from the switch to the monitor with another DVI-HDMI cable? I have found a $50 2 to 1 switch that doesn't explicitly say it supports DVI, and a $99 4 to 1 switch that does say it supports DVI, would the $50 2-1 switch work or do I need one that says it supports DVI?

If your monitor and DVD player sync OK you should be alright. I'm afraid with HDMI you never know till you try. Suggest buy from somewhere like DSE where you can return it if it doesn't work.

Too expensive! I'm a teenager with a part time job! Thanks for that though, will see if anyone else has anything else to add. Cheers

Ok well I have done more research and it turns out HDMI is completely backwards compatible with DVI in both directions. Thanks for the help anyway, cheers mate. Mods can you close this thread please =]

Whilst DVI and hdmi are completely picture compatible, you may have problems with copy protected hdmi signals (from a freeview approved set top box for instance/bluray output etc).  Even if a DVI port says it's hdcp compatible, (as stuzzo says) you still need to try first because it is not always compatible in this circumstance.

Agree with Jaxson, while DVI and HDMI are pin compatible, it is the HDCP handshaking that is your major concern here and there are various implementions of HDCP, so YMMV.

Well I'm wanting to show both PC and DVD Player input on my 22" LCD with DVI, and I have tested both separately through the monitor and they both work, I take it what I am trying to do should work then?

Yeah I'm wanting to do exactly the same thing. I've got a HTPC and I want to buy and xbox360 and easily switch between them.

Works sweet for me! Bought a Pudney and Lee Premium Gold HDMI switch off trademe for $38, plugged everything in and it all goes sweet.

Are you using DVI or HDMI input on your TV/Monitor?

Hi,

I have a DVI out & a HDMI out on the back of the leadtech 8500GT.  Is it possible to have both going at the same time?   So I can have the DVI going to a monitor and the HDMI going to my LCD TV.

Currently I can only get the monitor to display a picture, or if i unplug it and plug the LCD into the DVI. 

How do I turn on the HDMI out?

I'm using DVD out to DVI in on a 19" monitor. I intend to use DVI>HDMI cable to from the PC to the switch; HDMI from the Xbox360 to the Switch and an HDMI>DVI cable from the switch to the monitor. Should work ok? Just have to try it I guess.


@ImNotADJ:

I think you should be able to do a clone mode and output the same ting to both, but in this case you'll only be able to output a single resolution so if the devices don't ahve the same native resolution then one of them will be running at the wrong resolution.

I have this problem with my 19" TV (monitor) and my projector; the projector is 1024x768 and the monitor 1440x900 so I just have a single display and switch between them when I want to watch a moive. It would be nice to just be able to tunr the projector on and the TV off but oh well.

If the 360 works on your monitor without the switch, then theoretically it should work with the switch
