DVI - any clues?

Question

This is sort of a follow up.

I'm using a DVI/PS2 KVM switch between my two computers. Works beautifully. Reason for the PS2 is one of the computers is an old Acorn RPC which uses PS2 only. It has a aftermarket video card which does DVI.

What I want to do is run a feed to a second monitor - actually an 'HD ready' TV with HDMI input. The TV handbook says max VESA 1280 x 768 at

48.1 kHz/60Hz - but referring to its VGA input.

I purchased from Ebay a DVI to DVI splitter with an HDMI output. Looking more closely ;-) it does say DVI-D. Just inserting it between cable and monitor stops the monitor working. It shows no input. The KVM switch says DVI-D/DVI-A. It came with input cables - the output cable from it to the monitor came with the monitor, and is a DVI-D single link.

I'm confused. ;-)

It'll probably do 1920x1080 and/or 1280x720 via HDMI Strange that it doesn't just say DVD-I instead What flavour of DVI does the Acorn output? -A or -D

No - it says out of range at over 1280 x 768. It's quite old. I found a DVI to HDMI adaptor and tried driving it straight from the computer - it sort of works, but the picture is well off centre. Like a timing error in analogue.

Just says single link DVI. D only, I think.

That is interesting as it says the maximum resolution single link is

1600x1200 60Hz - yet I can use native on this monitor which is 1920 x 1080 at 61 Hz. The cable between the KVM and the monitor is definitely single link by the pins.

Dragged the computer and a full HD TV together - and the TV works perfectly on its HDMI input from the second DVI output on the Acorn. Which is all I really want. On any resolution, too.

So it looks like I'll have to get a small full HD TV for what I want.

Discovered that using the DVI to DVI+HDMI splitter in the feed to the main monitor works just fine with a modern TV HMDMI input. So it appears there was something odd about the one on the Humax TV.
