**HELP! HDLink tearing – sync probs?**

[Del Chapple]

hmm.. the hdlink will automatically switch between hd/sd. it wouldnt be unheard of that you got a bad box from bm, maybe try a firmware update on the box. my hdlink has always needed to be played with to get it to work and then it works for a while just fine.

Oh arse…the HDLink will only ‘work’ (i.e: display anything AT ALL) when the monitor’s last config on the pc is 1600×1200 – which means an SD signal is either absolutely tiny, or way bigger than screen size at 2x size…but it’s still tearing and out of sync regardless. It’s the same input as I use for my decklink and that syncs up just fine.

I’ve got latest firmware and Utility app installed off the BMD website already and no joy. I’m really loathed to go through every single driver version on their site incase something else works. I spent most of last week doing that to get my Decklink working!

Why is nothing ever simple!?! I fear I may have wasted

SD just displays as 2x (which is still smaller than hd). My next step would be to find out if its the hdlink box or the monitor. Or maybe the hdlink doesnt like the monitor (refresh rate?). Take the hd link back and get a new one it might just be broken or have a bad firmware load, because it should just work.

ps.. i dont ever remember setting the monitor up on the mac before install of hd link, the hdlink is literally the video card (HDSDI to DVI).. Can your monitor handle what the hd link is asking it to do. 1920×1080 48i (23.98psf), 50i etc. check the Monitor specs..

My monitor only handles 1600×1200 – maybe that is it? But I should be able to see 1 x SD footage at the very least. That said though 2 x 720 = 1440 pixels, which is well shy of 1600.

Gonna try some diff inputs and older firmware and see what happens. Haven’t got time to send back and wait for a new one unfortunately. I need this working by end of tomorrow!

arrgghh.

Hi,

There’s really no need to setup the display resolution of your monitor before connecting to the HDLink as HDLink will tell the monitor what it wants.

If your monitor is 1600×1200, it should still handle 1x SD.

What you can first do is to update to the latest driver which will also prompt you to update the firmware of your HDLink. See if that helps. There may also be incompatibility issues from which you can manually over-ride in the HDLink Utility preferences under EDID over-ride.

Failing which, you should speak to support and see if it’s a bad unit which we can swap out for.

Hi Kristian,

UPDATE – I got the signal to stop jumping by changing in the preferences to 1:1 progressive display, so now I can get a picture. But unfortunately when I select 16:9 I lose a load of the image off the sides at 2 x size..is there no way to make the HDLink scale it *down* in the Y height to letterbox it instead? Viewing x1 SD on a 20″ monitor is tiny.

I know this is a primarily geared HD product, but I am desperate to make this work! I am away as of monday and need to leave a working Paintbox behind for my cover!

Can I put a feature request in for the next update of HDLink utility? To allow 16:9 scaling in EITHER Leeterbox OR horizontal scaling!? That might make the difference bwetwen me keeping the box or having to send it back. 🙁
