It looks great with a generic DVI-HDMI adapter but as soon as I start using the audio-enabled ATI Adapter/Dongle the video goes to Hell.


This is happening on both my 4670 and and 4870.


There's a thread from '09 on ATI forums but there's no resolution.


I have tried only on my Viewsonic 37" LCD and not my projector (not mounted yet) but i have to assume it would be just as blurry on the 1080p projector as it is on the 720p LCD. The guy's on the ATI site with this issue are all running 1080p.


Thanks for any help.

There are 2 different ati dongles I believe one for the older 200 300 series cards and a newer on for 4000 series cards can you make sure you have the correct one also are you using the latest catylyst drivers? I only have the 2600 series card and the dongle works great It must be a bug thats the end of my suggestions im afraid.

Update: Tried toggling every setting i could find in catalyst control, still looks like a Playstation 1 game: Not a smooth line to be had.


I can alternate between the ATI dongle in one port and the generic one in the other and the difference is night and day.


I don't remember if the dongle I'm using came with my 4870 or the 4670 but it gets the same result on either.


Thanks for the reply. Believe it or not just knowing SOMEone is using it succesfully helps a bit

Well I've tried everything under the sun.


My conslusion is that the problem is either the result of a bad dongle from ATI (in which case I'm screwed)


Or


My POS $500 LCD TV just doesn't like the signal from the ATI card. It handles the Audio fine but the video quality is unwatchable. (unless using a standard, non-audio DVI-HDMI adapter).


I'm going to:


A - Try hooking it up to my BenQ W1000


and


B- Never buy another ATI card again (My 4670's fan was defective from Day 1) I take it very persoanlly when products purchased at full price are defective and this issue pushed me over the edge.



Will still be checking this thread often so please feel free to add any info you can.


Thanks

Exactly what cards do you have (brand-model)? I've never seen an ATI card with an HDMI "dongle". The dongles usually have s-video, composite or component out. A card in this series would normally have a DVI to HDMI adapter that passes through audio also (in fact, 7.1) or have HDMI out to begin with.


You do have the HDMI audio drivers installed and selected in control panel?

yes, same res. as before when it looked crisp (1360x768). In fact I can switch the cable from one port to the other (one with ATI adapter, one with generic) I will get an image at the same res. both times but it looks like crap thru the ati adapter.

Both the 4670 and 4870 are Radeons.


HDMI Audio is the only audio device installed at the moment. Currently default device.


When installing latest CCC I was sure to select HDMI drivers as well (they are not part of the express setup)


As for dongle vs. adapter, well it wouldnt be the first time my nomenclature was off. But it seems about 50% of my google hits on the subject reffered to it as a dongle so who knows.




Thanks

This issue has been around for a long time with no real solution, except generic DVI>HDMI adapter which apparently solves the PQ but busts the HD (or any?) audio over HDMI. Having said that, my old ASUS 690G mobo passes audio and video over a DVI>HDMI cable.

Yeah saw that thread. Like All others I've found on the subject there is no resolution to the issue.


Even the ATI forums where some of the responses are from ATI staff yielded no results. Whatever the issue is ATI is aware of it and has got nothing to say.


I've owned about 6 ATI cards in my life and about 5 Nvidia cards. I've never had a defective Nvidia card and this is the 3rd time I've had an ATI card crap out. Granted it's less sever then other failures, with an aftermarket fan the card is still usable to a degree but not the way it was advertised.


I need to learn to ignore reviews and go with experience.

well if you google ati hdmi adapter conventional retailers have it as well. Again, its a bit cheaper than buying a new card. Nvidia has problems too.

The next time I place an order for PC stuff I'll try to do it from a place that sells the adapter (looks like it's just newegg)


I'd be shocked if a new adapter makes any difference at all though. If that fixed the problem I think someone would have discovered it by now and it's never been mentioned in any of the threads I've searched.


Looks like it's SPDIF for me till I can switch to an Nvidia card.
