HDMI connectivity problems

[vipergrm]

Hi guys, I have been having problems with playback on my Tvix M5000 box. I can play through component wihthout any problems, but when I switch to HDMI, the picture keeps flowing downwards repeatedly (as if the screen is collapsing) and the process repeats. I though it may have been the leads but I bought a new HDMI lead and a new HDMI/DVI converter but I am still having the same problem. Can anyone suggest what the problem may be? Also, I notice a lot of picture break up when on 1080i mode.

Thank you,

Viper

Have you tried without converter? Just a straight DVI to HDMI cable?

I don't have one of these cables unfortunately. I have already wasted enough money on two HDMI leads and two DVI converters. I see no reason why this should not work. Is anyyone else having similar problems? Thanks

Did you try to use PAL 50Hz or NTSC 60Hz or PAL 60Hz. Maybe your display will not display one of these settings. try to change it in the display menu of the M5000.

I use myself a € 29,95 (in holland) DVI -> HDMI cable and works perfectly. even at 1080i (my tv philips 32pw9551 wont accept 1080p) the picture is wonderfull. it also depends on the source material. try to get a good test file. i use the excelent pioneer 1080i test file.

Thanks mrbigz - Yes I see what you mean about the resolution. I changed it to NTSC (even though my TV plays both) and it seems to be almost stable but sometimes the picture breaks up and it isn't scaling properly as there is maybe an inch or two missing on the right side of the picture. When I set it to 1080i I am back to the same problem, again the picture breaks up terribly. The funny thing is, I hav none of these problems whatsoever via component. The reason I want to change to the HDMI connections is because the picture is so much better. I don't know whether I should get a new set of component leads or to go HDMI. The picture via component really lacks contrast and colour sharpness. The picture on HDMI/DVI is a vast improvement. Should I complain to Dvico about this? I cannot see how the HDMI/DVI converter is incapable. Thanks

It looks like your HDMI-chipset can't handle DVI well. This happens a lot unfortunately. In theory HDMI should be compatible with HDMI in practice it is often not.

I think you are stuck using component with your display. Don't worry component can be just as good as DVI... sometimes even better (depends on taste i guess). :wink:

Thanks Woziak, You may be right. I connected my PC using HDMI-DVI and had the same problem with the screen off centre. The set I have is a Sony 50" KDFE50A10. Should I get someone out to look at this set (still under warranty) because technically speaking, this is a fault with the set. I don't want to invest in another HDMI/DVI lead. I have spent nearly £100 on the leads I have already. Thanks again
