HUGE HDMI vs DVI Diplay difference - Page 4

post #31 of 36
It is best to use a DVI>HDMI converter, rather then straight HDMI for ATI cards to TV, as ATi cards seem to apply weird scaling and colour filters, at least in my case, when i was running triple 40 TVs.

And "grain" that "disappears" over the VGA is actually just being hidden by the loss of quality which causes a blur on the picture, making it look better to the untrained eye.

Just rehooked up my hdmi to check it out, man text and stuff seems like they are thicker in some spots and stuff and looks all weird. This time i decided to open up heaven benchmark though and wham it was brighter and alot more vivid than my dvi to vga im used to, might have to keep it hooked up just for games

The problem your running to really is the difference between a tv and a monitor. If you were using a monitor you would not notice a difference between DVI and HDMI. They will both be digital and all or most display setting will be at the cards end.
In you case though you are using a tv which is optimized for movies or videos rather than text.

The banding might just be a bad vga cable. Have you tried using a different one?

As far as I know, it seems ATI specific. I've tried it with an HD5450, a GTX470 and an 8800GT. The only one that screws up on both my TV's is the HD5450.

As others mentioned, check your underscan/overscan settings, and most importantly the refresh rate. Mine always defaults to 1080i, even when setting with CCC.

I went and changed display settings in the Windows display settings and it seems to hold much better.

Definitely check the pixel layout settings.
There are a number of settings that are hidden and sometimes need to be set/forced manually.
Try setting everything you can manually in the ati control center.

Make sure the tv hdmi mode is set properly as well. Mine has hdtv and pc modes for the hdmi connectors. Also some of the hdmi ports support extra features. Maybe try a different port.check that your tv supports the resolution/bit depth you are try to send it. Make sure the cable supports the resolutions and bit depth as well.
