HD & PC Resolutions?

[knowley]

Hi people,

I've got the JVC LCD 32" HD tv and I am trying to connect a computer to it using a DVI --> HMDI cable. When the pc boots up the screen displays the picture fine and a label appears on the screen indicating its receiving a 1080i signal. After the windows loading screen has finished scrolling all I get is a blank screen.

I presume this is caused by the windows drivers setting the resolution etc - its currently set to 1024x768 (VGA socket only takes that so I've not changed it yet). I am running an ATI x800xl card, and in the control centre I've added the HD support for 1080i - are there any other settings I am missing?

Thanks very much

try pressing Alt and F4 together - that should switch between monitors - you can then set your resolution to what you require.

could also have somthing to do with frequency. Check see what the max frequency on your monitor is. (60hz or higher?)

ummmm ALT-F4 is for closing applications!!!

My Laptop (not the machine I am connecting to the TV) has dual function F keys, and the F4 key does switch screens but NOT with the alt key... have to use the special blue Fn key.

Aren't all LCDs 60hz? I will check the manual later...

50 or 60 Hz is all my tv supports according to the specs in the instructions.

Just booted up the machine using the VGA cable. Switched over to the DVI cable and flicked the channel to the HDMI input a picture was briefly displayed with the correct colours etc; but then went blank. My graphics card detected the HD TV ok cause I had a message about the audio cable.

Does anyone know the resolution I should be trying this at? 1024x768 doesn't seem to work... or maybe its something else?

I can only use HD resolutions via DVI on my projector, perhaps you have the same thing on your display, do you have an option in your menus listed EDID?

There are too many acronyms in this AV game.... not sure what EDID is, but yes the ATI Catalyst Control Centre does mention it. The ATI CCC even detects my TVs model number etc, but no resolution I try will stay, on various different res. I do get a picture (which looks great) but only for a few seconds before the TV decides to not accept the signal. I have this feeling I am missing something fundemental, but haven't a clue what...

See if you can find anything referring to EDID in your TV menu then set it to EDID2

Ahh the TV menu, theres nothing about EDID in there - thanks anyway.

try installing Powerstrip, have a google on it, it is a free download

I've got that installed already for increasing the gamma on certain games, will have a look at the other options thanks.
