Hello List,<br><br>I now have my MythTV setup pretty well sorted. I have everything I need working and all my shows setup on a schedule. So far it is working beautifully, no problems to speak of in the last couple weeks, the WAF is way up too!! I am a happy camper, this is miles ahead of my Windows setup I had previous to this and to think I was using 2 commercial apps and it came no where close to what I have with Myth. I am so glad I decided to learn Linux and made the jump to Linux on both my machines(Myth and my Office setup). Big thanks too all the programmers, theme builders and everyone else involved with the project.
<br><br>My last remaining issue is to get my tv working at 1080i. Right now I have it working at 480p which is pretty decent and everything is working well but I know the TV is able to do 1080i as that is what I was running at with my Windows setup. For the life of me I just can't get it working at 1080i and I have tried numerous settings etc.
<br><br>I am running on an Nvidia-6600 PCIe card which is hooked up via DVI to a 34" Widescreen RCA Scenium CRT(Yes a CRT!!), Love this TV. Although I would like the get a projector sometime down the line as my basement is perfectly suited for it, but that's for another day.
<br><br>My first step involved booting into Windows at my desired settings which actually turn out to be an underscanned 1920x1080i setting, works out to be 1768x992i, it works at 1920x1080 but there is alot of overscan so I would prefer the 1768x992. Anyways, I noticed within the windows Nvidia drivers there was a selection for "Advanced Timing". I figured this was perfect as I could simply write down the timings and somehow extract a ModeLine. Here is what I have from the Windows driver at my desired res:
<br><br>Horizontal:<br><br>Front Porch = 88<br>Sync Width = 48<br>Back Porch = 296<br>Sync Polarity = +<br>Back End Active = 1920<br>Front End Active = 1768<br>Scan Rate = 33.75kHz<br><br>Vertical:<br><br>Front Porch = 4<br>
Sync Width = 10<br>Back Porch = 118<br>Sync Polarity = +<br>Back End Active = 540<br>Front End Ative = 992<br>Refresh Rate = 30.026Hz<br><br>Which I interpreted as Modeline "1768x992-HD" 74.250 1920 2008 2056 2352 1080 1084 1094 1212 interlace +vsync +hsync
<br><br>Just for Comparison here is the settings for true 1920x1080<br><br>Horizontal:<br>
<br>
Front Porch = 88<br>
Sync Width = 48<br>
Back Porch = 144<br>
Sync Polarity = +<br>
Back End Active = 1920<br>
Front End Active = 1920<br>
Scan Rate = 33.75kHz<br>
<br>
Vertical:<br>
<br>
Front Porch = 4<br>
Sync Width = 10<br>
Back Porch = 30<br>
Sync Polarity = +<br>
Back End Active = 540<br>
Front End Ative = 1080<br>
Refresh Rate = 30.026Hz<br>
<br>Which I interpreted as Modeline "1920x1080-HD" 74.250 1920 2008 2056 2200 1080 1084 1094 1124 Interlace +vsync +hsync<br><br>
To furthe complicate things I tried running PowerStrip and this is what it spit out for a Modeline(seemed to be identical for both 1920x1080 and 1768x992):<br><br>"1920x1080" 74.250 1920 2008 2052 2200 1080 1084 1094 1125 interlace +hsync +vsync
<br><br>As you can see the last two are pretty close, only off by a couple digits. However, none of the modes I have tried have worked. For some reason when Linux reads the EDID it only reports back the 720x480 and 640x480 as valid modes, which both work. When I try and run the higher modes all I get is a black screen. The log file does say the Mode "X" was validated but I must have something wrong somewhere as I just keep getting the black screen. :(
<br><br>Here's part of my xorg.conf file. I have played with various "Options", you can see some of them in there. <br><br>Section "Monitor"<br> # HorizSync source: edid, VertRefresh source: edid

xorg.conf. I find it rather confusing at times. :-P<br><br>Thanks in advance for any insight.<br><br>Kevin<br>
