Thanks for the replies, the problem is, I can't find specs beyond: supports 1920x1080i and 720x480 and vertical refresh of 59.94.
If I have this working modeline, can't I reverse the math the modeline generators do and find the specs? Also, the EDID info from the TV (in Xorg.0.log) said the following: VertSync: 59 - 61 HorizSync: 15 - 34 Many of the modelines I try say "VertSync out of range", then later say that that modeline is not found. If I turn off DDC, EDID, DPMS, the out of range error goes away, but the modeline still shows up as not found. For those interested, here is the "quick" method I use for messing with modelines: -In Xorg.conf, I have my "good" 720x480 modeline as the second one in the list of the "Screen" section. -The first one in the list is called "Test" -I then paste any modelines I want to play with into the "Monitor" section and rename the one I want to try to "Test". I issue "init 3 && init 5" from terminal window (restarting X) If the new modeline doesn't work, it defaults to the second in the list, which is my "good" modeline. If it works but is crazy refresh or anything else wacky, I simply issue "xrandr -s 1" from a terminal window and it switches to the good one. Its quick and convenient, but its still not getting me where I need to be!!! Anyone have an idea as to whether I can use a different DVI-equipped Windows PC to test my modelines, or must it be with the videocard from the Mythbox?
