Its etm0700g0dh6 vs. et070080dh6, Philipp's panel is with captive multi touch, (hence the M I guess). The panel itself really looks the same. I found this overview of EDT displays: http://www.dmbtechnics.com/scripts/passthru.php?id=7 There seem to be quite a lot variants with the same panel... Regarding timings, I just checked the documentation, Philipp's timing really matches the documented ones, I miscalculated the vertical back porch. How do we resolve that? I would suggest that I split out that patch and remove the et070080dh6 panel and send the other as a single patch to the dri-devel mailing list as well. Philipp, could you add my display type (et070080dh6) to the compatible list of your mode/panel entry? Does this sound reasonable? -- Stefan
