In the other thread he mentioned a burst mode and setting the DSI speeds to higher frequencies, but the patch he had didn't look like it would apply cleanly, so I will need to dig into that a bit further. Since my company doesn't really ship the LVDS displays with the kits, the HDMI is the default video, so I've been focusing on it. To answer Marco's question, I was able to revert "MLK-21958-13: drm/bridge: adv7511: Limit supported clocks" and still get a display at 1080p, but all the other resolutions I tried appear to come up blank. I didn't try every one. With that revert, more options come available, but 1440x900 and 800x600 were options I tried unsuccessfullyl. adam
