I was seeing some weird issue with ADV7511w chip. I was able to drive the hdmi tx with 1080p,720p,vga resolutions for dell monitor. Some times PLL is not getting locked. multiple stop and run with helps to get working. what could be issue ?
One more issue is - when i use the NEC multisync monitor(4K or FHD) it doesn't even detect the input video for 1280x720@60fps/620x480@60fps. which works fine with dell monitors, can you please point me where i can look inot to fix this issue ?
