hi all, i'm using mark iii with external monitor (ikan D5) and am having issuess. basically, it's very wonky. usually, everything will work fine upon starting up intially. but if monitor turns off, and i turn monitor back on, i get no image...or if i go into menu, when i come back out, there is no image--somehow it loses HDMI connection. and then, i have to go through whole rigamarole to get image back--turn off monitor/camera, unplug hdmi, turn monitor/camera on, then plug in HDMI--and then i'll get image. but sometimes that won't work...so i'll have to do all that, take out batt, and then start up again. is this a 5D issue? or is it just my camera/hdmi connection? thanks. goro
