Narrative:

First leg of a two-day. Den ground us gave clearance to follow the third of three aircraft coming from our right and taxiing to runway 17L. Ground control also added that we would hold short of the 17R hold short line on ed. We acknowledged and understood this guidance. I have never had to hold short of the 17R hold short line on ed and wanted to make sure I knew exactly where it was. This part of ed is on a hill. It rises as you approach from this direction and drops off in the vicinity of 17R. I wasn't certain where the hold short line lay with regard to the line of sight we had. In an effort to see this area of the 10-9 page more clearly; I expanded it on the efb. As I tried to center my point of interest; the efb page cycled to the 10-7 page (the first page of the pages I had selected). It took approximately three attempts to reselect the 10-9 page. At this time; I noticed the hold short line going past us and den ground control called and told us to stop. We complied. Ground control informed us that tower had sent an aircraft around. We acknowledged. Ground control then stated that if we did not expedite; they may have to send another aircraft around. We ensured that we were now cleared to resume taxiing and complied. Preventative measure: 1. I could have informed the pilot flying that I had never held short of 17R at this location and was not 100% certain of its exact location. This might have generated a more detailed discussion of our plan and more cautious approach to the hold short line. 2. Ground control; in the interest of safety; could also state that this area is one of the airport's known hot spots for deviations. 3. I'm not sure what other signage/lights they could install to show this hold short line; but it might prevent this from occurring again. There is not a large runway in front of you in which to hold short. It's the same taxiway you use every day. In seven years; I've never received this clearance so I suspect it is not that common. 4. Obviously looking outside is a good thing most times. I could have made an earlier shift from attempting to get the 10-9 page back on the efb to looking outside for the hold short line. However; signage being what it is in some locations; there are times that the 10-9 has saved me where looking at the signage would not have. This may have been one of them had I not accidentally cycled off the 10-9 while trying to center the point of interest; this is part of learning to manipulate the new efb and its potential limitations/gotchas.

Title: An air carrier crew following a line of three aircraft was issued a hold short of DEN Runway 17R at ED. While the First Officer was having difficulty locating the Hold Point on his EFB; the Captain crossed ED because the preceding aircraft; unknown to him; were not issued the same hold short.
