I often walk into the gym to get the rowers set up for my class, only to find that many of the dampers are set all the way up to 10. This always amazes me because I know what a slog rowing at a 10 can be. I understand that people don't always know better and often treat a damper setting like resistance. They think, "If I set this thing at a 10, it will make me work harder and I'll get a tougher workout, and that will make me a badass." You will have a tough workout, and quite possibly a miserable experience and a backache to boot. Understanding what the damper actually does for you will allow you to row more efficiently and create a more "enjoyable" experience on the erg.
Damper 101 First of all, damper setting is NOT resistance. The damper setting creates a drag (allows more or less air into the flywheel). It gives you the feel of a heavier boat or a lighter boat. To move both types of boats quickly, you have to put more energy into the system. If you want to move a lighter boat quickly, you must row faster or harder. However, if you just paddle along, even a light boat will go slower. It all depends on how much energy you put into the oars. Imagine a sleek, one person racing boat. The faster you move the oars through the water, the faster you will go. The same principle applies to the erg. At a lower damper setting (1-3), you will move quickly on the slide, and it is easier to row at higher stroke ratings. Rowing at a low damper means that the flywheel is more closed and less air is able to come in and slow it down. This also means that the flywheel doesn't decelerate as quickly so at the catch, you can continue to move quickly into the next drive without taxing the leg muscles too much. Once again, your pace will be determined by how much pressure you put into your footplate and handle. At a lower damper, you can move faster and rowing at faster stroke rates tends to be more cardiovascularly taxing.
On the flip side, rowing a heavier boat requires more pressure into the oar to move the boat through the water. As with a lighter boat, to move a big boat faster,
you have to row harder. On the erg, rowing at damper settings between 8-10 can feel like
a big, heavy boat. The damper opens up the flywheel allowing more air to circulate, thereby requiring more energy to keep it moving. The flywheel also decelerates quicker, requiring more muscular energy at the catch to get it moving again. This typically
means a slower stroke rate. Rowing at a high damper setting can be more muscularly taxing.
Which one do I do? Damper setting is a very personal preference. You need to row at different dampers to find out where YOU are most efficient. Some questions to ask yourself... Do you like to move faster like a sprinter? Do you like to move slower but pull a heavier load? What type of build do you have? What type of piece are you rowing? In general, smaller people with petite builds seem to have good luck at the lower damper settings. Bigger, taller, more muscular people can often handle a higher damper. I find that rowing somewhere between 4-5 works well for me for all purpose rowing.
For very short pieces or when looking for max power or calories, you may consider bumping
up the damper a notch. It's always good to practice and see where you feel the most
powerful. Try a watt test...row at damper 2 for 30 seconds at heavy pressure and see what
watt output is. (Bodyweight plus is a good thing to shoot for). Rest 30 seconds and try
again at damper 4. Feel any different? Continue up the flyhweel until you get to an 8 or 9.
As you go to a higher damper number, when do your returns begin to diminish? Play around
with it and you will find a damper that seems to give you what you want.

This article is fantastic and I borrowed heavily from it.
For other great videos on Damper setting, check out Shane Farmer's Dark Horse Rowing. He has two videos on damper setting...Part 1 and Part 2.
Here is another great video from UCanRow2 featuring the late, great Terry Smythe on choosing a damper setting. She makes the point that the better you can learn to make a good connection at the catch, the more efficient you can be with your stroke working less hard and with less air flow.
