You can get another account at an online site that will keep your hundreds of listings up continuously for free. Shop around. Some will import from eBay, the photos and all. So once you listed items here, they'd automatically be ported over to the new place and be there until sold, and here until they expire, sell or you end them. You can import them back to eBay whenever you want (if they don't sell at the other site). You wouldn't have to change anything.
For the monitors: I'm not saying OP should "leave eBay"... just that there are other sites similar to eBay that will keep the listings up, free of charge, until sold. The OP can use both sites, do less work overall, and be much more successful.
