I'm running a 21.5" Samsung: http://www.amazon.com/Samsung-21-5-Inch-HDTV-Monitor-T22C350ND/dp/B00IEZGW4Q/ref=sr_1_1?ie=UTF8&qid=1408942550&sr=8-1&keywords=T22C350ND which may still be carried by Costco. It took a little web searching to find the right DC plug, but I got one on eBay for under $5. Generally any of the TV's with the wall-wart power supplies - even those that say "14v" will work down to below 11 volts. There are many threads on here that talk about it. I would avoid an inverter if you can, they're not 100% efficient and their 110v output voltage is often not a clean sine wave unless you pay big bucks for a premium unit. I would not pay a 2X premium for a "12v TV" from the company that makes very low-end stereos for RVs.
