I spent all of 5 minutes looking at reviews on Viore TV's. They were all over the place and quite mixed. Some people said they found Viore unresponsive when their TV's died. It is a company that has sold low end TV's in Asia for years and has been breaking into the American market by selling at stores that sell TV's at low prices such as Walmart. I'd rather not take a chance on one. Vizio may be a better choice since they have been getting pretty good ratings lately, but I think their prices have been increasing too. Looking on Amazon, there are some other brands I have never heard of and a lot of Samsungs.
Most of the 19" TV's I've looked at are 720p. This may not make much difference on a small screen TV especially if only used in the bedroom. There are smaller ones that seem to be for cars and would be 12 v. for that reason. Some other smaller ones seem to be for kitchens. In our bedroom, anything larger than 19" is too big. Prices for 19" seem to range from $125 to $300.
The 12 volt
units are more expensive generally. This makes no sense to me since every electronic device operates internally on some other voltage than 120 volts and needs an internal transformer to convert whatever voltage comes in to whatever voltage the device works on. It should cost no more to convert from 120 v. or 12 v. Some 12 volt
TV's come with an adapter for 120 volts. It may be cheaper to buy a 120 volt TV and buy a separate small inverter to plug into the 12 volt
plug when boondocking. I see that CW sells such an inverter. I think it is rated at 400 watts but does not say whether that is 400 watts at 12 volts or 120 volts. It is probably rated at 120 volts, but the catalog does not say. If it were rated at 12 volts that would mean only 40 watts at 120 volts and I doubt there is a TV that would run at that wattage. Details like this are hard to find on the internet, but they matter.
The place to put a mounting bracket in our trailer is on the partition between the bedroom and the shower. The partition is plywood (between 1/2" and 5/8") and there is about an inch of space between it and the shower wall. Airstream tells me 5/8" #10 wood screws work fine. Locking brackets to keep the TV from swinging around while driving are quite expensive (RV prices of course). Some people use a cheaper bracket and bungie in it place. I don't know if a bungie cord would scratch anything, but I have seen no reports on that on the Forum. When we go to CW next week I'll see if they have a good price on one. There were none in the catalog. Prices on brackets on the internet range from around $25 to $109. The high price is for a locking bracket, but there was a review saying it could be gotten at CW at $60 or so—but CW's prices change all the time and that may have been special that has since expired.
A fair number of 19" TV's come with DVD players built in. If you want to put kids in the bedroom to keep them quiet, that is a way to go. There is no place to put a separate DVD player in the bedroom except with lots of exposed wires or nailing it to the wall. Or, a laptop on the floor, but also a pain. If you have kids, they can probably explain how to do that or anything else.
I am torn between many competing values—who needs another TV in a trailer? It would be cool. A 12 TV means I could get TV news and weather when bookdocking. This could cost $400 for the best stuff! Maybe I could get by for $150 (my wife would not allow such cheap stuff, so this option is not available). Meanwhile I look for a wifi booster which could be enough expenses for now, but I can't understand the specs for various wifi boosters. I need to adopt a 9 year old who can explain what to do except they always want to spend the most.
