TV upgrade: 12V or 120V

We will be changing our old tube TVs this year for flat screen, I just assumed we would go with a mid 30 inch 120v regular unit but now am wondering if there are any reasons I should consider 12v. We will likely watch downloaded movies and shows or drag out the dvd collection. Thoughts?
We are weekenders and short trips as we are new to this adventure

My 32” LED TV will uses $12/year of power. You will need 120V power to play your recorded videos so I would not worry about a 12V TV.

A LED TV is thin enough that I mount them on the face of the cabinet, not in it.

Have not seen any 12 volt 30" TV's in flat screens, not sure if they are available, if so probably not affordable, IMHO 120 volt is the choice.

Rushy,
We just went through all of what you're thinking of a few months ago. It's a long story but, in short, our coach, is an '04 Itasca Horizon 36GD with the CAT C-7 330HP and, both TVs, were seriously outdated. The front one, was a SERIOUSLY HEAVY boat anchor Sony. The bedroom one, was just a smaller boat anchor. In the searching for a close fit to the cabinetry, I found a Samsung 32" LED TV. The original Sony weight right at 108 lbs. The new Samsung, is a whopping 8 lbs.

I have no idea what the original Sony required in operational electricity but, I'd bet my stick and brick house the new Samsung is LIGHT YEARS ahead of that old unit and requires probably less than a tenth of the juice that the Sony required.

Yes, both of those new TVs we installed do require 120VAC but, it's a seriously reduced amount of AC which, is provided by an inverter if and when we need it. I also installed a new Blue Ray DVD unit at the same time. Our new system is so, SO MUCH better in terms of quality of TV, application, picture, color and more. And, I don't have use one of ding-a-ling digital converter boxes any more. This new TV brings in, along with my "antique" over the air antenna.

I bought a 12 volt TV for a 2nd TV for the front of my rig. It can be powered from either 12 VDC or 120 VAC. Since I have a 12 volt house battery accessory outlet right near where the TV is mounted, I use 12 volts. My TV is 24 inch and has a build in DVD player. It is very lightweight and I can easily un-mount it and take it outside where I can use a 12 volt power pack with a coax extension. I believe it takes less than 2 amps from my batteries. Quality is good, but not fantastic. I'm not a huge watcher of TV.... just want to catch the news or watch a Netflix movie on the rainy days. It is not a smart TV. https://www.amazon.com/TVD1801-24-24...tronics&sr=1-2

Do you often dry camp? This could be a reason to go with a 12vdc appliance. Avoids the power loss effeciency of a inverter. But the cost and product selection limitation vs the small gain in effeciency is hard to justify. Imho.

If you dint dry camp, I see no reason.

12V TVs or more correctly 12V only TVs are some of the cheapest and worst pictures around. Go look at the power brick that many TVs use. You will find they are a step down transformer. Pick what you like.

Keep things standard and affordable with 120vac equipment and use an inverter for running things off the grid.
Easy install if you plug the shore power cord into it and after shutting off all, but the low power essentials, which would include the entertainment system.
I did it the hard way, with our old gasser and ran outlets here and there, to include the fridge. A lot better that way, but it does take some work, besides having to manually control the load.

Our 5er came with a 12VDC TV in the bedroom. Pure junk! Poor picture, worse sound. It has been replaced by a 120VAC Vizio. But with that said, if you boondock and really have to have TV and don't have solar w/2-4 batteries and an inverter or a genset, do your homework and you just may find one that works for your needs

Kinda pricey and then if it fails, it's doing for doing it, all over again.
I can buy two for that price or pay for a pretty good MSW inverter and have money left over.

Just get a good quality 120VAC TV and you'll be fine!

If there is a 12V outlet near where you want to operate a TV, all you need is a 150 watt portable inverter to run a 120V TV. We have run both a flat screen TV and DVD/VCR player at the same time with one in our previous RV.
