Looking for the biggest 12v HDTV out there

Hey folks,

I intend to repro my home theater and man cave and while I'm not apposed to running my huge HDTV from an inverter, I'm just wondering what is the largest 12v HDTV that YOU HAVE??

No theoretical discussions here please - I'm not asking what all could be possible if. . ., just the facts. Have you been able to get a 40", 50" 60" 4k HDTV etc?

Thanks in advance!

    You have that reversed.... Actually we are trying to sell him the superior Coke product.
  • Taking off my Moderator hat for a moment, maybe I can help the OP.

    Can I ask why you're looking for a 12v TV?

    I don't know what your experience level is with RV appliances and I hate to dude-splain, but are you just looking for a TV that will work in your RV or are you hoping to find 12v for a specific reason?

    How familiar are you with inverters? This is an oversimplification, but you can power most household 110 devices with an inverter. The inverter "inverts" (changes) the 12v power from your coach batteries into 110 power. Again, this is an oversimplification, but you basically connect the inverter to your batteries and then plug the device(s) into the inverter. This lets you run a regular residential TV from your 12v coach batteries.

    If that addresses your question, then there are a bunch of follow-up issues to deal with. What other devices do you want to connect? What type of appliances are they and do they have specific power requirements (modified sine wave, pure sine, etc.) How large are your house batteries? And on and on.

    I hope this helps. It isn't the solution to your question, but hopefully it's a good starting point.

    Apologies again for the unfriendly replies.

    Yes. Totally your fault. Stop trolling the New Members.
  • Did any of you happen to notice that the OP is a New Member? Is this how you treat new members?

    How embarrassing.

    I deleted all the off-topic troll responses.

    Hopefully the OP returns and we can actually have a conversation.

    You guys that are bad mouthing 12 volt TVs. Most all TVs on the market today have a wall wort, If you look at that wall wort you will see that it's output is 12 volt.
    My old tv with the 12v brick was actually 12.6 volts IIRC. Screen would get scary bright at 14.4 boost charging the battery and the tv would give a beep tone when the furnace etc would pull the voltage below 12.4 volts. It was a great idea in theory but impractical for actual use.

    300 watt sine wave inverter was the solution to work in all conditions. Sine wave also solved the lines on the screen when using a square wave inverter.
  • Generally, "12V" appliances tend to cost more and have less quality.

    Case in point the 40" Jensen (RV substandard quality) brand TV in the link Itenerant1 provided will cost you $453 and Jensen has a lousy reputation for quality (it is just a name from the 1950s that used to mean quality)..

    You can get a 120V Sceptre 40" Class FHD (1080P) for $250, VIZIO D-Series 40” Class Smart TV for $349, Samsung 40" $380 and so on..

    The small amount of power used by the inverter is pretty insignificant and really not worth trying to eliminate with a cheaper 12V quality TV..
