We're planning to upgrade the TV in our motorhome, but the problem I'm seeing is that the newer TVs won't fit. I could order a large computer monitor that would fit and would provide what we want, but the input to that monitor is just HDMI.We have two coax inputs now, one from an over-the-air antenna, and one for "cable" (for when the RV park has a cable TV connection). These both come to a switch box at the front of the motorhome, about 15 feet from the TV set. From there the signal goes over coax to the TV compartment.I have a good location for the new TV that would actually be better than the original and I could route an HDMI cable from the old switch cabinet to the new TV (computer monitor), but I don't know how to convert the input signals to HDMI. I think I can deal with the over-the-air signal, but I'm not sure about the cable connection. With the present set-up, the TV has to be switched from "air" to "cable" to tune in the cable channels, and the computer monitor won't have that function.

Not sure how a new computer monitor will fit where a new tv in all the various sizes won’t but you’ve done the looking. I’ve seen on here where after removing the old TV, folks have turned that big hole into a storage area with a hinged piece of wood for a door and mounted a new flat screen on the door. Many new TV’s, esp the higher def ones don’t have coax either. There are boxes you can buy that will adapt the coax output to HDMI output not sure how well they work.

A computer monitor has no tuner, so you would have to buy an external converter box. Most of these boxes only work for digital signals. This would work fine for antenna and some digital cable. It would not work for analog cable TV which some parks use.Here's a box available at Walmart:https://www.walmart.com/ip/Ematic-AT102-Digital-TV-HD-Converter-Box-with-LED-Display-and-Recording-Capabilities/54655846As mentioned, it's a puzzle why a TV would not work.

You will be miles ahead by finding a TV to fit. It does not necessarily need to fit inside the hole. The new flat screens are so thin that they can be mounted such that it overlaps the frames around the old TV. There are many examples of this kinds of modifications available if you do a bit of searching. Even if the box is square and the TV is rectangular, that's a great extra space to mount a sound bar and really enjoy the TV/Movies experience.

To answer questions raised, the TV is presently an older flat screen located on a section of wall that's just wide enough for the TV. The opening is 32 inches wide, and there's not much room for something wider. One edge abuts the driver side wall, and the other edge abuts the hallway. Most wall space in the living area is dedicated to windows.I was hoping for UHD, but TVs don't seem to come with UHD that small. (I've only found one computer monitor with UHD that wide--most are smaller.)

You will see only UHD when using a UHD Blu-ray player and UHD discThere are no UHD broadcastsAnd any UHD web stream is going to eat massive amounts of cellular dataHave you considered all of this

A slight modification may help it fit. You just need one of these. Color doesn't matter:

I don't know why you can't find a new set that will work in the space you have available, we have sets in the RV and in the S&B that range from 7" to 43". The two in the RV are both HD and we have two Blu-Ray players. Both sets are wired to the BOMB with coax and we have no problems. In our old rig we wanted to show the same movie from one Blu-Ray player so I ran a cable from the front to the bedroom. I had to install a splitter at the player and it required 120vac to operate. No biggy.

Being a little creative is necessary but if you don't want to do the installation there are techs all over who will do it for you. Both the CRT sets in our rig have been removed and one space is just blocked off with a piece of plywood with veneer that matches the cabinets and the other I converted to a storage area and shelf for the Blu-Ray player.

I do the same, except I have no UHD discs
As my player and tv are not UHD
My BD player is 3D
Unfortunately, nobody is now Mfg 3D tv's, at last not for mainstream consumer sales

Thanks, MrWizard, and I understand this, but we do have a blue-ray player, and I'd like to get a UHD picture when we watch the discs. We really don't watch a lot of TV, either broadcast or cable, but we do watch the movies we have (and we've got hundreds). We buy them second hand and try to focus on ones we'll enjoy more than once.
