I don't buy TVs but I quized the guy pretty heavily thinking that was an option. He seemed to know what he was talking about about. This was an Onn Roku TV.

Where I first caught wind of this was in the return line at Walmart where a guy was returning a smart TV because he wanted to hook up to his Dish receiver and couldn't without creating an account.

Great info. I think the screen is easier. Thanks for this.

There are some amazing projectors available these days and they don't seem to be crippled by smartification. There are some cool homebuilt projectors that are made of bright light sources and old cell phone screens to, if you want to learn.

Some smart TVs require you to connect them to the Internet before you can even use them with HDMI. It's a changing world. This post has a lot of interesting comments.

Yeah, I think newer panels are probably MIPI DSI but there are cheap controller boards for that too. I don't think I will do this as I really don't have a need.

A previous, now deleted post sent me down this rabbit hole. I also understand why the OP deleted it. There are a lot of professional unboxers here who get upset with the idea of building anything.

I don't trust them, especially after this incognito finding. I use them to encrypt on unencrypted wifi. That's all I trust it for.

I use Google One VPN which also promises not to keep my data. Hahahahaha

Seems like this would be a good place to get rid of those end-of-life A10s.

The reason I like Gray Jay is that it is source agnostic, so you can still use YouTube (because that is where the content is now) while also using other sources.

I would like to see videos posted to ipfs.

But still getting off of YouTube as the source, right?

Do I understand you correctly?

I think you will need a power supply for your panel in addition to a driver board like this. This only provides the signals needed to switch the pixels but not the power to drive them. Some of these include backlight drivers but even then I think you would probably need more current for a TV than these provide.

I retired from embedded systems design and design-for-manufacture a decade ago. Reading datasheets was most of the job. This doesn't look too daunting. It's a single interface between two readymade components. I've identified where some issues might come up, and there are probably some that I don't know about yet. Still this seems less like building a circuit around existing ASICs and more like hooking up stereo equipment to me.

Seems like a fun project to me too. It also seems like things have changed since the turn of the century, with regards to interoperability.

Why did you do it?

On Roku smart TV from Walmart. I was present in the returns line when a customer returned it because he wanted something to use with his Dish Network receiver and this one required he creat an account.

I can think of no better use for a TV

I don't think anyone repairs these things anymore. I found two dumped in the desert, one with its controller and power supply boards removed and one that was complete.

I got interested in this when the previous poster asked the question. Going down the rabbit hole I think I have my answers. Avnet has some good info on the mipi interface for consumer devices. It's been very interesting and I do see it as a path to building good, cheap, large displays.

Or I could just accept my place and watch the ads and go along with all the caveats like a good consumer. I don't see that happening.

It seems like the current standard is MIPI DSI. This is my sourcee of information. I think it is doable.
