Specifically for TVs, you can get a new display driver board for whatever panel is in there. Eats HDMI/DP, spits out eDP or VBO or whatever the panel format is. Often these are pretty basic, with a minimal OSD pasted in by the Shenzhen seller who configures the thing to your order.
Personally I'm trying to get my hands on the SDK for the software that runs in the driver chip (does the OSD and the scaling and everything else), because I think there's a lot of potential there. But boy it's like pulling teeth.
Similarly, the Exploiteers (née GTVHacker) have done quite a bit of reverse-engineering of the stock boards, so you can just fix the broken-ass firmware they ship with.
Ultimately I'm picturing something like the WRT54G, a single modem that the community coalesces around, to the point that a decade later, third-party firmwares have become such a force that manufacturers build hardware specifically to run it.
- nitrogen 6y agoNice. Do any of those support 100+Hz frame rate or Freesync?

- DaiPlusPlus 6y agoHDCP strippers are a thing now, so this shouldn’t be a concern.
- MaxBarraclough 6y agoFor 4K? And are they legal?
- jiggawatts 6y ago> Specifically for TVs, you can get a new display driver board for whatever panel is in there. Is this something that is practical and commonly done, or only theoretically possible? I have an older model Sony 4K TV (pre-Android) that is so slow now after its recent firmware updates that it responds to button presses only after 2-3 seconds. It's unbearable! I'd love to be able to just pop in a new driver board and refresh the TV, but I've never heard of anyone doing this kind of thing before.
- myself248 6y agoGet the part number of the panel (some reviews will mention this, if you don't want to open the case), and search for it on Panelook and Aliexpress. Right now I'm working on a project with some M315DJJ-K30 and MV238QUM-N20 panels, but parts are still in shipping so I don't have anything to show for it yet.
- ce4 6y agoAny pointers to forums/projects or sellers of these? Sounds like a bit of a rabbit hole, tbh :-)
- ce4 6y agoI found this for the Realtek rtd2556 chip which there are plenty of boards for on ebay when you search for edp+hdmi+converter: https://github.com/ghent360/RTD-2660-Programmer https://github.com/ghent360/RTD-2660-Programmer
- myself248 6y agoThese guys are doing it somewhat commercially: http://zisworks.com/ http://zisworks.com/ I've stumbled into a pile of panels and I have several orders of different driver boards on their way to me from Shenzhen, but nothing in-hand to say if they work yet.
