Seiki SE50UY04 3840x2160 50" TV ($1300)

Cool, keep us updated! If you get 4K 120 Hz to work I'll be one of the first to buy.

Well covered a few Seiki's to drawing machines...Full Presure sensitivity with drawing pen..Awesome in Photoshop in 4K

I built many old time drawing machines and building a 50" and a 42" now..ut it takes a lot of guts to rip these things apart.. must be stripped down completely down to the backlight lens..

Thanks woodguy32

That's really cool, what was your touch solution?
 
As an update, the FPGA firmware is now (mostly) working in simulation. There are some remaining to-do items(aren't there always! haha), but there is significant progress despite the lack of recent update posts.
Anything happen in the last two weeks? I've been following this thread closely and I can say it would be a real shame to see another hopeful project get dropped!

I've submitted the design to an FPGA professional with lots of experience with the chip family that is being used. Once he OKs the design, I'll send the hardware out for manufacturing.

That's awesome. Thanks for your response!

You got my order waiting.
 
Boards have been ordered. Should have hardware to test with in about 1.5 weeks.
Stuff like that has caused me to be 'too careful' in the past. If I just dove in and did things, I would have sold a lot more 240Hz monitors.

Boards? Is this multiple prototypes or a production run already?

Minimum 10x qty from pcb fab house. Will assemble 3x for testing. Using only one for prototyping is just asking for a hardware glitch/failure to ruin your week.
 
I'd be excited too, but it is difficult when the fpgas (and other parts) have been stuck in customs for 3 weeks :(

edit: After three weeks delay in customs (and some in shipping too!), the components have finally cleared. Should have assembled boards in ~1-1.5 weeks.

Never was a green light so welcomed [H]ere.
Soon enough the first 4k panel to reach mass market prices will also become the first 4k 120Hz panel.
 
hahaha no smoke is a good sign!

If this is successful....which Seiki Models would be best? I have the old 39" VA model.....Also, I think it was mentioned that a 28" TN panel option was out there.....any other displays?
 
Now that's what I call progress!
I've been watching this thread like a hawk since you started cirthix, and dayuuuuum is it ever starting to get interesting! :D
 
Fixed a few minor hardware issues, found some minor firmware bugs. almost ready to plug it into a panel.

Whatever is a non TN panel wins my vote!

120hz 4K non TN is basically my dream.

In a TV sized panel... the complete dream!

most 4ch LVDS panels with conventional connectors are theoretically compatible with this solution, but this firmware was created for the Seiki 39", which is one of the few native 120Hz 4k panels widely available.

check panel database for the panel PN, if it says 4ch LVDS, there is a chance.

No, this is misinformation. It is the panel-side connection that matters, not the input side.

The panels that I'm 100% sure that it will work on are: M280DGJ*, V390DK*, V420DK*. The other previously listed panels may work, but it is designed for these these primarily.

Also, it is not strictly desgined for the seiki. The seiki just happens to use the V390DK1 panel.

Thanks for the clarification guys. I've been under the impression the mod was specifically for the 50' Seiki.

It will very probably fit the V500DK2 as well as the V580DK2, but I have not fully verified tcon swap capability between those models yet (and I don't have the voltage measurements from them either). I only have the 39" and the 28" to test with.
 
In the future, it is relevant that the solution can be used with a panel that is still in production, like the V400DK1, the smallest 120Hz 4k panel in production according to panelook.com.

Out of curiosity, the V390DK1 was the smallest 4k 120hz panel ever built and a natural recipient of such board. there is only one 4k panel with faster in-spec refresh rate, the AUO T650QV a 65" 240Hz beast. i wonder what can be done with V-by-one 16 lanes, 104 pins?:LOL:
 
Now testing the board with the panel connected. Attempting to display a test pattern first.

The first test resulted in a gray screen. Better than an all-black screen :).

if all that is needed for voltage testing is your average $50 multimeter, given a little bit of instruction, i can provide data for the 50' w/out the tcon swap.

Not the intended test image, but I can see how it differs. Getting closer!

The image is stable, so most of the system is functional here.
