SEIKI 4K 39" HDTV now capable of true 120Hz 1920x1080

Talk about overclocking displays at a higher refresh rate. This includes homebrew, 165Hz, QNIX, Catleap, Overlord Tempest, SEIKI displays, certain HDTVs, and other overclockable displays.

The TV works when I set it to 120 Hz in my PC display properties, but when the TV is shut off and turned back on, I get a blue screen message that says “no support”. I downloaded and installed the latest TV firmware from the Seiki website - even tried the 50" firmware – no change, same problem. Anybody have any ideas? Please help!


Can you provide more details please -- graphics card, graphics drivers, and which Windows version? DVI-to-HDMI cable? Direct HDMI-to-HDMI connection?
I'm using Windows 7, GeForce 9600 GS, latest Nvidia drivers - HDMI to HDMI.

My friend just got one of these and it's not even presenting the option for 120Hz via HDMI. I'm not sure what's wrong...

Because it's not supported out of the box. It needs some manipulations with CRU (and firmware?).

Huh? Every source I could find implied that it should be supported out of the box, but didn't work properly (skipped every other frame).

Well, anyway, it works properly without any CRU fiddling now. We flashed a hacked firmware (not 50") that I found on overclock.net and it seems to have resolved all the problems except for a weird overscan issue when the TV is used with his Playstation3.

I just updated the firmware on my Seiki 39 inch using the custom 50 inch firmware and now I’m able to play my Xbox one X with 120hz.
