How to force 4096 x2160p on native 4k tv @60hz

1. LG.com says the TV is 3840x2160, not 4096x2160. It may accept 4096x2160, but it's probably scaling. Isn't 4096x2160 blurrier than 3840x2160?

no its not blurred at all Apologies for the large picture post I just wanted to show you the text is not blurred.

2. AMD cards are not currently capable of HDMI 2.0 speeds. The latest pixel clock patcher will let you try, but it won't get around hardware limitations.

Yes the damn hdmi 1.4a bandwidth limitation is a pain

3. It's not possible to define 4096x2160 as a detailed resolution because of EDID limitations.

I see, I guess the only way is to wait for a DP to HDMI 2.0 adapter to hit the market.

4. It's possible to add 4096x2160 @ 60 Hz as a TV resolution in the extension block, but AMD's driver will ignore it unless 4096x2160 @ 24 Hz is defined in the HDMI support data block, which CRU does not currently have a way of doing.

Im not using the GPU's to scale the LG IPS panel is scaling and gives me the 4096 x 2160p if I use the gpu to scale i can only get 3200 x 1800 via VSR and that is blurry

Try playing around with 3840x2160 first. Chances are you won't even be able to get 40 Hz. If you can get 3840x2160 @ 60 Hz working, then I can provide a custom extension block with 4096x2160 @ 60 Hz if you want.

I could not get 3840x2160@60 working had to reset. The LG is scaling not the card. that is the problem I belive, but DP 1.2 which is on the card can carry 3840x2160@60hz just have to wait for an adapter.
