Hello Toastyx and congratullations for you awesome application. Also hello everybody.
This is the first time i will write here, english is not my native language but i think we'll can understand perfectly.
Ok, this is my Issue:
I purchased a Sony Bravia KD-55XE9005 (US equivalent is x900e) 8 days ago. Also i have a computer with 2x gtx 1080ti connected in SLI. Both devices (VGA and TV) support succesfully HDMI 2.0 and i can completely use the 600mhz pixel clock rate bandwitdh to create custom resolutions: 1920x1080 120hz, 2560x1440 and even 2880x1620 120hz (i cannot overpass this last because i would pass the 600mhz limit).
here's some pics from imgur since i don't know how to post images here:

I created them from nvcontrol panel but also i have tested them in CRU and it works.
So...
The problem is pixelation or no subpixel rendering when i use 120hz resolution.
You will see it clearly with these pics:

As you can see, the words looks pixelated, but in games is even worse, no matter use AA or MSAA, the images look edged and jagged. All this happens when i use game mode or graphics mode. I do this because 4k 60hz with motion flow On generates imput lag making games unplayable, so my idea was basically have a clear 120hz resolution with DSR enabled.
I have tested all i know: disable SLI, test all HDMI imputs, update AndroidTV firmware (i think 99% is how the TV doesn't interpretate the 120hz input as a 1080p native resolution)... what i've not tested is a displayport to hdmi conversor (until i know 1080ti has DP 1.4 and hdmi 2.0 outputs) but adapters i have seen only support dp 1.2 to hdmi 2.0 (included accell).
Sometimes changing from 60hz to 120hz, i achieve the image doesn't look pixelated but when i enter into a game or something, that switch to fullscreen makes the image pixelated again.
So... i'm out of ideas, maybe it has to do with Front porch, sync witdh, polarity, but is a world to discover. And i'm supposing my cable is ok because i succesfully can do 4k 60hz 4:4:4.
Any help or idea you can provide is wellcome. Someone with this model who had had the same problem and successfully solved it please help!
Also i can confirm this TV model can do more than 1080p 120hz.
Thanks!
