Would it be possible to position the custom resolution in a specific area of the screen? For e.g, a ultra widescreen image (32:9) in a 4k tv, but rendering the image only on the lower part of the screen.

I used to do something similar with an ancient program (Powerstrip) and only via analog output, digital doesn't seem to work

The only other option is to get the full EDID from somewhere else, such as Linux or an AMD card, and then import it into CRU, or you can delete the extension blocks and manually add what you need.

Currently my PC is connected via HDMI to my TV which in turn is connected to a Sonos system ( still in HDMI). The issue is the PC won't send 5.1 sound to the TV because it can't detect the sonos system and its support for 5.1.
While i understand there are no specific features that address this issue i was thinking adding support for hdmi bittstreaming could do the trick ?
Simply setting the LPCM format to 8 channels should be enough unless you want all the bitstreaming formats.

No, you can only center the image.

This laptop can be configured with a 4K screen @ 60hz, and even 10 bit (8+2 dithering) depth. This approximately required 4x the bandwidth as there are as 4x as many pixels in my understanding. So theoretically the interface should be able to do 4x60=240hz (i know i don't calculate the timings here but it's to get my point through). If i were to guess the interface is the latest eDP v1.4b which has more than enough bandwidth to do 1080p@120hz for example. Isn't the pixel clock rate related to the bandwidth of the interface? Why there is a 240mhz limit? If it was different how come normal DP (which eDP is based of) can run past that limit and clock patcher is available? :/
The panel is not going to have the interface to support the bandwidth required for a higher resolution that it doesn't support. DisplayPort runs at fixed clock speeds with 1, 2, or 4 lanes. 2 lanes @ 270 MHz (HBR) or 1 lane @ 540 MHz (HBR2) would allow up to 240 MHz pixel clock with 6-bit color and 180 MHz with 8-bit color, which is enough for 1920x1080 @ 60 Hz. The patchers cannot change the clock speeds for DisplayPort.
Thank you, i understand this, but how can the same laptop be configured with a 4K screen @60Hz with the same interface!??

Just because the laptop has the interface doesn't mean the panel does.

Cool, the latter is working. I also tried booting into Windows PE and using CRU to dump the EDID that way, but even without an NVIDIA driver active it was still showing the exact same things
Deleting the blank extensions and adding a DisplayID block worked. Thanks!

I don't understand you. This has nothing to do with the panel, same laptop can be configured with either 4k or 1080p panel at 60fps. Both use eDP interface.

If the laptop is capable of 4 lanes but the panel only has 2 lanes, then it can only transmit 2 lanes.

Ok thank you, this makes perfect sense now
edit: Btw i am able to set the gpu in bios to discrete only, so that only the nvidia gpu is used. Would i be able to patch the pixel clock then and overdrive the 2 lanes available, or it won't work?
edit2: Well i've tested it, set discrete graphics only, adding the resolutions via CRU wouldn't appear, had to set them through custom resolutions in the nvidia control panel, and any resolution above 240mhz pixel clock will freeze the pc with black screen after hitting the test button. Worth noting a couple of point though:
-After successfully testing a custom resolution in the nvidia control panel will increase the pixel clock calculation. So for the same timings, while with CRU i can get to 103hz, with nvidia i can only get to 101/102hz. Weird.
-With the intel graphics any overclocked resolution will report 6-bit colour in the windows display settings, while with nvidia will report 8-bit colour in the windows display settings, but in the nvidia control panel will say 6-bit under the "use nvidia colour settings" but 32 bit in the custom resolutions menu..go figure..
Afterall i guess i should be happy with 60->105hz XD
