[SOLVED] How am I getting 4k 60Hz on my 1080p TV when it only has HDMI 1.4a ports using Nvidia Custom resolution?

[cronik93]

I have a GTX 1080 which has an HDMI 2.0b port and I'm using a HDMI 2.1 cable but the HDMI 1.4a ports on my TV limits the bandwidth to the HDMI 1.4 specification. HDMI 1.4 only goes up to 4k 30Hz. As I said in the title I'm using Nvidia custom resolution.

This is my TV: TCL 32" Class 3-Series FHD LED Roku Smart TV - 32S327 | TCL USA

is a 1080p tv, it not going to get 4k
are you using dsr? it just render in 4k then downscale back to 1080p

You're not. Whatever is telling you you're running at 4k/60 is incorrect. Or maybe your device is attempting to output at 4k/60 but 100% chance thats not what the TV is running at. If you have Nvidia custom set then its maybe rendering at 4k/60 but its downscaling before output to the HDMI port.
