I apologize in advance if this is not the right place to post this question but any kind of help or direction would be very helpful as I've tried all my possible solutions.

My machine is a Dell XPS 9570. I was running Windows and Ubuntu in dual-boot and everything was great. At a certain point, the HDMI output stopped working on the windows side, I'm still able to detect the dedicated GPU and the monitor from the HDMI cable but there is no output. enter image description here

On Ubuntu, everything works fine, both from a USB drive and also from the partition.

I believed that the problem was in Windows and I performed a clean install of windows/intel and Nvidia drivers. Nothing worked.

On the Nvidia control panel I don't have access to the Display settings tab: enter image description here

I tried disabling the intel driver to see if Windows picks up the Nvidia card but it defaults to Windows basic display driver.

I even tried on a different SSD, with a fresh install of Windows, and still nothing.

I remember that a while ago I disabled the GPU in Ubuntu because I was not using it and I was trying to gain a bit of battery savings... I don't remember the steps I took, Is there a way to restore everything to default?

Again Any kind of help or guidance would be greatly appreciated as I don't know what to do.

Thanks a lot for your help and expertise!

If it works in Ubuntu and not in Windows why exactly are you asking here? Windows is off-topic here. You may want to post at superuser.com.

Thanks for your answer @ChanganAuto, I posted here because I think I messed it up from the Ubuntu side. I will try there as well though thanks

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
