EDIT: This is now solved thanks to @Amarok! Solution is here. Changing the refresh rate from 60 Hz to 120 Hz fixed it.

My husband and I recently upgraded our TV to a Samsung Q70, and I have started experiencing an odd issue, visible in this video here.

The Issue

There's a horizontal section across the entire bottom of the screen that seems to be refreshing later than the rest of the TV. The game is running on a PC hooked up to the TV via HDMI, and the TV is running on game mode. This issue did not happen on our last TV (a 10-year-old Visio that I don't remember the model number of).

The Oddness

• It doesn't happen on the desktop or in video inputs.

We've been watching YouTube and Hulu through a Shield TV that we also have hooked up, and this issue isn't present in any of those, nor is it visible when I'm using desktop applications on the TV through the PC.

• It only happens in certain games.

The video is from Trackmania 2: Lagoon, where it is always present. Meanwhile, it is not present at all in Trackmania (2020). Likewise, I've been playing 428 Shibuya Scramble where it shows up in the exact same way in the exact same area, but it does not exist in Distance or Rogue Legacy, for example.

• It does not respond to v-sync.

I've tried toggling v-sync on and off, both through the game itself and forcing it through my video card. Neither alleviated the issue. The display looked the same whether or not v-sync was turned on or off.

I'm looking for any guidance anyone can give me, especially if this is a hardware issue with the TV itself, since I'm still in the return window.

This submission showed up on /r/listentothis a couple of weeks ago. I'm reposting it here because it is the finest and most on-point collection of music I have ever encountered. The original post from /u/theamazingsounds is included below.

Hello again fellow music enthusiasts!

1 year ago, I made a post about my ongoing project to create a collection with as many genres as possible, aiming to give listeners a convenient way to discover new music. It got many interested and since then more than 50 genres have been added, as well as descriptions for every genre.

I'm making this post to thank those following already, and am once again open for suggestions and ideas. I also made a subreddit called r/TheAmazingSounds where you can post about music that you want to share with others. It is currently empty but I will try to keep it active and reply often.

You can find everything on Spotify. It is synced with other services but doesn't convert all songs.

Note: I don't love my title and am open to any community edits that improve it!

"Really big deal" is of course relative, and it doesn't have to be a big deal for everyone but can be big for a specific domain, field, or group of people. It also dosn't have to be recent. Many "big deals" of the past have yielded things that are largely invisible to us now and that we take for granted.

What is something that is hugely significant but also seems to have no common presence in current discussions or understandings of the world?
