This is a windows bug. Are you still on win10? It's fixed in 11.

It's mind-boggling to me that this hasn't been fixed (in Windows, I assume?), people have been complaining for years.
It's not inherent to DisplayPort though. Some monitors that suffer from this issue can disable "deep sleep" and have the issue gone even with DisplayPort, but not all monitors allow turning it off.
(And others yet, like my old Acer XB271HU, doesn't have the issue to begin with.)

Works on Linux (gnome)

If only VGA had 4K@120+ fps support...

From the transcript and ai generated summary from Claude:

Here is a summary of the key points from the Linus Tech Tips YouTube video on why DisplayPort is better than HDMI:

• DisplayPort has an embedded mode (EDP) used in laptops and tablets to drive internal displays in a simpler, thinner way vs HDMI.

• DisplayPort has a USB-C alt mode to deliver signals over USB-C ports, enabling charging and video over one cable. HDMI's alt mode was discontinued.

• DisplayPort is royalty-free while HDMI charges device makers a per-unit royalty fee.

• DisplayPort supports multi-stream transport for daisy chaining multiple monitors from one output.

• DisplayPort can easily convert to HDMI signals via passive adapters, but not the reverse.

• DisplayPort cables often have latches to lock them in place, preventing accidental disconnections.

• Key advantages of DisplayPort are higher bandwidth, more flexibility, lower costs, and convenience features over HDMI. But HDMI remains widely used due to broader consumer electronics adoption.

In summary, the video makes the case that DisplayPort is technically superior to HDMI in several ways, though market dominance of HDMI persists. Both serve an important role in connectivity.

I simply cannot stand LTT. I wish there was a TLDW bot on lemmy. I've seen it in a couple of posts.

On a <5 minute video?

DP has embedded, can be carried over USB-C, allowing for everything to be handled over a single cable, is handled on connector instead of device-internal interface allowing for smaller/thinner devices, DP daisy-chaining, licensing/royalty differences, etc.

That's not really an issue with DP itself, but with the operating system handling unplugging, if you allow me to be pedantic.

How would you want that to be handled? The monitor is removed from the system. Do you want a phantom monitor to remain in place, with applications and desktop, no longer accessible?

That thumbnail formatting style is disgusting but they keep doing because I guess it works.

He doesn’t look shocked, why would I click on that?

He's pointing and using a red arrow.

Man clearly knows his stuff.
