Speed up HDMI connection on ubuntu 20.04?

cn flag

So I use ubuntu 20.04 on my laptop with external monitor, I use basic HDMI cable ~ not the golden expensive one. Everytime my computer goes to sleep mode, witch make my external monitor goes to sleep/black screen too, when I press a key my laptop woken up fast, but my monitor will take roughly 2 seconds, witch is annoy me so much.

Is there any thing that I could do to speed up my HDMI connection? Should I go buy some expensive cable? Is it helping?

Note that I use cheap monitor 24" Phillips IPS ($150)

No and a different cable won't change anything. This is how the monitor works.

Thanks, you should write an answer for that and I'll accept it.

Someone in the comments already said it: that the cable quality is not going to help it's that the monitor is just taking time to wake back up.

You could consider setting your laptop to take a bit longer to blank out / shut off the monitor - I don't have an Ubuntu desktop sitting right in front of me at the moment (I mostly use server) but I'm sure there's a setting

The other thing you can look at is to poke at your monitor - it may be possible to have it not shut down/sleep when it gets no signal - this would use more electricity but if things are just timing out a bit too quickly, it could help

EDIT: corrected "big longer" to "bit longer"

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.
