MONITOR FLICKERING FIX!!! 

thank u bro, u saved my relationship where my gf's monitor was about to shit da bed but yea u rock!!! :) she says thanx too!!!!!!

Don't you just love these videos that is concise and straight to the point in a nutshell. Keep up the good works and loved the Yodel at 1:16!

I have never commented on anyones video, this save me . I was so frustrated. Thanks a whole heap man.

My monitor had serious, constant flickering and black screening. This was solved by going into the monitor's menu and selecting reset. Changing some of the settings like Eco and HDR triggers the problem again and even causes a black screen which requires turning off and on the monitor, then pressing the menu to have the monitor display again. Resetting fixes this repeatedly. After fixing that, there is glitching as seen in the video. Confirmed my cable is 1.2 as I changed the refresh rate to 120Hz from 144Hz and the glitching stopped.

Upvoting because you fixed my issue - thank you.

I think you may have just saved my monitor fam. I am so happy. Thank you so much

I have windows but you saying that I was at a different refresh rate saved my wallet thank you

In my case, I managed to record when the game flickered, then in the recording the flickering is also appreciated, what could it be all about?

This was so helpful!!! I was about to throw my monitor out the window

Really helpful, thanks mate for making a video!

This is insance. I bought a new hdmi cable, force update the newest driver, and this simple switch, viola! Thank you comrade.

dude ur actually goated, with the new mac os update is changed my monitors refresh rate and i just had to change it back to what it was and now works perfectly

if it not working and the screen go off and on , try put the monitor cable into separate power outlet, and it will work just fine

Mine was due to using an obsolete HDMI 1.4b cable on a 4k display running 4k resolution. I upgraded to a HDMI 2.1 cable and fixed that issue. It also unlocked new color bit depth and refresh rates in windows.

What about when turning the MacBook and monitor ON, the monitor flickers a couple of times before it fully connects to MacBook…?

Hey man, thanks a lot! Even though I use a Windows PC, I still followed your steps and they worked for me.

My fairly new AMD RX 6400 was working fine for a while, but my 2010 Samsung TV (Second Monitor) may be getting a little sensitive at the HDMI PC input, and so the picture flickers or sometimes goes black for a second or two. If I remove the HDMI cable from the AMD RX 6400, and hook it up to the HDMI output of my backup computer, everything works fine, and thus the TV works perfectly. If I instead hook the AMD RX 6400 to my Primary Monitor a second time, by using an HDMI to VGA converter, here too, everything works fine. So begin with, I had one long cheap HDMI cable, which was then connected to another long but good wide band HDMI cable, which then was connected to the TV. So the best I could do for the moment, was I reversed it such that the wide band HDMI cable comes first, and thus it is now connected to the RX 6400 instead, and the cheap one comes second in line, and this reduced the occurrence of the flickering dramatically.

Thanx. Fixed my SOOOO ANNOYING flickering issue with my newly bought Samsung ultrawide 34" screen.

also try changing the monitors to the same refresh rate as the laptop or macbook, this solved my problem(especially if you have a gaming monitor)

I loooooooooooooooove you!!!!

I have the exact issue. But I have my built-in display exactly at 60Hz and True Tone and Auto-Brightness both OFF. Still has the same issue. But I am running Ventura now. Is your fix persistently working for you?

Is there a tutorial for windows

Are you meant to make your monitor or Mac them main display when doing this

it doesn't fix anything

I found this issue too, for what seems to be the same monitor. I found this fix too. However, it changes back to 59.9hz automatically and starts to flicker again. Any fix for that?

What about in sonoma? There is no such options like this

how can it be a good solution to relieve a 4 k monitor, which is overwhelmed by itself, with a lower resolution? Then you can directly buy a wqhd monitor.

Mine is flickering and I only have one monitor

Thank you

mines connected to my ps4 and it keeps on flashing on and off and making a weird beep noise please help me

Thanks Man!

I really don't know how to do it in windows can you explain me?

Volume on max can't hear shit. Also do it on PC.

By the God's kind, I recently bought an Xiaomi 34" Mi curved monitor for my MacBook Pro 13 2018. when I connect it by an hdmi cable with Apple usb-c to hdmi adaptor, my MacBook's screen starts blinking , and no signal masage is on the external display. Seems like my MacBook can't switch between screens. MacBook stops blinking as soon as I disconnect the hdmi cable. It's good to say I connect it to my 55" 4k and everything is fine. Guys, what should I do?

You are amazing, thanks so much!!

can you do it without a laptop

Thank you! 👏

thank you so mf much brother

Thank you so much!!!!!

im trying this out but it looks like mac got rid of that option, any thoughts?

THANK YOU DFSNFDG SO MUCH THIS HELPED ME ÚNFFGDMN

Try changing port on MacBook which is connected to HDMI. It worked for me
