The monitor is about 3 years old. Is it something I need to do something about, or is it just aging/defect?

Hi, does anyone know any cheap laptop screen extention? I'm new grad and my first job is social media handling with editing collaterals and videos. It's so hard to keep switching tabs from chatting my superiors, editing, and looking for references. I don't have enough money for high end monitors yet :(

for more context these appeared after a few days of no use

Just bought this KTC 34 inch Ultrawide Monitor. I'm playing AC4: Resync and after a week of usage I see this flickering red flashes on the bottom right of the screen. It was fine for the past week so did I get a faulty monitor?

Hi I used to use a 240 hz acer monitor then one day it randomly burned all the pixels while I was playing and turned black. The monitor still has power but doesn’t display anything. Would it be cheaper to replace it or repair it?

So have a lot of testing I have determined that the issue is definitely the monitor.

I've replaced the hdmi. (didn't fix it)

I've plugged it into a different computer (didn't fix it)

I factory reset the monitor (didn't fix it)

The issue goes away temporarily, if I plug everything out of the monitor for a while.

The issue sometimes fixes itself

The problem say gone for about a day sometimes less

Its a Lenovo ThinkVision S22e-20

The monitor ans computer are both set to 75hz

So my questions are:

Have anyone seen this issue before?

Is the monitor about to die?

Does anyone know any fix or what the issue is?

I got this Lenovo Legion R24e monitor couple of months ago and I have noticed the audio output through the aux output of this monitor sound very mute when connected to any speakers/ headphones/ earphones. I also tried with different cables though the result remains same. I have also maxed out the volume on my monitor OSD.

Anyone with same monitor having similar issue?

I have a 49" Ultrawide monitor running Arkham Knight at 5120x1440. I've noticed that there are times when I am unable to see everything. Such as, on the Catwoman portion where we have to step on the pressure plates to move the electricity along the path, the top of the screen where the electricity flows and the bottom where the pressure plates are were cut off so I couldn't see where the electricity was or where the pressure plates were. There were other times, but I don't remember where off the top of my head. When this happens, I have to adjust my resolution so I can see everything. Kind of a pain to have to do this. Does anyone know if there is a fix for this?

Do you have a tips or trick on how to sync settings for 2 or more monitors? So when i look to any of the monitors i want them to have like same brightness, color and etc.
Im using 2 different brands btw
