Monitor pink in right side, again! help

[seekndestroy0501]

S230HL acer monitor. using VGA (lcd with led technology or sumthin)

I bought it, i came home, plugged in power adapter, there was this pink hue and waves going down in the right side https://streamable.com/oh3u7 (its almost unnoticiable in white, very noticable in black and dark colors)

Few days later, i contacted seller, checked it very carefully. got it replaced ,changed its power adapter. 3 days it worked perfectly normal. but yesterday exactly same problem with pink hue came back randomly when i was watching a video. (i though i was having a bad dream about the old monitor with problems)

If i look closely the pixels seem to be displaying correct color but the pixels are surrounded by pink lines, and the affected area i can see waves going down.https://gyazo.com/de005239105d7e92034dd831bb93c61d

The rest of the screen got a bit blurry when something is moving on screen.

I've made a post like this before but this is the most detailed one, so i hope someone can give me an idea on what the problem could be caused by. I wanna try everything that could fix the issue

What i've tried:

Tried a different VGA cable

Unplugging VGA cable, then holding power button to reset monitor.

Applying some pressure

Connecting power thingy to the wall

Thinkering a lot with the video cable

So VGA can't be a problem because the problem is still there without connection, or is it possible for bad/old vga cable to permanantly cause monitor defect?

even though its not cable problem could getting DVI to VGA cable magically fix it?

im feel really anxious and hopeless over the last few days idk what to do exactly

would getting dvi magically fix my monitor?

Try the Monitor on a different System. If the problem stays, contact the seller. If the Problem is only on your system, then it most likely has something to do with your system.

i don't have different system, isn't disconnecting the VGA then turning on to "Cable not connected" message not enough to say system is not the problem? 

Does problems stay on monitor until another system without problems is connected?
