hmscott, I've replaced 5.. ASUS G75V, brand new.. 3 different models.. two different stores.. same error as he describes.

2 years later, I buy a brand new ASUS G750JZ, same problem..

Now I will get a SECOND new ASUS G750JZ the next week.. so if the same problem is there, what do you say? It's all bad luck? O.O

I know you say RMA everything, but it's kinda bad if you order 7 new Mercedes Benz cars and have to ship them repair station before you spent 1 minute with them because of broken window.

Master Po, because most everything that is a problem can be fixed via RMA - and the rest solved via a working replacement.

Not all similar sounding symptoms are the same problem, or the same source cause. Arm chair trouble-shooting, and jumping to conclusions aren't going to verify that the problem can or cannot be solved, it is only going to contribute to blocking others from trying to get the problem fixed via RMA.

And, it sounds like you are RMA'ing your laptops, at some point you will get one that works to your satisfaction, or you will give up. You haven't given up yet, why suggest others should give up before they even try?

I don't say RMA everything, I say test things, and determine if it is software / hardware or user error / interpretation error, and if you rule out all the things you can change, and it isn't fixed, RMA it through Asus to get it fixed.

Having done electronic component level repair in my early career, and now doing systems debugging and tuning on a large scale, I see lots of logical errors inexperienced people make in trying to save themselves the trouble of actually fixing a problem. They give up quickly, and long before coming to a point where it makes sense to give up.

Often I will come in and fix the problem in short order, or determine it isn't fixable and replace it - after they have sat with the problem for weeks or months - and the reason "because someone told them something unrelated didn't work out" is one of the symptoms of their blocked state.

Naysayers are a dime a dozen, people that fix problems are rare. Become that rare person that works to fix a problem instead of coming up with unrelated reasons to give up before you start 🙂

Your "problem" may not be a problem, if you keep finding it in everything you look at, you - your perception might be the problem.

Perception and interpretation play a role in visual debugging. If you just don't like what you see when it is working properly, maybe you just don't like it?

There was a poll on here months ago that asked who was seeing the lines, vertical or horizontal, there were hardly any that saw it. It sucks if you see something that bothers you, but doesn't bother anyone else, but that doesn't make it a problem that needs fixing - it is just a product you aren't compatible with and don't like.

The wavvy moving lines, and interference lines showing up on an external display sound similar to what you are seeing, but not the same.

It sounds like hardware problems I have seen before that can be fixed. So shooing someone off saying Asus can't fix it, before giving it to Asus to try to fix it isn't helpful, and is keeping that person from getting a repaired laptop. You aren't helping them.

I have used 3 different models of the G750, owned them for months, and used them with 23", 27", and 50" displays, 1080p and 2k, and have not had any interference patterns or moving wavvy lines on the outputs. And both my Chi Mei screens and AUO screen also look great.

In contrast to what you are saying you see, are you saying because I have 3 G750's in a row that don't have the problem, that I should expect all G750's to work the same - or be able to be fixed so they work the same - yes I do.

That is why I recommend an RMA to Asus to give Asus a chance to fix the problem. The problem doesn't exist in my 3 G750's and it shouldn't exist in other G750's either.

Sorry. Felt frustrated because I'm happy with the product and to have one tiny but still important thing be wrong is upsetting as you need to send it away and be laptopless for unknown time.

Look away from the screen after watching this forum page or any page makes me see waves on the wall for some good minutes. Guess it burns in my eyes like any light if you watch it long.

Sounds hypnotizing 🙂

Another thought, when I have had video interference it can come from a bad ground causing rolling interference patterns - also RF interference can take on that rolling interference pattern.

Have you tried this on battery, with AC cheater plugs that break the ground pin to rule out stray voltage?

How about in another location? At friends place, or work / school?

Yes, it's the same without the power, just running on battery.
