So I recently bought a new monitor. I have to send my original back for repair due to delamination of the screen. Anyway, the new monitor I bought, an AOC AGON AG322QCX, looks like it has an interlaced display. Kinda like on old CD games of the 90s where the video "skips" every other line. I've never had a monitor that looks like this before. It's very faint, but it looks like every other horizontal line is just slightly darker (or that there's a gap between every line.) Dark, light, dark, light, etc... and it bothers me because I end up focusing on the lines instead of the overall screen. I sit roughly 36" from the display. So I guess my question is, has anyone experienced this before? Could this be something to do with being a curved screen? Or maybe because it's a VA panel? Or that it's a larger 32" display? I've only ever had TN and IPS panels before, and nothing larger than 27", but also I've never seen anything like this before. I don't think the monitor is defective... but those lines really drive me nuts. So far I've tried: changing DisplayPorts on the monitor and the GPU using an HDMI cable instead of DP cable Nothing made a change. Any ideas or am I crazy?

Since I got it last Feb it should be. I believe it's 36mo for the warranty. I'll get ahold of Asus then. Hope they won't need a receipt, that's long gone. Thanks for the response. I just wanted to make sure it wasn't something I could have taken care of myself.

I have an ASUS MG279 27" 2560x1140 144Hz monitor that I bought in Feb 2017. Graphics card is a 1080 ASUS Founders Ed. About two weeks ago I started getting an issue on the left side of the display. Best I can explain it is that it looks like water dried behind the screen, or like the torn page of an old book. Basically a wavy line that started at the bottom left of the screen and when first noticed just ran about 2" up. Line is roughly 1/4" thick, and the display area to the left of it has a slightly darkened color. At this point it has moved up to all but about 3" of the screen. It is not visible on all colors displayed by the screen. For instance, beiges and the default "Windows Blue" are especially bad and certain grays and gradients of white and black are fine. There's been no change in the way it's been used. One thing I will say is that I work from home, so when I'm on their VM I set the resolution to 1920x1080 at 60Hz so the VM will allow use of both my screens. (The other is a native 1080p display and it doesn't play nice unless they're both set to the same resolution.) But that shouldn't make a difference. Otherwise, when I'm not at work, it's set to it's native 2560x1440 144Hz. Have tried to move to a different displayport input, no change. Have tried resetting the monitor to default, no change. My other monitor (native 1080p) looks fine with no issues. So it seems to be isolated to this one. I'm hoping someone can help me, because I'm having trouble finding anything on a Google search since it's hard for me to describe the issue in terms of a search. Any questions that might help, feel free to ask. Thanks in advance! I've attached close-up pics but they might be hard to make out. I "drew" one so that it'll make more sense.

Ahhh... that makes a lt more sense! Thanks. Yeah, I'm probably going to think about getting a more expensive DAC. Thanks all

I appreciate the possible solution, but if the hiss originates from the speakers, then it can't be ambient noise. If you put you ear close to the speakers, the hiss is very pronounced. If I move away and sit at the desk normally, it's still there, just slightly lighter as I'm further away. Doesn't matter if it's noon or 2am. The other thing about that is that it didn't start to hiss until I uninstalled the Realtek drivers. Before that it was fine.

I tried that myself. Glad it worked for you. No dice for me.

Now that this thread has picked up again, I'll say that I was able to get my DPC latency under control about two weeks ago. (Don't ask me to remember all the things I did). The crackling still persisted even with the normal latency, though. So I got a DAC which led me to post another thread. So I made one step forward, two steps back. lol

The speakers are on an AC adapter. It's an Philips amBX system, so you need both a power and USB connection for them. So both the speakers and USB are on separate adapters. I've even moved the speakers to one power strip and the DAC to another. I have also tried both 3.5mm jacks on the board. Even with getting the latency under control, it still crackles via the 3.5mm jacks. That's the reason I finally bought the DAC. If I plugged my soundbar into the optical out, no problems. My speakers however, don't have an optical input. Yes. The post dwindled off, but here was my original issue: Anyway, like I said above, I got the latency under control where it would stop spiking in LatencyMon and stay where it should. It didn't fix the crackling though. Unless I was on another output: optical, etc.) The DAC did help and worked fine and gave perfect sound until I was stupid and uninstalled/reinstalled audio drivers. Now, the only problem with the DAC is that slight hiss.

Ok, so I tried the AC adapter from one of my Roku sticks. (It's the same as the included AC block from the DAC 5v 1A). Still has a hiss.

I'll see if I can find a 5v adapter. Yeah, the 3.5mm jack on the mobo was my original problem. The same problem with two of the same boards (didn't do it with another brand, but I no longer have that one.) The latency would shoot up causing cracks and pops. I finally got the latency under control, but the speakers would still do the same thing. Monitor speakers are fine, digital input soundbar fine, but whenever I plug any set of speakers into the 3.5mm and switch to that output (front or back ports) it would immediately start to crackle again. By the end, before I got the DAC, I found that if I unplugged and replugged the 3.5mm jack on the board, that it would quit crackling... until I put it to sleep or shut it down. So I have no idea on that one. I just got sick of messing with it. But I've got a few different USB AC adapter boxes: phone, roku stick and others. One of them is bound to be the right voltage. I'll try tomorrow or Saturday and see if that fixes it and post any results.

Specs: Windows 10 64 bit i7 7700k ASRock Fatal1ty Gaming-itx/ac Asus Strix 980ti 16GB Gskill Ripjaw V Ram Thermaltake Toughpower Grand 850w PSU H55 Corsair water cooler OS installed to SSD (I also have an NZXT Sentry 3 fan controller, two mores SSDs and an HDD in a hot swap bay, and peripherals (mouse/kb, printer, external DVD, etc) Here is a link to the DAC. It's just a cheaper one off Amazon. https://www.amazon.com/gp/product/B00NJCCAKY/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 It can be powered through AC or USB. I'm currently using USB into a port on the back of the mobo. This doesn't have any drivers I can find. I'm guessing that's because it's basically just a passthough circuit board that changes digital to analog to utilize different outputs, nothing fancy. I didn't want to spend a lot of money since two of these boards have had a crackling issue through 3.5mm jacks. I just want sound that works. And it's a Mini-Itx setup, so I don't have an available slot to stick a discrete internal soundcard in. I'll throw it in since toastfacegorilla mentioned something. This is also a very old house. The wiring in this particular room is only around eight years old, though. And like I said, what's throwing me is there was no hiss until I uninstalled the Realtek drivers. Even after reinstalling them it has continued. Some more things I've tried: Changed the USB port the DAC power is plugged into Changed the USB port my speakers are plugged into (I have an amBX system, so it powers via USB & AC, plus you need a 3.5mm jack for actual sound input/output) Physically relocated the DAC further from the case Disabled sound enhancements in the digital adapter sound properties Hope all that information helps.

Ok, so I'm back with another audio question. So I ended up getting a DAC to take care of my audio latency issue (even though I got the latency under control, the 3.5mm jack wasn't having any of it.) So now I'm using optical digital out>DAC>3.5mm speaker. I got the DAC hooked up and all was well. Was having an issue with occasional white noise so I unintstalled the realtek driver (later I figured out the issue was just that I needed to force 2-channel PCM sound, so that is kinda my fault). Now, ever since I uninstalled the driver, and I mean immediately after it uninstalled and the sound went out, I hear a soft hiss from the speakers. It's really faint, but enough to notice even with some ambient noise in the room. I'm wondering if anyone knows why that may be happening. Once the computer restarted, it loaded the default HD Audio drivers and it was still hissing. Reloaded Realtek and still hissing. Rolled back to before the uninstallation with System Restore, still hissing. Unplugged the DAC and all cables, then plugged everything back in, still hissing. Anyone have any idea how to stop it or what it could be? Thanks

Ok, so another update. As I said before, those two things didn't fix the issue. The computer now seems to have lag performing normal tasks though. Opening File Explorer, opening Google Chrome, navigating to websites, etc, which wasn't there prior. I'm getting tremendous CPU spikes for seemingly no reason. I don't have to be doing anything that would put it under load. I just open task manager to monitor, open or navigate through one of the aforementioned programs (and others. It doesn't seem to matter which) and it'll go from 3%-15% (which is usual) up to 80%-100% while just sitting there. I ran LatencyMon while I was asleep, and the results are below:

Sorry. Those things didn't work. I put the computer to sleep for a few hours. Shortly after I came back to it for some work, the audio issues started again. Any other ideas?

Ok, I updated the directX libraries and enabled hpet via cmd prompt (it was already enabled in bios). After I restarted, sound is good. Granted, it sometimes is anyway, so I'll post back in a day or so with an update as to whether or not it fixed it. Thanks for your help guys. By the way, I don't know if it matters, but I forgot to mention in my original post. As well as trying the digital out, which worked fine, my monitor has built in speakers, and I tested them (mini displayport) via the GPU, and that worked fine as well. So I really do believe it to be isolated to the line out. At any rate, thanks again and I'll update the results soon.
