Linear Line appearing on screen

[rexa21]

Hello!

 

I recently notice some problems with my display. As it happens, I see that linear white lines appear on my display occasionally. Sometimes it's in the bottom left, sometime it's near the top right corner, sometimes in the bottom right. I'm not understanding why this is happening. Only a little part of the screen shows this linear flickering although it's tolerable but I'm worried because I just built my PC 3 months ago. I thought it was my Monitor's issue. But I tried another source and the linear flickering was gone. When I changed my display source to PC, the line reappears. Anyone knows why this happens? I didn't notice this problem with my previous Sapphire R9 270 Dual-X card.

Thanks in advance!

 

My PC Specs are:

 

1. CPU: Intel Core i5 4690K (Stock speed)

2. Board: Gigabyte Z97X SOC-Force

3. RAM: G.Skill Trident-X 8GB (at stock 1333MHz)

4. GPU: Sapphire R9 290 4GB Tri-X OC UEFI (Stock) (Driver: AMD Catalyst Omega Driver 14.12)

5. Monitor: Asus VX229H (Currently connected via HDMI to the PC)

6. PSU: Corsair CX750

7. Drives: 2 SSD's in RAID 0 and another WD Black and WD Green and an Asus DVD-RW

I've got an LG 32" TV that I was using as a monitor, and I think I had something similar. Mine was so fast I really couldn't register it right as it happened. All I could tell was something horizontal was going on with the panel. Couldn't even tell if it was across the entire panel, or just a local area.

That TV is now hooked to the Blu-ray upstairs & I haven't seen those lines at all since. (But I admit I'm not spending anywhere near the same amount of time as my PC) Both my PC & the Blu-ray were over HDMI, using the same cable, and at 720p resolution. GPU was the AMD A10-6800K iGPU. (Maybe something AMD does with HDMI?)

 

Can you use DVI and see if it still happens?

Pixel striping is usually a cause of contact issue in the VRAM on the PCB.

 

The common method for dealing with this is 'reflowing', which implies removing the fan and heatsink from the card, then sticking the card in an oven at roughly 190*C / 370F for 8-12 minutes. (This is the melting point of common tin solder, so it may need more heat if something else is used, but this is unlikely)

 

If the card is still under RMA period or warranty, you should send it in rather than do it yourself.

Ah. Seems like we had the same issue. Well, my monitor is equipped with 2x HDMI and a VGA port. My GPU doesn't have VGA. I don't have any DVI to VGA converter either. The thing is, when I plug my monitor to an external TV card (via VGA), the flickering goes away. When I again change the source to PC, flickering comes back. But, this situation doesn't happen on a regular basis. I see them 2-4 times a month.

So I'm having this pixel stripping problem? (I searched the net and some people said that they were getting flickering and black screen because of AMD's ZeroCore). Anyway, yes. It's still under RMA. Before posting here, I took my card to retailer to deal with the issue but all they did was insert it into one of their testing platform and checked for the problem. But they didn't see any flickering (As I mentioned, it happens sometimes, not always). Although I said it happens sometimes, they said, it isn't any big problem and since I still have more than 1.5 years warranty left, they just asked me to use my card anyway and they'll look into it if any bigger problems happen.

 

What should I do now?

If the problem couldn't be reproduced on a test bench it could be software, motherboard, PCIe slot, monitor or cable issues.

 

But it could also be that the testing they did didn't fully utilize the VRAM, thus if 1 NAND unit has soldering issues, it could appear fine until data tried to pass to and from that chip.

 

Of course, if you're seeing this on the desktop when the PC is freshly booted, that isn't likely either.

 

Have you:

 

• Reseated the card in the PCIe slot/ cleared the PCIe slot of potential obstructions blowing air on it
• Tried another cable
• Tried another monitor
• Tried other drivers
• Tried the same drivers on a fresh installation of Windows

I reseated the card a few times. As of this writing, there's no flickering on my current PC setup. It appears sometime and then gradually fades away. Kinda odd. Tried another cable? Yes. I've tested with 2 HDMI cables and when the flickering occurs, it happens on both cables. Another monitor? No. Haven't tried that. Another driver? Should I revert back to any older driver and check for sometimes to see what happens? Reinstalled Windows 8 and upgraded to 8.1 3 days ago.

 

Will I face any bigger problem with my GPU in the long run?

Terve!
I had a similar problem with my 7970, but that was becaus my stupid mainboard was killing it, which I don't hope happens to you.

However, if you can, I suggest that you take your GPU to an other PC (make shure the driver is installed correctly on this one).

It can be the one from a friend or someone in you family. If it occours than as well, I do not think that it is about the card.

The best thing would be to switch two cards from two PCs, so you can still use it and the other person can make intensive testing. 

Also, I don't think that is due to zero core, since it disables unneeded cards in CFX.

For the part of "Will I face any bigger problem with my GPU in the long run?"

I can only say that you cannot know this.

I hope I could give you some more ideas.

Sayonara!

What I would do next is first try the previous graphics driver, then if that doesn't change it, try a DVI cable. Also, if you have a recent Intel CPU, disable the iGPU in the BIOS/ UEFI. Process of elimination. If those avenues aren't fruitful, and the place you bought it from won't RMA it, try the reflowing yourself. (It shouldn't leave any physical signs if you do it correctly, so your warranty would still be good)

So how would this apply to me using the iGPU on my APU?   I would think if there was an issue with my VRAM (system memory in this case) it would show up as well when doing memory intensive tasks...

Whatever was going on with my panel, I'd almost describe as an incredibly fast shot of static across some of the horizontal lines. It never had color, regardless of what was on screen. Like an old rabbit ears TV antenna, maybe.  Is this the same thing?

Quick question.  What line isn't linear?
