Screen Artifacting?

[NoLoMo]

I don't have any photos on me right now, I will try to get those up as soon as possible. First I thought my HDMI cable was dying on me because my second monitor kept giving me bars on it. That's the first photo, it went away as soon I hovered my mouse over it and I moved a window on the screen. So I bought another HDMI cable and the problem went away for a bit but now instead of bars I just get black blotches.  The mouse I icon I can see over the black blotches, and same thing I just need to move something on the screen to get rid of it. Some thing I've noticed is that it doesn't matter which monitor it is. Whether it's my laptop monitor or my secondary monitor. It just happens on the monitor that is inactive at that moment. Lastly if it were to be the video card which I hope it's not, wouldn't my frames drop while I'm playing my games?

Screen artifacting is caused by overheating and/or malufancturing VRam, or sometimes just by the monitor (which in your case can be ruled out I would say).

FPS drops do not necessarely need to happen if the VRam is overheating btw.

 

From what I gatherd you are using a laptop - does it have a dedicated GPU installed and if so which one?

What are the GPU temps when said issue shows up?

Did artifacting ever occure when gaming or is it exclusively happening on your desktop?

I haven't been checking my temperatures as of late but the last time I've checked it was around 70 celsius? I'll run a game for a while and give you a more defined answer. As for my laptop specs its: Aspire V5-573PG with a i7-4500U, 8GB of DDR3 memory, 4GB of 750M NVIDIA GeForce. So it just happens on the monitor that least being used at the moment, or my primary monitor. So say I have set my LG monitor as my main display, when I minimized the game it see it on the LG monitor but not on my laptop monitor. Though I've seen it on my laptop monitor as well when I've set it as my primary monitor. I do not see it though when I am not tethered to the secondary monitor. It has never happened while I am gaming though. My laptop is on  a CMSTORM laptop cooler with the linus noctua fans.

Ok I've played a different game that's a bit more intensive than SMITE, the other game is Riders of Icarus. So I noticed it happens when ever I minimize the game, so is that software issue at that point? The reason I say this is because when I exited the game I didn't see it. Either who this is the peak of the load and then after in idle.

85°C is quite high for a GPU but It would be possible that real temp reads the iGPU and not the 750m, so I'd double check that. 

Personaly I would recommend either HWInfo or MSI afterburner to check temperatures. (in this case afterburner is probably better, since you could also use it to check for GPU trotteling, which would be a direct indicator of overheating)

 

Also as coincidence would have it I actually have a acer laptop very simular to yours, the V5-573G.

Which runs a 850M & I7 4510U but from the outside it looks exactly the same as yours, which means same cooling build in among other stuffs.

Even though the 750 & 850 do have different GPU architectures, I dont think the difference should be 15°C~  since the highest I've ever managed to push my GPU was 75° and thats with a +20/+200MHZ overclock on it while playing BF3. (w/o the OC its around 71/72°C max.)

 

Also to note, by default the displays are powered by the iGPU and not the nivida one on that laptop. So theoretically even if the Nvidia GPU would overheat, it should not affect the display output on the desktop...

 

 

Anyhow, there is quite a lot of possible causes here, especially because Acer is, at the best, a medicore manufacturer when it comes to quality.

I'd still check the temperatures with msi afterburner and if they are normal, just go and do a round of driver updates for your CPU & GPU.

Also check your intel settings for the displays - rightclick somewhere on the desktop, select "Graphicproperties" or something like that (had to translate it), its the first "intel icon" option that will show up and check if there are some settings that could cause said issue, for example powersaving ones.

Alright I took several photos, from desktop idle the temp went from about 45 to 60 idle on the lobby screen. During the match I saw it go up to 70 and stay between 69-70 for the entirety of the game.

So overheating can be ruled out.

 

While taking these pictures you did have an external monitor connected, correct?

Because if not, something is hogging your iGPU, hard.

 

 

In addition to the fixes I posted previously, you could also try if setting the nvidia card as the main GPU perhaps fixes the artifacting.

To do so just go to the nvidia control panel (rightclick on desktop and select it there) and then choose:

3D Settings > Manage 3D Settings

Global setttings

search for Preferred Graphics Processor

and choose "High performance NVIDIA processor", apply and reboot afterwards.

 

This will basically make the system use your Nvidia card wherever possible, the laptop aswell as the secondary screen will still run via the intel iGPU, but every programm will now use the Nvidia GPU, which you should not feel performance wise. (I have my laptop running that way aswell)

 

Another option that comes to mind is that the iGPU just de-clocks itself and hence causes artifacting, which is possibly caused by the poweroption setting for the iGPU "maximum battery life" or that you are running your notebook in powersaving mode in general.

Yes I game in my second monitor.

I do have it on high performance mode.
