Hey guys

I have started to encounter some small green dots randomly flashing on and off on tv screen.

 

I have ruled out overheating gpu

 

changed hdmi cables

 

changed hdmi ports

 

changed drivers

 

reseated gpus and ram

 

ran furmark and no errors

 

any help is appreciated

 

cheers

Check your HDMI connection, it may have come loose. Try a different HDMI cable. Also check resolution, if set at one your screen is capable of.

just noticed my power cable to pc was not pushed in all the way

 

hoping that was the issue

 

gonna test and see

 

cheers

Ok. Symptoms you describe lead me to believe it is a incorrect resolution or incorrect connection.

[mikeymike 360]

I have no idea what going on

 

Green dots and a circle appear every 10 min or so for a couple of seconds

[mikeymike 360]

I ran fur mark and heaven for 30 min each no errors

 

And ran memtest no errors

 

Any ideas guys?

Cheers

what exactly are you doing when this happens? Are you running P3D?  Flying or just sitting there?

If when running P3d, try different flights, disable addons, etc and see if you can narrow it down. See if you can get a specific repeat rate.

Could be a power supply issue.

[mikeymike 360]

HI

Thanks for your replies

 

Happens during flight and also soon random stuff on pc.

 

I have a corsair 850hx , hope it's not the psu

 

I am waiting on nvidia to release a new driver see if that helps

 

Maybe my tv? It's a Philips 46 inch lcd it's 5 years old maybe it's on it's way out?

 

 

I dunno

Anyone? Please

I googled "green dots on tv" and got a bunch of hits - all seem to point to an issue with HDMI. Can you get a screenshot - or is it like the screenshots on google? Just as a WAG, look VERY closely at the HDMI contacts on buth the units and the cable. See if any are scratched, broken, dirty, etc.

 

Good luck,

I had the same issue. I plugged the monitor into my other computer to test and it was fine. I then plugged it back into the original computer and all good. Strange, I am thinking there was some dust in the connector or something.

Hi Vic

 

I swapped hdmi cables and still persists and at the same spot.

 

I don't think it's a hardware issue as I have numerous tests and no errors

 

And I would think if it was hardware I would get fps drop and stutters?? In p3d

 

It maybe my tv?

This is strange so I had 30htz enabled via ncp

 

And on tv screen display settings I set 30hz interlaced

 

So I set tv back to 60

 

And have it only set via ncp at 30

 

Been testing for 30min and no green dots artifacts.

 

Could this have been the issue?

 

Cheers

Yes, could be it. You could try setting the tv to 30 and don't set a limit in ncp. One thing can catch you out, default the ncp profile before trying different setups and especially after updating the drivers.
