V-Sync causing significant issues on TV

[ninjonxb2]

I am currently trying to get Dolphin to work on my TV but I am running into issues when I enable v-sync. I drop down to about 30 fps (50%) which causes the audio to have serious issues also.

If I try to run Dolphin on my primary monitor (2k monitor) I am able to have VSync enabled, internal resolution to 6x, anti aliasing 8x, anisotropic to 8x with just the occasional drop.

I did test on the tv by setting all enhancements back to their default and the only thing that made any difference for performance was disabling V-sync.

However with it disabled I am getting really bad screen tearing. The tv is a 4k tv and windows sets it scale to 300%.

For sanity sake I checked my ps2 emulator and I am having no issues there, or any other game when I play it on my tv.

When I am running on the TV I disable my other monitor

I am not sure what I can try to fix this.

I am currently testing this with Star Fox Adventures.

Is this happening with Dolphin 5.0 stable, or the latest 5.0 dev build?

Make sure you have a HMDI 2.0 (or higher) cable and you're using a HDMI 2.0 (or higher) port on your TV. Then in Windows Settings > System > Display, make sure you have the resolution set to (3840 x 2160) 4K and not (4096 x 2160) DCI 4K. Then scroll down and go into "Advanced display settings" for the 4K TV and check that the refresh Rate is set to 60Hz (or higher). You may need to enable a "Game Mode" setting on your TV, depending on the model.

Go into the Nvidia Control Panel > 3D Settings > Manage 3D Settings > Program Settings tab > make a profile for Dolphin and set the "Power management mode" to "Prefer maximum performance"

Thank you for the reply

I don't think the cable I currently have is HDMI 2.0 but I am not entirely sure, it is 30 feet which I know is more than the recommendation. However I am moving soon and my computer will be closer to my TV so I will get a new cable then if nothing else works.

As far as the ports, that part I know is right. All of my stuff goes through my receiver (all of the ports on the receiver are the same) and when I test the connection with my xbox it reports the only thing I can't do is 120hz thanks to my receiver.

For the resolution, I don't have different options for 3840x2160. I just have the one that was recommended. No DCI or anything.

When I tried going to advanced settings and setting the refresh too 60, the screen went black until it reset back to 30 so I am guessing the issue is the cable. Had this cable for about a year and surprised I am just now finding out about this setting.

But thank you very much, at least that explains what is happening here.

What you might need is an Active HMDI cable to prevent signal loss. They're good for going longer than like 15-20 ft and wanting the full 4k60 signal. They're a little more expensive though

Edit: Or drop down to 1440p at 60Hz? For Dolphin at least it will be hard to tell the difference.
