Performance Drop When Using HDMI Output

[DerdoWaggy]

So I recently got a gaming laptop:

 

Gigabyte Aero 15 XC: 

- RTX 3070 Laptop

- 10th gen i7

- 32gb memory

- 1tb ssd

- 4k oled display

 

It runs games and various other programs beautifully, but when I hook it up to my tv with the hdmi port, the performance drops. Super easy games at low res stutter like crazy. 

 

I checked the tv port, and it's an hdmi 2.0. I used the same cord as my roommates PS5, so I know that both the cord and the port both support 4k at 60fps.

 

I tried turning down the resolution on the laptop, on the game, and on the tv. Nothing helped. I checked to see that the tv was set to display 60fps, and it did outside of games. I tried extending display, duplicating display, and using the tv as primary display. 

 

Is there something I'm missing here? I'd appreciate any help at all.

 

This is my first post. Hopefully I'm doing it right-ish.

 

Thanks!

Nope you basically did everything right. However one thing. Is your hdmi cable 2.0 compatible? I've seen this weird thing happen a couple times where a older hdmi cable does display simple images and such at the correct resolution and framerate but the moment more data is pushed through it starts to act up.

 

However this doesn't explain why it is also doing it at lower resolutions. So my other advice is to use DDU to uninstall your display drivers and install the latest from nvidia and intel.

 

You might also want to check if when you are gaming over hdmi it isn't using your intel gpu.

Its a long shot but does the HDMI port run off the I7s IGPU or the Nvidia card? Might be worth checking in the bios.

It should allow both. Most laptops use the intel gpu as the hdmi connection but allow the nvidia card to passthrough. Unless your laptop is one of the stupid ones that doesn't. Then it is displayport adapter time (probably over usbc with your laptop).

Thanks for the response! 

 

So I looked into DDU. Is doing the uninstall and re-install going to be dangerous? I am not as well versed in how drivers work as I should be and I'd hate to brick my machine.

 

Also, I considered the possibility of whether the hdmi is using the intel graphics, but was unsure of how to check it.

So I've also got a mini displayport on here (micro displayport?). If the computer were using the integrated graphics, would using this port with a converter to hdmi for the tv potentially help?

 

How do I know whether the hdmi port is hooked up to the integrated graphics?
