RTX 4070 on the new Galaxy Book 4 Ultra

kriskent2023 — Tue, 09 Apr 2024 05:23:06 GMT

Is there any way I can make the RTX 4070 the default graphics card instead of the internal GPU similar to what one can do to a lenovo unit? I am new to the samsung ecosystem of laptops and would very much like to know if there's a way to do this.

Also, connecting this laptop to a Samsung Oled G8 that supports 175hz, I am only getting 120hz on the settings. How can I get max setting for this?

Thanks

I would assign the 4070 to specific apps so can have that control but also ensure you're not using it for something mundane like Spotify. To do this...

- On desktop right click (or go to settings)
- Click on "display settings"
- Scroll down and click on "graphics"
- Here you can assign which video card goes to what app and you can add apps to that list.

This may be totally irrelevant but...

AFAIK for older nVidia discrete GPU chips + on-CPU GPU co-op was called Optimus. You may find some insights for GeForce GT 630M here:

And I assume current tech, what/why/how is explained here:

There's no issue / concern on individual apps as indeed there is a way to assign RTX 4070 as GPU.

The thing I am concerned about is that when i connect this laptop to an LG C3 or Samsung OLED TV, the windows control panel says it's connnected to the TV via the internal arc graphics.

Can someone enlighten me why the HDMI port or Usb C directly connects and uses the internal arc graphics and not the RTX GPU?

Hello! Thank you for reaching out! You should be able to do that from the NVIDIA control panel by right-clicking the desktop > NVIDIA control panel > Manage 3d settings > Proffered Graphics Processor. Please let me know if this helps!

It is set for high performance Nvidia processor, but still when connected to the LG TV via HDMI the control panel says no display connected to this GPU

Anyone? Any idea when will I see that the LG TV 4K C3 connected to the RTX 4070 dGPU?

I reformated the entire computer, connected it to an HDMI 2.1 on a high end monitor and it still stubbornly connects to the integrated GPU and not to the RTX 4070!

I'm so frustrated on this laptop already, my son's lenovo legion 7i pro with RTX 4080 is not having any problems like this, that his ROG PG27 oled monitor connects directly to the dGPU. Why can't this samsung laptop do the same!

No it didn't . Whether it is on usb c or hdmi connection the LG Oled tv still connects to the internal arc graphics

After looking into this further from what I'm seeing is that while you may be using the integrated graphics, depending on your use case scenario windows will auto select the GPU to use. For example if you're playing a game it will use your main the RTX card.

If your laptop is not using your RTX card at all I would recommend to also try going to the NVIDIA control panel > Manage 3d settings > Program Settings > Open GL Rendering GPU you can select your RTX card and in the same menu you can go to CUDA GPU and select your RTX card and set these for the programs you want to use this on.

If this does not help then the last option would be service. Depending on your warranty you will have a few options.

- If your device was recently purchased, you can check with your retailer on their return/exchange processes.
- If you have an extended warranty you can reach out to them to have service processed.
- If you're within the one year warranty, you can Private message me or one of our moderators or you can call in directly at 1-800- 726-7864 with your full model and serial number to have service setup
- If you're OUT of warranty, for depot type products (Soundbars, Home Theater Systems, tablets, ect.) that require to be shipped we recommend you speak with our depot team for pricing and to have the service set up: 1-310-669-4334.
