Hi all,

I have this monitor: 34" Odyssey OLED G85SB, 0.1ms, 175Hz Smart Gaming Monitor

Its native resolution is 3440x1440

I do not have a desktop computer, yet.

I have an XBox Series S and a laptop, the HP Envy 17

When I connect this monitor with my XBox Series S, using the HDMI cable that came with the Xbox, and play a game the monitors sets itself to its native resolution. If I will open Netflix or Amazon Prime Video, the monitor sets itself to 3840 x 2160.

When I connect the monitor with my laptop, the only way to get the native resolution (3440x1440) is if I set the monitor to Game Mode. As soon as I set the Game Mode to off, the monitor reverts back to 3840 x 2160, resulting in a stretched desktop.

Can anyone tell me why is this happening?

Can you, please, also tell me, what does it mean when I am watching at 3840 x 2160 on this screen? Does it mean distortion and stretching?

Thank you

No one replied, not sure why, my question could be answered by anyone with a 4K laptop and a similar monitor (3440 x 1440).

Anyways, I've contacted Samsung Support (UK).

My question:
Why can I not set the native resolution of this monitor when I connect it, via Display Port, with my laptop, and Game Mode is off? Why am I getting black bars (top-bottom) when I set the Recommended resolution (3440 x 1440) in Windows Display Settings and Game Mode is off?


Samsung answer:
Our Samsung monitor is a plug and play device, and only basing on the capability of the source that is connected to it. When your Samsung monitor is on Game Mode, it lowers the resolution of your source to 3440 x 1440 since this is the max resolution it can handle but when the Game Mode is turned off, it will return to the resolution your laptop can achieve, so 3840 x 2160. The image on the screen of your monitor will not be distorted as long as the refresh rate is set to low when the resolution is on its maximum. But the real display of 3840 x 2160 will not be displayed by our Samsung monitor since its maximum resolution is only 3440 x 1440.

Your Intel Iris XE graphics can run at a Maximum Resolution of 4096 x 2304 @60Hz. Just a reminder that it would be the best to lower the resolution if you would like to set the refresh rate to max and if you would like to set the resolution to max, you can lower the refresh rate to have a better and fantastic experience and to prevent distorted display.

They then asked me to do a full monitor reset, set the native resolution and restart both the laptop and the monitor. This did not fix the issue, I was/am still getting black bars (top-bottom) when Game Mode is off, at 3440 x 1440.


So, they said:

Thank you [for the reset], and as I've validated the issue of your monitor, it will be best to set the resolution of your laptop to 3840 x 2160 if this is the recommended resolution of your laptop since your monitor will adjust on its display. It's okay that your monitor will exceed its display since it will be based on the resolution of your laptop.

Based on our Senior Tech Specialist, no need to worry even if your monitor will exceed its resolution since it will be based on the best resolution of your laptop. The reason your monitor is displaying black bars (top-bottom) when it is set to 3440 x 1440 is that it's not the best and native resolution of your laptop. In this case we suggest you to set your laptop's resolution to 3840 x 2160 so that your monitor can display a full screen and better display.

What are you, guys, making from all of this? Does it make sense to you or is it BS?

Not sure if anyone is listening, hoping to get a response.

Thank you

Response times on specific topics not always quick here and this is very specific.

Let me ask you this: What is the active refresh rate when using your using HP Laptop in game mode (3440x1440p) and not in game mode (4k) and what colour depth are you using?

I ask because the Samsung Tech pointed out your Iris XE can run at a maximum of: 4096 x 2304 @60Hz which is somewhere around 18-24 gbps of bandwidth, depending on the colour depth per channel. What is odd to me is that your laptop has DP 1.4a, which is 32.4Gbps. So I'm not sure if they understood that you're running DP 1.4a.

If I go on the Intel website, it outlines the limitations over HDMI, DP, and your integrated laptop display.

Intel® Core™ i7-1260P Processor (18M Cache, up to 4.70 GHz) - Product Specifications | Intel

Intel® Core™ i7-1260P Processor (18M Cache, up to 4.70 GHz) quick reference with specifications, features, and technologies.
www.intel.ca www.intel.ca

If you wanted to run 3440 x 1440p @ 175hz at 12 bit (per pixel) you'll be at 36.41Gbps.

Conclusion: I think Game Mode lowers the colour depth to 8 bit. When you disable Game Mode, it's probably trying to do 12 bit over 3440 x1440p @ 175hz. Which is too much bandwidth on DP 1.4a, which results in automatic resolution change.

Try making a custom resolution on your laptop at 10bit or lower. You can use this tool to help with the maths. Bandwidth calculator - Kramer Electronics

BTW: I don't have this laptop or monitor. I'm just bothered by the response from Samsung.

Let me know if this helps or if I am off my rocker... :D

For more context, Xbox Series S GPU can do HDMI 2.1. Which is 48 Gbps if I recall correctly. That is why it works and thats how I based my assumption on what the issue is. If you wanted to test that theory, try the HDMI 2.1 cable from your Xbox on your laptop. Your laptop supports HDMI 2.1.

Hello, thank you very much for your reply, I'm starting work soon, no time at all now.

I have managed to resolve this issue when using DisplayPort but not when using HDMI.

Specifically, when connected with DisplayPort, I opened the Intel Graphics Manager on my laptop and set the Refresh Rate to 120p. This resolved the issue! So, now I am running the native resolution 3440 x 1440 @120p, independently from if Game Mode is ON or OFF, on the monitor.

I will have another look at the HDMI connection later, after work, today.

Thanks a lot! :)

No problem. You could probably get higher refresh rate with 12 bit but not sure if its worth it. Alternatively you could go to 175 Hz at 10bit. Play around with it but 120 hz at 12bit is great :)

Hello again, thank you for helping me! Unfortunately, I do not have time but on the weekend I will be free!

So far, this is what's happening:

- Everything works fine with the DisplayPort connection. The monitor works at 3440 x 1440, @120p, 8 bit depth color

- It does not work when I connect it with the HDMI cable, which I have from my XBOX. I cannot set the Native Resolution. Windows 11 Home recommend 1920 x 1080. Another one I can set is 2560x1440. Nothing else works. I don't know what I am doing wrong. I have rebooted the laptop and also shut it down completely, and the monitor, too. I am trying to set the resolution from Windows Display Settings and the Intel Graphics Command Center. It does not work.

For the HDMI connection, I am using this Micro HDMI to HDMI Adapter

Why is HDMI not working?

The monitor runs the latest firmware.
My laptop is fully updated, BIOS included.
I am running the latest Intel driver. Not the HP driver, the driver from Intel.

PS: I bought this monitor to use it with the desktop computer that I will purchase in a few months. I did not buy it to use it with my laptop or with the XBOX. However, I think that it should work, I mean I should be able to set its native resolution. This is why I am asking these questions here.

- Everything works fine with the DisplayPort connection. The monitor works at 3440 x 1440, @120p, 8 bit depth color - Increase the colour depth to 12 bit. You should have bandwidth to do so. You'll want higher colour depth for HDR content and overall better colour (less banding).

I am trying to set the resolution from Windows Display Settings and the Intel Graphics Command Center. It does not work. You many need to share a screenshot from the Intel graphics panel. I don't have a device with a Intel iGPU to simulate or test.

It usually comes down to bandwidth but according to "amazon reviews" that adapter should work. I've added some comments in RED above.

Here are 4 screenshots. Two are with DisplayPort and 2 with HDMI connection, the HDMI is when the Recommended is 2560 x 1440.

When I am connecting with DisplayPort, I do not have any option to set color depth.
When I am connecting with HDMI, I can set the color depth but I cannot even set the Native Resolution.

Can you please tell me what is going on and how can I set the screen to its Native Resolution when using HDMI?

I'll try not to waste your time but you simply may need to create a custom resolution. Which should be the little '+' icon next to resolution.

You are not wasting my time at all, I am grateful that you are replying to me!

I cannot set up a custom resolution. When I press the + button, a simple menu appears on the left side with Width and Height. I input 3440 x 1440 there, Apply, but it does not set it. It reverts back to 1920 x 1080. The weird thing is that if I go to Connected Displays / Information, I can see the native resolution of my screen. It says, 3440 x1440 (60p Hz) and (100p Hz).

Why does it not appear in Windows / Display Settings or even on the Intel Graphics Command Center?

HDMI , Game Mode: OFF

Can you also tell me, please, why I cannot change the Color Bit Depth when I am using DisplayPort?

Honestly, I am stumped. The last thing I would try is disabling "Extend" in Windows (Windows button + P), try "Second screen only." Maybe the iGPU can't push both screens at the same time.

If you don't want to wait for others, try following up in that chain with Samsung.

Describe briefly that your laptop / iGPU has DP 1.4a and HDMI 2.1 which provide 32Gbps and 48Gbps respectively. Your cables I assume are DP 1.4a and HDMI 2.1.

You should be able to push on DP 1.4a:

Thank you very much for your support, I really appreciate it! :)

I won't connect the HDMI again, it's good for my XBOX, for my laptop DisplayPort achieves 3440 x 1440 at 120Hz, which is excellent for watching movies, all I can really do with my laptop.

I'm not sure why HDMI does not work. A few other things I could/might try - just out of curiosity - are to clean install the HP GPU driver, or even clean install the latest Intel driver afterwards, and post a question on Intel Communities. I have read a couple of threads with the same issue as mine, people unable to set 3440 x 1440 on the Iris Xe.

I can only laugh at the Samsung customer service in the UK. When I've asked them my question, they said, no worries, leave it at pseudo-4K, no distortion, our monitors are plug-and-play. LOL! There's clear geometrical distortion when watching in different than native resolution, a circle becomes an oval. I've also asked them other questions, like how can I disable the remote of the monitor from controlling my XBOX. They said, it cannot happen. LOL! Of course it can happen, you just go to Connected Devices / Universal Remote, and you disable/enable it there. I hope Samsung US CS is better!

All the best, thank you!

To resolve this, you may need to check and adjust the display settings on your laptop, including the resolution settings, and make sure that it is set to output at the native resolution of the monitor (3440x1440) when not in Game Mode. You may also want to check the monitor's settings or contact the manufacturer for further assistance in resolving this issue.
When watching content at 3840x2160 on a monitor with a native resolution of 3440x1440, it may result in distortion and stretching of the image, as the content is being upscaled to a higher resolution than the monitor's native resolution. This can lead to a less sharp and less accurate image quality. Therefore, it's recommended to use the monitor at its native resolution for optimal image quality and performance.

All the best from remote codes portal.
