I have this problem with my PC (Core i5 13600K Intel UHD Graphics 770) | Video Corruption - Freeze

[Galindo1327]

Hello.

Almost 2 months ago I built my PC with the following specs:

- Intel Core i5 13600K (UHD Graphics 770)
- 32 GB RAM DDR5 6400 Mt/s
- No graphic card
- MoBo Z790 UD AC
- 180Hz Monitor

From the first days of use everything seemed normal until what you see in the attached images and videos happened. Every time this happens I have to force restart my computer (5 times to date).
I have talked to people and they have told me that it is a problem with the integrated graphics.

What is the maximum refresh rate that the Intel UHD Graphics 770 allows? I want to clarify that I use it with the maximum frequency rate that my monitor allows (180Hz/FPS) could this be the problem?.

Could you tell me what's going on?

Thanks. 🙏

I attach the following images and files:

Motherboard Gigabyte Z790 UD AC	Monitor SANSUI 24" X5 Series
1 x DisplayPort 1.2 HBR2 (21.6 Gbps) 1 x HDMI 2.0 TMDS (18 Gbps)	2 x HDMI 1 x DisplayPort 1920 x 1080 @ 180 Hz (8 bpc) = 13.18 Gbps

There is no bandwidth issue here in my opinion. It looks more like the video transmission is being interrupted by an external source of interference. Is the cable currently running along a power strip with a smartphone charger or something similar?

The best thing you can do is connect with a high-quality DisplayPort cable, for example:

Club 3D VESA Certified DisplayPort cable

Ok, are you telling me that it could be a problem with my power strip and not with my integrated graph? I am using one, but in my case it is impossible to stop using it. Could you explain to me why it would be a problem with the power strip and not with the integrated graphics?

Thanks.

If everything works fine most of the time, I think it's unlikely that the graphics hardware is fundamentally defective.

I don't think the power strip itself is causing the problem. But perhaps the way the DisplayPort cable is routed plays a role. And also the cable itself. Please watch this video to get an idea of ​​the role that electromagnetic interference can play in transmitting high-density video signals: https://www.youtube.com/watch?v=aKV0FiuVJ0E&t=285s

The video is about DisplayPort 2.1 UHBR20, but the basic statements always apply. So cable optimization could help.

Ok, thank you very much for your contribution, I will try to buy a display port cable as you mentioned because at this moment I am using an HDMI.
At the moment I am using an HDMI that I had before buying the monitor, would you suggest I change it for a newer one until I buy a Display Port?

[MUC]

I would advise you to use a monitor with the DisplayPort protocol, as this offers the greatest compatibility at 180 Hz. With HDMI you may be limited to 120 Hz. There have been reports recently that the latest graphics drivers only support the resolutions defined in the Consumer Technology Association (CTA) catalog for HDMI. And the maximum there is 120 Hz for 1080p. In addition, with your device combination, the AdaptiveSync function (variable refresh rate) is only available via DisplayPort. Try to get a high-quality DisplayPort cable (possibly even with VESA certification).

When connecting with HDMI, you must ensure that the cable can handle the bandwidth. There are the following official cable designations:

"High Speed HDMI Cable"	This corresponds to HDMI 1.4 with 9 Gbps. This is not enough for 1080p @ 180 Hz.
"Premium High Speed HDMI Cable"	HDMI 2.0 with 18 Gbps
"Ultra High Speed HDMI Cable"	HDMI 2.1 with 48 Gbps

[Galindo1327]

Thank you very much, for the moment I will use a frequency rate of 120Hz or less until I buy what you recommend. If something happens I'll let you know.

Hello, today a few minutes ago it happened to me again, this time the PC turned off.
Although I highlight the fact that I connected another device to my power strip today, but it only lasted a few minutes connected...
Even so, I followed the instructions you gave me and they were within my reach.
Are you sure it's 100% for the reason you gave me? There can't be another reason?
I don't know what to do anymore and it makes me a little angry that this happens to me.

Hi Galindo1327,

Thank you for posting in the community, let me help you resolve this issue. I see that you already have some exchange with @MUC. To further dig down this can you answer the following question for me:

1. Can you share the exact model of your monitor? or it is the SANSUI 24" X5 Series?
2. What driver version you are currently using?
3. What is version of your HDMI cable?
4. Have you tried using a different monitor or TV for testing?
5. Does this only occur on when you change your refresh rate to 180Hz?

Best regards,

Hi Dhanniel, let me answer your questions:

1. To be exact, the model of the monitor is SANSUI ES-G24F4.
2. I have the 32.0.1016078 Driver Version (according to Intel Arc Control).
3. I have a HDMI 2.0 (according to the monitor description).
4. Nope, I don't have another monitor.
5. Nope, even I had 120hz when it happened.

I attach a video of what happened yesterday.

Thank You.

Hi Galindo1327,

I have some follow up questions here, please answer the following:

• Just to confirm here you are using the HDMI cable that come with your monitor?
• Have you try using a displayport cable for testing? or have you tried using a different HDMI cable?
• Does it also happen upon boot up? Can you go to the bios and see if the issue will persist?

Best regards,

Hi Dhaniel, yes sure.

1. I haven't been using it for a few days, like a week, even if I use another HDMI 2.0 cable the problem is still there.
2. Yes, in fact, as I mentioned in the previous answer, I am using another HDMI cable. I haven't tried a DP cable yet because I don't have availability for one at the moment.
3. It has never happened to me when starting the PC, nor has the BIOS indicated an error. It would also be very difficult to see if it occurs by looking at the BIOS, since the problem occurs spontaneously, that is, at any time. In fact, it hasn't happened to me since I responded to your message.
