Question I switched GPU from a GTX 1070 to an RTX 5070 Ti, now the monitor cable no longer works ?

[eMsit91]

Hi everyone,
I'm writing this post because I recently upgraded my PC, switching from a GTX 1070 to an RTX 5070 TI graphic card. The PC was connected to a Samsung S90C TV (which supports up to 4K 144Hz) using a 10-meter HDMI 2.0 cable.
Before upgrading the GPU, everything worked fine. I was able to set the resolution up to 4K with HDR10 (obviously not reaching 144 FPS, but around 30 FPS).

After upgrading to the RTX 5070 TI, I noticed that the cable no longer works — not even at 1080p 120Hz without HDR. When I plug it in, the signal becomes intermittent, the PC freezes, and eventually reboots.

I tried connecting it with a 1-meter HDMI 2.0 cable, and everything works fine, even up to 4K 144Hz with HDR10.

How is this possible? If the 10-meter HDMI 2.0 cable worked at up to 4K 30FPS + HDR before, why does it not work now, not even at lower resolutions, with a more powerful GPU?

If I were to buy a 2.1 cable, I’ve read that even at that length 4K 120Hz isn’t guaranteed — and such a cable costs 80 euros.

Could anyone explain this to me or give some advice?
Thanks a lot!

Giulio

If the GPU is the only thing you've changed, what is the make, model and age of your PSU? Did you run DDU to remove all GPU drivers(intel, AMD and Nvidia) in Safe Mode, to manually install the latest GPU driver sourced from Nvidia's support site?

include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Hi Lutfij, thanks for your reply.
The PC has been completely upgraded (GPU, MOBO, RAM, CPU, PSU), Windows 11 Pro has been reinstalled, and the NVIDIA drivers were installed in Safe Mode using DDU (after also cleaning all video and audio drivers with DDU).


My specs:
CPU: Ryzen 7 7700 (200MHz OC | -20 negative undervolt | PBO unlocked with MOBO's max power limits)
CPU cooler: Air - Thermalright HR02 Macho Rev B
Motherboard: ASUS B650M TUF Gaming Plus (BIOS version 3208 x64)
RAM: ORICO Raceline Champion DDR5 6000 CL30 (timings overclocked)
SSD/HDD: 1 Samsung SSD 850 EVO 250GB (for Windows)
1 Crucial SSD CT1000MX500SSD1 1TB (for games)
1 Western Digital Black HDD WD1003FZEX-00MK2A0 1TB (for storage)
GPU: Gigabyte 5070 TI Windforce OC SFF
PSU: NZXT C850 Gold ATX3.1 Modular with 12V-2x6 connector for the GPU
Chassis: Cooler Master Elite 430 Black
OS: Windows 11 Pro

Your specs check out, apart from that case being a potential heat trap.

Per your initial post, the length of the cable being the difference would mean that you're in need of a higher quality cable, per my understanding. You're also comparing the internal construct/quality of an 1 meter long cable to a 10 meter long cable, we don't know if they're from the same brand and if they incurred any bends throughout it's lifetime. Got links(or pics) to both cables?

As for the temperatures, they are within the normal range.
After the overclock (OC), I ran several stress tests, all of which completed successfully (using OCCT, Y-Cruncher, TestMem5, Cinebench R23).

In-game:

• CPU: 75°C (keep in mind PBO is unlocked)
• GPU: 65°C

Regarding the cables, they are about a year old and have always been stored carefully. Both are fully functional and both are from Amazon Basics.

The strange thing is that the 10-meter cable worked perfectly with the GTX 1070 (including 4K), but now with the RTX 5070TI the signal is intermittent and mostly absent, until the PC eventually freezes and reboots automatically.

How old is the cable?

How old is the cable?

The 1-meter one is 8 years old and works without any problems.
The 10-meter one is 1 year old and worked fine with the 1070, but causes problems with the 5070 Ti (or the new PC in general).

Does it still work with other devices now the connector and wires have been moved around a bit. It could be a lot of things but generally bargain bin cables can have issues device to device
