Nvidia GTX1050, everything is red

What can be the problem if an Nvidia GTX1050 card makes everything red-ish, also in de vt terminal which is almost unreadable in default colors.
Do these things ever go bad while they still keep working?
It runs X.org on the 470 driver. I used this computer with FreeBSD before but that was with 13.x releases.

Also, if you have another video source (other computer & other graphics card) and can connect that to your monitor with another cable, you can test that.

Exactly.
First test if it's the monitor.
By my experience it's more probable the monitor became defective. But since I never experienced such a defect with a graphics card doesn't mean it has to be that way.
But again: test the monitor first, then as LibreQuest said, the cable(s).
 
DVI/HDMI are digital signals put over LVDS, it might be possible for the driver (the electronics, not the software) to be busted on two of the three colors. But then you won't have any green or blue color, only the red color would be shown. "Red-ish" seems to indicate there is some green and blue color coming through, which might have been possible with an old school analog signal like VGA, not with a digital signal like DVI/HDMI. So if there's some blue and green, just not very bright, it's probably the monitor.
 
If the monitor only accepts analog VGA or DVI-A, the converter (assuming recent video cards only outputs in digital, i.e., my RTX A400 has 4 mini DP but no others) could be broken, regardless it's separate one or contained as parts of the cable.

Anothe possibility could be you've erroneously dropped Blue and Green (if the "reddish" means Magenta, Green alone) in your ~/.nvidia-settings-rc or something else.

There are some GTX 1050 models with DVI. I'm not sure if they are DVI-A , DVI-I or DVI-D. :D If you're converting from DVI to HDMI perhaps the DVI is sending an analog signal. There were a few oem versions with VGA out as well.

Edit: the Amazon reviews for the VGA models say they were a scam hahaha no doubt. Anyway, this whole comment is likely not helpful.

The output is HDMI converted to VGA. It has a HDMI to VGA converter on the monitor that I forgot existed. It's because I had no HDMI input port left on the monitor.
The converter cable has a wire breach.

The card also has DVI and Displayport . Unfortunately I had

This 1 has HDMI. DVI and Displayport. What I didn't notice was the DVI to VGA converter in the cable that I used because my monitor had no HDMI left. It has a wire breach, so the VGA lost most of green and blue. Now replaced with a passive DVI to VGA piece, problem solved.
Kind of stupid. I just didn't see it. Tried a Debian live USB stick to rule out a bad driver, same problem. The Display on-screen button menu showed all colors normally so that couldn't be it either. It had to be the display output wiring.

To the forum admins: can we please stop remembering canceled content? It's absolutely annoying. Cancel means a reaction is discarded permanently.

Is your display a CRT? If it's a CRT you may also need a converter box for the VGA output. CRT monitors have a very sensitive DPMS that can cause the display to turn off and on unless they have a powered converter box.

Ir's good now. Just changed the (apparent) active DVI-VGA converter cable to a passive connector that just connects the different wires.
I have bad eyesight. Just didn't see the black cable in-between the display output line. Nvidia doesn't even have VGA for a long time but I missed it anyway.
