How do I fix the graphics in tinycore?

[Cecil]

When Tinycore boots the color is off and the graphics look very pixelated and off in some spots. I tried to load puppy Linux too and where words should be there were just random symbols. I checked the monitor out on a different computer and it worked fine. Could there be a problem with the graphics card or maybe a driver issue? I could not figure out how to change color depth and resolution on tinycore to see if tweaking these settings could fix the issue. It is on an old outdated Dell computer that I am trying to restore for an old man. Any help would greatly be appreciated and I'll upload a picture of how my screen looks.

That looks like a hardware problem, sometimes as simple as a loose/dirty connection, sometimes a bad cable, sometimes worse.  But I don't think it's a Tinycore problem.

If it's happening in both Tiny Core and Puppy Linux then agree probably hardware related, as NewUser indicated. Physically disconnect then reconnect cables to get fresh connection. Also unseat and reseat your graphics card after unplugging system and grounding self. Reboot and test.

The "old Dell" would point to the usual Intel + bad Dell bios problem. If your system has an integrated Intel gpu, then you need to install Xorg and xf86-video-intel (in a text mode, inside X it can corrupt the session due to loading a different graphics driver at the same time).

..and it's also worth checking if there's a bios update on the dell site.
