Can the original xbox one still play on a 4k tv even though it can't play 4k games?

Yes but no but watch what your tv does.

Samsung on most models will upscale which doesn't always turn out good

Yes, the original Xbox One can still be used on a 4K TV even though it doesn't support 4K gaming. However, it will only output at a maximum resolution of 1080p. When you connect your Xbox One to a 4K TV, the TV will automatically upscale the image to fit the 4K resolution. This can result in a slightly blurry or stretched image, depending on the TV's upscaling capabilities.

That being said, using an Xbox One on a 4K TV in 1080p should not cause any major issues. The image may not look as sharp as it would on a 1080p TV, but it should still be perfectly playable. You may want to experiment with different settings on your TV to see if you can improve the image quality, such as adjusting the sharpness or turning on any image enhancement features that your TV may have.

The Xbox One can't play games at 4K, You need to have the Xbox One X and a 4K TV or a 4K Monitor to get to play games at 4K and games that show Xbox One X Enhanced on them.

I don't think so, Robin. I had an LG OLED 4K TV. And the Xbox One S was connected to to the LG TV and I used to play 4K games. Even if that's the case to play only 4K Blu Rays, it's still not supporting.

The Xbox One S plays games at 1080p but if played on a 4K screen, it upscales it to 4K,

The One X is needed for true native 4K,

I upgraded my Xbox One to the One S at launch to get full use out the 4K media content,

Then i upgraded my One S to the One X at launch to play games and media at true 4K,

seeing that you've already tried what i would have suggested, I'm not sure of what else you can try.
