How to show Photos from PC Laptop onto 4k TV

I want to show JPG photos from my HP PC laptop onto a 4K LG TV, and of course I want it to be shown at the 4k resolution. When I connected the HDMI cable from the laptop to the TV and used the photo slideshow that comes with the PC computer, I believe all
I was able to do was screen share and so because the PC laptop has a resolution of just 1366 by 733 or whatever, it was completely pixelated on the 4k TV.

It seems like I should be able to show photos on the TV at full resolution, just not sure how to do it.

Are the .jpegs in 4K?

Instead of sending your laptop's display to the TV, you have to cast the photos to your TV. There are many ways to do this. I use a Chromecast. The

third generation Chromecast can cast at 4K if the original content is 4K.

 

4k TVs?

Hi,

What are good 4k TVs, not only for watching video but also playing games? I have read reviews that the Samsung UN55JU6500 55-Inch 4K Ultra HD Smart LED TV (2015 Model)
is good -

Would love other suggestions in the same price range.

Thanks
