Someone posted a pic of their kid looking at a 4k screen...

I can't find the thread and have been searching this subforum and others for 2 hours now.

The poster said something to the effect of they got tired of waiting for OLED (I think) and bought a 4k screen while they were waiting. They posted a picture of it, said it was a commercial model, mentioned that you could split the screen into a 4-up input, and wrote that the display was so good that their kid jumped when something on screen scared her. They had nothing but praise for the screen, now I'm in the market and I'm trying to find this post again so I can look the screen up!

Help a brother out

I wish I could help you pinoopin exactly what you are looking at but I have seen an LG monitor on Linus Tech Tips YouTube channel that can combine 4 1080p inputs onto one 4k display. I saw it most recently in this video. He might have mentioned the model, maybe give it a watch.
