Hey guys I owned this big screen TV and it is 4k hd TV. The screen size is 123cm. The pixels per inch are also great but this is costly. Never mind if you get a best quality product then you can spend money on this. I recommended this for 4k gamers because this can be used in gaming PC also. You can connect your pc or ps4 with this 4k TV. I hope you understand about this and choose a right choice for a 4k tv. Thanks
