KitGuru tried the Philips BDM4350UC 43in 4k IPS Monitor
A quote from the article:
Size matters, and don't let anyone convince you otherwise. It's particularly important with 4K screens. Whilst the pixel count gives you bragging rights in itself, viewing 4K on anything smaller than a 27in screen beggars the point a little, as it will be hard to make out the detail compared to the next resolution down. In fact, the larger the better. So how about a 43in 4K screen instead? This is what Philips has on offer with the BDM4350UC.Philips BDM4350UC 43in 4k IPS Monitor Review @ KitGuru
