As far as I know there are no such monitors available at this point that don't have drawbacks or issues.
Yes, this seems to be the case. They mostly seem to have a 'but' somewhere.
LG 43UD79-B 43inch UHD 4K IPS ~Colour accuracy/burn in issues but great value, 43 inch
BenQ PD3200U 32inch UHD 4K IPS ~Reliability/Flicker issues reported but again excellent value, excellent colour accuracy
Dell UP3216Q 32inch UltraSharp UHD 4K ~Some reports of various issues, pricier, excellent colour accuracy
Seems that for something with great accuracy, quality etc 32" looks like there better bet but 40"+ is much more practical?
Whatever company brings out a 40 inch 4k display that has RGB pixel layout, no burn in issues with display port will be selling them like hotcakes.
Agree.
