HDR-enabled screens can show millions more colours and several more shades of brightness between black and white than normal displays.
This lets them show more detail.
The announcements follow the creation of a new scheme that defines what HDR standards a 4K TV must meet to let it be sold with an "Ultra HD Premium" sticker.
Sony, Panasonic, HiSense, TCL and Sharp have also announced forthcoming TVs that will qualify for the badge.
'Never go back'
Over recent years, the TV industry has focused on marketing 4K as a reason to upgrade. This signifies that a television has four times as many pixels as a 1080p high definition set.
Samsung's high-end TVs, for instance, use LCDs (liquid crystal displays) with quantum dots to create a picture. These are tiny particles that emit a different colour of light according to their size.
By contrast, LG uses OLED (organic light-emitting diode) screens. These use a carbon-based film that allows the panel to emit its own light when an electrical current is passed through it, doing away with the need for a separate backlight.
The issue was that OLEDs start at nearly perfect black levels and then work their way up to offer a wider-than-normal dynamic range.
Quantum dot LCDs cannot go as dark, but make up for this by having a higher maximum brightness level from which their dynamic range can go down.
In the end, a group of major industry players called the UHD Alliance set two brightness ranges, and said as long as a TV complied with one of them it could qualify.
The industry wants to avoid a repeat of the situation in which many of the original televisions sold as being 4K-capable ended up being unable to decode transmissions in the format even though they had enough pixels.
"The key thing is that you have had the involvement of both the content players as well as the technology guys," said Mr Mercer.
Disney, Warner Bros, Universal Pictures, Twentieth Century Fox, Netflix, Sky TV and Amazon were all involved in creating the new standard.
HDR Blu-rays
Amazon already started streaming a limited amount of shows in HDR via its Instant Video service in 2015, and Netflix has signalled it will also do so later this year.
New 4K Blu-ray players unveiled at CES will also allow compatible discs to play back in HDR, meaning films will be able to show more detail at home than when they were screened in most cinemas.
