Screens with 33-megapixel resolutions, projectors that blend their output to go as large as you want and screenless displays hint at the future of TV at CES.
New TV tech has always been at the heart of the Consumer Electronics Show.
The focus of last year's event was smart TV interfaces, but attention has swung back to the screens themselves this year with Sony and others declaring 4k's time has come. The term "4K" refers to the horizontal resolution of such screens as they are all about 4,000 pixels in width.
Also known as "ultra-high definition", the format offers four times the resolution of the current 1080p HD standard and is best appreciated up close, or further away from a mega-sized screen.
There is a deluge of 4k displays on the show floor - some adding OLED (organic light-emitting diode) tech to offer richer colours, others slimming the screen's bezel down until it is almost not there. Samsung and China's HiSense have also made a splash by exhibiting sets with gargantuan 110in (279cm) images.
But the truth none of the manufacturers likes to talk about is that the challenge involved in packing so many pixels into a small space means their prices are likely to stay too high for most for a while longer.
Beyond 4k
Sharp's prototype 8k screen was best appreciated close up
So let's switch focus and explore what the next next-generation displays might be.
The most obvious bet can be found at Sharp's stall, where an 8k screen is on show. The 85-incher (216cm) offers more detail than a 33-megapixel photo. By contrast 1080p offers about 2MP.
Sitting at the back of a room our eyes simply aren't sophisticated enough to spot the difference, but close up the effect is startling. There's a real sense of depth without needing other 3D tech.
But bearing in mind most of us don't watch TV with our face centimetres away from our flatscreen, why bother?
"If 4k is the next great thing, then you can divide your screen into four sections and run simultaneous football games in full resolution on your 8k television," Sharp spokesman Brad Lyons says. "That has applications in bars."
Surgeons, he adds, would benefit from using TV equipment that can show up minute details hidden by current tech.
See-through TV
Samsung and LG' stalls have another hint of what's to come - the world's first curved OLED screens.
Samsung's Transparent Showcase
They're not quite the bendy TVs some had predicted, but the firms say the innovation should improve viewing angles.
Perhaps more exciting is a product that has just made it to market. Samsung's 22in (56cm) Transparent Showcase is a glass box big enough to contain a product - shoes in this case - that lets retailers float video promotions over the front panel.
Then at the end of the day, when unplugged, the glass turns black.
It hints at a time when TVs might be used as augmented reality devices, providing information about objects placed behind them.
"All LCDs are transparent anyway - they're a piece of glass," explains Don Hickey, Samsung's solutions architect for large format displays.
"We've just moved the electronics to get them out of the way.
"Going forward [larger versions] could be used in schools as a show-and-tell type of device... and it could be used at trade shows."
In the meantime HiSense also has a transparent 3D TV on show which it says should go on sale later this year.
