4K video projector

4K or UHD projectors have a resolution 4 times higher than those of the classic Full HD models. If this is indisputably the standard of the future for films, sport and video games, this standard is still at these beginnings and the majority of content (TV program, films, series, etc.) are still in HD. See the selection of Best 4K video projectors For 2023.

4K, Ultra HD and HD

There are several terms to designate the very high definition. We very often find the name 4K For consumer products such as televisions or video projectors, but these are often devices UHD, For Ultra high definition. Although very close, the resolutions of these two standards are different.

To be strictly speaking, 4K is more a format for cinema (filming and projection) but this term has returned to everyday language to designate the UHD.

The main resolutions

• SD (Standard Definition): 720 x 576 pixels
• HD (high definition): 1920 x 1080 pixels
• UHD (ultra high definition): 3840 x 2160 pixels
• 4K: 4096 × 2160 pixels

Quality difference between HD and UHD

Although there are 4x more pixels in the 4K/UHD image, the perceptible difference will be less than between SD and HD, especially for small and medium -sized sizes of image.

However, the larger the screen, the more the quality gain will be visible and it is more with a video projector than a television that you will perceive the difference between 4K and high definition.

4K technology

There are several types of UHD/4K video projectors. To summarize, we can distinguish three main categories:

• Native 4K video projector: the resolution of the projection matrix is ​​really UHD (or 4K). These are generally the most expensive models (and they are relatively rare).
• 4K video projector by Wobulation: UHD resolution is then obtained from Full HD matrices (1920 x 1080 px). The principle consists in quickly moving matrices to artificially increase the number of pixels (and thus create an image 3840 x 2160 px). The terminology used depends on manufacturers (e-shift, pixel shift, etc.)).
• Pro-UHD EPSON video projector: they project an image with a resolution halfway between HD and 4K. Epson uses the expression “4K improvement” and talks about 4K pro-UHD resolution. These “semi-UHD” projectors are compatible with a UHD signal but will only display half of the pixels (the double all the same of HD resolution).

For more information on the differences between these 2 “formats”, you can consult the following two articles:

• 4K Pro-UHD technology (on Epson.com): This page describes the principle of this technology.
• Pro-UHD vs UHD (on benq.com, in English): the pro-UHD seen by a competitor of Epson and his faults compared to the UHD.

In practice, Epson designs excellent 3LCD pro-UHD video projectors which do not have to be ashamed of UHD models. Resolution is not the only element that determines the quality of the image rendering.

The majority of UHD video projectors are to date 4K simulation models.

HDR (High Dynamic Range)

To summarize, an HDR compatible video projector will make it possible to project an image with more nuances of brightness, that is to say that you will better perceive the details both in light tones and in dark tones: The image will be more contrasted, more lively and more natural.

If HDR is not necessarily associated with ultra HD, most 4K projectors are compatible with this new standard, which is available in several forms. You will find the names HDR10 (the most widespread), HDR10+, Dolby Vision, etc.

Should we go to the UHD ?

When the emergence of a new standard, as is the case for the UHD, the question arises whether or not to choose compatible equipment, in this case a 4K video projector here.

HD or 4K ?

There are advantages and disadvantages to take the plunge now:

• Exceptional image quality: with a resolution 4 times higher than HD, the image will be particularly clear and it will be difficult to distinguish pixels, even for very large screens.
• “Future-Proof” projector, that is to say with a technology of the future (compatible with the next diffusion standards).
• More expensive: 4K technology is still relatively recent and choosing a UHD model generally requires a higher budget. At equal price, a Full HD projector will generally have a better rendering (contrast, color, etc.) that its 4K equivalent.

Keep in mind that resolution is not the only component as to image quality. The contrast and color rendering are in particular to be taken into account before choosing your video projector. In summary, it is better to have a good quality HD projector than a UHD projector with a poor image rendering.

4K and UHD content

To take advantage of the quality of a 4K video projector, you will need Ultra high definition movies and programs. This is no longer really a problem today because UHD content is now legion.

You can cite the mell Blu-ray Ultra HD (you need a special blu-ray player), the UHD programs On Netflix, Amazon Video Prime or YouTube, 4K games on PlayStation or Xbox or the 4K Internet box (with optical fiber). In addition, Apple TV, as is Google Chromecast are now available in 4K version.

Ultra HD 4K / 8K video projectors

Before exploring the specifics of 4K video projectors, let us remember that the term background projector is not appropriate to designate our subject. The retroprojector diffuses a fixed image, while the video projector projects videos. That’s said !

Identified as the most upscale models on the market, 4K UHD video projectors are able to display a definition of 3840 x 2160 pixels, and even 4096 x 2160 pixels for certain models. With this type of video projector, the most demanding moviegoers are able to take advantage of the latest generation content in optimal conditions. Whether it is to watch movies or to play video games, 4K projectors provide life -size experience worthy of dark rooms. We will distinguish video projectors 4K natives video projectors offering a 4K simulated. Rest assured, in both cases, the management of 4K content is total, in particular thanks to compatibility Hdr (HDR10+ and HLG) and an HDMI 2 connection.1 or 2.0. It should also be noted that a 4K HDR upscaling system is practically always available to enhance your Full HD 1080p content. In terms of sources, the 4K video projector has a fairly provided connectors to accommodate a 4K UHD Blu-ray player, a Mac/PC computer and a 4K game console. In addition, be aware that most of the state-of-the-art video projectors include an Android TV operating system (or other) and Wi-Fi connectivity to enjoy thousands of content online.

Several technologies can equip Ultra HD video projectors. Video projectors Dlp are the most affordable, but you can always opt for a matrix video projector LCD Or Lcos (SXRD, D-ILA, 3LCD). The light source can be generated by a classic lamp, or by a laser on certain high -end models. In terms of image quality, a 4K video projector allows you to display a giant image of up to 4 m without loss of legibility !

Why buy a 4K UHD video projector ?

There are many reasons to get a 4K video projector. The most obvious is obviously the wish to view 4K content in optimal conditions. If some Full HD video projectors have a upscaling function, nothing beats a device specially designed to decode the 2160P flows. However, it will be necessary to spend more to afford a native 4K UHD compatible projector. Some manufacturers have therefore given birth to more affordable models, capable of simulating an ultra HD definition thanks to intelligent algorithms. Be careful, we are talking about real 4K here ! And this is an excellent compromise between a high -end ultra HD video projector and a Full HD 1080p video projector. A 4K video projector also allows you to take advantage of the potential of dynamic beach images extended thanks to compatibility with the latest HDR standards and the integration of sockets HDMI 2.1. In addition, the 4K UHD 4K video projector is the one and only solution allowing you to display a very large image (up to 4 m) without quality of quality. The viewing position can also be as close as possible to the screen without distinguishing from unwanted pixels. Guaranteeing an exceptional home cinema experience, 4K video projectors stand out by an impressive resolution. We also note that some models can reach hallucinating contrast levels and brightness peaks at 5000 lumens. If such specificities ensure a detailed image in semi-buzzed rooms, use in complete darkness is always recommended to live an optimal experience.

What are the best 4K video projectors ?

First, the best 4K video projector available is the one whose resolution is native. This means that it can offer a raw 4K resolution, with maximum details and fluidity (up to 60 i/s with HDMI 2.0 or 2.1). The type of lamp is also a determining factor when choosing a video projector. More efficient than conventional lamps, Laser lamps can reach peaks of superior brightness of 5000 lumens. They also have a greater lifespan (up to 30,000 hours), and do not deteriorate. However, laser lamps cannot be replaced. On the matrices side, if the DLP and the LCD remain solutions of choice, the LCOS matrices found on high -end video projectors Sxrd And D-ILA provide a more precise image, with better contrast and even richer colors. Matrices 3LCD Also ensure a faithful restitution of the image, with very natural colors and a beautiful light uniformity. The best 4K UHD video projectors are also equipped with comfort functions such as Trapeze correction and the Lens Shift. The latter allows an optical offset of the lens of the video projector, so as to optimize the image vertically and horizontally without distorting it. An extremely practical function to adapt the video projector to the part of your choice. Finally, you will note that the ideal 4K UHD video projector depends on the size of your room. Picoprojectors, classic, long, short or ultra short focal.

What brand of Ultra HD 4K video projector to choose ?

If everyone has its own advantages, manufacturers obviously distinguish themselves in terms of use and technology cases. First of all, note that the video projectors’ brands are divided into two categories: manufacturers of consumer audiovisual products such as Samsung, LG, Sony, and those specialized in video projects like Benq, Optoma, Epson, etc. Each of them now offers native 4K video projectors. We will find the most affordable, often equipped with DLP matrices, at Benq, Optoma or LG. With their high -end video projectors, Samsung, Sony and JVC are more generally acclaimed by demanding moviegoers. This is obviously felt on the price, with the use of laser lamps, SXRD matrices, or 8K compatibility (JVC). At first glance, we imagine 4K UHD video projectors in wide angle formats that we must install with a minimum 2 m decline to benefit from a comfortable image size. If this is the case for the majority of them, LG, Samsung and Hisense offer ultra -short focal models. You can therefore install them less than 50 cm from the screen, and display a breathtaking 4K UHD image whose diagonal can reach 3 m. Finally, we will bear a mention to the more confidential brands such as Xgimi, which develop compact 4K models that can be moved in all the rooms of the house.
