See What the Director Intended ™

The Radiance Pro™ series supports 4k60 inputs, and outputs, including HDCP 2.3, HDR10, and HLG, and is compatible with Dolby® LLDV™ sources. Winner of a Home Cinema Choice™ Best of 2021 award, and a Best Video Product award in Australia in 2021, the Radiance Pro is not standing still. Lumagen is adding to its 22-year legacy of video processor development by continuing to enhance features and algorithms, and adding a single-input, single-output model for those who would like to place the Radiance Pro after the AV switching.

The Radiance Pro series of video processors offers up to ten inputs, four outputs, and a multitude of video processing, setup, and calibration features. Much more than an HDMI switcher, the Radiance Pro has a host of features to improve the image on your screen. It is considered by many experts to be an essential part of any quality home cinema.

Optimizing HDR content has perhaps become the most important video processing feature. The Radiance Pro Dynamic Tone Mapping (DTM) analyzes multiple regions of every frame of content, detects scene changes, and optimizes the image for each frame of content. Jon Thompson, a movie producer who is responsible for post-production image quality at a major studio, recently evaluated the Radiance Pro DTM versus the other options. He said that “the other DTM options are not even in the same league as the Radiance Pro.”

Scaling quality again comes to the forefront with the 4k projectors and televisions. It should be intuitively obvious that home cinema scaling must be evaluated at viewing distance using actual moving image video content. The Tektronix PQA600C quantitative image analysis program is used by major studios and broadcast networks and includes 30 years of development by perception physicists. It includes viewing distance in its evaluation of scaling. The Radiance Pro has the industry’s best motion picture scaling and scores more than 20% higher than the competition using the Tektronix analysis software. Lumagen’s scaling provides the best quality scaling for 1080, 720, and SD, sources for 4k projectors and TVs. Scaling is also essential for aspect-ratio control, especially when using an anamorphic lens. In addition, the Radiance Pro has an edge-sharpening feature that helps restore detail lost during compression of the digital content.

Minimizing signal jitter is an extremely important criteria for HDMI. The Radiance Pro 5XXX series HDMI output clock jitter has been measured at about 10 pS. This is an ideal clock to send to the audio processor to minimize jitter at the DACs. Reduced jitter at the DAC reduces distortion. Lumagen has many reports of the 5XXX significantly improving audio due to this ultra-low jitter HDMI output.

Reference quality colorimetry is often overlooked as part of a high-end home theater. The Radiance Pro can provide automated video equalization, using third party calibration software, with more accuracy than calibration without a 3D LUT. Using the Radiance Pro’s DTM, and Color Management System, you can See what the director intended™.

Other features include image-based instant-auto-aspect detection and selection for HD, 3D, and 4k UHD and HDR sources. Anamorphic support with, or without, an anamorphic lens. Image based auto-aspect selection, plus precise geometry adjustments including size, and masking, are available. The Radiance Pro’s Non-Linear-Stretch (NLS) feature allows the user to stretch 16:9 content to fill an anamorphic screen using their preferred settings. For 16:9 screens and TVs, an anamorphic image can be placed anywhere in the active screen area, or with zoom, and/or cropping, can fill a larger portion of the screen. Multiple configuration memories allow for different independent configurations, such as day, night, sports, and black-and-white.

The adaptability of the Radiance Pro is second to none. Using Field Programmable Gate Array (FPGA) technology, the Radiance Pro can add hardware image processing and setup features long after installation. The Radiance Pro is adding new features over time. One example is HDR Dynamic Tone Mapping was added four years after product introduction and is available to all Radiance Pro owners by simply updating to the latest free release.

Awesome, portable room divider for larger rooms
Color: Black, Color: Black
I chose this room divider to use in my son's room that also serves as my home office! It is 72" x 72" in size, so it truly blocks out the other side of the room for optimal privacy. Once it's assembled, it's mildly sturdy - as long as you can bet both ends with the "feet" in line with the ground. I wish that the framework poles had more of an interlocking system so that the divider was easier to erect. I assembled this on carpet, so I had some issues getting the divider to stop moving. It takes a lot of work to set up, as it is massive, so definitely have someone help you. I would suggest adding weights of some sort to the feet of this divider to keep it from shifting. I ended up leaning mine against a bookcase shelf so it wouldn't lean. All and all, this is a great product if you are looking to make a room multipurpose.

As described
Color: Black
Light weight, easy to put together and you can disconnect the ends and just roll the whole thing nice and tight for quick out of the way storage. Pretty sturdy, doesn't fall over if you bump into it, you could use it outside but if there's a lot of light you can see through a tiny bit if you're really close but I only tested this indoors so not sure about patio types

Versatile Room Divider With Easy Assembly and Strong Coverage
Size: 3 Panel 12FT W
I picked up this Siebwin 3-panel folding room divider mainly for privacy and room separation, and overall it works very well. Assembly is very straightforward, and the divider can be set up, taken apart, and stored without much effort. The fabric quality feels good, and the frame construction is stronger and more stable than expected. The support tubes especially feel well built and help keep the divider standing securely. One feature I really liked is the flexibility of the design. The panels can be used together as a complete divider or separated depending on the setup and available space. That makes it much more versatile for different room layouts or temporary privacy needs. The coverage is also very good, and the size matches the manufacturer’s description accurately. The fabric blocks light and background visibility well enough to provide solid privacy without feeling overly heavy. The wider feet also help improve stability compared to thinner folding dividers. Another positive detail is that everything arrived complete with no missing parts or damaged pieces, which made assembly much easier and faster. Compared to cheaper privacy screens, this one feels more durable and easier to customize depending on the situation. In terms of value for the money, it feels like a very practical and worthwhile purchase considering the size, flexibility, and build quality. Overall, a versatile and well-built room divider with easy assembly, strong privacy coverage, stable construction, complete included parts, flexible panel configuration, and excellent everyday functionality.

Stable, flexible in deployment configuration, creates true privacy and looks great.
Size: 3 Panel 12FT W
This is the second room divider panel I have installed, and there are several features about this one that I like much better than my older one. The fact that there are no gaps and that the material is thicker means you get more privacy or more hiding power, if you wish. My older divider has vertical spaces between each of the panels and the panels are half as wide as the Siebwin panels, so there are many vertical spaces. The Siebwin divider really creates privacy. Another feature that I really appreciate is that the legs are wider and stand off from the floor. On my older one the legs are flat and they're rather awkward to adjust because they create more drag on the floor. The feet on the older one also loosen if you turn them counter clockwise, so adjustments of configuration that require the feet to be moved are more complex. The older divider also must be deployed in a zig-zag fashion because he feet are not as wide, but this new one can be deployed and stable in a straight, an "N" shape or an arc. They are both the same length, but because the older one must be use in a zig-zag deployment it doesn't reach to the length of the new one. The Siebwin divider definitely costs more at $103.48, but it sports several features and advantages over the other brand, so it does a better job and is worth the extra cost.
