SRX-T420 (SRXT420)Discontinued

Sony 21,000 lm Ultra High Resolution 4K Projector


As soon as the first SXRD 4K projectors were introduced in 2005, the ultra high resolution and picture quality quickly identified these projectors as having unrivalled advantage over existing projection systems, for many high-end visualisation and general projection applications.

The SRX-T420 combines 8.8 megapixel ultra high resolution with 21K lumen brightness to extend the well established SXRD 4K family of projectors into applications calling for higher brightness.

The SRX-T420 combines new features such as new chassis design, improved optical engine and single lamp operation while maintaining compatibility with the existing ranges of lenses and input cards and operational interface. Users can benefit from enhanced performance while retaining compatibility with existing systems.

The existing SRX-T110 and SRX-T105 together with their predecessors are recognised in the industry as two of the most advanced visualisation systems installed in recent years.
Ultra high resolution projection

Exceptionally high native resolution of 8.8 megapixels configured as 4096 (H) x 2160 (V) to clearly display the most detailed images without artefacts

Pixels from the SRX-T420 are approx. ¼ the size of pixels from an HD projector for a given screen. Images are free from any visible pixel structure even when viewed close to the screen

The ultra-high resolution of the SRX-T420 is more than FOUR times the resolution of an HD projector which can make system configuration simpler and more cost effective by removing the need for multiple projectors with edge blending

Lower resolution HD images benefit from being automatically up-converted to 4K equivalent images for display by the SXRD 4K panel
High brightness, high contrast projection

The SRX-T420 is the brightest 4K projector on the market to ensure high light levels on larger screens with exceptionally good contrast images

The high brightness capability enables the SRX-T420 to better substitute for multiple projectors with edge blending or to be able to provide good light levels on large screens for presenting to large audiences in an auditorium
Superb colour tonal reproduction

The SRX-T420 is design for the most critical picture applications. The xenon lamp used in the projector achieves a wide colour range, assuring a rich tone of colour reproduction

The projector also features a Colour Space Conversion (CSC) function and gamma curve selection to ensure that industry standard colour space and gray scale is achieved for critical applications
Flexible input configuration

The SRX-T420 has utilises Quad inputs to handle input signals up to 8.8Mega pixel resolution. The four input slots can be configured with DVI-D or HD-SDI input cards depending on the image source device

Alternatively input card slots can be configured with a combination of different input cards for maximum flexibility when handling HD signals

1 x DVI-D input is fitted as standard.


8.8 megapixel resolution at 4096(H) x 2160(V)

The 4096 x 2160 native resolution of the SXRD 4K panel represents over FOUR times the resolution of full HD (1920 x 1080 pixel) projectors

The panel can display a single ultra high resolution image up to 4096 x 2160 pixels or be switched to simultaneously display separate images in Quad HD or Dual HD configuration on-screen
Tiny pixel size and inter-pixel spacing

The on-screen pixels projected by the SRX-T420 projector are approximately ¼ of the size of pixels displayed by HD projectors, for any given screen size

Additionally the SXRD 4K display panel has tiny inter-pixel spacing to ensure that no pixel structure can be seen in the on-screen image when viewed at close quarters.
High brightness projection
The SRX-T420 delivers a maximum of 21K lumens brightness. The lamp power can be adjusted between 51% and 100% power to suit individual installations and bulb life.
High contrast ratio
High contrast ratio of typically 3000:1 to ensure realistic tonal detail.
Accurate colour reproduction
Xenon lamps in the projectors provide a wide colour space and colour tonal reproduction. The CSC function of the SRX-T110 ensures that the projector can be set to the desired colour space, such as the ITU-R BT.709-3 standard or DCDM (Digital Cinema Distribution Master) colour space
Wide Signal Compatibility

The SRX-T420 can be configured with up to four input cards handling either DVI-D signals or HD-SDI high definition video signals

A single LKRI-003 input card can accommodate dual-link HD-SDI (4:4:4) conforming to SMPTE 372M or HD-SDI (4:2:2) conforming to SMPTE 292M

A single LKRI-005 DVI-D input card with HDCP compatibility can accommodate a wide range of signals in Progressive format from WUXGA (1920 x 15000) down to XGA (1024 x 768)

Input cards in Quad configuration are used to input ultra high resolution images up to 4096 x 2160 pixels

The SRX-T420 is supplied with 1 x DVI-D input pre-installed
Variety of lens options

The LKRL-90, x0.9 fixed focal length lens for rear projection in visualisation applications

The LKRL-Z series of zoom lenses offers solutions for a range of installations requiring throw ratios from 1:1 to 7:1

Most lenses in the LKRL-Z series have a lens memory function enabling the zoom and focus settings for a number of image formats to be stored in the projector memory for quick reframing when switching between sources with different image formats
