Select quad view on the SWIT FM-U245HDR and four mixed-format sources share the screen, each window with its own gamma, gamut and Payload ID setting. Camera A can stay in PQ next to a Rec.709 feed from camera B, useful on a two-unit car commercial or a stadium touchline where cinema bodies meet system cameras. Picture-by-picture and picture-in-picture pair any two inputs, with the inset in a corner or the centre.

Two details are worth knowing before you build a layout. If SDI 4 has no signal, HDMI takes the fourth window. In four-screen mode some menu functions grey out and the audio bar shows four channels only, so deep analysis is best done on a single input.

HLG1000, PQ1000, S-Log3 and 2.4 HDR sit beside SDR gamma 1.8, 2.2, 2.4, 2.6 and BT.1886, with Rec.709, DCI-P3 and Rec.2020 targets. With Payload ID switched on, the HDR monitor reads SMPTE 352 data in the signal and sets itself. White point options are D55, D65, D75, D93 and DCI, plus user values between 4000 K and 9800 K.

Log footage can look right from the first take. De-log tables convert S-Log2, S-Log3, Log-C, C-Log, V-Log, RedLogFilm and J-Log1 to Rec.709, with PQ and HLG conversions for ARRI, Canon, Panasonic, RED and Sony material. A DIT can also load up to 13 user 3D LUTs in .cube format (17 or 33 points) from a FAT32 USB stick. An active user LUT switches those built-in menus off.

Calibration happens on the monitor itself. Connect an X-Rite i1 Pro OEM or JETI specbos 1211 probe (sold separately) to the front USB port, and the 3D LUT auto-calibration routine runs without a PC and reports before and after results. A measure pass finishes within 30 seconds, so a fleet owner can check a unit between jobs and recalibrate only when the numbers call for it.

Scopes overlay the picture with adjustable position and blending: waveform in Y, Cb, Cr, R, G, B or RGB with HDR nit markers and single-line mode, vectorscope, histogram and CIE diagram with gamut warning. The eye pattern assesses SDI signal quality on site, which saves guesswork when a long 12G cable starts to misbehave.

Camera crews get focus assist, false colour, zebra, blue only, SDI time code and aspect markers from 4:3 to 2.39:1. Anamorphic de-squeeze runs in real time at 1.33x, 1.5x, 1.66x, 1.8x and 2x, with a mag crop mode. On the sound side, sixteen embedded channels show on VU or PPM meters, any two can feed the speaker or 3.5 mm headphone socket, and Lissajous and 5.1/7.1 surround displays help with phase checks.

A detachable rod under the case fits 28 mm junior and 16 mm baby stands. Two top cheese plates with 1/4" and 3/8" threads hold a wireless video receiver, so the link lands right at the monitor on a short cable. Power comes from a rear V-mount plate, a 4-pin XLR input at 12–17 V or mains at 100–240 V. Maximum draw is 120 W, so battery shifts call for high-capacity packs, which are not in the box. The operating range is 0 to +50 °C.

Live systems connect too. RS485 carries UMD labels in TSL 3.1 or 4.0 in both directions, the GPI port offers six assignable pins for tally and on-screen tools, and gigabit Ethernet opens a web control page. SWIT quotes about 0.01 frame of processing delay. Four user profiles, five function keys and a key lock hold settings in place when departments share a monitor.
