The '''Sony PVM-14M2U''' is a 14-inch multi-standard professional video monitor from Sony's M-series, introduced in 1997.<ref name="crtdb">[https://crtdatabase.com/crts/sony/sony-pvm-14m2u Sony PVM-14M2U], CRT Database.</ref> It is the 600-line, P-22 phosphor member of a family documented in one service manual alongside the higher-grade PVM-14M4U (800 lines, SMPTE-C phosphor) and the 20-inch PVM-20M2U and PVM-20M4U, plus their 14M2E/14M4E European and 14M2A/14M4A export siblings.<ref name="sm">Sony PVM-14M2U/14M4U/14M2E/14M4E/14M2A/14M4A Service Manual, "Specifications", Sony Corporation. https://archive.org/details/sony-pvm-14m-2u-service-manual</ref>

The picture tube is a Trinitron (Sony part [[M34KBE11X]]) with a 0.25 mm aperture grille pitch and 90-degree deflection.<ref name="crtdb" /> Sony specifies convergence at 0.4 mm typical in the central area and 0.5 mm at the periphery, high-voltage regulation of 3.5 %, and raster size stability of 1.0 % horizontal and 1.5 % vertical.<ref name="sm" /> Video bandwidth is 10 MHz ±3 dB on both the luminance and RGB paths.<ref name="sm" /> Colour system selection covers NTSC, PAL, SECAM and NTSC 4.43.<ref name="sm" />

Colour temperature offers D65 and D93 presets plus a USER setting adjustable from 3200 K to 10000 K, factory set to D65.<ref name="sm" /> Normal scan overscans the effective screen area by 7 %, and underscan mode pulls back to 5 % underscan.<ref name="sm" />

== Features ==

Every video input is a loop-through pair with automatic 75-ohm termination — the termination releases itself as soon as a cable is plugged into the matching output, so no terminators or switches are involved.<ref name="sm" /> The RGB/COMPONENT BNC trio accepts analog RGB with sync on green at 0.3 Vp-p, or R-Y/Y/B-Y component, and a separate EXT SYNC BNC takes a 4 Vp-p composite sync reference.<ref name="sm" />

A 20-pin REMOTE connector carries tally and parallel remote control.<ref name="sm" /> An optional SDI board adds a serial digital input and raises consumption from 90 W to 99 W.<ref name="sm" /> Audio is a single 0.8 W mono speaker.<ref name="sm" />

The M-series is known for power-supply failures and deflection capacitor problems; several board revisions exist, with later units using improved parts.<ref name="crtdb" />
