Reviews of the Trinitron were universally positive, although they all mentioned its high cost. Sony won an [[Emmy Award]] for the Trinitron in 1973.<ref name=shist>{{cite web |title=Trinitron's High Quality Image Wins Computer Displays Applications |date=2009 |url=http://www.sony.net/Fun/SH/1-25/h1.html |website=Sony History |url-status=dead |archive-url=https://web.archive.org/web/20090329093450/http://www.sony.net/Fun/SH/1-25/h1.html |archive-date=2009-03-29}}</ref> On his 84th birthday in 1992, Ibuka claimed the Trinitron was his proudest product.

New models quickly followed. Larger sizes at 19" and then 27" were introduced, as well as smaller, including a 7" portable. In the mid-1980s, a new phosphor coating was introduced that was much darker than earlier sets, giving the screens a black color when turned off, as opposed to the earlier light grey. This improved the contrast range of the picture. Early models were generally packaged in silver cases, but with the introduction of the darker screens, Sony also introduced new cases with a dark charcoal color, following a similar change in color taking place in the hi-fi world. This line expanded with 32", 35" and finally 40" units in the 1990s. In 1990, Sony released the first HD Trinitron TV set, for use with the [[Multiple sub-Nyquist sampling encoding]] standard.<ref>{{Cite web|url=http://home.bt.com/tech-gadgets/television/retro-tech-the-crt-tv-11363858003032|title = Fibre Broadband, TV Packages, BT Sport & Mobile Deals &#124; BT}}</ref>

In 1980, Sony introduced the "ProFeel" line of prosumer [[component television]]s, consisting of a range of Trinitron monitors that could be connected to standardized tuners. The original lineup consisted of the KX-20xx1 20" and KX-27xx1 27" monitors (the "xx" is an identifier, PS for Europe, HF for Japan, etc.) the VTX-100ES tuner and TXT-100G TeleText decoder. They were often used with a set of SS-X1A stereo speakers, which matched the grey boxy styling of the suite.<ref name=profeel>[https://web.archive.org/web/20160304055110/http://www.thevintageknob.org/VIDEO/KX20PS1/KX20PS1.html "KX-20PS1"]. thevintageknob.org</ref> The concept was to build a market similar to contemporary stereo equipment, where components from different vendors could be mixed to produce a complete system. However, a lack of any major third party components, along with custom connectors between the tuner and monitors, meant that systems mixing fully compatible elements were never effectively realized. They were popular high-end units, however, and found a strong following in production companies where the excellent quality picture made them effective low-cost monitors. A second series of all-black units followed in 1986, the ProFeel Pro, sporting a space-frame around the back of the trapezoidal enclosure that doubled as a carrying handle and holder for the pop-out speakers. These units were paired with the VT-X5R tuner and optionally the APM-X5A speakers.<ref name=profeelpro>[https://web.archive.org/web/20160304115635/http://www.thevintageknob.org/VIDEO/PROFEEL/PROFEEL.html "Sony PROFEEL"]. thevintageknob.org</ref>

Sony also produced lines of Trinitron professional studio monitors, the PVM (Professional Video Monitor) and BVM (Broadcast Video Monitor) lines. These models were packaged in grey metal cubes with a variety of inputs that accepted practically any analog format. They originally used tubes similar to the ProFeel line, but over time, they gradually increased in resolution until the late 1990s when they offered over 900 lines. When these were cancelled as part of the wider Trinitron shutdown in 2007, professionals forced Sony to re-open two of the lines to produce the 20 and 14&nbsp;inch models.<ref name=profeel/>

Among similar products, Sony produced the KV-1311 monitor/TV combination. It accepted NTSC-compatible video from various devices as well as analog broadcast TV. Along with its other functions, it had video and audio inputs and outputs as well as a wideband sound-IF decoded output. Its exterior looks much like the monitor illustrated here, with added TV controls.

By this time, Sony was well established as a supplier of reliable equipment; it was preferable to have minimal field failures instead of supporting an extensive service network for the entire United States.

Sony started developing the Trinitron for [[computer monitor]] use in the late 1970s. Demand was high, so high that there were examples of third party companies removing Trinitron tubes from televisions to use as monitors. In response, Sony started development of the GDM (Graphic Display Monitor) in 1983, which offered high resolution and faster refresh rates. Sony aggressively promoted the GDM and it became a standard on high-end monitors by the late 1980s. Particularly common models include the [[Apple Inc.]] 13"  model that was originally sold with the [[Macintosh II]] starting in 1987. Well known users also included [[Digital Equipment Corporation]], [[IBM]], [[Silicon Graphics]], [[Sun Microsystems]] and others. Demand for a lower cost solution led to the CDP series.<ref name=shist/> In May 1988, the high-end 20&nbsp;inch DDM model (Data Display Monitor) was introduced with a maximum resolution of 2,048 by 2,048, which went on to be used in the [[FAA]]'s Advanced Automation System [[air traffic control]] system.

These developments meant that Sony was well placed to introduce high-definition televisions (HDTV). In April 1981, they announced the [[Sony HDVS|High Definition Video System]] (HDVS), a suite of [[Multiple sub-nyquist sampling Encoding system|MUSE]] equipment including cameras, recorders, Trinitron monitors and projection TVs.

Sony shipped its 100 millionth Trinitron screen in July 1994, 25 years after it had been introduced. New uses in the computer field and the demand for higher resolution televisions to match the quality of [[DVD]] when it was introduced in 1996 led to increased sales, with another 180 million units delivered in the next decade.<ref>[http://blogs.spectrum.ieee.org/tech_talk/2008/03/sony_pulls_plug_on_historic_tr.html "Sony Pulls Plug on Historic Trinitron TV"] {{Webarchive|url=https://web.archive.org/web/20080821131827/http://blogs.spectrum.ieee.org/tech_talk/2008/03/sony_pulls_plug_on_historic_tr.html |date=2008-08-21 }}, ''IEEE Spectrum Online''</ref><ref name=wallst>[http://www.marketwatch.com/news/story/sony-stop-making-old-style-cathode/story.aspx?guid=%7B097C2A31-1395-41BC-A8B7-6A3A65B27F97%7D "Sony to stop making old-style cathode ray tube TVs"], ''Wall Street Journal MarketWatch', 3 March 2008</ref>
