===CBS HD===
CBS' master feed is transmitted in [[1080i]] [[high-definition television|high definition]], the native resolution format for CBS Corporation's television properties. However, seven of its affiliates transmit the network's programming in [[720p]] HD, while seven others carry the network feed in [[480i]] [[standard definition]]<ref name=re/> either due to technical considerations for affiliates of other major networks that carry CBS programming on a digital subchannel or because a primary feed CBS affiliate has not yet upgraded their transmission equipment to allow content to be presented in HD. A small number of CBS stations and affiliates are also currently broadcasting at [[1080p]] via an [[ATSC 3.0]] multiplex station to simulcast a station's programming such as [[WNCN]] through [[WRDC]] in [[Durham, North Carolina]], [[WTVF]] through [[WUXP-TV]] in [[Nashville, Tennessee|Nashville]], and [[KLAS-TV]] through [[KVCW]] in [[Las Vegas]], [[Nevada]].

CBS began its conversion to high definition with the launch of its simulcast feed CBS HD in September 1998, at the start of the [[1998–99 United States network television schedule|1998–99 season]]. That year, CBS aired the first NFL game broadcast in high-definition, with the telecast of the [[1998 New York Jets season|New York Jets]]–[[1998 Buffalo Bills season|Buffalo Bills]] game on November 8. CBS gradually converted much of its existing programming from standard definition to high definition beginning with the [[2000–01 United States network television schedule|2000–01 season]], with select shows among that season's slate of freshmen scripted series being broadcast in HD starting with their debuts. ''The Young and the Restless'' became the first daytime soap opera to broadcast in HD on June 27, 2001.<ref name="HDTV">{{cite news|title=Finding the art in HDTV|url=https://www.broadcastingcable.com/news/news-articles/finding-art-hdtv/97190|author=Karen Anderson Prikios|periodical=Broadcasting & Cable|publisher=[[Reed Business Information]]|date=June 25, 2001|access-date=July 17, 2015|archive-url=https://web.archive.org/web/20150722012918/https://www.broadcastingcable.com/news/news-articles/finding-art-hdtv/97190|archive-date=July 22, 2015|url-status=live}}</ref>

CBS' 14-year conversion to an entirely high-definition schedule ended in 2014, with ''[[Big Brother (American TV series)|Big Brother]]'' and ''[[Let's Make a Deal]]'' becoming the final two series to convert from [[4:3]] standard definition to HD (in contrast, NBC, Fox, and The CW were already airing their entire programming schedules – outside of Saturday mornings – in high definition by the 2010–11 season, while ABC was broadcasting its entire schedule in HD by the 2011–12 midseason). All of the network's programming has been presented in full HD since then (except for certain [[Christmas holiday season|holiday]] specials produced before 2005 – such as the Rankin-Bass specials – which continue to be presented in 4:3 SD, although some have been remastered for HD broadcast).

On September 1, 2016, when ABC converted to a [[16:9]] widescreen presentation, CBS and The CW were the only remaining networks that framed their promotions and on-screen graphical elements for a [[4:3]] presentation, though with CBS Sports' ''de facto'' 16:9 conversion with [[Super Bowl 50]] and their new graphical presentation designed for 16:9 framing, in practice, most CBS affiliates ask pay-TV providers to pass down a 16:9 widescreen presentation by default over their standard definition channels. This continued for CBS until September 24, 2018, when the network converted its on-screen graphical elements to a 16:9 widescreen presentation for all non-news and sports programs. Litton Entertainment continues to frame the graphical elements in their programs for ''Dream Team'' within a 4:3 frame due to them being positioned for future syndicated sales, though all of its programming has been in high definition.
