Then we get their secret decoder ring.Īs Chris pointed out, the "CVR" in the Dell Manual table possibly is a foreshortening of To answer your return-question, here's my unqualified guess: maybe the monitor is reporting "CVT-RB reduced blanking (preferred)" in the EDID descriptor for that one-and-only 2560x1440 entry. If "-R" follows, it means reduced timing.įor more info than these public VESA articles supply, we need to be $5000-per-annum card carrying VESA members. The "9" suffix is obtained from the last digit of the aspect ratio 16:9 That spec explains the naming convention of the resolution fomats. It does specifically identify the 2560x1440 format. VESA also published a separate spec in 2013 called Coordinated Video Timings (CVT) Standard. Nor was it to be found in the VESA Display Monitor Timings specs (DMT). There were no references to it in the EDID tables (none that I can find). Until around 2013, the 2560x1440 QHD resolution wasn't popular, or maybe even a recognized standard. I made some progress learning the difficulty with this 2560x1440 resolution, and the reference to CVR. The latter using a widely cited Windows Registry hack, manually editing DALNonStandardModesBCD1 That search turned up these instructions: Thanks for the tip about AMD gpu and "Use custom resolution". This is the native resolution for DCI-compliant 2K digital projectors and displays."ītw. "DCI 2K is a standardized format established by the Digital Cinema Initiatives consortium in 2005 for 2K video projection. It too has some video modes that are unusually denoted. That thread pertains to the U3219Q monitor. There is a separate inquiry in this forum right now about Apple Macs and that 2048x1080 default.
Not sure what is does or how it applies to the issue but.ĬVR = An abbreviation of CVT (Coordinated Video Timings) and the mode CVT-R. Maybe we can coax Dell-Chris to ask internal Dell contacts what that CVR means. Oddly, all named modes except the final one are marked VESA.īut that last 2560x1440 one is marked CVR instead. In the manual, the next-to-last VESA mode before 2560x1440 is that 2048x1080 you mention.
