j s1503559540 Posted December 5, 2008 Posted December 5, 2008 (edited) If a claimed 1080p TV does not include 1080p as one of the options in its EDID details does this mean the 1080p claim is a fraud? Edited December 5, 2008 by j s

MLXXX Posted December 5, 2008 Posted December 5, 2008 (edited) If a claimed 1080p TV does not include 1080p as one of the options in its EDID details does this mean the 1080p claim is a fraud? No. (Is this the EDID info the TV supplies for the component connection? Some 1080p capable TVs will only accept 1080p through HDMI, and will have different EDID info for the component connection.) Bluray players in default mode will output 60i when playing a Bluray disc and a high definition TV set accepts the 60i and may display it with a little bit of judder, which can become noticeable during panning. Some late model TVs are able to convert 60i from a Bluray player back to 24p, and then display the 24p smoothly (using a screen refresh at a multiple of 24p). A 24fps capable TV can accept 24p from a Bluray player but the Bluray player has to have 24p capability and be operating in 24p mode. Edited December 5, 2008 by MLXXX
j s1503559540 Posted December 6, 2008 Author Posted December 6, 2008 It's the HDMI EDID from a Kogan 1080p-32 TV that doesn't list 1080p. 1080i is in the list. I didn't know component even had an EDID. I don't have a Bluray player (yet) but noticed from my DP-S1 PVR that the "EDID Detail" doesn't list a 1080p mode (neither 50Hz or 60Hz). Connecting the same PVR to another 1080p monitor (Benq E2400HD) does list both 1080p modes in its EDID.
MLXXX Posted December 7, 2008 Posted December 7, 2008 (edited) To test the Kogan 1080p-32 on 1080p60 and HDMI input, if you have a pc that can be set to a desktop of 1980x1080p60 then connect from its dvi output to the hdmi input of the Kogan. A DVI to HDMI adaptor may be required (e.g. about $15 from Jaycar, their catalogue number PA3642). The video card driver may have to be set to 'allow modes not exposed by the display', or equivalent wording. The EDID does not always list all modes a device can actually accept. I'd be a little surprised if the Kogan 1080p-32 cannot accept 1080p60 with HDMI input. TV manufacturers focus on standard use, which would be a Bluray player outputting 1080i60. Only a small number of tvs can accept a Bluray player outputting 1080p24. (The ability to accept 24p is a special feature normally mentioned when a 24p capable tv is advertised.)

My desktop can do that but it would not be easy to move either the PC or the TV to do the test. The video card came with an HDMI adapter and is driving the Benq at 1920x1080p60. For peace of mind I guess I'll have to. Or buy a Bluray player and try that.
