Being in the AV install sell/install biz for many years, we steer clear of brands that have the well-noted HDMI issues. Unfortunately today many HDMI products go through minimal HDMI/HDCP testing and thats why it is still a continuous problem today. Availability of diagnostic logging from Quantum Data.The format of this part is open for the individual manufacturers to define within the scheduled timeslot. Scheduled testing of products 1:1 with other manufacturers.Testing in a system made up of products from different manufacturers eg a TV, STB, DVD and Home Theatre amplifier, using predetermined Test Scenarios.Īvailability of diagnostic logging from Quantum Data. This includes associated items such as EDID. Testing will use the test equipment from Quantum Data and can cover: There are two different versions of HDCP: HDCP 2.3 and HDCP 2.2. When it comes to 4K projectors and TVs, HDCP 2.2 is usually always written on the HDMI connectors. Testing 1:1 with Test Equipment against the HDMI and HDCP specification HDCP 1.4 and HDCP 2.2, on the other hand, were released at around the same time as HDMI 1.3/1.4 and HDMI 2.0, respectively. The plugfest offers three types of testing: Here is an overview of how & what is tested a plug-fest. the plug-fests a brand could check an engineering sample with other brands, not perfect but a great inexpensive way to check for compatibility between HDMI products. Most displays produced over the past few years have at least HDMI 1.4 ports, so you can have 4K videos. Different versions of HDMI 2.0 support HDR and HLG HDR videos. The biggest challenge are the AVRs which have to take the incoming HDMI/HDCP encoded stream, extract it, decode it and the re-encode it then export out to the HD display in exactly the same timing as the input stream.ġ way a brand could check their product for HDMI/HDCP was to attend 1 of the HDMI plug-fests. HDMI 1.3 to 1.4b: from 1080p at 120Hz to 4K at 30Hz. Regardless of any display of higher version of HDMI you may have, the source will always limit the maximum bit-depth potential. With HDMI 2.1 TVs, new consoles and Ultra High Speed cables, it might be time to upgrade. The maximum output for this spec is 1080p at 60Hz with 8-bit color depth. Also the certification was less crucial for an HDMI source or HDMI sync product as many are simply a plug & play type as no HDMI repeater was required. Practical Issues and tips: Most CableTV set-top boxes use HDMI 1.0. The only way I get image was using 1920x1080 on 5" display, and it is an invalid resolution for it, so I see very poor quality image because it is downsampled.In the early days compatibility between HDMI components was/is a major issue.īasically because few brands would spend the significant $ expense and time allowance required for HDMI/HDCP certification. I’ve tried setenv tdxargs video=… / saveenv / boot solution, but I could not make it work. It seems to be the same problem posted here: link text It seems like there is a failure when device negotiates HDMI resolution/refresh rate in my displays. After I install an image (I’ve tried TorizonCore with evaluation containers v5.1.0 and QT for Device Creation Demo Image v5.15.1) there is no more video output.Īfter doing a lot of tests, I’ve connect to an older HDMI television (more than 10 years old), and it works correctly without any problem.They show correct video output when I run Toradex Easy Installer, booting on recovery mode.Computer Monitor 24" 1920x1080 LG Flatron M2380A ( link text).Standard HDMI 7" display 1024圆00 ( link text).Standard HDMI 5" display 800x480 ( link text) Youll need an 8K TV for 8K gameplay, too, but there arent really any 8K PS5 games in sight (at least not right now), so thats a problem for another day.I’m trying to get video output from DSI to HDMI adapter, but I’m not able to make it work.
