• Started Sinks or adapters using MCDP2900 DP to HDMI converter chip? 10 Aug 2023

  For testing, I'm looking for sinks and adapters using the MCDP2900 chip. I learned from this forum that CAC-2504 is one of them. Do you know others?

  1920x1080@165Hz is doable with HDMI2.0 to DP1.2 adapters, provided their firmware will let it through. Its only roughly 400(CVTrb)/525(CVT)Mpixel/sec rate.

  I have yet to be convinced that the SM9000 can do 4k120 4:4:4. We also know DP1.4 can't do it unless doing a small amount of compression. I'd like to see any p…

  @BricoDepot1987 First, I work in the business and want to follow the trends. I know a company called Lontium is working on a chip that can do this stuff, but c…

  @CLUBBIE Be aware, DP1.4 can only do 4k120 with DSC [compression]. If you want to be on top of it all, you need HDMI2.1 on both ends, at least until (if ever)…

  @BricoDepot1987 This thread is about HDMI2.1 to DP1.4. Since DP1.4 has a bit more bandwidth than HDMI2.0, and DP1.4 monitors have been existing for a while, th…

  That seems to do it in the wrong direction..

  @net200777 the TV hardware may very well support more than the computer thinks. The EDID data presented by the TV to the PC, contains a list of formats that th…

  Thanks.. This got me curious. According to my link above regarding HFR: LG OLED TV models in the W9, E9, C9 Series and LG NanoCell LED-LCD TVs in 9500 and 9000…

  Please tell how you know this for sure. PC's can easily do virtual 4k120Hz, but send something else over the cable. Also, please do the 4:4:4 chroma test. PS:I…

• Replied to HDMI 2.1 to DisplayPort 1.4 27 Apr 2020

  Hmm.. Then again.. They seem to use this manual for all types. Note that the list of resolutions say "(8k models only)" for the 4k120.. Apparently the 4k monit…

  ..I would also assume that the EDID of this TV publishes the latest modes. Maybe this test's graphics drivers could not interpret the latest video modes. It sh…

  Found some confirmation that the 75SM9000PLA TV will do 4k120 or 8k60, although it doesn't say color format. But obviously it supports HDMI2.1.

  Found this note: 4) Only applied to above SM90. Even that is weak specs. What ports? All? One? Some?

• Replied to HDMI 2.1 to DisplayPort 1.4 27 Apr 2020

  Looks clear at first sight. I wish it was more clear, like in a spec sheet explaining what ports could do what.

• Replied to HDMI 2.1 to DisplayPort 1.4 27 Apr 2020

  Please post an official spec link confirming the port capabilities of the monitors you look at.

• Replied to HDMI 2.1 to DisplayPort 1.4 26 Apr 2020

  I would not bet on that. That vid proves nothing.

• Replied to HDMI 2.1 to DisplayPort 1.4 10 Mar 2020

  You won't get 4:4:4 at that rate. DSC most likely wont be that effective, so you need to wait for Displayport2.x to go there. Im pretty sure you dont have a si…

  ..but it bothers me that they didn't power it from the DP end through a DP male cable tail on instead of that branching mess. A female DP plug can not utilize…
