Hi All, After fiddling with this issue on and off for the last few weeks. Finally able to resolve it. (for the most part). The resolution on my 4k monitor (Acer ET322QK) is OK, but not perfect. It turns out that MacOS Catalina sends YPbPr signal to my monitor and it makes the 4k screen looks blurry and with limited resolution support via HDMI cable. With DP connector, my monitor does not even detect the signal. I stumble upon the following article and was able to get MacOS to output RGB signal to my monitor. I was able to get 1920x1080 with HiDPi support via the HDMI and DP output. Anything higher than 1920x1080, the fonts becomes blurry again. ( I can go all the way up to 3840x2160, but it's just not worth it) https://forums.macrumors.com/threads/guide-fixing-external-monitor-scaling-and-fuzziness-issues-with-mbp-and-osx.2179968/ Hope this helps someone who have the same issues as I have.

Hi Herve, Thank you for the pointer. I was able to increase the vRam to 2048 after uncommenting the line. Base on the config.plist file, port@2 already set for DP and I should get output. Unfortunately, macos detect everything but its not sending any signal to the monitor. See the screenshot below. If I use a DP->HDMI adapter on port@2 (port replicator DP port), I do get picture on the monitor. Is there some option I need to tweak to make DP work ? Also, the monitor is a 4k monitor. Is there option to make macos support the 4k resolution ? Right now the HDMI resolutions are limited to 2560 x1600. Thank you

Hi Herve, Thank you for the pointer. I've read through your forum thread and here is my understanding. Please let me know if I am not correct. From the original "AppleIntelFramebufferAzul", This the hex output that I got 0600260A 01030303 00000002 00003001 00006000 00000060 D90A0000 D90A0000 00000000 00000000 00000800 02000000 30000000 01050900 00040000 87000000 02040900 00040000 87000000 FF000000 01000000 40000000 0F000000 01010000 04000000 00000000 0E000000 00000000 Which tell me that port5 should be DP and port6 should be DP. But base on my "ioreg -l" output I got the following. AppleIntelFramebuffer@0 "connector-type" = <02000000> "port-number" = 0 AppleIntelFramebuffer@1 "connector-type" = <00080000> "port-number" = 5 AppleIntelFramebuffer@2 "connector-type" = <00040000> "port-number" = 6 So it looks like it's been inject by Clover ? I can use the hdmi port from the laptop without issue. If using Clover, how can I change port5 to use DP instead of hdmi ? Can I increase the graphics card RAM from 1536 to 2048 via Clover ? Thank you.

Hi, I am trying to get display working through the docking replicator (DisplayPort). The OS recognize the external monitor and can identify the monitor model. But the monitor is not receiving signal and after a few seconds, it goes into power safe mode. Attached is the debug file. Hope some one can provide pointer or assistance. Thank you. debug_14677.zip

Jake/Herve, Thank you for the explanation !!

Hi Jake, Thank you for all the help. Sound is working now. (speaker/headphones). What is causing the issue ? Trying to learn here. I've attached another debug file here which sound is working. debug_10012.zip

Hi Jake, I've tried to repair permission a few times already. sudo spctl --master-disable sudo mount -uw / sudo killall Finder sudo chown -v -R root:wheel /System/Library/Extensions sudo touch /System/Library/Extensions sudo chmod -v -R 755 /Library/Extensions sudo chown -v -R root:wheel /Library/Extensions sudo touch /Library/Extensions sudo kextcache -i / debug file attached. debug_22705.zip

I updated my laptop from 10.15.3 to 10.15.4 last night. - Upgraded Clover to r5107 - Upgraded Lilu, weg and AppleALC to the latest. All hardware seems to be working fine except audio. "System Information"->"Audio" is blank. Any help is much apreciated.

Hi Herve, With my current setup 10.5.3 from the guide here, how can I safely update to 10.5.4 without messing my install ? Is there any steps that I can follow. Thank you

Hi Herve, Thank you for the pointer. What are the steps for reverting to AICPUPM ? Do I need to do that on the E6440. I want to upgrade to 10.5.4 but am afraid to mess up the current setup. Thank you

My E6440 has been running flawlessly using the installation guide here. Is it worth it to upgrade to 10.15.4 ? Also I have question regarding the clover package to use. There seems to be two providers. https://github.com/Dids/clover-builder/releases https://github.com/CloverHackyColor/CloverBootloader/releases The install guide uses 'Dids'. But the last version from 'dids' is r5103. The latest seems to be r5107 Thank you for any pointers.

Hi, Just got my old E6400 working with the instructions above. Has anyone got the Dell DW1397 wireless card working with this setup ? I am running Yosemite 10.10.2. Thanks for any help/pointers.

Hi, First post here, I have been using the guide in this thread and have great successes with my E6400. I am currently running ML 10.8.2 without issues except until today. I came across an issue that I don't think it has been brought up before but I hope someone can help. I installed both Vmware Fusion 5.01 and VirtualBox 4.2.1 on this laptop and tried to setup "Bridge Network" on one of my VM. That did not go well. First, I cannot get any dhcp lease from my dhcp server, I tried to setup manual IP, that works but I cannot ping the gateway or any host on the network other than the IP address of the ML host. If I set the Network Interface to NAT, I can ping the gateway and other host on the network without issues. Hope someone has seen this before and provide some guidance to resolve this issues. Thank you.
