General / Miscellaneous / Apple first used DisplayPort via Thunderbolt for 4k displays.. not HDMI

Apple first used DisplayPort via Thunderbolt for 4k displays.. not HDMI
The earliest Mac models to support 4K resolution via their built-in ports were the Mac Pro (Late 2013) and the MacBook Pro (Retina, Late 2013).

They supported 4K output through their Thunderbolt 2 ports, which are also DisplayPort 1.2 compatible. This allowed for connections to 4K displays via Mini DisplayPort to DisplayPort or Mini DisplayPort to HDMI adapters.

hence the thunderbolt to displayport adapters:

below is some further information on displayPort versions:

DisplayPort 1.2 was released in January 2010. It was officially ratified by VESA in December 2009. This version significantly improved upon its predecessor, DisplayPort 1.1, by doubling the data rate and introducing new features like Multi-Stream Transport (MST) for daisy-chaining multiple monitors.

DisplayPort 1.2, introduced in 2010, significantly improved upon previous versions by doubling the data rate to 17.28 Gbit/s, enabling higher resolutions, refresh rates, and color depths. It also introduced features like Multi-Stream Transport (MST) for connecting multiple monitors and support for stereoscopic 3D.

DisplayPort 1.2 supports various refresh rates depending on the resolution. For example, it can handle 1080p at 240Hz, 1440p at 144Hz, and 4K at 75Hz. It also supports 5K resolution at 30Hz. DisplayPort 1.2's maximum total bandwidth is 21.6 Gbps, which enables these refresh rates.

Specific refresh rates supported by DisplayPort 1.2:
1080p (Full HD): Up to 240Hz.
1440p (Quad HD): Up to 165Hz.
4K (Ultra HD): Up to 75Hz.
5K: Up to 30Hz.

DisplayPort 1.2 also introduced features like support for multiple independent video streams (daisy-chaining), improved audio bitrates, and stereoscopic 3D. It also added support for the Mini DisplayPort connector.

DisplayPort 1.4 was introduced on March 1, 2016. It's a significant update building upon DisplayPort 1.3, offering features like Display Stream Compression (DSC), Forward Error Correction, and enhanced audio capabilities.

DisplayPort 1.4 supports a wide range of refresh rates and resolutions,
including 8K at 60Hz and 4K at 120Hz without compression.
With Display Stream Compression (DSC), it can achieve 8K at 60Hz with HDR and 4K at 144Hz.
It is also capable of supporting 1440p at 240Hz.

Specific Refresh Rates and Resolutions supported by displayPort 1.4:
8K: 7680x4320 @ 60Hz (with DSC)
5K: 5120x2880 @ 60Hz (without DSC)
4K: 3840x2160 @ 120Hz (without DSC), 144Hz (with DSC)
1440p: 2560x1440 @ 240Hz (without DSC)
1080p: 1920x1080 @ 240Hz

DisplayPort 1.4 also supports HDR and is backward compatible with older DisplayPort devices.

1990s / Re: Power Supplies for Old School Daws

most UPS batery backup systems also feature surge protection.. i would say find a old ups (uninteruptable power supply) even if the battery is no longer functioning it may serve the purpose of cleaning + protecting the power? just an idea

Haswell (Jun 2013) / whats the oldest motherboard that can boot from nvme?

« Last post by chrisNova777 on July 20, 2025, 01:07:30 AM »

The oldest Intel desktop platform that can natively boot from NVMe is the X99 (Haswell-E) chipset. This platform was introduced in 2014 and is the first Intel desktop platform to feature M.2 slots, which can support NVMe SSDs. The X99 chipset was released in late August 2014, according to Wikipedia. Specifically, the compatible Intel Core i7 "Haswell-E" processors were released alongside it, also in late August and early September.

https://www.msi.com/Motherboard/990FXA-GAMING/Specification
The MSI 990FXA GAMING motherboard was the first AMD motherboard to offer NVMe support. It was released in May 2015 and specifically supported NVMe devices as a primary storage option under Windows 7 64-bit and Windows 8.1 64-bit, including NVMe booting. This motherboard also featured USB 3.1 ports and was designed for AMD FX, Phenom II, Athlon II, and Sempron processors with an AM3+ socket.



The first generation of desktop motherboards with official NVMe support for booting were Intel's 5th generation (Broadwell) on the X99 chipset and some Z97 chipset boards, according to Level1Techs Forums. These boards were typically high-end desktop (HEDT) and offered DDR4 memory support. While some older systems could be modified with custom BIOS to boot from NVMe, these were the first to offer official support.

Early NVMe Support:
NVMe, or Non-Volatile Memory Express, is a protocol that allows for much faster data access speeds compared to traditional SATA. Early NVMe drives were often used on systems with PCIe adapters or modified BIOS to enable booting.

Official Support:
The introduction of NVMe support on X99 and some Z97 motherboards meant that users could boot directly from NVMe drives without needing to modify the BIOS or use adapters.

Z97 chipset motherboards were introduced around May 2014, supporting Intel's 4th, new 4th, and 5th generation Core processors (Haswell, Haswell Refresh, and Devil's Canyon). These motherboards were designed for high-performance PCs, gaming rigs, and multimedia centers. Key features included support for SATA Express and M.2 storage interfaces, offering faster data transfer speeds.

The first Mac to feature NVMe (Non-Volatile Memory Express) was the 2016 MacBook and MacBook Pro. Apple adopted NVMe to improve storage performance and power efficiency in these models.

havent heard that name energyXT in quite awhile.. i think i first remember hearing about it around 2006? (could be wrong?) i think i read about it in magazines i used to get at indigo chapters bookstore etc back when reason was still somewhat of a new product.

just did a google ai search: EnergyXT was originally released in 2007.

sounds about right.

OsX86 Hackintosh (Intel / AMD) / quick hackintosh fix for undetected audio ports, add clover boot arg "alcid=1"

« Last post by chrisNova777 on July 19, 2025, 10:37:47 PM »

if ACLID=1 doesnt work try different numbers

theres other boot args related to ALC listed here
https://elitemacx86.com/threads/common-boot-args-for-macos-clover-opencore.937/

alcid=xx   
Sets Layout ID for AppleALC.
The xx represents the layout ID for your codec.

-alcoff   
Disables AppleALC

-alcdbg   
Enables debug printing.
Requires DEBUG version of AppleALC

-alcbeta   
Enables WhateverGreen on unsupported macOS versions (macOS 13 and below are enabled by default).
Usually relevant for newly announced macOS.

alcverbs=1   
Enables alc-verb support.

alcdelay=xxx   
Adds delay in AppleHDAController.

Useful where the hardware isn't initialized in time for AppleHDAController which results in no Audio output.
The xx represents the delay in ms.
Must not exceed 3000ms.

alctcsel=1   
Fixes Audio on macOS after rebooting from Windows.

doesnt hurt to update your whatevergreen and lilu in the clover configurator app...
(use the dropdown to select where your files are in your clover folder in efi folder)

i think i also downloaded AppleALC via the cloverconfigurator (adding it as it didnt exist on my efi folder before that)
