Your Newer M1 Mac has a more advanced DisplayPort, which supports more advanced HDMI capabilities when used with an adapter, and can support 4K at 30Hz directly on one cable, so that is offered as an option. My notebook has HDMI version 1.4 and maximum monitor resolution of 1920 x 1080 (HD). The display has two HDMI inputs for exactly this scenario. I would like to use my notebook to drive a 4K monitor. You are expected to connect an additional HDMI cable for the second half, and turn on the Picture-By-Picture feature in the display to put the two halves back together. Click the Hardware tab and then click Device Manager. To check your computer’s capabilities for 4K, I recommend using the following steps: Go to the Control Panel. Since it cannot produce ONE signal that can drive the entire display, the lower resolution offered is intended to drive one half of the display. You can check whether your computer can run 4K or not on your own. 4K, or UltraHD refers to a class of high-definition displays and video. Youll also need to think about whether your computer can drive a 4K monitor, particularly if its a laptop. 4K computer displays require hefty hardware upgrades. If you dont have the space, you might want to use a VESA mount instead. Older, less taxing games will be more accommodating. These often take up a significant amount of vertical desk space. Nvidia’s GeForce GTX Titan X is the only single-GPU graphics card capable of playing games at 4K while maintaining acceptable frame rates. So on your "older" 2019 model Mac, lack of fancy new displayPort features limits its ability to support borderline HDMI features such as HDMI 4K at 30Hz. If you think you can spare the room on your desk, dont forget about the monitor stand. In 2013, VESA released the Dual-Mode 1.1 standard, which added support for up to a 300 MHz TMDS clock (9.00 Gbit/s bandwidth), and is used in newer DisplayPort 1.2 devices. Daisy-chaining-connecting a computer to a monitor, and then connecting that monitor to another monitor-is possible with HDMI 2.1. Because we're talking about 4K displays, HDMI 2.1 is more than adequate. This is equivalent to HDMI 1.2, and is sufficient for up to 1920 × 1200 at 60 Hz. That's enough to drive a 10K display at 60 frames per second in full 10-bit color. My graphics card is an AMD Radeon R9 380. I would like to use this as a computer monitor as well as a TV if possible, but I am experiencing some issues and I am trying to pinpoint the cause and solution. The original DisplayPort Dual-Mode standard (version 1.0), used in DisplayPort 1.1 devices, only supported TMDS clock speeds of up to 165 MHz (4.95 Gbit/s bandwidth). I just purchased the TCL series 4 4k 120hz TV. DisplayPort Dual-Mode ( DP++ ), also called Dual-Mode DisplayPort, is a standard which allows DisplayPort sources to use simple passive adapters to connect to HDMI or DVI displays.ĭevices which implement dual-mode will detect that a DVI or HDMI adapter is attached, and send DVI/HDMI TMDS signals instead of DisplayPort signals.
