Two monitors viewport and hdmi for mac tv#
While you can go from a displayport to VGA monitor with a basic adapter(displayport provides power, where VGA doesn't), I don't believe it's possible (and the your link mentions) that its not possible to go from VGA to DisplayPort, what's powering the conversion of the signal?įor analog VGA/YPbPr and dual-link DVI, a powered active adapter is required for compatibility and does not rely on dual mode. Look at the port diagram, you need pins C1-C4 for the analog signal, without those, you've got nothing but a digital signal. Example, a DVI-D doesn't pass through analog signals, it's digital only. Only certain DVI pinouts allow for analog signal conversion with a pin change. So much esoteric stuff in those articles. (Article indicates passive DP/HDMI adapters are possible, so I don 't know why a passive VGA>HDMI wouldn't be possible but I've never seen one)Īny case, I'm just saying that analog to digital doesn't necessarily require an active converter. **If I remember correctly**, displayport actually can be run from VGA without an active adapter because displayport was based on DVI. HDMI is not engineered this way, so you do need an active adapter.
(Isn't a true digital signal really just a square waveform?) VGA is an analog signal, but the DVI interface is a digital interface which was engineered in a way to be electrically identical to a properly functioning VGA signal, so only a pinout change is needed. I've used active HDMI to VGA since HDMI has the opposite issue, and it worked surprisingly well, but I wouldn't want to use it permanently, I don't trust stuff like that not to burn out.Įssjae That's not entirely true. The active adapter externalizes the analog to digital conversion, and it will probably need a power source - probably a USB port, to power it. They probably just don't have the A to D hardware in the monitor and really didn't gear the thing for people putting the adapter on the other end.Īs Josh_The_Geek pointed out you will probably need an active adapter if you want to use a VGA port. Long story short, it's cheaper to go all digital from a manufacturing perspective, no more A to D conversion, and the picture looks better anyways. VGA on the other hand is analog and requires extra equipment on the monitor side to convert analog to digital. My guess is that DVI-D to Display port with work, HDMI to Display Port, and obviously Display port to Display port because they're all digital. On the monitor side however, it sounds like the monitor itself may be pure digital. So what I'm trying to find out is if there is another adapter i could use to get the second monitor to connect and work properly.ĭisplay port to just about anything else on the computer side works because the computer is built to handle both the analog and digital output needed to make it happen, it's part of the standard.
The same results so its not the monitor that is having issues. I also tested the cable on the monitor that was already working and had when i look in the display settings on the working monitor the second monitor shows up as a generic PNP monitor and i can move my mouse to the second screen but ti doesn't actually show anything on the monitor itself. we got a VGA to display adapter from amazon that said ti would work in this kind of situation (where the vga port is on the computer and the display is on the monitor) but the monitor will not display anything. i was able to get one of them working on the HDMI port, but am having trouble with the second monitor on the vga port. the computer itself has one HDMI and one VGA port. the monitors only have HDMI, and Displayport ports to work with. Recently had a user purchase 2 Samsung C32F391 Monitors, and I'm trying tog et them to work with his current workstation.
