HDMI Adapters
Advice please. I have a 27" monitor which connects only via HDMI. My PC
has an NVIDIA GTX 750 2GB video card with mini-HDMI, DVI-I, and DVI-D adapters. What's my best option for an adapter to connect the two with the least (if any) performance hit? -Walt |

The mini has the same number of pins as regular but smaller and with a different pin arrangement. 'Regular' HDMI plug is called type A and mini is type C in the wp article which also describes the pins. They make cables which are A-C, or if you already have an 'A-A' cable there are A-C adapters. This amazon ad page which shows both happens to show it a little cheaper to buy the whole cable than the adapter https://www.amazon.com/Cable-Matters.../dp/B004PW1XRS -- Mike Easter |

NVIdia says: One Dual Link DVI-I, One Dual Link DVI-D, One mini-HDMI I see discussions of people asking 'Why?' (not hdmi). Some of those discussions say the oem included an adapter in the package. One answer said that by the time they put those DVIs there wasn't 'room' for a regular hdmi which is just a few mm more, but those mm/s make a difference. -- Mike Easter |

Looking at the card in the flesh, there is not a mm to spare... I vote for the 'room' answer. Thanks. -Walt |

What's my best option for an adapter to connect the two with the least (if any) performance hit? -Walt The HDMI is still your best bet. That card might be HDMI 1.4, but the NVidia site isn't giving away the info about it. Some other models, they're a bit more forthcoming about that aspect. It should be able to do 2560x1600 @ 60Hz at least. Some of the other modes are "theater modes". It will do higher resolutions at 30Hz or 24Hz, and those aren't options for working in Microsoft Word. 30Hz and 24Hz are excellent for videos playing at those movie rates, as it means no "pulldown" step when driving the screen. The DVI will also do that value, assuming it is dual lane (DL-DVI). ******* Just for giggles, the most kickass 27" panel in a quick search, is this one. 5120 x 2880 , which would be well outside the HDMI standard your card likely has. This is why it helps to know the Make and Model Number of the LCD monitor. The 3840 x 2160 (4K) monitors would similarly, not be a good match for your video card and its choice of HDMI standard. You might end up using a non-native resolution choice if driving this with GTX 750. https://www.newegg.com/Product/Produ...9SIAFJ86WT2207 There are also 2560x1440 (2K) and 1920x1080 monitors at the 27" diagonal size, and HDMI and DVI could handle both of those. There is a table here, 50% of the way down this page, which relates HDMI standards number versus resolution/refresh. https://en.wikipedia.org/wiki/HDMI The only thing I have against HDMI, is the lack of a positive retention feature (cable lock). Some early HDMIs had a tendency to fall out. I haven't had a problem with the one I've tested here so far. The DisplayPort, by comparison, has a plastic "release" button, implying there is a lock feature. I have to depress that, before I can remove the cable from the card. I use active adapters from those two standards, to run the real monitors. I also own multiple active adapters, so when the video driver goes nuts in a certain OS, I can keep plugging in different adapters until I get a picture, then bring up the Display panel and "fix it again". Grrr. This happens coming out of Sleep, amongst other things. If you see a black screen coming out of Sleep, try moving the monitor to another connector, because there is a chance the signal is coming out on that. And that's what I'm doing, when I switch active (powered) adapters, is "looking for where my damn screen went". The impedance and EDID capabilities of the hardware, are supposed to make an end to this behavior. Yet, there we are, looking at a black screen, when a session I was working in, is hiding under there. Paul |

This has mini on one end, and regular on the other end. https://www.newegg.com/Product/Produ...9SIA6ZP3K31553 Doing it using one of these, might lead to a looser fit. Too much stuff jiggling around. To work with the prevalent male to male cables, these adapters are male on one end, and female on the other. "Rocstor HDMI to Mini HDMI" https://www.newegg.com/Product/Produ...9SIA6ZP8U88234 Paul |

Thanks. That's a lot to digest but it will be interesting to see how it shakes out... Is your HDMI screen an exotic one, or a more ordinary one ? See if the box mentions native resolution value. If the monitor has DL-DVI on it, I suppose that's a hint it is an ordinary monitor. An "extreme monitor" with a high native resolution, might use only (two) HDMI or a DisplayPort. The Wikipedia article on DVI, tells you how far single link DVI goes, and how far dual link DVI goes. The "appearance" of dual link, a full array of DVI pins, does not "guarantee" the hardware is dual link. But if the Display control panel has already shown 2560x1600 operation at 60Hz, there's a good chance the DVI uses is DL-DVI. The Wikipedia HDMI article has a table half way down the page, that defines a few data points for HDMI operation. Occasionally, a little interpolation is required, to work out what other values might work. For example, I see an entry like this. Maybe I own a 2560x1600 monitor at 60Hz. Will it work ? 2560 × 1440 75Hz 7.09 Gbit/s I note that since the refresh rate I will be using is lower, that gives more headroom on resolution. 1440 * 75/60 = 1600 which means 2560x1600 @ 60Hz refresh, would also be 7.09Gbit/sec.

I'd buy the adapter though. That way you can buy or use current cables. Al |

Also for some strange reason a tablet might come out with a mini-HDMI port like what I had with my 1st tablet, an ole ACER, which had the mini-HDMI port. |
