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 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.

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.

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.
