Re: [Elecraft] DVI connectors with an P3SVGA

2012-03-24 Thread Dave New
Beware of HP docking stations at swaps, since there is a rash of those 
with fried DVI outputs.  At my work QTH, we recently moved from Dell 
laptops (poor quality) to HP laptops (possibly even poorer quality, but 
cheaper, if that's even possible), and DVI outputs from the HP docking 
stations started failing left and right.  For a while, the IT folks were 
replacing the HP docking stations en masse, but finally gave up on it, 
since the replacements were all starting to fail, also.  My docking 
station bit the dust last week, crippling my productivity since I rely 
heavily on using Windows 'extended desktop' so that I can easily copy 'n 
paste between program windows, since Windows insist on popping a window 
that gets input focus automatically to the top of the Z order on the 
screen (I miss Unix/Linux at work, I really do).

Their solution?  They now replace the DVI cable from on failed docking 
stations to the external display with a VGA cable.  Issue solved.  What 
a crock.  The external display is definitely now not as crisp.

So, if you see piles of HP docking stations in the flea markets, you 
will know why, and if DVI connectivity is important to your particular 
setup, you will steer clear.

Thanks for all your inputs on this.

My PC has only one video out and it is VGA. Studying the pictures of DVI 
connectors, the DVI input on my monitor is DVI-D so it will not accept DVI 
analog. 


I could add a video card with DVI output to my PC. However, searching the 
internet it appears there are inexpensive cards with DVI but they are for 
DVI-A. The cards with DVI-D output are more expensive.

So probably a new monitor with the inputs I need is the best way to go.

Just had a quick look at Tigerdirect (Canadian version) and they had 
plenty of adapters that were under $20all with VGA  some with DVI-d 
and DVI-Inone with DVI-a   at least for the ones that showed the 
connector in the photo.   also many of these also had HDMI as well.
these were PC express   there was also some agp cards that had DVI-I   
for just over $30still cheaper than a monitor.  based on this you 
should be able to easily find one at your local computer store that will 
work for you.  I am sure I have one or two AGP cards in my junk box.
if your DVI cable is DVI-D  it will fit the DVI-I and will work for 
digital input.

Bill K9YEQ, and lo! it spake thus:

 I have found I am able to feed analog signal from a DVI PC output

Right, but that's orthogonal.  Many cards with DVI can provide analog
out through the port, yes.  My point though is that I'm not aware of
any that don't provide digital (and I can't imagine what the point of
such a thing would be).


Or, more verbosely: The point of the DVI connector is to give a
digital output (hence the Divital Visual Interface ;).  For hysterical
raisins, there are pins on the connector that can also carry a
VGA-style analog signal.  So a DVI port can theoretically give you
analog, or digital, or both.  Or neither, I guess, but then it's just
for show  ;)

But there'd be no point in having a card's DVI port only speak analog,
and not digital; you might as well just put a DE-15 and be done with
it, as it gives you exactly the same capabilities (and the DE-15 will
be higher quality than the analog pins over DVI).  So it's a pretty
safe assumption that any video card with a DVI port is capable of
talking digital out of it; it may also talk analog (I know some do; I
don't know whether it's common or rare lately), but it's staggeringly
unlikely for a card to do (analog  !digital).

I'm not sure what card he's finding that has a DVI-A (only analog)
connector on it.  I suspect he's just misreading or something's
mislabelled, as there's no real point to that as a port on a card
(you'd generally only find it as a cable, or possibly a monitor-side
port).  Every DVI card I've ever seen has a DVI-I port (physical pins
for both A/D; whether it actually has analog signal on them I don't
know).

Re: [Elecraft] DVI connectors with an P3SVGA

2012-03-23 Thread Joe Ford
My one monitor has 2 inputs, one is the standard VGA and the other is a DVI-D 
(3 rows of 8 pins and 1 flat pin). So if I had a card with a DVI-D out I should 
be able to connect the PC to the monitor. I googled DVI-D. One of the hits 
was Amazon and it showed many cards but they only described the outputs as DVI, 
not DVI-D or DVI-A. And the photos did not show the connector up close. I was 
just guessing that because they were cheap they were analog but I had no way of 
knowing for sure. 


There must be monitors with DVI-A female (and only DVI-A) otherwise why have 
such a connector. When I ordered a VGI to DVI cable what I was sent was the 
VGA/DVI-A cable which is of no use to me. My PC which is several years old has 
only the 15 pin VGA output. If my monitor had a DVI-I input, which it doesn't, 
it should work with this cable, because it will work digital or analog.. 


My PC has the 15 pin output and the P3SVGA has that connector also. If I'm 
going to have only one monitor it will have to have 2 of the 15 pin inputs or 
one 15 pin and one DVI-A.
Or I'll need to go to 2 monitors.

Thanks for the advice.

Joe Ford, and lo! it spake thus:

That's the general use case for DVI-A connectors; going from the DVI
controller end to a VGA on the device end.

A general purpose video card will practically always have a DVI-I
(both outputs) socket on the back.  Into a DVI-I port, you can plugin
a DVI-A plug (passing only analog), a DVI-D plug (passing only
digital), or a DVI-I plug (passing both).

Both electrically and physically, the DVI-I is a superset; both itself
and the two more specialized variants can plugin to it.  Hence, why
the card will almost certainly be DVI-I.  And since there's not much
point using a DVI port if you're only going to output analog and no
digital, you can pretty well assume any card is putting out at least
the digital side.  Certainly anything in the last 5 or 6 years, since
LCD's are the lion's share of the market.  My video card is something
like 7-8 years old, and it has 2 digital-out DVI ports on it.


If you're going to a LCD, you pretty well always want a digital in.
Even when they take analog (as in a 15-pin VGA), they just turn that
into digital internally, since that's how it controls the pixels.  So,
a LCD will generally have a DVI-D port.  Maybe occasionally a DVI-I,
just for the extra connector compatibility (you can put a DVI-D plug
into a DVI-I port, but not vice versa), but the analog side will
probably not be connected.

On the other hand, a CRT needs that analog steering; that's how it
moves the beam and turns it stronger and weaker.  There may be some
CRT's out there with a digital in (I haven't seen any, but It Stands
To Reason(tm)), but if so, they're going to have to convert it into
analog internally to be able to display the signal (sorta the opposite
of putting analog into a LCD).  So, a common config for this is a
cable with a DVI-A on one side, and a DE-15 VGA connector on the
other.  Possibly, it may have a DVI-I connector on the device side
instead, and only hook up the analog pins, but usually not, since that
cuts down on the ports it can hook into (it could only hook up to a
DVI-I, not a DVI-A).


I doubt there are many device-side DVI-A ports.  There're sure to be
some, for weird special needs, but I'd definitely expect them to be
niche cases.  If something really wants analog, it would just use
DE-15 since that's already all over the place on analog eq.  There may
be some use of device-side DVI-I, for devices that could take either
digital or analog.  But then, it's common enough to just have both a
DVI and a VGA like on your monitor, so that's probably uncommon too.


 My PC which is several years old has only the 15 pin VGA output. If
 my monitor had a DVI-I input, which it doesn't, it should work with
 this cable, because it will work digital or analog.

If it did, yah.  I'd expect such monitors to be rare though; having a
VGA port to handle an analog in is still so standard, there's probably
not much point in adding the complexity of trying to take analog over
the DVI too.


 I was just guessing that because they were cheap they were analog
 but I had no way of knowing for sure. 

I'd bet they're all just digital.  It's _more_ work to turn it into
analog, after all.

For a ref, look at the Radeon 5000 series at Newegg:

http://www.newegg.com/Product/ProductList.aspx?Submit=ENEN=17709%20600030349%2067320IsNodeId=1name=Radeon%20HD%205000%20series

The 7000 series are mostly out now, so the 5000 is almost 2 gens back.
The 4000's are old enough they're actually often more expensive.
There's a good selection of 5450's under $30 shipping and all, and
they all have at one analog (VGA) and 2 digital (DVI and HDMI) outs.
You could poke around for a 4/5000 on ebay maybe, but I'm not sure
you'd actually save much in the end at those prices, and you wouldn't
get as good a return policy.


 My PC has the 15 pin output and the P3SVGA has that connector also.
 If I'm going to have only one monitor it will have to have 2 of the
 15 pin inputs or one 15 pin and one DVI-A.

You could try getting a KVM switch and just switch the one 15 pin
between the two.  But a cheap KVM will fuzzy the picture all up, and
an expensive one would be expensive.  It'd be way cheaper and you'd be
way happier spending 30 bucks on a video card.


 Or I'll need to go to 2 monitors.

Well, any excuse...   8-}

I made no claims, just that with some monitors and card the adapter works.
To be safe, just use a monitor with a VGA connector and get past all this
probability for problems.  The adapters can be very cheap, but if you happen
to have one that works with an earlier DVI/VGA monitor, try it before
investing. The safest bet is a dual vga/dvi card out output video card, or
dvi/vga input on the monitor.  The adapters or cables are truly a crap
shoot.  Anyone who builds or works on desktops would probably tell you that.

[Elecraft] DVI connectors with an P3SVGA

Re: [Elecraft] DVI connectors with an P3SVGA

2012-03-22 Thread Mike K2MK
Hi Joe,

Save your money, it won't work. My understanding is that DVI is a digital
format and the SVGA card is an analog format. So while you can get cables
and and/or adapters that will fit they just won't work. I haven't received
my SVGA card yet but in preparation I conducted an experiment with my PC
using a DVI adapter. I connected the VGA output of the PC to the DVI input
of the monitor using a DVI adapter on the end of the VGA cable. The monitor
won't recognize the analog signal on the DVI input.

So here's what I did. My PC has both a VGA and a DVI output. I used the VGA
output from the PC to drive the primary monitor. I then used the DVI output
from the PC to drive the secondary monitor. I then put a VGA cable on the
other input to the secondary monitor and have it in position to attach to
the P3 as soon as UPS drops off the card. I only use the secondary monitor
to display the VE7CC cluster program and there is a front mounted button on
the monitor to switch between the two inputs.

If your PC has a VGA and DVI output you can do exactly what I did with your
single monitor.

The only difficulties incurred were trying to get the PC display program to
properly identify monitor number 1 and monitor number 2. I fiddled with it
for quite a while but I don't remember what I did to get it right. You
should have no problem with only one monitor.

(As an aside, you can get very inexpensive DVI adapters in all of the
various formats on eBay by way of China or other Asian destinations).
Usually for under $3.00 including shipping).

Re: [Elecraft] DVI connectors with an P3SVGA

2012-03-22 Thread Tom Azlin N4ZPT
I discovered the same thing. Guy at the local small computer shop said 
do not bother. So I checked my weather computer to discover it had a DVI 
connector in back then just bought a DVI-D cable which the display card 
recognized fine. then used the now empty VGA connector/cable with the 
P3. Works nicely.

 Hi Joe,

 Save your money, it won't work. My understanding is that DVI is a digital
 format and the SVGA card is an analog format. So while you can get cables
 and and/or adapters that will fit they just won't work. I haven't received
 my SVGA card yet but in preparation I conducted an experiment with my PC
 using a DVI adapter. I connected the VGA output of the PC to the DVI input
 of the monitor using a DVI adapter on the end of the VGA cable. The monitor
 won't recognize the analog signal on the DVI input.

 So here's what I did. My PC has both a VGA and a DVI output. I used the VGA
 output from the PC to drive the primary monitor. I then used the DVI output
 from the PC to drive the secondary monitor. I then put a VGA cable on the
 other input to the secondary monitor and have it in position to attach to
 the P3 as soon as UPS drops off the card. I only use the secondary monitor
 to display the VE7CC cluster program and there is a front mounted button on
 the monitor to switch between the two inputs.

 If your PC has a VGA and DVI output you can do exactly what I did with your
 single monitor.

 The only difficulties incurred were trying to get the PC display program to
 properly identify monitor number 1 and monitor number 2. I fiddled with it
 for quite a while but I don't remember what I did to get it right. You
 should have no problem with only one monitor.

 (As an aside, you can get very inexpensive DVI adapters in all of the
 various formats on eBay by way of China or other Asian destinations).
 Usually for under $3.00 including shipping).

Re: [Elecraft] DVI connectors with an P3SVGA

DVI connectors will do both analog and digital, if the connected device 
supports both.  My first generation Mac Mini had a DVI connector which I used 
with a DVI cable to a digital monitor.  It also came with a DVI-SVGA adapter 
which I later used with an analog monitor.

Re: [Elecraft] DVI connectors with an P3SVGA

2012-03-22 Thread david Moes
There are different flavours of DVI
DVI-a   is analogue and can be adapted to VGA
DVI-d  is digital only and cannot be adapted to vga without an expensive 
($150+) adapter.
DVI-I  is integrated digital and analogue. and can be adapted to VGA 
with a basic adapter.

if you Google DVI types and look for images in your results there are 
plenty of pictures showing how to tell what you have.
its quite possible that your monitors  DVI connector could be DVI-I   my 
PC in the shack has VGA out only and is connected via VGA to DVI cable 
to the monitor

Re: [Elecraft] DVI connectors with an P3SVGA

Hi Bob.

I have a lot of DVI-to-VGA adapters but they turned out to not be DVI-D 
(digital only) but rather DVI-I (both analog and digital) to VGA. There 
is also DVI-A (analog only) connector. My monitor has a DVI-D and a VGA 
connector so the DVI adapters I had and could find would not fit.
