I can only use two of the three monitors at a time.

This is a Win7 Pro desktop PC with a GEForce 210 video card, with a VGA, HDMI, and DVI connector.  The primary monitor is connected to the HDMI port.   I have a DVI-VGA converter plugged into the DVI port.  If I connect all three monitors, one of the non-primary monitors will be black.  The 3rd monitor does appear on the Windows Screen resolution setup screen, but its icon is darker grey, and the Resolution and Orientation fields are greyed out.  The Multiple displays field says Disconnect this display, and no matter what I change it to from the dropdown, it ignores me and goes back to Disconnect this display.  

The Nvidia control panel only sees two monitors at a time, i.e. never three like Windows does, but if I disconnect one of the side monitors, then the Nvidia control panel "sees" the other side monitors and displays its model name correctly.  Note that I just now downloaded the latest driver for the GEForce 210 and rebooted.

Is this card incapable of running three monitors, or am I doing something wrong?  TIA

The customer wants to use three new monitors for the office computer, for typical office apps.  All it has on the motherboard is one VGA and one DisplayPort, so I wanted to get a video card that would support all three monitors using the HDMI and/or DP ports on the monitors--which is all they have, being large and new.  But every reasonably priced video card I look at has VGA, DP, and DVI--and of course VGA and DVI do me no good in this case.

Is there such a thing as a reasonably priced video card that has all DP and/or HDMI outputs?  Low profile would be even better.  Again, I'm not looking for hi-res graphics or gaming features.  Rather, I'm just trying to get access to three "modern" video ports for this PC.  

Or, should I buy three USB HDMI video adapter dongles--and expect that to look good and for Windows 7 to manage all three screens properly?  TIA

Hello and Good Afternoon Everyone,

          I am wondering if it is possible to locate and purchase a handheld instrument that can use laser light to access measurements like height, width, and depth and transmit this information digitally back to its display.  I am not sure if such a device exists commercially, but, I know if it does, someone on this forum would definitely know for sure.  

          Any shared thoughts or possible leads regarding this interest will be greatly appreciated.

           Thank you

Distributed processing, space telescopes and super-computer speeds

I read that IBM sold a super-computer called Summit in June 2018 that could perform 200 Trillion transactions per second.

Curious...

How many average Windows laptops are need to rival that kind of power?

And if that average Windows laptop is used in a business environment, what kind of hardware utilization is there to:
1) Run Windows
2) Perform ordinary office uses, like email, word processing, running a virtual terminal?

Secondly, what can you tell me about the processing power of a distributed model where thousands of PC's perform calculations when it detects idle time?

There is a famous space telescope which does this. Please remind me of the name of that system.

Thanks

NXP LPC11E68JBD48E Microcontroller I2C1 is Master.   I2C1 is in Master Transmitter Mode.
I2C1 peripheral is in chapter 13.  http://www.mouser.com/ds/2/302/UM10732-315822.pdf
NXP PCAL6416A I2C 16-bit I/O Expander is Slave. https://www.nxp.com/docs/en/data-sheet/PCAL6416A.pdf.

Master reads one byte from slave port 0.  On one board all Eight bits are logic 1's as expected.  On the other board Seven bits are logic 1's as expected
but bit 2 is logic 0.  The input pin connected to bit 2 is pulled up to 3.3V but it's logic 0 on I2C data bus.  Why?

                              D7 D6 D5 D4 D3 D2 D1 D0
Expected              1    1    1    1    1    1   1    1
One board           1    1    1    1    1    1   1    1
Another board    1    1    1    1    1    0   1    1

Explanation/Questions on attached scope screenshots:  Master sends slave address 0100 001(A6-A0), followed by write bit(logic 0).  Slave responds with ACK(logic 0).
Then, master send command byte 0x00(read byte from Input port 0).
Master sends start bit, followed by slave address, followed by read bit(logic 1).  Slave sends ACK.
On one board, slave send 0xFF as expected.  On other board, slave sends 0xFB, not expected. Master follow with a NAK.  Slave pulls data bus low before the stop
condition?  Why slave pulls data bus low?

The primary question is why is bit 2 logic 0 on the I2C bus when it's pulled up to 3.3V ?

Are we setting the I2C device properly?
INT pin(active low) is floating.

Hello and Good Morning Everyone,

         I am wondering if it is possible for new and unused external USB flash drives to become defective or bad over time.  The reason I ask is because I am considering buying a pack of external USB flash drives for quick and convenient data backup and restore purposes.   Realizing there might be some new ones which might not get used for several months or even a year, I do not want to take a chance on them going bad simply because of non-use.

         Any thoughts shared to this question will be appreciated.

         Thank you

We are following instructions to burn to disc one (1) mp4 video. The first program did create the audio_ts and video_ts folders
In the image you see a mention of a file system. It also mentions using your own favorite burning software. Efforts to burn these two files (audio_ts and video_ts has failed.
What is this file system?
What other programs can you suggest. It's one video to play before a group of people so we need the video to play on a table top player and I try not to pay for a program since it's only one video needed. Thanks.

The burner recommended along side the above program that created the file structure, was to locate the folders and move them to another folder. Here they are and the chosen burner is getting errors when trying to just add the folders to the burning program.

How Much Work from the Fastest Super Computer in the World?

I read that IBM delivered Summit in June 2018 to the Dept. of Energy which, at that time, was the fastest in the world. Any faster one since?

I read 200 Trillion computations per second.

IF Watson were to run on that machine, how many computations might there be for one question on Jeopardy? It's an impossible question to ask, but I am just trying to get a scale that I can compare to that 200 Trillion capacity in one second.

And when it comes to latency caused by waiting for some external process, consider that zero.

This is logical since, since the calculations for to determine the best answer might require many seconds, yet I want to know the aggregate amount of computations  needed so I can guesstimate how many such average answers such a system (Watson + Summit) might one second's capacity consist of.

Thanks.

Getting these on every startup. No new hardware or software installed.

I'm considering the purchase of at least 40 ThinkCentre Tiny-in-One units.

M720 has Core i5 8400 1.7Ghz  verses M15 2nd Gen AMD Ryzen 5 Pro 2400GE 3.2Ghz  

$4000.00 dollar difference in overall price.

Would $4000.00 be worth it or a waste and why?
