One of my monitors is connected through a Display Port to HDMI adapter. Meaning that the graphics card outputs Display Port and the monitor takes HDMI.
I notice that the quality of the display is rather poor, and there is what looks like ghosting as you would find on an old analog television.
My question is, are there some display port to HDMI adapters that are better than others? Is this why some of them cost three times what others cost?
Or might there be something else wrong?

Best way is to begin by test with another cable / then test with another screen or tv. You will have more information to search wich part has a problem.

I have an OV2710 based USB camera (a low-light, as it should go inside a closed box). It is a UVC camera so no need for driver...
Connected the camera to a Win10 laptop - disturbing green shaded image (not fatal but all white/light colors are get greenish)
Connected to a Fedore 31 desktop - same...
Connected to a RPi 2/3/4 using a touchscreen - got a green-only shaded image... The image is clear and fast but green-only...
Anyone has experience with these kind of cameras? I just want to know if there is a way to fix that or should start to search for other camera (any suggestion to that direction is also welcome)..

I have a new PC, only a few months old. HP Envy Desktop 795 64bit running Windows 10 Pro.
Within the past month or so I am noticing what I can only describe seems to be USB interruptions. Every few minutes the Mouse and Keyboard 'freeze' up. If I'm watching a video it pauses for a second. It happens 2 or 3 times over a few seconds, then doesn't happen again for a dew minutes.
I'm not a hardware guy so I'm in the dark on this. I can provide any additional info if needed.
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.

You'll have to excuse me if I don't click on that link. Judging by the URL, it has absolutely nothing to do with USB issues.

Yeah, I saw that right after I hit Post.

Hi Gurus,
There has been a requirement to use Gemalto PC PIN Pad device in unsecured mode, Secure Pin Entry (SPE) not active. We have been trying our best to search online for any hint but unfortunately no luck yet. We can't contact Gemalto support because of no formal purchase of device yet (we are in R&D/evaluation phase) as Gemalto is requesting device information formally.
Any hint would be greatly appreciated.
Best Regards,
Asif

hello
i need the same as you. We need to be able to use it for loyalty purpose with.
Do you succeed to use it in an unsecure way to be able to get the pin back to a computer ?
thanks

Some PCIe devices cannot read more than 4 GB of address space without an additional driver or modified driver. In such cases, what limits how much memory they can read? Is it the memory controller? Is it the firmware of the PCIe device? Or is it something else? I don't think it is because of the device driver itself because PCIe devices can read or write to RAM without a driver. Someone said it is a 32-bit vs 64-bit issue but I do not understand why PCIe device can only address 32-bit.

I have purchased an ST8000NM0075 as this drive is compatible with my SAN system. However, this drive shipped with E001 firmware on it and I need it to run the LE OEM firmware from lenovo for this drive to work. I have been unable to find a way to flash the LE firmware onto a drive with E firmware. Is there anything I can do to make this work?

You would be much better served asking this on Seagate's forums than anywhere else.

Hello,
I am looking for ideas or even solutions to access the video or image stream of BOA SPOT cameras from Teledyne DALSA directly for further image processing. Teledyne has a SDK which unfortunately does no support this series of cameras. Only their pre-built software solution gives access but cant be integrated in other programs.
So far I didn't find any SDK or solution which does not rely on theis Sapera SDK (which doesn't support BOA)

Contact Teledyne and ask them to help you.

Been there, done that. They want to sell (more expensive) cameras which are supported by their SDK, not the other way round. Yet we cant just tell our customers "sorry, got to buy new cameras because the old one is the same but it has no official support"

Good day pals! Please I have been curious about this since I studied Computer Science. How can I build a hardware and control this hardware via my vb.net, c# or c++ application designed by me?
I know this question is vast but I only need guidelines on how to go about it probably the right keywords to use in searching please

Depends on the interfaces provided by your hardware.

Sorry, I don't want to use existing board. I want to build my own hardware from scratch. I can build the hardware cos I have knowledge but don't know how to communicate the hardware with software I have designed in any of the language

|
All microcontroller or CPU chip manufacturers have C compilers and libraries to communicate with the chips. There will be a lot of example code on their websites.

I have a PC that randomly shuts off after being on for more than 10 minutes.
A couple of times, I've been on the BIOS setup screen, and the hardware monitor has shown that the 12 volt supply drops below 11 volts to around 10.3 volts.
About two seconds after the voltage drop, the PC shuts off.
Is that enough of a variance that I can be confident it's the power supply causing it to shut off?

My first thought would be a bad power supply. If you're brave enough to open the case of the supply and not shock yourself on a charged cap, look for bulging capacitors in it.
It's also possible your motherboard may have a bad VRM stage or bad caps there too. Eletrolytic caps on a motherboard are not common any more. They tended to last about 5 years whereas the polymer caps that replaced them last for about 20+ years.

I'm going to replace the power supply, so we'll see what happens.
