It takes a tremendous field gradient to flip the magnetic domains on a hard drive. The hard drive can do it because the heads are so close to the surface and the gaps are so small. The magnets inside the drive's spindle motor and arm actuator produce a stronger field than will the external coil... but because of the motor designs, they don't put a high field ...

CRT monitors were commonly placed on top of desktop systems, with the lower parts of the tube just inches away from the hard disk. This has been done for a long time, and was common practice at least from the early 1980s right up through the early 2000s, and quite possibly longer. It became less common as tower PCs as well as TFT monitors became more common. ...

If CRT degaussing was a true risk to magnetic media—potentially exposing a system to data loss—then the original Macintosh would be a data loss disaster waiting to happen: Here is a pic of a clear cased Macintosh SE where you can see where the drives—including floppy disks—are located in relation to the CRT: Ditto with the Lisa: As well as the ...

Magnetic platters need far larger field strengths than an external degaussing coil produces. As a result, hard drives that are switched off are not likely to be affected from degaussing. Operating hard drives are an entirely different piece of cake since the writing (and reading) heads pick up and focus external fields. As a result, you can damage ...

Assuming you have a natively widescreen monitor: It might sound silly but you need more vertical screen real estate so the only temporary solution would be to rotate your screen by 90 degrees. Set the orientation to portrait and then reverse the resolution setting. In my screenshot I would need to set the resolution to 1200x1920 if I want to use portrait ...

Definitely not the hard drive. It could be the screen or the graphics card, but it's more likely the graphics card given that the computer spontaneously rebooted. Easiest way to tell would be to hook up a different screen and see if you get the same results. If you do, then it's the video card. Your only option is to replace it.

You need a card with two DisplayPort 1.2 outputs. DVI connections are not used by this monitor. Edit: this monitor connects with two DP cables and each cable appears as a single logical screen (there is no MST involved). So there is no requirement for the card to support more than two logical screens (which can be problematic for some Nvidia cards). Any ...

Because there is a reed switch in the laptop base and a corresponding magnet in the laptop lid. This is used to detect when the laptop is closed and so turn the screen off and potentially put the laptop into standby. This is quite a common feature in laptops.

Bash script, with timestamp, so when you show it to Comcast, you can point to exact times when it was down or flaky. ping comcast.net | while read pong; do echo "$(date): $pong"; done > ~/log.txt ...produces output like this: Thu Jun 5 00:23:54 CDT 2014: 64 bytes from 0.0.0.0: icmp_seq=235 ttl=55 time=61.848 ms Thu Jun 5 00:23:55 CDT 2014: Request ...

This is one of those old legends that never dies. If we travel far back into the mists of technological time (say, mid 1960s) we used tape. And we had these tape erasing machines that also did a good job straightening out the early colour TVs (I'm embellishing a lot here). Recording media back then was a LOT more sensitive to magnetic disturbance so it ...

With a strong enough degausser placed close enough to a hard drive, you can destroy the drive, but even with a very well aimed and strong one you have to be right on top of it. The coil on the CRT is wide, somewhat directed to the purpose it has, and on many computer monitors that whole area is shielded so not much gets out in any specific direction. You ...

From Wikipedia article on DVI: In single-link mode, the maximum pixel clock frequency is 165 MHz that supports a maximum resolution of 2.75 megapixels (including blanking interval) at 60 Hz refresh. For practical purposes, this allows a maximum 16:10 screen resolution of 1920×1200 at 60 Hz. To support higher-resolution display devices, the DVI ...

Happens sometimes with programs that use a fixed size of windows, that unfortunately happens to be bigger than your desktop/screen size. Likely a poor programming decision, or written for a different/old version where they assumed a minimum screen size, or some screen setting that could be changed. Sometimes the window could be resized and it might work ...

This is really annoying and even worse if the title bar is outside of screen, so you cannot drag it. The workaround I've been using is to install AutoHotKey and use EasyWindoDrag script. With that, you can drag the window or resize it by grabbing any part of window (using mouse), no only title bar or a corner. It works on every app I've tried. As an added ...

Assuming that the playback software itself has no performance issues, then the only difference between the 1:1 scaled version and the 2K/4K versions is that the latter will have to be downscaled to achieve the same presentation size. Depending on the downscaling algorithm of the player, you may see aliasing or softening/blurring effects. The video may also ...

You need to have two DisplayPort 1.2 connections in order to run at 5120x2880 with 60Hz refresh rate. A GeForce GTX 960 is currently the cheapest way to get proper support for 5K on this Dell monitor. As mentioned, as long as you only want to use it for everyday work (CUDA acceleration in certain Adobe applications such as After Effects or Premiere may ...

The metal case around a hard drive is effectively one big metal Faraday cage. An alternating Magnetic field couldn't effectively penetrate it whether it's diamagnetic, paramagnetic or a ferromagnetic metal due to the induction of eddy currents in the metal itself absorbing the external magnetic field. The bigger the AC current the warmer the case gets. Or ...

No, it's not possible. Both the on-board Intel HD4000 graphics and the Nvidia NVS 5400M have the same maximum resolution of 2560x1600. From the Intel spec sheet linked above, newer 4th generation Intel GPUs do support 4k (3840x2160 and 4096x2304) at 60Hz.

Yes, it is certainly possible. All you need is an Active adapter like Accell B086B-007B. As of mid-2014, it seems like there are a lot of 15 USD adapters that are advertised to support Ultra HD resolutions, but which do not appear to be as active as the active 25 USD ones by Accell, and none of those other adapters seem to be able to support Ultra HD on ...

This old forum thread may be helpful. Thomas51: After further research I found the root cause of the dual monitor problem. There is a task in the task scheduler called TMM (Microsoft Transient Multi-Monitor Manager). I disabled this task, and all seems to work fine now. Josh: Disabling TMM worked for me too, thanks a million! [...] But when TMM was ...

Yes, this is because of damage to the display. Either an internal crack, a separation of layers, or perhaps the frame was bent or cracked causing pressure on the display panel (same effect as when you press on the screen with your finger). Inspect the area closely for signs of physical damage. If the frame is bent and is metal, you could attempt to ...

the 6 components on the top are buttons... don't you have 6 buttons on your CRT? if so, it looks like he replaced the buttons' PCB.

I don't have this(PQ101WX01) screen personally ,but as far as I can Suggest is to make it more readable in sunlight you should increase the brightness of the screen and for sure your default OS will have this feature no matter its windows or Linux or any other.Dimming makes it less readable in sunlight because of the high intensity of sun due to which your ...

Assuming that you know what Adaptive syncing is about, Here is the difference between the two: Nvidia is looking to own the private market with the G-sync technology, where only their graphics cards paired with G-sync supported monitors can perform Adaptive Sync. whereas Amd plans to tread the open-source path, the technology that Amd is planning to use is ...

No. You can, however, set it to 1600x900. This means one “Windows pixel” will occupy exactly four (2×2) “real pixels” on your display. Unless, of course, some crappy scaling algorithm were to thwart this endeavor.

With what you describe, and the fact the problem is the same with two different cards, I would say it's either the monitor or the VGA cable. If you could find/borrow a different one of these, I would start with that.

The displays are described here: There was also a high quality DEC 340 CRT display unit with a round, ten-inch screen which could draw simple vector graphics, and an accompanying light pen could be used to draw on the display screen. As for why they were circular, I would expect that it was because that was the natural form factor for early cathode ...

Case A: There will be no graphics output. You can still connect a keyboard and mouse, but you won't be able to display anything Case B: You will be able to output video through your CPU, this is usually only good enough for excel/word/watching movies. Not recommended for gaming, rendering video, etc Case C: You will be able to output video through your ...

VGA is an analog standard and subject to distortions of this nature if there is a quality problem with the wiring or connector, or the cable is too long. If your laptop has a DVI, HDMI, or DisplayPort port, try connecting that (with the appropriate adapter if needed) to your TV's HDMI input.

Go to advanced system settings(Windows+pause, then click advanced system settings) then go to advanced tab, then performance settings. Enable use visual styles on windows and buttons(should be very last box).
