Display sizes are determined primarily by how many displays will fit on one mother glass slab at the manufacturing plant. The manufacturing plant starts off with a single slab of glass, onto which the displays will be manufactured. Mother glass sizes are mostly standardized in the industry, and are increasing: Generation Size (mm) ...

I want my computer to power off my monitors (not standby mode) when I don't use it (no keyboard/mouse input) for more than 15 minutes, and power them back when such input is received. What you want is exactly what you are trying to avoid. If the monitor is actually, fully off, then it can’t turn back on from a signal on the video cable. To allow it to ...

The specific sizes that are in common use today are due to a mix of the following factors: 16:9 aspect ratio has completely taken over the market, due to movies and TV being produced in this aspect ratio, so the only way to display square pixels of 16:9 media (equal width-height ratio with no black bars) is to have 16:9 screens. This makes 4:3 and other ...

Let's look at the signals in a VGA connector: Pins 1, 2, 3: (R, G, B) 0 to 0.7V analog color signals to the monitor Pins 13, 14: (Hsync, Vsync) 0 to 5V TTL synchronization signals to the monitor Pin 9: 5V power to the monitor's I2C EEPROM Pins 12, 15: (SDA,SCL) 0 to 5V I2C clock and data to/from the monitor's EEPROM Pins 11, 12, 4, 15: (ID0,ID1,ID2,ID3) ...

[First Question] "Does a USB Monitor require a VGA Card?" In response to your first question, no a VGA card[1] is not required to display to a USB monitor. However, a USB card or port is required in order to display to a USB monitor. "This 16-inch portable LED monitor is a must-have laptop accessory and receives both power and signal via a single ...

Great Question. The answer is that typically the screen size advertised is the measured diagonal of the screen. This is the ratio of the length to width, and usually depends on the desired resolution. Consider the following calculation for a diagonal: This shows you can have a logically sized screen, but a weird advertised size. Now, this provides a ...

Does a portable USB monitor require a VGA Card? No. The USB monitor does not require any other video hardware resources. Some may take advantage of GPUs available, but they do not require them. If I buy a PC without any GPU capability (processor without integrated GPU + motherboard without D-Sub/DVI/HDMI ports and without any discrete graphics ...

There is no decent resolution that will look good on a digital connection other than the native resolution. The next step down that won't look like complete ass is 1:2 scaling at 840x525, but most games won't like a resolution that low.

The HDMI-CEC specification, which allows HDMI-connected devices to act as a limited remote control any other connected CEC-enabled device, defines the command System Standby which would allow the "remote" to switch the target into standby mode. This is the closest to what you have in mind that I know of. It requires that the target HDMI device (your ...

Yes, but you shouldn't. I think Synetech sums it up well, but if you must: Exactly how depends on the screen, but if it has an IR receiver you can connect an IR blaster to your PC to signal shut off (though as Synetech pointed out, if the IR is working, power is still being drawn). Alternatively you could use an Arduino or similar device to actually switch ...

The difference between the two monitors reside in pixel density. You have the same number of pixels in both screens but since the 27 inches monitor is bigger you'll have bigger pixels. The real question is the distance between you and the monitor. If you plan to use it on regular desktop then I would advise you to go for a 24 or 25 inches screen with a ...

The thing you're looking for is a KVM switch. Both computers are plugged into the switch, from there it's plugged into the monitor. You literally switch between the 2 PC's by a switch on the box.

You can get an HDMI KVM. This will let you plug one monitor/mouse/keyboard into two computers.

It has been my experience that the problem symptom you have seen is related to bad capacitors in the power supply board. I've replaced such capacitors in almost a dozen different monitors that had the same symptom and ended up working like new after repair. There have also been a couple of monitors where capacitor replacement did not fix the faulty behavior ...

Synergy would allow you to use one monitor on each and switch between machines. It synchronizes you clipboard between machines which is great and even allows you to drag and drop files between machines. Most people that I know with this issue use Synergy. I've also setup a single monitor KVM in the past and went dual monitor on one machine, and then used ...

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.

In short, no, you can’t. Not on a desktop. The power of the monitor is independent of any kind of communication from the CPU. It would be a nice feature, I’ll admit.

My info did not show up in XOrg.log. But I figured out that I could get the info from the DRM (Direct Rendering Manager) subcomponent of the linux kernel, which is exposed in sysfs. So I did the following: root@dark:~# ls /sys/class/drm/ card0 card0-DP-2 card0-eDP-1 card0-HDMI-A-2 card0-VGA-1 version card0-DP-1 card0-DP-3 card0-HDMI-A-1 ...

In Firefox you can access it through Tools → Web Developer → Responsive Design View You can choose a pre defined screen size, or input your own.

No, its an ethernet port - presumably off an ultrabook (Maybe a Zenbook?). Its however got a little extendable bit so its slimmer. You can't plug a monitor into it. You seem to have it confused with a displayport or maybe even a mini display port (both from displayport/wikipedia) or maybe even HDMI - which amusingly is sometimes used for switch to ...

There are a range of interfaces used - some semi standard and some proprietary. This page, dated February 2010, so almost 4 years old, How do I connect my VGA card to a LCD display taken from an old laptop ? provides some useful information. He identifies the following typical interfaces: Analog VGA (used in external LCD displays but not in laptops ...

The VGA port on a laptop is output only, it cannot be used as an input. You'll need to connect a device with VGA input like a monitor or TV if you want to use an external display.

Analysis After doing a quick search, there are some other people with the same issue, most of which didn't solve it. I also found a blog post explaining how to solve the problem in Windows 2000, which basically involved doing the steps you probably did back when using Windows XP, albeit without success in Windows 7. Monitor I couldn't find much ...

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, 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 ...

Last bad (valuable) LCD monitor I had- one of the 30" Samsung monitors on my CAD workstation- was a BGA solder joint that went bad. Irritating when they don't match cosmetically and in terms of control placement. Yours does sound like it could be the power supply. Maybe look at the startup resistor as well. I think these repair questions are considered by ...

This does sound like a bad caps on the inverter section of the power board. Dell has used subtandard caps for the last decade. Prone to capacitor plague. But 90% of the time the caps are physically blown or leaking. Even without the physical signs, that it turns on for a few seconds screams bad caps. You can buy a new power board (or swap one from the other ...
