Unfortunately, you can't use your Android device as an external monitor in the way that you are describing. But if you have Remote Access enabled on your computer, you can remote into it using the Remote Desktop Protocol with your phone. There are a number of applications on the Play Store that can do this, I would suggest the Microsoft one though. They ...

Somehow unplugging and replugging the monitor cable from the DVI-D/VGA adapter with the computer running, then using auto adjust seems to have fixed everything. The adapter is a StarTech DVI2VGAE, I don't know if this solution is specific to the adapter or not.

There are a few answers indicating a digital signal vs. analog which is correct. But that does not answer the why? A few mentioned translation layers, this is sorta true too, a mainstream A/D conversion can cause a loss in fidelity, but you'd have to measure this as it is hard to see the differences with the naked eye. A cheap conversion and all bets are ...

HDMI and DVI are actually one and the same (at least in your context). DVI connectors are really just HDMI connectors with a different pinout (the rows of pins), plus VGA connectors with a different pinout (the pins arranged around a cross shape). If you look at your HDMI-to-DVI converter, you'll probably notice that the cross-shaped part is missing. So you ...

HDMI and DVI are very similar. Both are digital; the main differences are that HDMI supports audio and HDCP. When switching between HDMI and DVI, there is little actual conversion, but rather connecting the matching pins on the connectors. Display Port is a digital protocol, but VGA is analog, and the converter likely introduces small flaws and the reduction ...

Another issue is a lot of VGA cables are junk. If the VGA cable is less than 1/4" thick, you will probably notice ghosting on larger monitors (Higher the rez, more likely ghosting). I've even noticed ghosting on the attached VGA cable on some 19" CRT montitors. My VGA cables are about 1/3" thick and it really helps with the sharpness (Thicker wires, more ...

The others make some good points, but the main reason is an obvious clock and phase mismatch. The VGA is analog and is subject to interference and mismatch of the analog sending and receiving sides. Normally one would use a pattern like this: http://www.lagom.nl/lcd-test/clock_phase.php And adjust the clock and phase of the monitor to get the best match ...

Assuming brightness,contract and sharpness are the same in both cases, there could be 2 other reasons why text is sharper with DVI/HDMI: The first has already been stated, VGA is analog so will need to go through an analog to digital conversion inside the monitor, this will theoretically degrade image quality. Secondly, assuming you are using Windows there ...

VGA is the only analog signal from the above mentioned ones so it's already an explanation for difference. Using the adapter can further worsen your situation. some further reading: http://www.digitaltrends.com/computing/hdmi-vs-dvi-vs-displayport-vs-vga/

I use several Samsung capable 1920 x 1200, (WUXGA, (default resolution or “optimal”) monitors (Models 245BW, 2443 BWT, and a think a T240HD) all of which have a VGA , and a DVI connector. They are used in a multi-monitor workstation; using GeForce 9600GT boards (maximum capable digital display resolution is 2560 x 1600 (i.e., DVI); maximum (VGA is 2048 x ...

The D shaped female connector on your Dell PC is called DMS-59, or Dual Monitor Solution -59 pin. Although it is not a proprietary Dell solution, it is specifically designed to support two monitors from a single DMS-59 output on a half-height video card. A full height video card could fit two of these connectors, allowing connection of a total of four DVI ...

You need a “DisplayPort -> Dual Link DVI adapter”, like this: “Mini DisplayPort to Dual-Link DVI Adapter”

Have you considered just not going into standby? Personally, I disable standby because of performance issues and never wanting the disks to spin down. Could be a simple, permanent solution or a temporary one while you try to figure out why the monitor loses it's signal. Additionally, splicing in a 5v power transformer into the "hot wire" of the display ...

Based on your description you have those possible problems: Bad connection to Monitor. Check all cables are connected properly. Probability: low External monitor is not recognized as it's not set to DVI source. Turn it on and force DVI as source in monitor menu, if this is a model with both VGA/DVI input (most have auto detect, but this may not work well). ...

The problem is the HD6450 already came with a dedicated VGA port therefore you cannot convert the DVI to the second VGA monitor since the architecture of the PCB board will not allow to do so. You can either use VGA and HDMI or DVI and HDMI not VGA and DVI period. source

You didn't state the model of your laptop, or what graphics adapter it has, but earlier versions of HDMI (previous to HDMI 1.3) can't support anything above 1920x1200. Even if the graphics adapter supports higher, the HDMI port will limit it.
