display interview questions
Top display frequently asked interview questions
I'm usually connecting my laptop to a larger screen. I'm away from my desk for a few days and I'd like to know what model of monitor that is. I just remember the manufacturer, size and and native resolution. I know that Windows remembers previously connected monitors and their settings. Does it also remember more details about them, like monitor model?
Can I view a list of monitors that were connected to a computer in the past? I'm using Windows 10.
Is there a way to turn off the display in Windows (7), preferably without using additional software?
Powershell script works fine, but leaves command-line window after turning on the display.
Equaling 3 Displays Total (or 2, if the laptop display cannot be used).
I work at home on two large monitors, but at the office on a laptop with a single large monitor. Is it possible to attach two (or more?) external monitors to a laptop without having them clone each-others display?
I've noticed that recently many websites are slow to display their text. Usually, the background, images and so on are going to be loaded, but no text. After some time the text starts appearing here and there (not always all of it at the same time).
It basically works the opposite as it used to, when the text was displayed first, then the images and the rest was loading afterwards. What new technology is creating this issue? Any idea?
Note that I'm on a slow connection, which probably accentuates the problem.
See below for an example - everything's loaded but it takes a few more seconds before the text is finally displayed:
I usually just use Fn + Left or Fn + Right to adjust my screen's brightness but the minimum settings are still too bright for me (especially when I'm working at night). I tried going through the Power Options in the Control Panel (plan brightness already at the lowest settings). Is there a way to dim my laptop's screen beyond the minimum?
I'm already using Fl.ux. I was wondering if there was a utility similar to it that adjusts my screen's brightness/contrast instead of its color temperature.
I have loads of grubby finger marks on my monitor (mine and smaller people's). I'm not sure how to clean them off without damaging the monitor.
What's the best way to safely clean dust, smudges and fingerprints off an LCD?
I love the Chrome browser, but I use XML quite a lot in my development work and when I view it in Chrome I just get the rendered text.
I know that the source view is slightly better, but I'd really like to see the layout and functionality that Internet Explorer adds to XML, namely:
- Open/close nodes
Any ideas how I can get this on Chrome?
The XMLTree Extension is available on Google Chrome Extension Beta Site.
I just bought a 1080p 22" Samsung Syncmaster 2333HD (connected via HDMI) and the picture and video quality is great but the text quality is absolutely horrible. This monitor has a built in HD TV tuner.
Even as I type now all the text in this text box as well as in the browser toolbar and start menu, etc looks weird - like it all has a white outline around it that makes it jagged and hard to read. It hurts my eyes just to look at it.
I am running my PC in the suggested native resolution of 1920x1080, so what's the problem?
Is this one of the unavoidable downsides of using a HD monitor? Is there a solution to the problem?
I need a way to generate reports or logs that prove that my Internet connection is flaky. My Comcast connection is very flaky but if I ask their support to send someone over it will probably work fine while the guy is here.
I found and tried "Connection Monitor" from CSGWare Corp but it does not create the kind of reports or graphs I'd need to be able to convince my ISP that their link is intermittent.
What I need to be able to do is have the software monitor my connection and produce a record of when the connection dies or when, for example, ping time climbs dramatically.
Can I get Connection Monitor to do this or is there another program that does?
I have a 3 monitor setup (each 1680x1050) via an Nvidia NVS440 (2 GPUs, 2 outputs per GPU totalling 4 outputs); this works fine under Windows XP,7 but caused considerable headaches under Linux (Ubuntu 9.04).
I had previously used an XFX 9600GT and the onboard XFX 9300GS to produce the same result but the card was noisy and power hungry and I was hoping that there was some magical switch in the NVS4400 that got rid of this annoying problem - turns out the NVS440 is just 2 cards on one physical PCB :-p (I searched the net high and low for people using this card under Linux but found nothing, if anything the card uses less power and is fan less so I was to benefit from it either way)
Anyway, using either set up there were 5 solutions available:
- Have 3 separate X instances, all un joined
- Have 3 separate X instances, adjoined by Xinerama
- Have 2 separate X instances - One using twin-view, both adjoined by Xinerama
- Have 2 separate X instances - One using twin-view but no Xinerama
- Have a single Twin-view setup and leave the 3rd screen unplugged :-p
The 4rd option, using 2 separate X instances and twinview (but no xinerama) was the best balance in terms of performance and usability but caused 2 really annoying issues
- You couldn't control (without altering the shortcuts) which screen an application opened onto - and once it was opened you couldn't move it to another screen without opening up terminal and forcing it to move
- Nvidia's overriding or falsifying of Xinerama breaks and the 2 screens joined by Twin view behave like a single huge screen causing popups to open in the middle of both screens and maximising of windows stretches to the width of the first 2 screens
- Firefox can only run one instance as the same user so having multiple firefox windows requires at least 2 users
The second option "feels" like the right option, but OpenGL is basically disabled and playing any sort of game or even running anything graphical causes a huge performance drop and instability - even trying to run a basic emulator for gba or gens just causes the system to fall over. It works just enough to stare at your desktop and do nothing but as soon as you start doing some work - opening windows, dragging things around - running multiple copies of firefox it just really feels slow.
The last open, only going dual screen works perfectly and everything performs as required, full GPU acceleration - two logical screen spaces - perfect, just make it work across GPUs like windows! :-p
Anyway, I know RandR was supposed to pick up the slack when it would introduced GPU objects of sorts to allow multiple GPUs to be stitched together to create one huge desktop at a much deeper layer than Xinerama. I was wondering if this has now been fixed (I noticed X server 1.7 is out) and whether anyone has got it running successfully?
Again, my requirements are:
- One huge desktop to drag any window across
- Maximising of windows to each screen (as XP does)
- Running fullscreen apps on the primary screen and disabling the mouse from moving onto the others or on all 3 stretched
Finally as a side note; I am aware of the Matrox triple (and dual) head splitter but even the price they go for on eBay is more than I can afford atm, my argument: I shouldn't have to buy extra hardware to get something to work on Linux when it's something that's existed in the windows world for a long time (can you tell I don't get on with X :-p); If I had the cash I'd have bought the latest version of this box already (the new version finally supports large resolutions as the displays I have 1680x1050 each).
I was wondering if it was possible to power on/off a display using a computer connected via HDMI. Let me explain :
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. My monitors are connected over HDMI, so I was wondering if it was possible to use the CEC functionality with a computer.
If is it possible, then is there a hardware requirement ?
My point is that I often take a break from my computer, but forget to turn off the screens, and I would prefer to shut down the screens completely instead of putting them to standy mode
Thanks a lot
To support 10-bit color the following are needed:
- A monitor supporting it.
- A GPU supporting it (only AMD FirePro and NVIDIA Quadro support this?).
- Compatible software. Unless I am mistaken there are very few programs out there supporting 10-bit color. Photoshop is a notable example.
The questions are about how 10-bit monitors perform in comparison with 8-bit monitors:
- In which situations would a 10-bit monitor give a noticeable advantage over an 8-bit monitor (say, for professional photography)?
- Have 10-bit monitors been compared against 8-bit monitors based on subjective or objective tests? What were the results?
- Human eyes can see only 10m colors, so would using a monitor with 1b colors make a difference?
I need suggestions.
I've got a live little bug inside my macbook pro screen for 2 days now.
I've tried to film it using my iPhone, but it ain't that good. :(
Should I try to open it? o_O
C'mon, looking for ideas here! :)
edit: Here's an alike video.
It's not moving anymore for now... I hope it isn't dead! Right when I've found a possible solution along with many ideas on that link: suction cup; monitor off and lamp on to attract it out; scratching the screen (made it move a little); and got to know there's no warranty for this "feature" (also known as bad design in a jargon).
edit2: It's been "fixed" on its own. Just check the answer.
I have 2 monitors connected to a NVIDIA GeForce GTX 660:
- Left is 1920x1080 via DVI (Samsung SyncMaster 2443BW)
- Right is 2560x1440 via DisplayPort and is set to Primary (Samsung SyncMaster SA850)
I often leave my computer running overnight (working on long render job, doing backups, etc) so I only power off my monitors manually. However, if I power off the primary monitor, it is disabled completely as if it were unplugged from the graphics card (i.e. icons are moved, open apps are moved and resized to fit on the new primary monitor). If I switch from DP to a DVI cable, this does not occur. It seems to be an issue when using DisplayPort.
Is there a way to disable the monitor from being disabled completely in Windows when I power it off physically?
I have found no relevant settings in either Windows Display settings, nor the NVIDIA control panel software.
Edit #1: I'm using an Oehlbach Transdata DP 510 cable.
Edit #2: Here is a screenshot of my NVIDIA Control Panel v7.2.710.0:
Edit #3: Here are screenshots of my Monitor configuration:
Clicking on Advanced settings reveals a Generic PnP monitor running at 59 Hz? 60 Hz is the only other option available.
Here is my secondary monitor which is connected via DVI:
Edit #4: If I open the "Screen Resolution" configuration panel and power the monitor off (via the power switch), this is what is shown:
It looks like I disconnected the monitor from the video card.
