Computer as a gaming monitor?

Duffpro

I recently purchased a 27 inch iMac for my room. I have a smaller TV that I use my playstation with but only use the component red yellow white cables. I wanted to find something like dazzle, but with an hdmi port so I can ditch my small tv and get more out of my mac. (My 720p desktop doesn't get much use) I had found some of these converters online but my options are:
-get a very sketchy looking one that is like 10 bucks (kind of unrealistic)
or
-buy one that looks reliable for like 80-100 bucks.

Does anyone know anything reasonable? PLEASE PLEASE PLEASE HELP

Answer
Remember that your 27-inch iMac can ONLY receive a DISPLAYPORT video signal. It will NOT receive HDMI, not without a signal converter box.

You will NOT be able to use your 27-inch iMac as a monitor for a gaming console unless you buy a DVI-to-DisplayPort Signal Converter Box like the ones made by Gefen or Belkin, and those things cost like $150 apiece.

Simple $10 passive adapters will NEVER work. Don't even think it.

When playing games, my monitor looses signal?

Bobesko B

When I start to play a game, after like 10 or 20 minutes I loose monitor signal. I have Vista ultimate, quad core 9400, GF 9800 gtx+, 4 gigs of Ram. My monitor is Samsung t240HD. I have newest drivers installed from Nvidia web page and also my GPU is not overheating it has about 65 celsius while playing newest games.

Answer
This is sometimes caused by an inadequate power supply & a lack of Watts under load to the Graphics card...

Monitor loses signal during games???

HelpMe Ple

Hi, I have a really bad problem. When I play certain games, after a while the monitor goes black and says no signal. It has happened when I play TycoonCity New York, The Sims 2, and Worms 2. I meet the minimum requirements, and it has happened:

without an extra gig of RAM
with an extra gig of RAM
without a new monitor
and with a new monitor

Please help!!!

Answer
seems like you're having a problem with the graphics card installed on your pc or it needs an update. try to run a windows up on your pc and check to see if it has a drive update for your graphics. also download the latest Direct X through the microsoft website. this should help resolve any gaming issues.

while gaming monitor loses signal! help!!!?

Nuguns

During most games the screen loses signal and goes black and sound goes too. Have to do hard reset.

Screen of bfbc2 goes completely black or sometimes flashes black and white and have to alt tab and close it completely.

During play of heroes of newearth the sound suddenly makes a screech as the screen either flashes black or goes black. It will resume its self after about 30 seconds but either with lag or the colours have been screwed up.

Graphics card works perfectly so its not that
Power supply is far greater than my pc need so its not that
and ram has been tested and is working perfectly

Could be anything else.

PC specs

Processor: intel core duo E6700
Mother board: Asus P5L1394
Ram: two1gb ddr2 sticks
Graphics card: NVIDIA GeForce 8800GTX
Power supply: cooler master extreme power plus 700W

and i meet the requirements for the games i play

lots of people say its because i dont have enough ram but i dont see how that would cause it.
oh yes jeff L im using win 7

Answer
I'm going to take a shot at this, even though it is really stupid of me to answer without actually testing your system. Remember that I'm guessing, but my guesses are based on more than 30 years of experience in electronics, around 20 years of experience in designing and building computer hardware, and around 30 years of computer programming.

First, you definitely do not have enough RAM. The minimum for any modern version of Windows and gaming is 4G. The symptoms that you are describing are classic RAM problems. Remember that your computer has dozens of hidden programs running at the same time.

Second, if the error were due to corrupted video RAM or any other hardware or driver issue, the system would not recover, ever. It would always require a reset.

What is probably happening is that your system is running out of RAM, and is caching to the hard drive. When that happens, your sound and video will mess up temporarily, then return, but you will experience severe speed degradation, I mean severe lag, until you reboot. I'm assuming that you are running MS Windows, but regardless, once the OS begins to cache to the hard drive, it does not stop until you reboot. Some people think that hibernating or sleeping is the same as shutting down their computer; but they are not. You must do an actual reboot or shutdown to end the caching.

If your video is messed up, and does not return correctly, as you described for newearth, it probably means that the video modes have been switched, and video RAM is corrupted. This is common, and is usually due to poor programming by the game developers, or bad drivers from manufacturer. Sometimes it is due to hardware glitches but not often. It probably happens because you ran out of RAM and the game programmers did not allow for a "graceful exit" upon unexpected errors. It could also be caused by a virus checker or some other program trying to pop up a message box or something.

You might try playing the games in the lowest resolution possible, and see if you can play them longer. Also try to stop as many background programs and services as possible, especially any memory intensive ones, any programs that create popup message boxes, any programs that start and stop unexpectedly, and any programs that access the hard-drive during gameplay.

There is no way to know for sure without actual testing, but I hope this gives you some ideas to go on, and helps you understand why lots of people say its RAM. There is much more to say about this, I wish someone else could elaborate on this. Good luck!

How can i stop my computer from "blacking out" ?`?

gaming monitor no signal image

in_urma

Wenever I try to play a game my monitor stops receiving image from my computer,it turns intoa black screen and the little led turns off,my monitor only does this when it is not receiving a signal.
This only happens when i launch a game.The weird thing is I can't run my old games,like GTA witch I played for two years with no problem and now it doesbn't.I have my old video card GeForce 3 TI 128 mb I know it's old,but until now it worked perfect.I changed reinstaled my drrivers but it didn't help.It's not a resolution problem either,because I have set the max resolution and I still get the black screen.I know reinstaling my OS (win xp) would be a solution but I don't want that right now.
I havent made any changes to my PC's hardware or major software (drivers,OS,codecs) in about 6 months and it worked perfect until now.


Ideas anyone ?
It's not the game because every game I try I get thge same thing.Could it be a virus that afected my some video files in windows ?

Answer
It could be that your game file is corrupt, if you still have the game CD, try reinstalling it, if not then try System Restore as it will take you back to where you first install the software..

How many monitors can I connect to my laptop?

I have only one Monitor port on my Laptop, I want to connect 2 Is it possible ? If yes, how could i do ? My laptop is a Hp Pavillion Dv6.

Answer
You can connect 2 to you r monitor but, you would have to use a signal splitter. The problem with this is that you can only set one resolution for both monitors, so if one is a different size it will look distorted, and you can only clone the same image, so if you wanted the functionality of multiple displays that can display different things, you can't.

All is not lost if you want the functionality though. You can get a USB to DVI or USB to D-Sub adapter. There are fairly new, relatively cheap, and work great as long as you're not trying to game on it. Just search google or ebay and you'll fine tons of options. You can have as many unique displays as you do USB ports!

hope that helps

How are video games projected on screen?

gaming monitor no signal image

Lp182

I know that we aren't actually looking at a constant moving video game and that all we are seeing are multiple frames per second. But how is it done? I'm just curious how they do it. And are video games only projected at 30 frames and 60 frames per second, or are there other # of frames that can be shown in a given second?

Answer
The numbers 30 and 60 are a side effect of the NTSC format of television. Even back in the black-and-white days of TV, NTSC was a 640X480 image, interlaced (draws all the odd lines in one pass, then draws all the even lines on the next), and operating at 60 Hz. It wasn't until about 10 years ago that consumers started seeing any change to this, when EDTVs came on the scene and changed the interlaced to Progressive Scan (all lines are drawn sequentially on each pass), and then HDTVs changing the image resolution. Very recently, sets that can do 120 Hz have come onto the market. In Europe, they uses the PAL format, which ran at 50 Hz, but switched to 60 Hz for HDTV to simplify things for TV manufacturers (who had started to sell sets in Europe that could handle both 50 Hz and 60 Hz).

So for the longest time, TVs were displaying 60 half-frames (due to interlacing). As such, having a game run at 60 Hz would result in slightly smoother animation, but a lot more processing power which could otherwise be used to enhance the detail. So typically 60 frames games were smoother, but 30 frames games were much more detailed. Any other rate, and you the smoothness will vary, which is rather jarring to the immersiveness factor.

All of this only applies to consoles, though, since PCs have always had monitors that could do a variety of framerates, and therfore their games always strived for the highest framerate possible (and where 60 Hz is on the far low end) and don't really worry about the framerate dipping at times. High end modern monitors can typically do at least 140 Hz, and some older games on new hardware can actually create several hundred frames per second if certain settings are disabled.

Regardless of PC or console, the same programming technique is used for creating the frames and managing the process of sending them to the screen. Each object is placed in position in a virtual 3D space in RAM, textures are applied (only if they are facing the virtual camera's location), the view from the virtual camera is established, and the objects that the camera can see are flattened into a 2D image. This whole process is called rendering.

Then, the rendered image is put into a piece of memory (usually in the graphics chip itself) that has been designated as a "frame". This frame is then sent to the TV/monitor, and as it is being sent, a second image is being rendered and put into a second "frame". Once the first frame has been sent to the screen completely, the second frame is designated as the primary frame, and a third image is rendered and overwrites the first frame. This process is called Frame Buffering.

PCs (and maybe HDMI TV connections, I'm not sure) have the capability of the monitor being able to send a signal back to the game program and tell it when a frame is done being drawn. This allows the game to not switch frames while it is being sent to the screen (vertical synch), preventing a top section of an image and a bottom section of the same image displayed not matching up, refered to as "tearing". Since consoles know what frequency the TV is operating at based on the region (or more recently in Europe, through an option in the settings for either the game or the system), they can simply use an internal timer as an artificial vertical synch.

How do I make a video of a game without using my camcorder?

Cameron

I want to make videos of my game on YouTube. I've noticed that a lot of people make it look like you're watching the actual screen the game is on. How do I do that? Please help.

Answer
Use either a DVD Recorder or DVR, hooked to game machine, putting their signal out to the monitor or TV
