2 displays cuts video ram in half?

i was told by a guy today that if I use two monitors with my tower, that it cuts the video ram in half, sounds logical...if this is true, why would someone want to use two monitors instead of just buying one big one?

Actually it's not true. VRAM is used for more than one thing and displaying video to the display is only one of it's uses. You might like to note that the largest display, a 30" display, only requires that 128MB VRAM be present.
The reason one would opt for using two monitors is that with two displays you tend to use a different workflow and window placement than you would with one display. Not to mention that those who use two display generally have at least one of the displays being at the "larger" size anyway. Some do it because they already have two displays at their disposal without having to buy anything extra. Some do it for video previewing where LCDs aren't recommended for colour matching.
There are many reason why two display would be used beyond the obvious pixel count.

I installed Windows 7 on my early 2011 stock Macbook pro 13" and it cut my RAM in half it syas i only have 2GB when i have 4GB. The version of windows is 7 Ultimate 32 bit

More details-
i Burned the ISO to a DVD and installed it like that, then after the installation i installed all the latest drivers that i downloaded before the HDD partition. the windows partion is 50 GB which seems subsantial as i will only be using it for school programs that arent for mac. (this is off topic but some how without installing anything i have only 20GB of the windows partion left. dont know how this happend). this is all on my early 2011 Macbook pro 13" everything in it is stock, it came shipped with 4gb of RAM and a great Intel I5 dual core 2.3 GHZ with the Intell HD 3000 348MB video.

Hi
32-bit Windows has an address space of 4GB. Part of that is used by system BIOSes and graphics memory. With my Mac Book which has a 1Gb graphics card you only get about 2.6-2.8GB of the RAM which would be addressable and usable.

Windows 7 64 bit cuts video ram in two

Well, i just bought the new Imac 21.5 I configured it with and 2.8 i7 prosessor, and 8 gb ram. It came with a 6770 512 mb video card. I am very satisfied with the imac
but i installed windwos 7 64bit trough bootcamp, and if i type in dxdiag in the serch box it only says that the videocard is 229 mb of vram. And its confusing
since the only reason i bought THIS imac was so i could play game at a fair level of graphics. Any ideas people? I do have the newest driver and so forth.
But those are the drivers that apple provided with a link, i do not have any other driver directly from amd if that matters...
Cheers from cold Norway.....

The trouble is usually installing though the last 11.10 beta seemed to be less trouble and possible.

As for the amount of vram, I have 1GB on mine but the output shows 3825MB (the way vram and system memory are used). Also have 8GB RAM.

G4 Quicksilver - Enough Video RAM to drive 20" Apple Display?

I have one of these with 64Mb Video Ram, but will it drive an Apple 20" Display? ... at what resolution?

Will ATI 5770 help me display HD video without stuttering?

I have a 1,1 Mac Pro with the stock GeForce 7300 card which powers an Apple Cinema HD display via an ADC adapter and a no-name 1280x1024 DVI monitor. Works well but my system struggles with 1080p video. I edit with Final Cut Express and frequently the video will stutter when I play it within FCE or Quicktime.
Running latest OS and the system has 5GB ram and a couple of 7200rpm discs for storing video footage.
If I upgrade to the ATI 5770 will that display HD video more smoothly, or is it the speed of the CPU in my Mac Pro which is holding me back?
Grateful for any advice you can offer.

I'd try at minimum 10 to 14 gigs of ram.

Audio doesn't match video because repeated half way through

Hi guys,
I am currently editing videos from my Canon SLR with Adobe Premiere Elements (Windows).
In the same project, I have only uploaded videos taken the same day with the same equipment. I have been able to process them all normally apart from one. For some reason, when I play this file with a basic video player, everything works fine but when I import it in the Adobe software and play it either through the small window or in the timeline, I have the same problem:
Everything works fine (audio and video in sync), until it reaches a specific point (totally random as far as I can tell) when the video keeps going but suddenly the sound repeats itself from the beginning of the file (and the audio which would correspond to the video is replaced by it). For you to understand better the problem:
Video:   ABCDEF
Audio:   ABCABC
I have tried opening it in a different project and somehow it happens exactly at the same point.
I am totally clueless of what it comes from and getting really frustrated!
Any idea?
Cheers
Babs

Hello, I'm new to using forums like this. Is it appropriate for me to post that I'm having the same issue? Also sounds similar to Audio doesn't match video because repeated half way through as well.
My situation is:
Win7 64-bit, i7 920, 2.67GHz, 8GB RAM
Multiple Nikon D7000 video clips I've taken play back fine except for the following clip. In Windows Media Viewer, I have no problem, but in PE10, in the timeline editor, this clip repeats the audio from the beginning starting about 6 minutes into the video. I have Quicktime version 7.7.5 installed which I noticed was mentioned as a possible culprit in the other thread.
I've been using my camera primarily for stills, but decided to have my mom tell her story before she wasn't able to. I'm so frustrated with this problem because I know the audio is just fine since I can play it back synchronized throughout the entire clip in WMV. I've tried cleaning out PE caches as best I can figure them out and created new projects without any better luck.
Any help would be greatly appreciated. I'm open to getting a new version of PE or another program if I could believe that I wouldn't run into this issue again. This seems like such a vanilla problem since all my other clips seem to be fine and this one does too on WMV.
Thanks for any help you can provide. I don't really know where else to go to figure this out.

Video RAM fails in Tech Tool Deluxe....

Hello again,
I reformatted my harddrive a couple days ago, and the computer is getting quicker but I KNOW it could be faster so I did a Full Diagnostics using tech tool deluxe. The first time I did it, it passed on everything. Then the next time I was browsing the Internet, I get a Kernel Panic out of the blue. I downloaded the "menu Meters" program and None of my computers resources were Anywhere from intense (1-3% tops CPU usage) So I reboot and do the Tech Tool test yet again and This time my Video ram Fails the Diagnostics. It tells me that I should Close all Applications, Check any recent hardware installs, Reinstall the OS , then call Apple care, in that order. I tested it again after unplugging my 17" LCD from my macbook pro and I passed the Test?!
I am going to call Applecare tommorow afternoon, but do you think they will fix/replace my macbook pro if it is now passing the tests? Before I install Final Cut Studio I want to make sure I don't have to worry about any other problems with my computer. Especially something as vital as V-Ram. Plus according to my friend at a techshop, the video ram supposedly has a bad sector which was randomly diagnosted during the Techtool session, because I was using a second display, and that my Video Ram will gradually get worse and worse until I will have to send it to apple either way.
I'm interested in any information you would like to post on the subject. I am going to get it fixed one way or the other, but it's nice to have some extra input on my side when I call Applecare (it will be my first time actually).
If anyone has any tips, or comments they would be appreciated,
Thanks.

When you did a clean install of your MBP did you write zeros to the hard drive. While it probably has nothing to do with your VRAM failing its tests it is good idea to do it anyway.
As for your VRAM failing, I would reset PRAM and NVRAM…
http://docs.info.apple.com/article.html?artnum=2238
… and the System Management Controller…
http://docs.info.apple.com/article.html?artnum=303319
… imediately prior to clean installing (and writing zeros to the drive) a second time.

128 MB video ram on a macbook pro - enough to drive the new 30"?

128 MB video ram on a macbook pro - enough to drive the new 30"?
meaning, can it do this well???

Even 16 MB VRAM would be enough to display a 2D picture on the 30".
Depending on 3D usage you need much VRAM.
Unless you are using a lot of the latest 3D games or Apples 3D pro apps (Motion/Shake or something like that) 128 MB should be fine.

Satellite 320 CDT video ram problem

Hello
I have an old Satellite 320 CDT laptop with a display problem.
It works ok but display is abnormal. It does special effects (moving zebra style, especially in 32 bits display mode).
The same problems happens with an external monitor.
I am looking for replacing the video ram IC because i'm nearly sure it is the problem.
First step i need to open the laptop. I've removed the battery pack, the hard disk and all the screws but i can't open it.
What is the correct method to do this ?
Second step, how to locate the video ram component ?

Hi Pascal
To be honest I think there is no sense in doing that.
The point is that your issue could be related to the faulty graphic card and the graphic card chip is fixed on the motherboard. Mostly its not possible to remove this chip and therefore the whole motherboard must be replaced.
I think its better to search a little bit for the similar notebook on eBay.
A second hand notebook would be much cheaper as a new motherboard for the Satellite 320CDT
Regards

TechTools Deluxe (Re: Video RAM and reinstall)

I have the annoying screen inverter/logic board whine (yes I know this has been talked to death here), sometimes not so bad and sometimes I can hear it over a desktop PC is the bearing going out in one of the fans. I happen to be visiting family in a city with an Apple Store this weekend, so I thought I would talk to a real person face to face. Anyways, I ran the TechTools Deluxe CD that I received a week of so after I got my MacBook Pro. To see if there was anything else besides, my whine to mention to them and will you look what came up
Video RAM
Failed
Video RAM, as all components of your video circuitry, must be fully functional for graphics to be properly displayed. Damaged VRAM can cause missing bits, screen noise, system lock ups, or freezes. TechTool Deluxe tests the VRAM on the Macintosh main logic board, as well as some third-party video cards.
If the VRAM test should fail, try these steps in order and run the test again after each step:
o Quit all other applications.
o Restart the system.
o Check any recently-added hardware for proper installation.
o Run the computer from another volume (if available).
o Reinstall the OS.
o Contact AppleCare.
I have done everything except reinstall the OS and contact AppleCare.
Anyways I wanted to know first of all if anyone else had gotten this error and if so did a reinstall fix it? Secondly how hard is the reinstall, I come from years and years of DOS, 3.1, 95, 98, Me, and XP, and one thing all of them have tought me, is reinstalls are horrible, drivers don't work again, ect. So is OSX easy or should I just ask them to look at it this weekend?
Oh and the Apple Diagnostic on the OSX cd 1 says everything is fine.

Well the apple test (on disk 1 of OSX) states that nothing is wrong. Though I will test again when the temp gets high since some people had been detecting problems.
as for 10.4.6 I downloaded it the other day.
I repaired the permissions had a couple things that it corrected (I don't know if I posting them would do any good) Out of curiousity how to permissions get incorrect? I'm so used to the windows file structure and DOS before that that i am a little confused. The last apple used alot before this macbook was an old Applee IIE.
and the TechTools still says there is an error, every time I have run the test. Though there have been some differences when I reboot or turn of and wait a second and then restart.

Missing video ram

I have a 1ghz Titanium G4 with the ATI 9000 mobility 64mb video ram. OSx 10.3.9 1gig ram
Recently I have discovered that the system profiler lists my total video ram as 32 mb. My overall game performance seems diminished when playing graphically intense games such as Unreal Tournament 2004.
This discovery seems to have occurred around the same time that I had a battery charging problem which I have since fixed. My system has also been suffering increasing freezes upon wake from sleep or screen saver.
I recently perfomed an archive/installation of my OS hoping that might restore some corrupted files in the system, but no luck.
Has anyone else seen this problem or know of a cause/solution?
Thanks.

Hi, pioche. A 1GHz Tibook certainly ought to have 64MB of VRAM, and if it doesn't, the only reasonable conclusion is that the missing half has failed. It's all soldered onto the main logic board, so the remedy is to replace the board. Of course another alternative might be to avoid asking too much of the remaining 32MB, and thereby save quite a bit of money. That's what I'd do if there weren't any other signs that might point to a larger failure of the LB, but it sounds as though yours may be on its way out. Have you run the Hardware Test CD that came with the Powerbook?

Descktop J4550 Some font lines are cut off at top half of row

The subject line above says it all. Just need to know how to correct the problem. Descktop J4550 Some font lines are cut off at top half of row

My personal opinion is that it is a problem from some books that have been published via Smashwords. That has been my experience for one or two books I've downloaded. I contacted the author in one case and he replied:
"Just to let you know I've had some feedback from Smashwords about the odd display issue. It's relates to the line spacing in the original document, apparently. I'll be uploading a fixed version to them in the near future, though it might take a while for the new version to trickle down to the iBookstore."
So I dunno if your book is published by Smashwords, but if it is it may be worth contacting author?

Error message AHT 1.2.3: Error code disp/13/2 in video ram test section

Hello to the forum,
i have garbage on the screen on my Titanium DVI 867MHZ, so i run AHT in extended session and on video test section the first test with green-red stripes on screen runs but then the message Error code disp/13/2 appears. Does that mean the display has a problem or the video-ram is faulty or the grafic chip?
Greetings iMacG5-User

Unfortunately, AHT's very cryptic messages are intended to benefit Apple technicians, not ordinary civilians. That said, any message about a video or display problem is bad news, because it probably means replacing either the logic board or the display, and each is very expensive.

AHT Video Ram Error

I have been having a string of kernel panics and AHT v1.2 detected a video RAM error "disp/13/2". In a previous post, it was suggested that this message meant that many things were fried and that a new computer was the best option. Has anyone successfully repared this problem, and how do you do it?

Tecra M10-1H4 - Changing shared video RAM value?

Hi there,
I have a Tecra M10, with the standard 2GB of RAM, I also added an extra 256mb in the available RAM slot. Can I change the shared Graphics RAM value? In the properties of XP Pro I can see it is set at 1024MB which is silly since I only have 2.25GB in the machine.
I can't seem to locate any settings even in the BIOS, where I thought I could change this. It is a mobile Intel GMA 4500MHD graphics chip. Any help is appreciated...
I also seem to get some horrible slow downs on the laptop too, when I have about 10 different windows open, (be it the same app or different ones) when I switch to a different window/app on occasion I have to wait for the laptop to redraw the new window very slowly?
I've updated the driver too - claims i'm on: 6.14.10.4953
Cheers
TC

Hi buddy,
No, you cant change the value of video memory. Everything will be controlled automatically and there is no value in BIOS or display driver where you can change this.
Video RAM depends on RAM you use on your notebook. Increasing system memory the values for total available graphic memory, decided video memory and shared system memory will be higher and higher.
So, to get more video RAM upgrade your notebook with more system RAM.
