Display Issues, Mac Mini and Sony LCD TV

Hi,
First my setup:
Mac Mini(Core2Duo) = DVI2HDMI = Pioneer ASX2 = Sony Bravia 40W2000
I have two issues, in order of importance:
Issue #1: When switching off the Pioneer my Mac Mini will suspend. This is not wanted, because I somethimes want it to either work on the iTunes library (hours of work) or download torrents.
Issue #2: The famous my display is not 1080p anymore but VGA. Has anyone fixed this?
I haven´t seen any fixes to issue #2 even though it´s super common. I do hope that anyone can sort me out on issue #1

Both items #1 and #2 can be corrected using the Gefen DVI Detective.

  • Mac mini and Sony tv resolution issue

    Hello,
    I have recently purchased a Mac mini for the purposes of hooking it up to my 51" Sony Wega HDTV. I took the mini out and connected the DVI adaptor that came in box and then hooked the mini to the tv via HDMI cable thinking this was the best possible connection for my mini. I have an issue where the screen is over flowing off the TV screen. I looked in system preference and have very limited resolution options but 1080i was selected and also over scan was checked. If I deselect overscan I get borders which I don't want. My tv doesn't have many options so how can I calibrate these two to work togethor?

    I just discovered this is not a TV issue at all...
    Uh, yes it is. Overscan is a condition unique to TVs. Computer monitors don't do it (overscan) hence there is normally no need for the kind of graphics card driver you are talking about, e.g. one that has precise control of video borders.
    Many TVs on the market today have a method for defeating overscan, tucked away somewhere in their menu system, in order to allow the TV to be used just like a computer monitor. That is always the preferred solution when it is available because it will make the best possible image on the TV.
    Your TV is a rear projection TV. Such TVs are not well suited for use as computer monitors because overscan is naturally baked into the optics architecture, meaning the manufacturer deliberately sets the mirror and lens system in such a way as to cause the native resolution (1280 x 720 in the case of your TV) to extend beyond the edges of the projection screen. Therefore it is impossible to get the native resolution of the projector's engine to display fully and perfectly on the screen. Only scaled or bordered version of it can ever be displayed. It's all fixed at the factory and there's no getting around the fact.
    For the original G4 Mac mini that had ATI Graphics, there was a driver like the one you found for your father's Windows computer that allowed video borders to be set independent of resolution. But apart from that early effort on the part of ATI, I have not seen anything like that since for minis that have graphics based on Intel or nVidia hardware. I think you are going to be stuck with the dark video borders as a necessary limitation of the TV you own in the absence of any driver to counteract that limitation.
    I believe the media center front end app called Plex has a facility for setting video borders, but I've never used it personally since I am able to turn overscan off on my TV. So I can't vouch for how well it works. And in any case, since it is bound to the app, it will only be active when Plex is running and not when, say for example, the Finder is in use, which is when you most need it.

  • Intel Mac Mini and Sony Wega displays

    I purchased one of the G4 based Minis for use in my media center. At that time I had quite a bit of difficulty getting it to work with my Sony KDF-60xs955 60" HDTV. I did eventually get it working and stable but the process, when written down for others in this forum post, is somewhat intimidating.
    My parents really need a new machine for their daily use and I'm going to be donating that Mini to them. Before I replace it with a new intel Mini (yay Front Row!) I want to know whether it will autodetect my television or not. I have no desire to spend the 4-5 hours needed to hack it into working again, plus the hassle of getting it to work again any time I switch displays for a few hours. More importantly I don't feel like I should have to...The HDTV is automatically detected by a PowerBook and that works flawlessly.
    One of the major reasons I pay higher prices to Apple is so that it just works. My new iMac? It just works. My old PowerBook? It just works. My old Mac Mini? Not so much... So, here I am hoping to get an answer out of these forums: To buy or not to buy that is the question, whether tis nobler to suffer the slings and arrows of outrageous non-support or to take my cash away from this sea of troubles and by opposing end them.
    Thanks.

    Hi there,
    I have downloaded the lastest Windows Media Player from Microsoft for Mac OS X, but it doesn't officially support the Intel Macs. It runs with wmv videos from my harddisk, for example, but I also can't play the amazon.com sound samples (I just tried). I guess it's because the Windows Media Player is running via Rosetta, maybe there is some problem there.
    For the moment I could only suggest to use the Real-player sound samples as a work-around. Real player does work on the Intel Mac with these sound samples. Just that on my machine it does only download and I have to start it from the desktop instead of right inside of Safari. Maybe it's just a question of preferences, but it does work, at least.

  • MAC Mini and Sony TV LCD  question

    In the past, when I connected to my Sony projector tv, unable to use the highest setting because lost part of the desktop with icons on bottom and entire top bar. New Sony LCD used and same thing happening. I am using a HDMI connection on the Apple. Wonder if this would happen if I switched to analog? Any other settings I can manually adjust to get the full screen and menu bars??

  • Mac mini and sony 46X2000

    I have a mac mini, os 10.4.11 connected to my SONY46X2000 via VGA cable. It works perfectly most of the time, screen res is set to 1024x1280 and the display is recognised as a sonyTV. I am however experiencing the odd drop out, where the screen goes completely blank. It returns after a few seconds. Could this be overheating? are there any such known issues, it does appear to occur when the mini has been left on for a long period (days, rather than hours).

    Yes, that adapter would do it. There are also full length cables with DVI at one end and HDMI at the other. FutureShop seems to sell those as well.

    But before you spend money on this solution, it would be good to confirm a computer connection is supported by the Sony over HDMI. Check the Sony's user manual to see what it has to say about making computer connections.

  • Share cinema display between Mac Mini and MacBook Pro

    Hello -
    I am keen to get an LED cinema display to use on my new MacBook Pro - but I share my study with my children - so want to give them a MacMini to use.
    How easy is it two swap between the MacMini and the MacBook Pro ? I guess there is only one input in the LED cinema display ???
    Thanks in advance.
    Andrew

    Interesting - I have the same idea: sharing a 24" cinema display between a Macbook Pro for myself and a Mac mini for my wife.
    The only problem I see is that the display doesn't have any Firewire ports. So if I want to use an external harddrive (or a mini-DV camcorder) on both computers when connected to the display, then I'd have to plug that into the computer instead of the display ...

  • Mac mini and lcd tv displays

    I currently have a g3 ibook and a g4 imac. I've been debating on what i should buy as an upgrade. I've been torn between virtually all macs including the powerbook, ibooks, imac, and the mac mini. I'm moving in a couple of months to a temporary residence where space will be limited. I just purchased a very nice philips 37 inch lcd display with vga inputs and hdmi inputs. After much thought this is what i think i'm going to do.
    Sell the G4 imac or give to my parents. Keep the G3 ibook but install the max ram for it (is 512mb the max for this old cpu) and replace the old airport card with a new airport extreme card. Buy an extreme base station. Get a mac mini w/ wireless mouse and keyboard and run it through the philips. Any thoughts?
    If i go this route i keep the ibook for portability and the mac mini gives me a more powerful at home cpu. This would keep costs down and not take up as much space. Anyone have their mini hooked up to their lcd tv?

    Hi Martin,
    I appreciate your thoughts : I have a G3e key Lime Clamshell 466MHz iBook, I put a 256MB SIMM in to take the iBook up to 384mb and it's now OK for Tiger - I used the Apple Video Out cable to a sony CRT TV via SCART and was able to struggle thru Bridget Jones 2 on DVD , but got a headache! Wife was UNHAPPY. suggestion is avoid!!!!!!!!!!!!!!
    (maybe sell your iBook at a premium on an online auction website?)
    I'm pretty sure that Airport Extreme cards - being a different size and shape from the old ones won't allow you to upgrade that way. I did buy an Airport Extreme enabled Mac Mini 1.25GHz 40GB 1GB RAM for driving my Dell 26" LCD TV/Monitor. It is F A N T A S T I C ! The Dell W2600 came with DVI to DVI cable which plugged straight into the Mini's DVI with no adaptors. The Dell was recognised and a profile was loaded by 10.3
    Most important point :-
    I adjusted the Mac Mini screen output resolution to EXACTLY the Dell W2600 Native Resolution of 1280 x 768 (WXGA) (720p HDTV).
    with a mismatched native resolution the modern TV's like your Philips 37" will start to resample and might make artefacts (mine did!)
    The Mini's 32MB video RAM will not drive much higher screen resolutions than 720p anyway!
    Well, after some playing , and loading of helper programs like VLC and MTR , then you'll find that Mac Mini to big LCD is the best ever quality that you've seen your DVD's played. When you download the Apple QT7 H.264 HDTV 720p trailers, you'll have seen the best ever TV quality imaginable!!!!
    for extended use as a desktop PC, the Mac Mini would be better firing into a 17-19" LCD,
    the 26-42" displays are so big that you have to stand 6+ feet away from them at least !!
    I used a BT dongle (I had it lying around) and the Apple BT keybd and mouse work well, in fact, I can type from the other end of the garden - just I can't see what I'm typing!
    I bought my 3rd & last Mac Mini tonight for Euro 399 (£264!!!) as the blowout of the Rev.A 1.25GHz 40GB 256RAM 32 VRAM models. My main Mini really uses its 1GB ramstick when encoding MPG4 via the EyeTV200, but the sub £300 price makes the Mini phenomenal, unbeatable and so versatile!
    I'm sure you'd be happy with the Rev.B with the BTO options until Rev.C comes out!
    what's the native resolution of your Philips LCD? is it video protected path?

  • Mac Mini and thunderbolt/vga to LCD TV

    Hi All,
    Here is an interesting one......
    I have just taken delivery of 5 new Mac Minis which have the thunderbolt port on them.  The Mac Minis each connect using displayport tb/vga adapter to a switch then on to 5 LCD TVs.
    The HDMI/DVI is not used.
    In this config, if I start a Mac Mini the display will not route through the Thunderbolt/vga adapter to any of the TVs (even though I have selected them on the switch). The display seems to want to go through the default HDMI port.
    If I connect a standard PC monitor to the tb/vga adapter and reboot, the screen shows correctly on the monitor.  If I then change cables without a reboot, the LCD TVs show correctly!
    I can add the PC monitor as a second monitor using HDMI/DVI and ensure that the outputs are mirrored AND that the VGA display is the primary.  However, on reboot it's as if the details are all forgotten!
    Searching around it seems that there are issues with Mac Minis and VGA connections to LCD TVs.  That said, I wanted to put my environment out there and see if anyone had an ideas.
    Interestingly enough, with older Mac Minis (without the tb/vga) it works perfectly well, indicating a problem with the new Mac Minis.
    Thanks for ANY ideas!!!!

    Hey Spost!
    You have explained exactly what happened to me last night.  I was afraid it was part of the 10.8.3 update or the latest ATV software update that hit this week.   I tried from my macbook pro and the airplay from 10.8.3 and the atv software worked fine.  
    Previously my mac mini was connected to a monitor in my basement but last night i made it "headless" and moved it to my "server closet"  airplaying prior to the move worked great ... then last night 4:3 Green Screen. 
    My guess is the computer needs to be connected to a external display in order for airplay resolution to figure itself out.   Via Logmein i could see that the Mirror mode wanted to use the resolution that fit the mac and not what was best for the Apple TV ... Even forcing the change made the setting go right back to this mac. 
    Looks to be a bug in a plist file that apple would need to fix as many people run headless mac mini's and now wish to AirPlay to their Apple TV's without the need for a external cable run. 

  • Mac Mini and LCD TV, changed resolution and now cannot use the screen anymo

    hello,
    I have a Mac Mini and and LCD TV which is connected via HDMI cable. I was playing around with the resolution settings (not very smart in hindsight) and managed to select a resolution that my TV does not support. I do not have another monitor or Macbook. Is there anything I can do to reset the resolution settings? I tried to reset the PRAM, but that didnt seem to solve the problem. I also tried starting in Safe mode but that didnt do the trick either.
    Appreciate your help!

    Arie, it may be possible to get to System Preferences via the keyboard. But you have to be sure the Finder is the foreground application. Is your Mac set to boot straight into your account or does it pause waiting for a password? If it boots straight into a user account, you can try the following procedure:
    \- Restart the Mac (It should be hooked up to the misbehaving display in case that's not clear)
    \- When it is done booting, type Cmd-Tab and then Cmd-Q. Do this several times. (Cmd-tab will step the Mac through all the programs that might be running. Cmd-Q quits them. Doing this several times ensures that only the Finder is running since the Finder can't be quit. This is important for the next step)
    \- Type Shift-Cmd-a (This should open the Applications folder)
    \- Type "sys" quickly (System Preferences within the Applications folder should now be highlighted)
    \- Type Cmd-o (This should open System Preferences)
    \- Type out the word "screen settings" completely (This should cause Displays to be highlighted in the System Preferences main panel)
    \- Hit the Return key (This should open Display Preferences)
    \- Hit the Return key again (This will clear any alert box that may have popped up)
    \- Hit the Tab key once (This will shift the keyboard focus to the resolutions list)
    \- Now start using the up (or down) arrow on the keyboard one press at a time. Each press of the arrow key moves to the next resolution in the list. Wait at least five seconds between arrow key presses for the resolution change to take effect. Hopefully, at some point, the monitor will light up with a stable image and you are back in business.

  • Mac mini and display

    any one can tell what is the best or posible display for mac mini 1.25mhz ? thanks

    Hmmm.
    As far as LCD's go, I have been doing a bit of research for the purchase of one.
    Consider first what you wish to use the computer for, LCD's are becoming fairly specialized, and typicall fall into these categories:
    1) Office/Word processing - Not too bright, so fairly easy on the eyes, not too fast, not too expensive. "action" in movies will not be as smooth or clear as on a CRT
    2) Professional Image editing - accurate colors, excellent image, fairly expensive, not too fast. Ditto about movies... these have excellent color, but response time for a LCD is much greater than for a CRT.
    3) Gaming - colors are inaccurate, may be bright, but very fast response. Probably not an easy monitor to sit in front of for word processing. Also, some in this category add noise to movies, so while the action may appear more fluid, you will have to contend with flashing and or off colors.
    There are a few monitors that fill more than one category, and I opted for one of these. Have a look at Tom's Hardware for a current review of LCD monitors for a better idea of what to expect:

  • Mid-2007 Mac mini and HDMI issues

    I have a Mid-2007 Mac Mini with OS X 10.7.3, that, most of the time, will work fine with a DVI->HDMI cable and either of 2 HDMI ports on the TV. The Mini recognizes the display correctly (a Vizio E371VL). The display's native res. is 1080p at 60hz, and the Mini is set to that and looks great. I can switch to lower resolutions and even restart the mini and have the Vizio look and behave correctly.
    However, I have an Apple TV (current generation - black brick) hooked up to the other HDMI port on the Vizio. It also looks and acts great.
    The problem is when I switch between the inputs on the TV. If I go to the Apple TV (which will be working fine) and then back to the other HDMI input, the Mac mini shows black. The TV does not say "no signal" or indicate any problem. No amount of zapping PRAM, ressetting the SMC or basic restarting helps. In fact, the TV still registers a signal at 1080p. Using Apple Remote Desktop from another Mac (a 2006 Macbook Pro with DVI) shows the Mini is still functioning and still correctly displays the Vizio model and 1080p @ 60hz resolution.
    The kicker here is that I can physically disconnect the DVI/HDMI cable from the Mac mini and connect it to the Macbook Pro. The video from the Macbook will pop up immediately. I can switch between the Macbook and Apple TV all day long, switch resolutions, etc. No problem.
    Even more bizarre is that this has the effect of "resetting" the Mac mini. If I plug the DVI connector back into the Mini, its video will pop back up. It will work fine as above until the HDMI input is changed again.
    Vizio tech support acted as if they'd never heard of Apple, Inc. Useless.
    Super frustrating problem.

    Opperman,
    I went with my gut and got an LG 47LM4600 TV with VGA input in addition to HDMI (seems there are not many--if any--TVs sold with DVI inputs anymore). The 2007 Mac mini is plugged in using my old DVI cable with VGA adaptor.  I tested it using the DVI cable with HDMI adaptor, and there was no sound.
    I can confirm the same condition that you originally described when I try to switch to the Mac mini on the PC input. The screen is black except for a color bar that flashes on briefly every 2-3 seconds at the bottom of the screen. No amount of switching from one input to the other will make the display come back. The only way I've found to fix it is to unplug the cable from either the TV or the computer and plug it back in.
    The annoyance with this is ameliorated by the fact that we'll be using a new Apple TV to watch Netflix from now on, instead of using a Web browser on the mini. Will only have to worry about it when watching DVDs.
    Cheers.

  • Is it possible to run dual display monitors on a KVM switch between my mac mini and a PC desktop?

    I have two 23" monitors utilizing DVI that I currently have plugged into my PC desktop.  I'd like to purchase the mac mini and utilize the same monitors for both systems and switch back and forth between the two.  So, I'm wondering if it's possible.  The only two hangups I can anticipate is dual display capability on the mini (I expect that some adapter will be necessary), keyboard compatibility between the two systems, and finding a switch that will handle all the above.  Any help would be greatly appreciated!!!!

    I think this video could help you
    http://www.youtube.com/watch?v=IYoC2teAbmE
    Other question is the switch box, You will have eight income cables (4 video, 4 usb) and four output cables

    I have a G5 PPC Dual 20" Mac Displays - I want to incorporate a Mac Mini and still use my keyboard and Monitors and Switch back and forth. How do I do this?

    The Hatter,
    I am a novice at Mac so I read all I can.  From what I understand the NEC monitors I bought require Display Port for their maximum performance.  The GTX 680 only has DVI outputs.  Difference from what I understand is larger bandwidth with the DP.
    You said I have the 4000 for CUDA.  I am not all that familiar with CUDA and when I do read about it I do not understand it. 
    A concern I have is, that if I connect the 2 high end NEC monitors via the 5770, using it's 2 Display Ports I would have nothing connected to the 4000.  Is the 4000 doing anything with nothing connected?  I read where in a PC system the 2 cards would interact but in a Mac system they do not.
    Bottom line, as I see it, the 4000 will not be useful at all to me, since I want a dual monitor set-up.
    So far the 5870 seems the best choice, higher band width than the 5770, and it has 2 Display Ports to optimize the NEC monitors.
    I'm not sure how fine I am splitting hairs, nor do I know how important those hairs are.  I am just trying to set up a really fast reliable system that will mainly be used for CS6 and LR4.  Those NEC monitors are supposed to be top notch.
