Solaris8+patch display refresh rate problem

I have installed the 109401-05 video patch for Solaris8 to update the video
card drivers. But now at 1600x1200 screen resolution the maximum display
refresh rate is always 60Hz, altough higher settings in kdmconfig. The behaviour is similar at 1280x1024, but the max. rate is 80Hz. I have tryed
this with the ATI Xpert2000pro and Xpert98 graphic cards.
Without the patch the refresh rate is OK (with the Xpert98 card). The
motherboard is Abit KT7.
Does anybody know what could be the problem?
Thanks, Albin

Hmm, if the refresh rate was OK before you installed the 109401-05
video driver patch, why don't you uninstall that patch? Or do you
need some other bugfix included in 109401-05?
Otherwise the 60Hz problem problem with certain old ATI cards is not unknown to me:
See this Solarisonintel posting for a possible solution.

  • Poor display refresh rate during playback

    When I say "display refresh rate" I'm talking about the various toolbars,  level meter and the clock.  I'm not talking about the time coding like in frames  of a video clip vs. minutes/seconds/decimal but how fast those toolbars visually  refresh their information.  In Cool Edit Pro 2.1 they were real-time.  Level  meter and clock would refresh at the max speed of 61 frames per second (limited  by monitor).  However Audition refreshes at what I am guessing is around 12-15  FPS.  The level meter is like watching stop motion animation and the clock skips  along by fractions of a second instead of a smooth continuous spin.  That rate  makes the whole program appear sluggish and the level meter bars do not peak,  just the resulting tic mark appears.  The sound is fine and uninterrupted.
    It is not a hardware issue.  This is primarily a gaming rig  (Nvidia 280 GTX, X-FI Fata1ity, Intel Quad core, 4GBs RAM, Vista 64x, etc.).  I do  audio editing as a side job.  I've used versions of Cool Edit Pro for nearly a  decade on many machines including this one and I want to upgrade to a  multi-core/multi-thread version to make editing faster.  Is there a setting  somewhere to set faster display refresh rates?

    I don't think so. That would be the setting that replaces any form of Vista with XP, I suspect, and M$ thoughtlessly didn't add that... but you could try turning off every single service that isn't needed, and try unplugging any form of networking connection - the polling these do can screw the response of your entire system. That's why dedicated DAWs are built - to get around all of the throttling that your average or gaming PC does. Look for an app like EndItAll, and run it before processing audio. No, I don't know why it happens, but there have been problems with video displays almost forever with CEP/Audition - simply because as an app, it doesn't prioritise video.

  • PowerMac G4 533DA & HDTV - video resolution / refresh rate problem

    Hope someone can help, I need to access more resolution / refresh rates than I currently get in the Leopard display control:
    I have a PowerMac G4 533 Digital Audio running Leopard 10.5.8 (unsupported).  It has an upgraded AGP videocard, a ( flashed PC - RV200 chipset) Radeon 7500 w/ 64MB and a DVI output w/ a VGA adapter.  I have used this Mac perfectly with my 19" widescreen Samsung SyncMaster 940BW, at a resolution of 1440 x 900 / 60Hz / millions of colors.  This monitor is actually for my MacPro, but I used it for the G4 to set it up.
    I  moved it to my living room to use as a basic HTPC.  Since it runs Leopard, it has up to date VLC, Quicktime for video files and a working Superdrive for movies.  I don't expect it to play anything more than 480p properly, I think that was the best I got on YouTube.  But if I have a DVD ripped to DivX or MP4 it plays them fine on the Samsung monitor.
    I connected it to my Viewsonic N3760w 37" 1080 HDTV.  It turns on, gray screen w/ Apple and gives me a working desktop.  The problem is that I cannot get it to give me the correct resolution and more importantly it seem to have the wrong refresh rate.  It is currently set at 1280 x 768 / 60Hz / millions of colors.  The screen give me like a small line slowly moving up across screen, higher refresh rates only make it movie faster up the screen.
    According to my Viewsonic, these are the resolutions for computer using the VGA plug on the tv:
    PC - 1360x768 (preferred) , 1024x768, 1280x768
    Mac G3/G4/G5 - up to 1280 x 1024, 1280x720 (preferred)
    Please note all of these are lower resolution than my Samsung monitor.  My Viewsonic also has on screen adjustment of " phase " and " frequency " as well as the usual color, contrast, etc available.  Is there a 3rd party app to manually adjust the resoluion and refresh rate?  I have seen Windows programs, does one exist for Mac OS X?
    TIA, sorry for the long post

    My Viewsonic also connected by VGA, no problem.
    I wish I knew more. I checked out the app you did a trial of. I noticed this statement on their web site:  Quote
    "After rebooting monitor stays blank
    For some reason your monitor does not accept the installed frequency. SWITCH IT OFF!"
    This is the type of statement that would 'worry me.' -- having the phrase: SWITCH IT OFF! all in caps seems to imply a possibility of damage...which I mentioned in my initial post. (and the site goes on to talk about how you should even then connect another monitor to change the settings you've made that were not accepted).
    As I said, though, I wish I knew more for sure about this. It seems that you not only did the obvious of checking System Peferences>Display, but also realize the Viewsonic has buttons that can influence it's screen image, most about position of the image on the screen but at least one item about resolution on mine. (under Setup Mode)
    For what it's worth, my Viewsonic is about 6 years old now, still fine, and has eight (8) possible resolutions shown in System Preferences.
    Re: Your numbers.
    It is currently set at 1280 x 768 / 60Hz / millions of colors. 
    PC - 1360x768 (preferred) , 1024x768, 1280x768
    Mac G3/G4/G5 - up to 1280 x 1024, 1280x720 (preferred)
    If you're only talking about a difference of 1280 x 768 and G4 1280 x 1024, perhaps just stretching the picture using the Viewsonic buttons is the way to go.
    Or, from the numbers, perhaps the G4 just wants a resolution closest to it's preferred state!?
    Anyhow, good luck.

  • Ti4200-VTD8X (MS-8894) refresh rate problem

    I upgrade my Geforce3 Ti200 VGA to  Ti4200-VTD8X (MS-8894). My monitor is Samsung SyncMaster 955b (19").
    My problem is: I can not get refresh rate 1280/1024 85 Hz (This is the recomended rate of this monitor). I have instaled the newest monitor driver.
    Ah.. I have a 2nd problem. My OS is Win XP prof.  In the "display properties" window there is a place called "MSI information". In that window nearly all my VGA properties are wrong. It saya my memory is 32MB and SDRAM. AND i can not change the check boxes there. Can you please help me to solve my problems.
    Thank you,

  • Refresh rate problem with external 20 inch acer

    I am having issues hooking up an external montior via the dvi to vga dongle. The refresh rate seems shaky and the only refresh rate the computer gives me is 59.9 ?
    I recently had my logic board replaced and am not sure if this was an issue prior.
    thanks in advance.

    I've isolated the issue only happening when using taxing apps like photoshop. Seems to happen when the fans kick in.
    could this be an interference problem or possibly heat isssue?

  • Second display refresh rate lower in Mac OSX than Windows

    I use a Mitsubishi Diamond Pro 2070SB CRT monitor connected to my MacBok via a miniDVI to VGA adapter; I span the desktop on both monitors (i.e. I do not use the Mirror Displays option). I use this configuration in both Mac OSX and Windows (via bootcamp). On Windows, I can set the refreesh rate of my CRT monitor to 75 Hz at 1600x1200, but I am stuck to 60 Hz on Mac OSX at 1600x1200. To get a more respectable refresh rate on my CRT, I need to lower the resolution to 1400x1050.
    Obviously, the video card of the MacBook can handle a second display at 1600x1200 at 75 Hz since I can do that on Windows. Any ideas how to get the same result on Mac OSX?

    Either DisplayConfigX or SwitchRes X should be able to remedy this. But I am at a loss to explain why OS X would itself not allow for the 75Hz choice.

  • GeForce2 GTS refresh rate problem

    I have a GeForce2 GTS (MSI Starforce 815) running on an IWill KK266 (KT133A chipset) and a Sony GDM-400PS monitor. My problem is that when I set the refresh rate to "optimal" it runs at 60hz. This is a problem because my eyes are really sensitive to the flicker. I can set the refresh manually to a higher static refresh rate, and I can then switch back to "optimal" and it will adjust properly to a higher refresh rate but upon reboot it converts back to 60hz (although setting still says optimal.) I have several other non MSI GeForce2 GTS cards and they don't have this problem.
    Anyone have any ideas?
    To help weed out the suggestions:
    -running 350W Enermax PS, more then enough
    -running Win98SE (don't tell me to switch operating systems please)
    -Sony 400PS well within spec
    -have run 3 sets of Detonator drivers currently 40.72 same problem with all
    -I know I can set it to run at a static 75 or 85Hz but I prefer to have it adjust to the optimal setting for my usage.
    Thanks for any help!

    beavercleaver,
    I always set the monitors at 85hz.  It is a great frame rate that is really easy on the eyes.

  • T61p Wuxga display refresh rates

    Hi!
    I suspect that my GNU/Linux installation sets the wrong refresh rates for my 15.4" WUXGA 1920x1200 display. It sets the vertical rate at 50, which seems very low.
    I can't seem to find what the correct rates are in the documentation that came with the computer. Does anyone know? If you don't know the horizontal rate, I'm still interested in the vertical rate. What does Vista set? (I removed Vista, so I can't check myself.)
    Please help!

    Adamaxus -- searching the web I find a lot of such claims. I didn't know this. But I do know from my own experience that vertrefresh has a huge impact on my stationary lcd monitor. Are there different kinds of lcds that behave differently in respect to vertrefresh?
    Anyway, I don't have any flicker on my T61p screen. It only bothers me that xorg and nvidia-settings report different refresh rates, and that some GL applications might get the wrong info and slow down because of it.This is one of the explanations floating around the net for slow gl desktops on T61p.
    If 50 is the default refresh rate, I would think that xorg is right and nvidia-settings is wrong (it reports 60).

  • MBP display refresh rate

    MBP6.2, 8GB, 128SSD, GT330M 512 MB: when connected to a Dell U2711 monitor at 2560x1440 the only refresh rate available is 36Hz - is this normal? where can I get some more info about this kind of limitations?

    Are the grey tones in text mate based on patterned pixels? You may have to zoom the screen to check for sure. If so, and if it's an option, change to true gray tones from patterned ones and see if that fixes the problem.

  • IPad Air display refresh rate for full screen movies?

    What exactly happens if I play a movie on the iPad full screen with a rate of e.g. 24p, 25p or 50i?
    The stated maximal refresh rate is 60Hz.
    Will this rate be reduced when playing movies?
    Or will frames be dropped / interpolated if the frame rate and the refresh rate don't match?
    Or will the movie be sped up / slowed down?
    When using the HDMI adapter, I can see that it always outputs 60p, regardless of the movie frame rate. But maybe this is different on the internal panel.
    Thanks for any insight!

    Should it happen again double tap the screen with three fingers. Then go to settings> general> accessibility> zoom> off.

  • MacBook Pro 6,2 Display Refresh Rate

    I'm curious, can we get an official stat on this from Apple?
    For external monitors you can select a refresh rate.
    I'm assuming it's 60 Hz, but sometimes I'm convinced it's actually higher. There seems to be less ghosting than on any of my Windows machines, even though one of them has an IPS LCD screen.
    I'm assuming Apple doesn't use 120 Hz screens on any of its products, but it also seems impossible to tell!
    Note that this is useful to know for Syncing to Vblank in games and also for video playback, especially for stuff recorded in 24 fps.

    Apple uses 60 and 75 Hz typically.

  • JScrollPane visible part refresh rate problem

    I am writing an application that reads image and displays it in a JScrollPane via JPanel. It also has JSlider to set displayed image focus. The problem is that sometimes when big image is loaded and user changes seen part via scrollbars, the JScollPane refresh takes about 10 sec.

  • Refresh rate problem on sunstudio 8

    Dear gurus,
    I telnet to a sun server running solaris 9 from my desktop and whenever I run studio 8 and click/drag my mouse over the debug window which displays my source file, I get a gibberish display. The gibberish display takes a while to go away before the debug window brings back my source code.
    Could this be a problem with the difference in processing speeds between my two machines, or is it a network problem?
    Thank you for any help.

    You might be running into a compiler bug, but the sample code you posted can't be compiled. If you provide a compilable example, I can tell you more.
    But first, try compiling with no optimization options, and with +d (to disable function inlining). That will help narrow the range of possible causes.
    Since we're on the topic of -fast, let me add a comment about that option. The User's Guide contains some warnings about this option, with pointers to other documentation about the related options.
    The short answer is the -fast is not appropriate for programs that will run on machines other than the one that built the program. It is also not appropriate for programs that need accurate floating-point arithmetic. The exact effects of -fast differ among compiler releases, and sometimes from patch to patch.
    Production programs should not use -fast, but should determine the optimization options that are appropriate for the range of systems to be supported, and use just those. You should also conduct performance testing to verify that the options you select produce good results for your particular program.

  • 2511x refresh rate problem

    When trying to use a particular piece of software I get an error saying that I must change my resolution to 1920x1080 @60Hz.  when checking in my display and video card settings this is already the case, but when viewing the OSD is is showing as 1920x1080 @58Hz.  I reinstalled the drivers and rebooted and no change.  What can I do the change this?

    I've isolated the issue only happening when using taxing apps like photoshop. Seems to happen when the fans kick in.
