| 549535 | 2007-05-13 12:55:00 | Just upgraded my sempron PC to a 17" monitor, and whenever I restart the PC, resume from standby or hibernate, it has gone to 60hz, even though in the settings it says 75hz. The monitor OSD says it is getting 60hz, changing settings to 60hz and then back to 75hz does nothing. I have to force 43hz interlaced in ATi control centre, then go to 75hz, where it actually goes to 75hz. (untill I reboot) I don't see how this can be a monitor problem, but it must be else why would it only do it with the new monitor? Radeon 9600XT Bravo with 7.4 drivers (latest) monitor says "µVision" on the front, and 'A Plus Info Tech Corp' on the back. AS-1770 is the model number. 75hz is supported, apparently, as the option is there when "hide modes this monitor can display" is selected. |

| 549536 | 2007-05-13 19:53:00 | AFAIK refresh rate isn't relevant with LCDs and defaults to 60Hz. | PaulD (232) | ||
| 549537 | 2007-05-13 20:55:00 | Both monitors are CRTs though... | Agent_24 (57) | ||
| 549538 | 2007-05-13 21:18:00 | Are the 2 monitors connected to the same PC? Or are the monitors, on separate PC's?? I had a similar prob (but with a TV connected to TV out). Since the TV was / is set @ 1024@768 the PC kept on going to this resolution. On every reboot. I had to change the resolution all the time. But, somehow, it fixed itself after 4-5 reboots. The LCD is now set at its default resolution. The ATI Catalyst Centre, maybe easy to configure, but the settings dont always stick. I would say coz if the 75hz was hidden, the monitor doesnt really support it. As it says hide modes that this monitor cannot display. |

| 549539 | 2007-05-13 21:58:00 | I had removed the 15" and replaced it with the 17", only one monitor is connected, I have used 2 monitors and 1 monitor and TV in the past but not currently. I have tried configuring it with the windows settings and the ATi centre, neither work properly. 75Hz is supported, it comes up when "hide modes this monitor cannot display" is checked. When it is actually running in 75hz it runs fine, picture is perfect, OSD says input signal is 75hz, no high pitched sounds or anything. Of course maybe it doesn't officially support 75hz, but I can't be sure because I cannot find any information on the monitor anywhere. |

| 549540 | 2007-05-13 22:06:00 | I would check the manufacturer's site. See what that says, or forget about trying to change it to 75 hz. | Speedy Gonzales (78) | ||
| 549541 | 2007-05-13 22:15:00 | XP may be defaulting to 60Hz because it is using a generic driver. The screen might be a JinSun try here members.driverguide.com | PaulD (232) | ||
| 549542 | 2007-05-13 22:15:00 | As I said, I cannot find the manufacturers site, and as you know, CRTs @ 60hz are bad. Powerstrip says it's an Acer API010D but of course Acer have never heard of this. I also tried the "write custom INF" in powerstrip, which reads data directly from the monitor EDID, so should be perfectly suited, I installed it with that file and it still does the same thing. I am going to try it on another PC later and see what happens. |

| 549544 | 2007-05-13 22:20:00 | You can set your monitor to a different one from the standard list in windows, pick one that supports the mode you want and that should fix things - just be careful not to choose a setting too high for the screen. also if you ever use a DVI - VGA adapter the refresh rate in windows has no effect |
