My 997DF has had a certain problem ever since I tried hooking up my laptop to it. The picture is horrendously stretched except at certain refresh rates. I use 1024x768, and 800x600. In the former, 85hz displays an accurate picture. In the latter 100 does as well. Any other refresh rate makes the entire screen distort. Again, before my laptop was hooked up to this monitor, it worked beautifully. What can be done?
Have you connected the laptop to another monitor and use the same refresh rates that cause the distortion? If the distortion appears on a different monitor, then I would have your laptop examined by a pc engineer, but, if the distortion only appears on the 997DF monitor, I suggest having the monitor checked at a repair shop, also, have you tried connecting the 997DF to a desktop PC, and use the same refresh rates?

not certain what that means but check the broadcast protocols that are options of the card's menus and the protocols the monitor can use.
Also check the maximum resolution of the monitor, the refresh rates it can support, the modes too and check that the settings on the cards software are not exceeding them, it may be that the resolution or refresh rates are beyond the monitor's capability to display
Right click on the screen. In the box that comes up select Graphic Properties. In the window that comes up click information. Box that comes up select monitor tab. Will have a list of display sizes and refresh rates that are supported by your monitor. Once you have that information you can make changes.
FYI: Acer says max resolution 1920 X 1080 with 75 HZ refresh rate.
Also if you have a tube light or speaker system close to the monitor then try moving it further away.
Are you sure the video adapter card is OK? A low-end video card may not
have the bandwith necessary to support high refresh rates at high
resolution. Just because the card will *generate* a given mode doesn't mean
that it will work well. Try the following steps.
1. Reduce the refresh rate to 60 Hz The monitor may seem to flicker a
little, but don't worry about it.
2. If there was no change, the problem is likely in the monitor
3. If that improved the resolution, then try removing any monitor extender
cables and play with higher refresh rates again. If that fixes the probem,
3. Replace the videa adapter card with a better one.
your screen refresh rates are governed by the graphics adapter in the computer so if it's not available, it's not available. for what it's worth, mine only has 60Mhz refresh rate. having looked at this range of laptops, it's unlikely that you would be able to upgrade the graphics adapter.
You need to reset the laptop video screen output resolution and refresh rate to something compatible with the HDTVs acceptable parameters. Consult the TVs owner's manual for a chart showing the acceptable screen resolutions and refresh rates. You are looking for numbers like 1024 X 768 or 600 X 800 for screen resolution. Your laptop will allow you to setup different screen resolutions for output. You just have to find one the TV likes.
did some thing change your refresh rates in the display section of your settings for the monitors? also have you tried to hook up another computer to see if it will display on the monitor? if nothing displays on the monitor then the monitor is faulty. if another computer (even a laptop) can display on the monitor then the video is set to high for the monitor to understand it. to reset monitor refresh with out a screen that will work you need to get into safe mode and reset the display settings to 60 hz and only 800 x 600 for starters and increase them until you cannot get a signal. if you cannot do this then a service shop will be able to assist you
