Try to update your drivers for your graphic card and see if that helps, but my guess is that your screen dosent suport higher mz than 60, everything above that will get you screen blurred or black.

Good luck!

Download and install the latest driver software for your video card to make sure that's up to date. Then make sure you've got the right monitor type specified and you should have the right choice of resolutions and refresh rates. If the particular monitor you have is not offered as a choice by your operating system, you can usually get specifications from the manufacturer's website. Then pick a generic monitor type that offers the highest refresh rate the monitor can handle.

After installing the ASUS EAH5450 my computer turns on and runs fine on my desktop monitor. However, I've hooked up a HDMI cable to my Sharp Aquos and the tv says it's receiving an incompatible...


The easiest thing to try is change the screen resolution before connecting via HDMI. The process is a little different depending on what operating system you're using.
For Windows Vista/Windows 7: 1. Right click on your desktop and select "Screen Resolution" 2. Slide the bar to change the resolution to either 1024x768 or 1280x1024. 3. Click apply.
For Windows XP: 1. Right click on your desktop and select "Properties" 2. Click on the tab to the far right that says "Settings" 3. Under Screen Resolution, slide the bar to change the resolution to either 1024x768 or 1280x1024. 4. Click apply.
Either of these resolutions should at least give you picture when you reconnect with HDMI. Once you get a picture, repeat these steps and gradually move the slider higher to get a better resolution picture. If you receive the incompatible signal message again, just wait 15 seconds and the previous setting will be restored.
If this doesn't work, you may also have to adjust the screen refresh rate. From the same window that has the screen resolution adjustment bar, click the link or button that says "Advanced." The second tab, "Monitor," has a drop-down menu to adjust the screen refresh rate. Depending on your HDTV, the most common setting for this could be 60 Hz, 70 Hz, or 120 Hz. If none of those values work for you, you should check the manual that came with your TV to check what the proper resolution and refresh rate should be for your computer connection.

Try starting windows in safe mode? This should force the settings to 256 colours and a better refresh rate. If not, you'll have to borrow another monitor temporarily and adjust the settings.

To avoid the problem recurring, you should be able to set a checkbox which says something like "Hide options that my monitor cannot display".

Graphics card problem


Shankar,

I looked up your Monitors specefications to try to confirm my theory. Which is that this is a resolution problem. Your Monitor is rated for a maximum resolution of 1024 x 768 at 68 Mhz so this is the max that your Video card can drive this at. However with a CRT Monitor running them at their MAX for extended periods of time can lead to the fuzzyness your talking about. Its likely that when you switched it to the On board or secondary videocard that it defaulted to the standard SVGA display levels of 800 x 600 resolution. Allowing the Video card to increase the refresh rate to 85Mhz.

Which coincidentally is what the Samsung recommends as the optimum setting for this monitor so I believe if you scale down to 800 X 600 @ 85Mhz I think this will clear up your problem. Though if your like me you like to maximize your screen real estate as much as possible.

There are alot of monitors in the market for around $100 USD that have "Native" resolutions of around 1280 X 1024 @ 75Mhz

Hope this helps you
Dave

Hi
There is no problem with the video card, for sure... it is the monitor has the limit. 100% sure. I have seen a lot, even screens limited to 800 x 640... Try a different monitor instead... use a 65-70HZ type to achieve higher resolution.

Give me a Fixya on this my friend... Post me more problems if you have.... C ya later.

Problems after installing drivers


Does this happen AFTER Windows has done a full boot up, or before?

If this happens after Windows has started, then the problem may be with the vertical refresh rate. Some monitors will shutdown if the refresh rate is set too high. To correct this, I would suggest loading your computer into Safe Mode, which should allow the video to work, and go into your video properties (right click "Desktop", select "Properties", click "Settings" tab, click "Advanced"). On the "Monitor" Tab will be a drop box for Screen Refresh Rate. If it's set to something above 80Mhz, try selecting a lower rate, such as 70Mhz. Other than that, I'm not sure. And no, you cannot use Remote Desktop to change the refresh rate as it doesn't use the video card to display with.

Using my tv as a monitor


Right click on desktop, then go to properties. Click on the settings tab. There should be two boxes, labeled 1 and 2. Click on box 2 and select:
Use the device as the primary monitor and Extend my Windows desktop onto this monitor. Also go to advanced -> Monitor and make sure that the screen refresh rate will not damage your tv. For older tv's it's usually 60 Hz for NTSC and 50 Hz for PAL.
After getting your settings where you want them, click apply. This will transfer all video output to the auxillary screen and will leave your primary monitor blank until you change the settings back to the primary screen.
