Monitor cable problems
« on: Sun Aug 13, 2017 - 18:19:47 »
So we are trying to modify Hubby's desktop computer setup and have run into a snag. The tower needs to stay next to the tv because we have lots of movies on a hard drive, but he wants to sit at a desk across the room, so I ordered a 50' cable to replace the little short one he has. This is the one I ordered:

It's exactly like the one I am replacing.

When I hook it up the monitor won't come on. It flashes on briefly - about as long as a blink - about every 10 seconds. In that brief flash we can see that it is showing the screen it should, it just won't stay on.

Any suggestions?

50' might be too long.  There may be signal loss.

Why would they make a cable that is too long to work?

Don't know.  Industry standard is met at 16 feet.  50 feet may work but it also may not.  From what i read 30' may be pushing it.

The problem occurs because the frequency set in your graphics driver is too high.
High frequencies can only go short distances, and low frequencies can travel much further through your cable.

How to change this:
If your graphics card has a driver application, you can open that application on your computer and set the frequency from for example 50Hz to 30Hz
Often the graphics driver also allows you to change progressive or interlaced signal. You can then find settings like 50p Hz or 50i Hz. Switching between these two may also help.
I suggest you start with the lowest frequency 30p Hz and then work your way up.

How to reach graphics settings from your Windows desktop.
Move mouse over your desktop. Right-click.
A menu will open. Select "Graphics Settings" if that's available in the menu.
Else select "Display Settings" and see if you can change frequency in the screen that opens.

Sometime you can find the frequency levels under "Screen Resolution".

AVZ, Thank you so much for your assistance. I was very much in hopes that it would solve my problem, but, alas, no.

My only options were 59p Hz and 60p Hz. It was already set on 59. When I changed the cable this time I noticed a message window that says "Input out of range. Change settings to 1680x1050 60Hz." It was already set on 1680x1050, and changing to 60Hz made no difference. Very frustrating!

Have you tried to bring down the resolution first? For example to 1280 x 1024?
After you confirm the new resolution, sometimes new frequencies become available as well.
