Question about Hannspree HF237HPB 23 inch LCD Monitor

1 Answer

Hello. I have 2 Hannspree HF237 monitors. They each have this issue: When my display has gone dark after disuse (usually after 45 mins or so), and also when I wake-up my computer first thing in the morning, I can hear that my computer is waking up but the monitor display doesn't. When I tap the keys or move the mouse, the display is still dark. I have to turn the monitor off and then on, keep clicking and shifting the mouse and keys and eventually the display comes on. This is a progressive problem. My first monitor started doing this and eventually did not respond at all. Now I am on my second one and, while it started up fine in the beginning, it is now having the same problems as the first. Any ideas? Thanks for your help!

    I just tried it and it made my screen go dark. I pressed it again and it restored the display. Pressing the power button usually cues my computer to shut down (my MAC provides a prompt: Do you want to shut down your computer now?) but it didn't this time. Do you know why?

When your computer comes on black screen, just press the power button of your CPU and it will start displaying the monitor.

    If this still problems, I believe you need to update the monitor driver because when you installed it using your monitor driver CD, it get outdated and sometimes your computer gets awry. Just gets the latest monitor driver updates and installed it that compatible with the operating system.

    Try also to go to BIOS SETTING MENU by press F2 o Delete when start up booting and choose the power menu. Then choose WAKE UP PS2 KEYBOARD and save & exit. When you computer go black screen, use the keyboard to get display on your monitor.

When I boot my computer My HF237 monitor will briefly show the page then go dark. How can I diagnos the problem?

This is usually an issue with a failing capacitor. I replace them in mine often. In the monitor, on the power supply will be several capacitors (caps). Look for the tops to be domed these are bad. Try a site called badcaps if you are game to replace these.

A soldering station after shipping can be as low as $32 or so.

On laptops there is a key sequence that you can switch between monitor states, it's possible you have it in Laptop screen only. Look for the "Fn" key and then hit the Monitor button (it has a picture of a monitor) usually this is somewhere around F5 or F8.

Hannspree HF237 23" Monitor

The driver files allow for windoze to set the monitor up as a plug-n-play device. However, you do not need drivers to set this up manually. If you will right-click the desktop and open the display properties, click the display adaptor tab, and uncheck the box that indicates to hide incompatible settings (I don't have windoze myself, but it's worded something like that) save that change and click on the monitor tab, then find a compatible setting for your monitor as indicated in the instruction manual, you can set it up to work as well as if it had the drivers.
If you have any questions, please ask.

Error on monitor: Input signal out of range. using VGA cable and laptop is right next to monitor Hannspree 23" HF237 LCD monitor

Hello mcarsten,

Your monitor may not be configured to the correct resolution for the second monitor. If you right click on an empty space on the desktop and then select properties, the display properties will appear. Click on the last tab on the top right. It should be settings or something like that. You should see two boxes with the numbers 1 and 2 in them. Next click on box number 2 and try using the slider below and changing it to different resolutions for your monitor.

Hopefully one of these should work for you.
