Hi, welcome and thank you for your question. My name is ***** ***** I am glad to assist you today.
Are you using a Viewsonic monitor as a second or extended screen for your laptop?
Please let me know by replying to me here so that I can help you further.
By A/B switch, are you referring to a KVM switch? Can you please tell me the exact model of that A/B switch you mentioned so that I can check its specifications?
Do you see a brand name there? Like BelKin? Or is it similar to this image linked below?
Let me understand your scenario further. You have a laptop and a desktop PC and you connect them to this A/B switch. So with this Viewsonic monitor, when you switch to A, you will see the laptop screen. And when you switch to B, you will see the desktop PC screen. Is that correct?
Thank you for that information. Can I remotely access your computers so that I can directly check the problem and fix it while you watch?
Remote access (Secure Remote Assistance) is an optional additional service offer with a minimal one-time flat fee regardless of how long it will take me to fix the problem. We can resume any time without additional cost. It is safe as you will be watching your screen and we can chat right there, and it will be a faster mode of help.Please let me know if you want this remote option.Best regards,Jess
Please confirm: Is the resolution messed up only when you switch to the desktop PC?
Oh ok. Thank you for that confirmation. Now please tell me, WITHOUT being connected to the A/B switch, what is the maximum resolution that the laptop can take?
Yes, please check that out and let me know. You need to check if the laptop's default resolution is 1920 X 1080
Thank you for that confirmation. So now it appears that the problem is with the laptop only -- when connected to the AB switch.
Have you tried to change the option under "Multiple Displays"? It is set to "Duplicate". Please check and test the other options.
What are the options under Display? (Multiple, Mobile PC and PnP Monitor?)
Thank you for that confirmation.
There is an online tool that allows you to maintain a desired resolution. I believe this will solve your problem. Please download the tool from this link:
After downloading it, extract the contents to its own folder.
I already set the config.cfg file to your desired resolution which is 1920x1080.
Now just RUN the program (Fixed Resolution App) and then try your AB switch.
While the app is running on the background, you cannot change the screen resolution of your laptop unless your END the app process.
I hope that helped.Please remember to rate my service positively (3-5 stars/faces) if this helped. Tips are always highly appreciated!
If you need further assistance, please do not rate me negatively with 1 or 2 faces. Instead, please reply to me so that I can help you further.
Oh sorry. Let me create a ZIP file instead. Here is the ZIP version.
Ok. I will upload the 6 files individually. Please make sure that you create a folder, you can name it like "FixedResolution" and then SAVE or store these 6 files in that folder. Then run the executable file from there.
Here are the links of the 6 files:
These 6 files must be in their own folder before you run the executable file.
Yes, I already set it to 1920x1080. You can edit it though, in your Windows 7 computer. Right click then choose Open With then choose Notepad. It is just a text file containing the resolution and refresh rate.
If you have stored the files in a spacial folder, please disconnect the laptop from the AB switch, run the EXE file (executable file) and then see if the system is displaying in 1920x1080 resolution. If it is, then connect the laptop to the AB switch then test if the resolution no longer changes to a lower one.
Thank you for writing back with that information. Please try to do this:
Keep me posted with your results so that I can assist you further.
Thank you for writing back and I am very sorry about the persisting issues. At this point, please follow these steps:
That is also possible. Please try to exchange the cable with that of the desktop. If the desktop's resolution is messed up and the laptop's problem is gone, the it is the cable.
Regarding step #6, I believe you were able to download the EXE file. Now to run it with admin privilege, right click on the downloaded exe file, then click Run as Admin instead of just double clicking on it to run.
I zipped the file, here is the download link:
Extract the EXE file then follow the rest of the procedures.
Please try to restart your computer then try running the EXE file again.
Hi, still unable to run the EXE file I gave you?
Thank you for writing back and I am very sorry for the persisting issues. Can I remotely access your computer so that I can directly check and fix the issues while you watch?
