Comparing Monitors

When choosing between Plasma, LCD, OLED, and CRT display monitors keep in mind the following:

Cathode Ray Tube monitors can only go up to 43 inches, but LCD can be up to 108” and a Plasma screen can be as long as 150 inches.

LCD will consume very low energy, but CRT monitors will use a lot.

OLED screens have a higher risk of ‘image burn in’.

Bulk converting between image formats

Freeware available here, allows you to convert all files in a directory from one image format to another. Simply download the topng.exe to a folder containing the image files you want to convert. Press CTRL + SHIFT and right click and then select 'Open command window here'. Enter this command:

for %a in (*.bmp) do topng %a jpg

, , , to convert each .bmp to the .jpg format. To PNG handles the jpeg; png; gif; .bmp; and tiff formats.

Purrint

Purrint is another way to automatically save image files in Windows after pressing the PRTSC button. It's available for download here. [If you have the AutoHotKey executable running which was discussed in last night's tip, close it. It will stop Purrint from running.] It will give you the option to either copy a screen to the clipboard, print it as a hard copy, or save it as a file.

If you click on Options (then click on the cat to bring up the advanced options) you'll see you can set Purrint to automatically save files to a particular location, without it actually appearing. You can access the Purrint interface again by clicking on its icon in the system tray.

It's also possible to use Purrint to automatically save images at a set time interval.
