Why are images not displaying at correct resolution in emails?

I've just upgraded to Windows 7 (64bit). Thunderbird is not displaying images at the correct resolution: images that I insert into the body of an email and images used in my signature. The images appear larger than they should and pixelated. It seems that images are not displaying at the correct resolution inside my emails, whereas in other programs on my machine images are displaying correctly. When I insert and image into an email using insert>image, the resulting "Image Properties" window displays the image's dimensions correctly. This confirms my suspicion that the resolution is not displaying correctly inside emails (a lower resolution than elsewhere on my screen, which would explain why the images appear bigger and pixelated).

I'd appreciate any help in fixing this problem.

What version of Thunderbird?

I have a vague recollection of a spate of reports of this effect, but that was a few versions back and the complaints about it have by and large dried up.

Thanks for responding Zenos.

Apologies, I forgot to mention that I'm using Thunderbird 24.6.0 in Windows 7 Home Premium 64 bit.

Thunderbird installed into the C:\Program Files (x86) folder. Is this the correct location, or should it be in the C:\Program Files folder?

I did try starting Thunderbird with add-ons disabled, but that didn't solve the problem.

I have an Nvidia GeForce GTx650 video card. Could that be affecting the display?

The Thunderbird I have installed is from a fresh download of Thunderbird into which I then imported my old emails and data using Mozbackup 1.5.1 (in case that has any bearing upon the matter).

Below is an image demonstrating the problem.

Hi Zenos,

I've discovered what is causing the problem, but I still need a way to fix it, if possible.

The cause of the problem is that in Windows 7 Control Panel > Display I have set the size of "text and other items" to 150% (otherwise everything is much too small too read on my screen's recommended resolution of 1920×1080).

I discovered that Irfan Viewer was also displaying at the incorrect resolution, but I managed to solve that problem by right-clicking on the IrfanView.exe icon and following Properties > Compatibility and selecting "Disable display scaling on high DPI settings".

I tried the same procedure with Thunderbird, but it made no difference. It is still displaying at the incorrect resolution.

Any suggestions?
