Monitors with Native/Aspect Scaling

I recently got a U2412M for a client. It's a great monitor for the price, but I am disappointed that there is no native or aspect full scaling option. I will be sending 1080p signals to this monitor at times and it just stretches them vertically which is unacceptable for my application. 

Looks like I can go to the U2410? Are there other models that have this feature? Are there other size monitors with this feature that are also 1920x1200?

Thanks.
