Dear Fred_Intel,
I check again TV's and monitor specification. Seem that TV 37LD465 natively support display resolution 1080p and 60 Hz over HDMI and monitor Dell U2312HM also natively support 1080p, 60Hz. I set this resolutions and refresh rates manualy for each display (1080p, 60Hz).
I agree for second issue that is about hardware change detection, although this fashion is too anoying. Some info ballon in right corner is way better solution, imho.
Thank You very much!
