So Iv been using this old tv for years as a primary screen on a DVI-HDMI cable 1366X768.
Today I changed cable to a display port- HDMI, and If I try 1366X768 it gets totaly blurry! I can use 1360X768 fine doh. Why cant I use the former resolution with the displayport setup?

When checking the advance settings, the best HZ for 1366X768 is 30HZ interlaced suddenly. How come no standard 60HZ? I just want to get the max resolution out of the screen on "720P", but it seems to jump into Interlaced 1080.

Running old Radeon 7770.
