Thanks for the quick reply, I put in the hdmi_enable_4k line and no difference.
My cmdline.txt is: console=0 user=glenda nobootprompt=local!/dev/sdM0/fs hdmi_group=2 hdmi_mode=82 hdmi_enable_4kp60=1 hdmi_cvt=2560 1440 60 3 0 0 1 max_framebuffer_width=2560 max_framebuffer_height=1440 hdmi_pixel_freq_limit=400000000 vgasize=2560x1440x16 It just seems like nothing I do really seems to make much difference.
