i have a little problem with my mac and external tv (LG 4K).
Macbook air 2012 (intel HD 4000) LG 43UJ6307
i connect macbook with MiniDisplayPort -> DVI -> HDMI (1.4). by default i cannot set resolution to 2560x1440 (max resolut. is fullHD) but i fix it by switchResX app (but this only app can change this resolution more than fHD). when i set resolution to 2k fonts are vert uggly and readble. when i connect my Desktop pc and resolution to same size fonts are pretty and more understandable. (in 2k and 4k).
i was disable in Settings -> General -> Use LCD Smoothing when available
How can i fix it ?
i saw thereis option for HIDPI but there is only two variants 960x540 (HIDPI) 850x450 (HIDPI)
