Just bought a Lenovo Ideacentre 3i from Currys. Decent price and it works, but I cannot choose my monitor's native display resolution of 3440x1440 via the HDMI output. This is the only one available, apart from the crappy VGA socket. I was using a cheap HDMI cable and tried a newer one, which cost £20 and I still cannot see the required resolution, in display settings. Every time I switch on the PC, my screen reminds me to use 3440x1440 for the best results etc. My work PC is fine, with this screen, via Displayport. I've also tried HDMI to Displayport cable, into the screen's DP socket. I also tried 50Hz refresh, rather than the default 60Hz. The screen is a Philips Brilliance 346P1C and looks great with the work PC, but on my new Lenovo, I have to choose a HIGHER resolution of 3840x2160 and it's squeezing and stretching and squashing the image and it's looking a right mess. I have to scale at 200% in order to see websites, otherwise I'm squinting at them, as I do with my 17" Dell laptop. This has now become the streaming device to my Audiolab Omnia and I rarely use it for anything else. Does anyone know why a new i5 CPU's onboard graphics and new HDMI cable, would not allow me to use the screen's native resolution, when an older chip, on my work PC, is OK? I've worked in IT, for over 20 years and I'm struggling.
