I recently bought a Catleap Q270 SE and I've been trying to get it to work on my laptop for some time. Originally I plugged it in and it gave me an immediate BSOD error - "Bad pool header". I thought of the many reg-edits as well as other customization I did with my OS so I have re-installed my OS and just did all of the updates / driver-installation. I know that the monitor only had a DVi-D dual link port which was fine since I acquired a 'high-speed hdmi cable' that is suppose to support up to 1440p. I connected this an adapter for dvi-d dual link and it proceeded to recognize it and not crash immediately. It simply keeps a green-flashing light.
My laptop is a Asus K53SV with i5-2410 (I believe). Intel HD graphics 3000 and nvidia geforce gt 540m, both of which claim to support 1440p (up to 1600p actually). I have done a complete clean install with my drivers. I will be doing another clean install momentarily since I was able to do 'Show screen on second display" as well as "extend displays' options before one of the drivers was installed and now it does not allow me to do either. It states: "Unable to save settings".
I have tested the monitor out with the DVI-D cable it came with on a crappier desktop in my basement. It is pixel perfect and works well. I do not have a desktop that has hdmi ports on it so i cannot test, yet, whether the HDMi cable - adapter set-up is currently at fault.
I wanted to know if there were any drivers you could manually download for these monitors and/or if anyone else has experienced something similar / tried it on a laptop with hdmi. I won't be building my desktop until the end of the summer so I am a tad bummed that I cannot use my monitor yet. D:
