I hooked up my laptop to this monitor hoping to take advantage of a better refresh rate (144Hz) than it was allowing me on my TV (59Hz, despite this being a Vizio 3D TV capable of a refresh rate of 240Hz). I thought the problem with the TV was that because the cable was going first into a receiver instead of directly into the TV, that perhaps that was why my refresh rate options were limited.

However, running an HDMI cable directly to the monitor, it still only shows as options for refresh rates 60Hz and below. WTF? As you can see by the screenshot, the display adapter is correctly identifying the monitor as the ASUS VG278HE but it still only shows refresh rates up to 60Hz. (Unlike when I had it hooked to my TV through the receiver, the display adapter did NOT show a Vizio model whatever as the display, it instead showed what looked like the model number to the receiver. So I thought bypassing the receiver would allow me to increase refresh rates.

It's obviously not a huge deal, it's just I have noticed and was getting tired of the blurriness when I scroll on many games, and believed a higher refresh rate would help that.

Why won't my laptop let me set a refresh rate equal to what the monitor is capable of?

Well your question seems to be similar to this guys, perhaps that'll help.

I am not sure but maaaaybe the video card is to blame? Just shooting in the dark here, though.

Well, that does answer it, but I sure don't get it. HDMI cables can't support 1080p above 60Hz??? Really??? WTF???

I thought that was true of _old_ HDMI cables, but not today's cables. Mine specifically says "hi-speed HDMI cable" but according to that link no HDMI cables can support refresh rates over 60Hz at 1080p.

Just to check things out, I dropped my resolution down to 1280X1024 and then refresh rates up to 75Hz were allowed.

Hmmm, who knew HDMI cables were basically worthless.

Likely true, a laptop gpu will be designed and configured for the display it comes with. As long as hooking up an external monitor works it's "job done' considered for the laptop, asking a huge leap in performance isn't realistic, the laptop would probably just melt.

Well apparently your monitor supports HDMI 1.4 and 2.0 supports the speed to do 4K at 60hz, so 1.4 might just be too slow.

I don't know what you mean by "designed and configured", but at least the laptops I've tried can display e.g. 1920x1080 resolution fine through a HDMI or DisplayPort cable on a HDTV or external monitor, even though the native resolution (of the integrated screen) is lower. E.g. the native resolution of my work laptop is far lower than 1920x1080, but it can display that fine on my HDTV. So at least I haven't seen yet a laptop which can't display any higher resolutions on external screens than its native resolution, unless that resolution happens to be 1920x1080 of course.

Whether they have enough power to run modern games in that resolution is a different question though. Then again, there's normally no direct correlation to the gaming performance of the laptop, and its ability to display high desktop resolutions. For example my work laptop, when I'm running it at 1920x1080 on an external display device, it can show HD movies fine and older 3D games (if they have an option to run at that high resolutions), but for any newer games it doesn't make sense trying to run them in 1920x1080, but something lower like 1280x720.

It can run 1080p alright, but not at 144Hz or 240Hz, not in your dreams.
I also don't know what the HDMI standard is these days but in the past you had to use DVI if you wanted more than 120Hz.
