Hi all!
 
I recently upgraded to a 65-inch LG 4K TV. Prior to that I was using a 50-inch Samsung 1080p TV as my monitor. I'm using the same HDMI connector for the 65-inch as I was using for the 50-inch. Everything on the new 65-inch TV works fine and the TV has been updated to the latest software as of last week. I'm using the recommended 3840x2160 as my desktop resolution. 
 
Videos, games and movies all work fine and look amazing, but the issue I'm having is when browsing the internet. If the page is scrollable, the text will just vanish(sometimes partially) in the frame for no reason. Sometimes it cuts out and then comes back after scrolling a bit more, or less. It does not happen on every single webpage though, and after looking at the layouts of some of the webpages it happens on, I can spot no real reason or cause for it.
 
I'm using the latest 388.13 drivers(same drivers on both TV's). This happens with both IE and Chrome and is really perplexing.
 
I'm using Windows7 Professional - 64-bit - with all recent updates applied.
 
Anyone else experience this, or have any insights?

Does disabling hardware acceleration inside your web browser make the issue go away?

After closer examination is seems that Windows scaling and Nvidia's drivers(or the 760) aren't playing nice together. With the new 65-inch at 3180x2460, I had to enable windows scaling to the 150% level just to see my text and be able to read my icons comfortably. If I disable windows scaling, the problem in my OP goes away, but that puts me right back at square-one with my visibility issue.

It seems that the Nvidia control panel is somehow only recognizing a max refresh rate of 30hz for my 65-inch LG, but it is capable of displaying 60hz. I contacted LG about the scaling issue and they informed me that scaling is a function of windows(Win7 Pro) alongside the video card in use, but the refresh rate issue is a sole function of the video card/drivers and possibly the output type being used.
 
Could my scaling issue and refresh rate issues boil down to the fact that I'm using the HDMI output?
