I recently purchased a new laptop, a Lenovo U410 IdeaPad running Windows 8, and overlooked the fact that it has no VGA slot, only HDMI. This would have been grand were it not for the fact that my monitor, a HP 2159v, doesn't have a HDMI slot and can only use a VGA cable. I ordered a HDMI to VGA adapter from amazon (http://www.amazon.co.uk/gp/product/B00CH07AC2/ref=cm_cr_ryp_prd_ttl_sol_0) and it appeared to work fine at first. However when I tried to stream videos on Netflix or YouTube there were serious problems with buffering. Initially Netflix wouldn't even work and kept displaying a Microsoft Silverlight error screen despite the fact that I uninstalled and reinstalled it several times. I can only stream YouTube videos smoothly at low quality, around 240 or 144p. Both of these problems are immediately resolved when I remove the adapter and revert to the laptop screen. I can play high quality movies from my hard drive without any such difficulties so it seems to struggle only with streaming videos. I have tried downloading up-to-date drivers for the monitor but the problem still persists. Any ideas as to what may be causing the problem or how it can be fixed? Thanks in advance!
