Let's check the scores first.
Why yes, I will expect such terrible scores. ESPECIALLY on an external display with more pixels to push than the laptop LCD.
There is only a few fixes. Drop the settings to low or replace the laptop with some gamer PC.
Okay so I bought an RCA 32"tv a few months ago hoping to use it as a monitor for my laptop. After a few weeks of having the laptop connected to the tv via HDMI the laptop became quite slow and laggy. It lags all the time now, when I'm browsing the web or ingame. Anyway, so I bought Guild Wars 2 when it was released and all excited to play it I launched it and soon found that I was getting 10-25 fps. It was extremely annoying and unplayable. I first updated my drivers to the 304.79 beta drivers and still was having terrible performance issues. Next, my dad suggested cleaning the registry so I did that and launched the game. For some reason I was now getting 55-60 fps with great detail ingame. The whole computer actually ran much, much better than it had before. I was so happy and thought we had fixed it. The next day I connected the laptop to my tv again and that proved to be a grave mistake. The computer was back to it's terrible performance and all around general lag no matter what I was doing. I have ran the registry cleaner multiple times, I've ran malwarebytes and Spybot S&D, I've reinstalled the 304.79 drivers and still nothing is working. I can't even play GW2 because the lag is so unplayable. What can I do to fix it? My dad and I are all out of ideas since we've tried just about everything we can think of. Also, how can connecting your laptop to a tv damage it this bad? Or is that not the problem? Anyway, ANY help is appreciated. Please and Thanks in advance.
