Hi, I have a Samsung Syncmaster 226BW Monitor that I bought from Overclockers about 12 years ago. It now flickers or the screen is too dark to see when first switched on. I have updated drivers and changed to a hdmi cable with adapter. It runs 1680x1050.Has the time come to buy a new monitor? My graphics card was changed last year to an Nvidia Geforce GTX 960 and I use Windows 7. I word process and play a variety of games. Do I need a TN Screen ? 4K? Or a Television would be useful (I tried a 10 year old tv and the text was blurry and unreadable). Is a tv ok or is it better to buy a dedicated monitor? Which one please ? Grateful for your help.
