I'm using the Acer G227HQL which is a 21.5" LCD IPS monitor for work and I really like it.
I've also taken it home and played GTA V (with my 970) on it and works really well.
I suppose the only problem then is that it has 1 VGA (D-sub) input and 1 DVI-I input meaning you can't have two of the same monitor given your 970. Perhaps you can find the Acer G227HQL version with HDMI which might exist. I think I saw it somewhere.
You might also have the same problem with other monitors given a lot of the smaller monitors may not have Display Ports.
Edit: If you do get that monitor you should play it safe and confirm that it does indeed have a HDMI port with the store, as the official website says it includes HDMI but mine does not. Link
Cheers.
So it looks like I'll need to get bigger monitors then. That's a pain but I should be able to re-arrange a few things.
Any ideas for bigger monitors to pair with a GTX 970. I don't know much about 1080 or 1440 so looking for advice there too
