Sell it?

I use a monitor from Samsung. Its SyncMaster P2570. Old but still awesome for me

UE40F6510

It's serviceable and doesn't have any noticeable bad effects that would interfere while gaming.

The biggest problem lies in its technology. Due to its edge lighting it will illuminate the whole screen when there are light objects on it and in return will turn very dark if there are only dark objects. Which makes for an unnecessarily dark picture in dark scenes in video games or movies because it decreases the brightness as a whole and lowers contrast. Nothing that can't be fixed by cranking up the gamma but it annoys me.

I will keep this only up until I can find a proper OLED monitor.

Yours has a lower motion clarity index. Some TVs have a stupid option that makes it look like people are moving faster than they are to get rid of motion blur. Never use that, it lags games.

A cheap Viore LCD. 24 inches or something. Nothing special, but it works like a charm so far. I don't notice any input lag or motion blur on it. I've had it for 4-5 years now and it shows no sign of age yet.

i know it's shitty when WiiU gamepad run bayonetta 2 with smoother frame rate.

i'm too poor to change

I have the LN5700, which is the same screen as you have, but with "smart tv" features.  And I can see almost no motion blur.

Some PoS cheap ass 40" Soniq.
Basically Im too poor to buy a real TV and dont give enough fucks to save up for one.
Guess Im stuck with this one until it breaks.

A Sony KDL-46W950A.

It's awesome. :P

23-inch BenQ monitor I got on sale on Newegg over the summer. It's great.
