A new 240Hz monitor should make games feel sharper, so low FPS right after the upgrade is frustrating - but it's almost always a setup gap rather than a bad part. Here is the order to work through before you spend anything.

Quick Answer

After a 240Hz monitor upgrade, low FPS almost always means the new part isn't actually doing the work yet: the wrong GPU is selected, Resizable BAR is off, or a power plan is throttling clocks. Fixing those usually restores the 20-40% gain you paid for. It matters locally because it stops you buying around a problem that a single setting change would have solved for free.

How to Pin Down Low Fps on a 240Hz monitor

Confirm the 240Hz monitor is actually doing the work: in the game's GPU/CPU overlay, check which part is at 95-100% load. If neither is, a power plan or frame cap is throttling you. If the GPU sits idle while frames stay low, the wrong GPU is selected or Resizable BAR is off. Each is a free fix worth real frames.

240Hz monitor Settings That Actually Matter

A 240Hz panel needs the GPU to actually push 240fps and Windows set to 240Hz - many setups silently default to 60Hz or 144Hz. Enable G-Sync/FreeSync in both the driver and the monitor's OSD so frames and refresh stay in lockstep. Use DisplayPort for 240Hz; many HDMI revisions can't carry it at full resolution, quietly dropping you to a lower refresh. As a yardstick, in Display Settings confirm the refresh rate reads 240Hz, then cap frames around 237fps with a low-latency mode for the cleanest feel, so use that as your pass/fail line rather than chasing a perfect number.

Reading Your Test Results

Treat the result as a buying guide. A problem that vanishes with a different cable, port, or sync setting costs nothing to fix. A problem that only shifts with more capable hardware tells you exactly what to budget for. That keeps SA spending sensible - you upgrade the 240hz gaming monitors or supporting part the test pointed at, instead of guessing and over-buying.

FAQ

What single setting helps low FPS the most on this setup?

For most users it's the sync and frame-cap combination: turn V-Sync off, cap frames a few below your refresh rate, and enable a low-latency mode. In display settings confirm the refresh rate reads 240hz, then cap frames around 237fps with a low-latency mode for the cleanest feel.

Is it worth booking the build in at Evetech for low FPS?

Only after the free checks. If a clean driver install, verified memory profile and correct sync settings all fail, a workshop test can confirm a faulty part - but most low FPS clears up at the settings stage.

Do I need to buy new parts to fix low FPS?

Rarely. The large majority of cases are settings, drivers, or storage placement - all free. Spend money only once a clean test still falls short, and then buy the one part the test pointed to rather than a full rebuild.

TIP

anything, run the baseline test above. Save your working settings profile once the low FPS is gone, then re-test after major game or driver updates. Only browse new 240Hz Gaming Monitors at Evetech if a clean, fully-tuned setup still falls short.
