The best use of CEA is as a tumor marker, especially for cancers of the gastrointestinal tract. When the CEA level is abnormally high before surgery or other treatment, it is expected to fall to normal following successful surgery to remove all of the cancer.he most frequent cancer which causes an increased CEA is cancer of the colon and rectum. Others include cancers of the pancreas, stomach, breast, lung, and medullary carcinoma of the thyroid and ovarian cancer.
Screen refresh rate is the number of times an image on any type of monitor or television is reconstructed per second. This is measured in hertz.. (Hz) For example, a TV witâ¦h a refresh rate 60Hz, reconstructs the image you're seeing 60 times every second. Basically, the higher the refresh rate on a tv, the representation of motion will be smoother, and the image will flicker less.
If you play games, refresh rate is something you might want to consider. Most monitors come with a refresh rate of 60Hz, which means you can only see 60 frames per second when you play (even if your game is getting 100 FPS, you can only see 60 of them on a 60Hz monitor).f your video card outputs in DVI, it'll be easiest if your monitor has a DVI port (though you can always get an adapter). Sometimes, certain cards will even place restrictions on certain port types (for example, only being able to power dual monitors via DisplayPort).
